Introduction

Within the category of cargo claims handled by our Club, cargo shortage claims occur at the discharging port.
For bulk carriers and tankers, as well as for general cargo and container vessels, a shortage claim arises
where there is a discrepancy between the quantity of cargo noted on the B/L (Bill of Lading) and the quantity
discharged.

Trends in Cargo shortage
and Case Studies

Cargo Damage including cargo shortage claims are the most common cases handled by us. Interest on the part ofour members is therefore high, and it is apparent that our members face difficulties in finding effective measures toprevent such trouble. This chapter summarises the trends in cargo shortage claims handled over the past 7 years, andintroduce cases in which caution is required.

2-1 Trends in Cargo Damage

In the case of cargo such as cereal grains, coal, mineral ores, and liquid tanker cargoes for which the quantity ofcargo on the B/L is shown by weight, the quantity measured at the loading port (i.e. the quantity noted on the B/L) and the quantity measured at the discharging port are compared, and any cargo shortage beyond the Trade

damage to a variety of cargoes while in the hold, and finally, cargo shortage. A total of 2,183 incidents of cargoparticular, with cereal grain cargo etc. for which the quantity noted on the B/L is determined by the Shore Figure

On this basis, a consideration of the simple average for insurance money per incidentof cargo loss shows that the insurance payment per incident of physical damage was approximately US$ 6,900, and(units： US$1,000)

the insurance money per incident of contamination loss was approximately US$ 38,000. While it is difficult to make

generalizations, there does appear to be a trend for insurance money to be greater for contamination losses. On theother hand, a consideration of cargo shortage claims reveals a fixed ratio in both the ratio of incidents and the ratio of
insurance money (21% and 19% respectively), with an insurance money of approximately US$ 10,000 per incident.
On this basis, cargo shortage is one type of cargo damage which cannot be ignored.

The average of insurance money per incident for container vessels was approximately US$ 6,000, indicating thatcomparatively small claims were common. If the container seal is lost on container vessels, and if a different sealis attached, the cargo interests may suspect that cargo has been removed/pilfered, and in many cases a surveyor isappointed and an investigation conducted.

Graph 7: Region of Incidents of Cargo shortage

Summary of Trends in Cargo shortage
Of the incidents handled by our Club, the largest number is related to cargo damage. Of these,
21% of incidents, and 19% of insurance money, are related to cargo shortage. Approximately
300 incidents occur each year, and the problem therefore cannot be ignored.
While the number of incidents of cargo shortage in container vessels is considerable, inpractice, cargo claims are often not made by the cargo interests and claims files are frequently
closed after payment of survey fees. However, there is always the possibility that insurancemoney further to the collapse of containers, loss of containers overboard, or the leaking /spillage of cargo into the sea, during the voyage may be considerable.
When considered in terms of the regions in which the incidents occur, particular care isrequired with bulk cargo (cereal grains etc.) in China, and unloading of chemical tankers (animaland vegetable oils) in Pakistan.

has its headquarters in Beijing (AQSIQ: Administration of Quality Supervision, Inspection and Quarantine), with
branch offices in various Chinese ports. CIQ is a government organisation recognised in Chinese law, and is primarilytasked with inspection of the quality and quantity of imports and exports, as well as quarantine inspection. When
Chinese Customs determines the amount of customs duty payable on imports and exports, CIQ inspection results are
employed as the sole official statistics, and when cargo claims develop into legal cases, the Chinese courts tend toaccept the cargo quantity based on inspection results provided by the CIQ.
Furthermore, surveyors from the CCIC (China Certification and Inspection), a division of CIQ, sometimes board thevessel and conduct draft survey.
Causation and BackgroundIn this case, a discrepancy was found between the quantity of cargo on shore prior to loading and that on the vessel at
the loading and discharging ports.

The quantity of cargo as obtained from the draft survey on the vessel at the Brazilian loading port was 65,994MT (thediscrepancy of 6MT was approximately 0.01% of the B/L figure), however the actual quantity on the B/L did not take
into account the quantity on the vessel, and was measured shore figure as 66,000MT. A shortage, albeit small, of 6MT
was noted at this point. The Master issued a Letter of Protest to the cargo interests and the charterers to the effect thatthe vessel was not liable for the discrepancy between the B/L figure and the ship’s figure, which was arrived at with adraft survey.
The draft survey at discharging port in China showed a figure measured by the CIQ of 65,374MT (the discrepancy
of 626MT was approximately 0.95% of B/L figure), the figure measured by the cargo interests was 65,686MT (thediscrepancy of 314MT was approximately 0.47% of the B/L figure), while the draft survey conducted by the Masterand the ship’s figure was 66,098MT (an additional 98MT), a considerable range of discrepancy.
According to our surveyors, the CIQ and the surveyors on behalf of cargo interests did not consider waves and swellwhen reading the draft, and noted that there was also a problem with measurement of the specific gravity of seawater.

A Letter of Protest (see attachment (1)) is issued by the Master if there is adiscrepancy between the shore figure or quantities from other surveyors and theship’s figures.
If possible, have the Letter of Protest signed by cargo interests and charterers.
When cargo interests ask the Master to sign associated documentation (e.g. draft survey records),
any signature must be accompanied by the remark ‘Without Prejudice, Receipt Only’. This remark
implies only that the document has been received, with no acceptance of the information given in the
documentation. The Master’s signature and remark have no effect on our members’ rights in later
claims. To addition of this remark should avoid unnecessary problems later on.

This example shows that a large discrepancy can arise information required for a draft survey is not gathered correctly.
Possible problems arising in draft surveys are set out in detail in Chapter 3.
The vessel also issued a Letter of Protest to relevant parties at the discharging port.

Prevention Measures
Preventive measures to eliminate discrepancies and to consequential problems are set out below.

It is essential to conduct a draft survey at both the loading port and discharging
port to determine the ship’s figures.
Verify the quantity on the vessel at the loading port and discharging port to determine how much has been loaded anddischarged.

In anticipation of shortage claims from the cargo interests, the following three documents
should always be verified, and the shipowners should obtain copies from the vessel.

Empty Certificate：Empty certificate: A document certifying that the quantity of cargo loaded on thevessel has been completely discharged.

Documents in addition to the above are required in some cases, and our members’ good cooperation is necessary toensure a smooth resolution of the claim. Furthermore, the three documents noted above are required not only in China,
but are the minimum required at all ports, and apply to all cargo.

We negotiate with the cargo interests on the basis of the ship’s figure as noted above when the cargo interests makea cargo claim. If the ship’s figure cannot be verified, there is no basis to defend the alleged cargo claims, and our

which have arisen, it may be difficult to keep the CIQ surveyors on board until our surveyors’ arrival. It is therefore
recommended that surveyors are appointed in advance, and the details of methods of inspection, procedures, andconditions etc. discussed and settled between relevant parties before the draft survey begins.

It is important to be aware that Chinese courts are not governed by precedent, and that decisions differ by jurisdiction.

Cautions for Cargo shortage in China

A decision followed by one court may not be followed by another. In particular, different courts have different
understandings of Trade Allowances (generally 0.5% of the quantity on the B/L). The Trade Allowance is, basically,

The figure measured by the CIQ is the key point

not recognised in the Qingdao court. However, most courts other than the Qingdao court have accepted the Trade
Allowance to varying degrees in decisions, and this provides an avenue for negotiations.

As explained above, the quantity of cargo received by the consignees is defined by the figure measured by CIQ. In
other words, if the CIQ figure is less than the B/L figure, a ‘cargo shortage’ is naturally assumed. Fundamentally,
courts tend to accept the CIQ figure, and it therefore always necessary to establish and maintain good contacts andcommunication with the CIQ surveyors in order to ensure accurate measurements.

Under Chinese law, the carriers are not liable for cargo shortage due to ‘natural loss’, i.e. the damage or loss fromthe nature or inherent vice of the cargo. Bulk cargo may diminish in transit, with the moisture content of the cargo
evaporating, resulting in a reduction in the loaded quantity. For example, the moisture content of cereal grain cargosuch as soybeans evaporates in transit. In this case, the certificate noting the quality of the cargo at the loading port
also includes the moisture content of the cargo. It is therefore necessary to analyze and compare this value with the
moisture content at the discharging port, and certify that the decrease in quantity has evaporated during the voyage.

Resolve claims smoothly

Certifying ‘natural loss’, in other words, the amount of evaporation during the voyage, presents considerable difficulties, but if it is recognised, ensures a high probability of a successful decision in favor of the vessel.

Chinese law does not provide for a time-extension of cargo claims, and the cargo interests must make a claim against
the party causing the cargo loss (basically, the carrier on the B/L) and finalise the claim within one year after theconsignees received the cargo. Although dependent on the amount of claim, a claim is very likely to be referred to a
court, if not resolved within the time-limit. If, therefore, our members receive a cargo claim, it is important to maintaina close exchange of information with us to ensure awareness of the time-bar in resolving the matter.

While differing from the ‘natural loss’ described above, water from cargo having a high moisture content (e.g. ironore, coal, nickel ore) collects in the bilge during the voyage. Water is sometimes sprayed on the said cargo for environmental reasons during loading operations, to prevent dust escaping, , and to protect the health of workers. In suchcases, water collects in the bilges during the voyage, and must be discharged, so that, even if the quantity on the B/L isdetermined from the draft survey at the loading port, the B/L figure includes water applied during loading. Therefore,bilge water discharged during the voyage technically contributes to a cargo shortage at the discharging port. However,Court Judgments

needless to say, this has no effect on the actual quantity of cargo. At the same time, there is always the possibility that

If possible, have the Letter of Protest signed by the cargo interests and the charterers.
While unloading in Pakistan, there were no communications or reports of problems
related to cargo shortage, and the vessel, charterers and shipowners were unawareof any problem, so the claim came as a great surprise.

raised in court despite there being no report from the cargo interests of any cargo shortage etc. during discharge, andalways to be prepared for such a claim.

Pakistani courts
Under Pakistan law, the time-limit for cargo claims is one year after the consignees receive the cargo, however inpractice it frequently takes a considerable time for the shipowners to receive the complaint from the court (2 years
and 4 months in this case). These delays are due to the very long periods of time required for internal processing inPakistan courts. Based on the complaint, it can be assumed that the cargo claim itself is valid if the cargo interests

3-1 Timing of Measurement at the Loading portraise a cargo claim in the court before the time-limit.
Furthermore, since the complaint is often sent to the shipowners and charterers via the local agent, it is necessary to
instruct the agent in advance to notify relevant parties without delay once the complaint is received.
In the worst case, the agent delays notification of the complaint, and it is too late to appear at the first sitting of thecourt, not only will the shipowners be at a disadvantage in the court's decision, but, depending on the amount of theclaim, the vessel and its sister ships may be arrested by the cargo interests on the next call at Pakistan ports. If the vessel is arrested, it is important to note that the considerable time required for internal processing of claims in Pakistan
courts will affect the ability of the vessel’s departure.

When the quantity of cargo is noted on the B/L (e.g. bulk carriers, tankers) by weight, the quantity of cargo loaded
must naturally be measured at some point in the loading process. The question of when to take the measurement of
the quantity of cargo is determined in the freight contract between the charterers (the operator issuing the B/L) and thecargo interests.
Sailing instructions given by the charterers tell the vessel which figure is to be taken as the loaded quantity in the B/L.
It is necessary to check with the charterers if no instructions are given.

Broadly, measurement is carried out at the following points.

The large number of small claims in Pakistan involves considerable expense and time, and many cases are settled
out of court. Unfortunately, the trade allowance is not accepted under Pakistan law, and also there is a tendency for
judgments advantageous to the cargo interests. So, this makes quick settlements desirable. In recent years, out-of-court

In the Age of Sailing Ship, since the vessel needed to dump cargo to the sea in order to avoid the her distress/
shipwreck, there is possibility of a cargo diminished during the voyage. Today, however, there is no contact withcargo during the voyage. If, therefore, measurement at the loading and discharging ports is accurate, and excluding
cases in which the moisture content of cargo evaporates during the voyage, or the cargo itself evaporates, the loaded
and discharged cargo quantities should be the same.

3-3 Causes of Discrepancy in Measured Weights of Loaded andDischarged Cargoes.
While theoretically the same, the following causes for discrepancies in loaded and discharged cargoes are possible.

Furthermore, if the last cargo from the previous voyage remains in the bilge well, it will block discharge of bilge
water. However, while this bilge water was measured as cargo at the loading port, since it cannot be discharged as the
cargo, it will be seen as a shortage in the discharged quantity.

Sounding Pipe

It is therefore necessary to clean the bilge well and take measures to ensure that cargo cannot enter (e.g. cover thebilge well cover with burlap) before loading operations.

There are very few cases of reduction in volume of cargo during the voyage.

will be a reduction in the documented quantity of the cargo.
Brazilian iron ore has a particularly high water content, and is sprayed with water during loading to prevent dust.
A considerable amount of bilge water is therefore unavoidable, and may reach approximately 2,000MT (1% of thequantity of the loaded cargo) in some cape size bulk carriers.

As in 3-1 (1), when the measurement point is on the conveyor belt in the storage yard, or when the cargo is transferredto the loader, cargo spilled after measurement and not loaded onto the vessel will naturally reduce the actual quantityof cargo loaded.
In cases of heavy rain or water spraying to prevent dust during loading, the cargo absorbs water after measurement
and the full load is reached earlier than scheduled due to the weight of this water content. If this is then discharged asbilge water, the discrepancy will be large.

Due to the natural loss of the cargo itself

While rare, natural loss due to evaporation can also occur with some solid cargoes such as camphor (used as an insect
repellent for clothing). Sailing instructions include a number of precautions when loading such specialised cargoes.
Prior consultation with the charterers is necessary on methods of dealing with the problem. For example, it is important to take measures to prevent cargo shortages through natural loss by clarifying the trade allowance for the durationof the voyage, and commissioning a draft survey to determine the loaded and discharged quantities.

transfered bt truckat SiloIn the case of tankers, the cargo has a high volatility and the effects of improper sealing of tanks (e.g. manhole

PV valvesPilferage

Spillage of cargo on the way to the measurement point after discharging from the vessel at the discharging port results
in a cargo shortage. In particular, it has been reported from ports with low standards of management that when cargo
is loaded onto trucks, each truck is inspected but after this the cargo is pilfered by the truck drivers, which results in ashortage of cargo.
【Prevention Measures】
It is difficult for the vessel to take practical measures when the loaded and discharged quantities of cargo aredetermined by shore figures. Even when loaded and discharged quantities of cargo are determined by shore figures,the vessel should conduct a draft survey, and if a discrepancy is found in the quantities, a Letter of Protest etc. should

be prepared in response.

PV valves operate automatically for tank protection, venting to atmosphere if pressure becomes excessive,
and taking in air if pressure becomes negative. Each valve is set to operate at an appropriate pressure.

What is a draft survey?

This section explains the principles behind using a draft survey to calculate the quantity of loaded cargo.
Main Discharge LineFirst, the reason that a vessel constructed of steel is able to float can be found in Archimedes’s Principle.

In most tankers it is not possible to visually inspect the cargo and tank inside to determine whether or not any cargoremains. The eductor intake pressure is therefore checked to determine whether or not the tank is dry. In such cases, if
the attitude control of the vessel is incorrect and the liquid cargo cannot be collected at the intake pipe, it will not be
possible to discharge the full quantity of cargo.

Archimedes’s Principle「A body immersed in a fluid is subject to a buoyant force equal to the weight of the fluid that it
displaces.」This principle is used in the draft survey to measure the total weight of the cargo and thevessel, and the weight of items other than the cargo is then subtracted to find the quantity of cargo.

(2) Accuracy of the Measurement equipment in shore facility and on the vessel
The OIML (International Organization of Legal Metrology) is an international weighing and measurement organization working towards improving the accuracy of weighing and measuring instruments, however policies vary between
countries so that no uniform policy is possible in practice.

If the calculated indeterminate weights (constant) exceed this value, or becomes a negative value (an extreme= Errors in measurement of thespecific gravity of seawater =case), an error is therefore assumed in one or more of the values, and each must be verified again.

This section considers errors in the various values subtracted from the gross tonnage, and the values read from thedraft marks, when calculating constants or when calculating the quantity of cargo after loading is complete.

A seawater gravimeter as shown at right is generally used on the vessel.
With the seawater gravimeter it is desirable to measure at the seawater surface, the mid

The accuracy of the seawater gravimeter cannot be guaranteed in some cases. Ensure that reliable equipment ispurchased.

= Measurement errors withvarying weights =To determine constants and cargo quantities, the weights of items associated with the vessel, e.g. fuel, lubrication oils,
freshwater, ballast water, are subtracted from the gross tonnage found by measuring the draft. Errors in these varying
weights result in errors in constants and cargo quantities.
Since the tanks for fuel, lubrication oils, and freshwater are small, weights can be found very accurately with precise
sounding.
Of the varying weights measured, large errors are most likely in ballast water, and accurate measurement is required.
A particular example is bulk carriers using holds as ballast tanks. Large errors in measurement of ballast water in theholds are noteworthy in such cases.

When in dry dock, therefore, it is necessary to put out a boat and measure the waterline with a ruler in order to accurately determine the waterline, and to calculate the constant as a reference value until the next time the vessel enters
dry dock. Sufficient time is unavailable during loading to conduct a draft survey.
With Capesize bulk carriers as about 180,000 Dead Weight, an error of 1cm in the reading results in an error of
119MT.

In other words, while other factors also affect the result, rolling of the vessel causes the liquid level in the tanks to riseand fall. If the vessel is rolling, therefore, multiple soundings should be taken as with draft measurement
With trim and heel (an incline across the axis of the vessel from port to starboard), in particular, it is possible to obtaina comparatively accurate value from the measured draft, however it is important to calculate using the draft marks
amidships and to take the width of the vessel into consideration, rather than use an inclinometer.
On the other hand, if the vessel is twisting it is impractical to take detailed measurements of the angle of inclination.
Devices other than inclinometers are also possible. In dry docks it is not uncommon to see a weight on a string fixed－ 28 －－ 29 －JAPAN P& I CLUBJAPAN P& I CLUBP&I Loss Prevention Bulletin

The Capesize bulk carrier as about 180,000 Dead Weight has a load of 157,653.949MT with a trade allowance (0.5%of the quantity on the B/L) of 788MT.

Measures to minimize the errors in weights of these varying items are as follows.

A 3cm error in the draft reading, and an error of 0.001 in the seawater specific gravity measurement, results in an error of 538MT.

Loading port for Bulk Carriers
The timing of measurement at the loading port was explained in 3-1. This section explains the method of determining
the quantity of cargo loaded in practice.

The following explains the basic procedure for the stowage plan.

1

The charterers provide the sailing instructions for the next voyage. These also
include instructions for the quantity of cargo. The specified quantity of cargo± 5% is generally set as an option for the charterers, shipowners, and Master.
It is considered important to load as much cargo as possible, and to minimize
fuel replenishment and freshwater on hand.

(1) Determining the quantity with a draft survey
The cargo interests (shippers), charterers, and shipowner conduct a joint draft survey in many cases. This survey is
noted in the sailing instructions. It is necessary to verify with the charterers if this is not clearly noted.

2

The quantity in each hold is often found by dividing the total quantity of cargo as calculated from the draft survey
by the figure for each hold on the shore scale. There is a possibility of error for each type of cargo when two or moretypes are loaded and a draft survey is not taken for each.
While a first officer, the author had the experience of loading six types of coal on a nine-hold Capesize bulk carrier

A stowage plan is then prepared and approved by the charterers, and theloading sequence prepared. This documentation is sent to the stevedoring
company (Refer to the attachment ④ : Loading Sequence).
Calculate the amounts of fuel, lubrication oils, and freshwater, and the3constants, after entering port, and consult with the stevedore company on any
fine adjustments necessary. Always calculate the constants before loading.
Even if the quantity of cargo loaded is determined with the quantity shore, asurveyor should be engaged if possible for verification.

at the port of Gladstone in Australia. The sailing instructions specified that the quantity of each cargo was to be calculated with the method described above. To ensure a more accurate understanding of the quantity each type of coalloaded, the charterers asked if it was possible to take a draft survey after loading of each type of coal was completed,however problems were recognized with vessel strength calculations in the loading sequence plan, and the request was

been prepared in accordance with the loading procedure, at each juncturein the sequence, verify against information received to ensure that work is

negotiations, legal proceedings (either in court or arbitration) will be unavoidable. In such a case, competent lawyers

Vessels receive cargoes from shippers at loading ports and deliver them to consignees at discharging ports. If there
is a short delivery, consignees or subrogated cargo insurers are likely to pursue a cargo shortage claim against the

Evidence provided by cargo interests

When cargo interests make a claim, they have a duty to establish that their cargo has suffered loss and/or damage.
Generally, they have to show that :1

carriers. Consignees or cargo insurers will be referred to below as 'cargo interests'.
Cargo shortage can occur at loading ports or discharging ports. Typically, when the cargo discharged at the discharging port is less than the B/L figure, the consignees will immediately notify the carriers of the shortage of cargo. A
shortage claim will subsequently be lodged by cargo interests. For the purposes of clarity, we refer to the former as a'claim notice', and the latter as a 'formal claim'.
Often, a demand for security will be made by cargo interests to cover their claim for the alleged shortage, either before
or after the formal claim. Such request may not necessarily be requested only after completion of discharging. If cargointerests determine that there is a high probability of a cargo shortage as a result of a draft survey during the discharging operation, security may be requested at a very early stage of discharge. Unless carriers issue a letter of guarantee,
cargo interests are likely to begin the process of arresting the vessel and/or preventing the vessel’s departure. In suchcases, we (P&I Club) will issue a letter of guarantee for the cargo interests’ claim in order to avoid an arrest or releasethe vessel from arrest, subject to wording and quantum of the claim being agreed.
When a formal claim is received, we will seek to collect the relevant documentation, review the reasonableness of theclaim, including merits and quantum, and if appropriate, negotiate with cargo interests (which process is discussed
later).

When a B/L is issued, the cargo quantity stated on it is assumed to be the shipped quantity. If cargo interests submit
documentation showing that the actual quantity discharged is less than the B/L quantity, it is assumed that a shortage
has occurred during the voyage, and that cargo interests have suffered a loss equivalent to the value of the shortdelivered cargo.
Having said that, the liability of the carrier only extends as far as his reach of operations. In other words, it isunderstood that the period of carrier’s liability ends with the discharging of cargo from the vessel (tackle-to-tackle). In
the case of dry bulk carriers, the reach of the carrier is within the ship’s side of the vessel. In the case of tankers it is
up to the manifold. Even if a cargo shortage has occurred, if it can be established that such a loss occurred beyond theship’s side of the vessel, or beyond the manifold, it is possible to argue that the carrier has no liability for the alleged
shortage
Various exemptions to liability are provided to carriers by international regimes, such as the Hague Rules etc. These
exemptions are based on the concept of liability of the carrier for losses being limited to their reach of operations. In
some cases, the carriers may be exempt from liability for cargo damage under the terms and a conditions of the B/L or
the charter party.

In the event of a successful settlement, an agreement will usually be drawn up recording the terms of the settlement
which is signed by both parties. Once the settlement money is paid to the cargo interest, the claim is finalised. If a
letter of guarantee had been issued for the claim, it should be retrieved and cancelled.

● When there is a possibility that trucks carrying cargo may bypass the weighing station andgo directly to the warehouse, resulting in cargo shortage.

In terms of showing that there has not been any actual cargo shortage, or that any cargo shortage could not haveoccurred during the vessel’s custody of the same, the following practical measures may be taken.

While many of the claims for cargo shortage are thought to be due to inappropriate loading and discharge operationsand variations due to differing methods of measurement, it is very difficult for the carriers to record these fully, and●● or dry bulk cargo, seal hatches after completing loading, and have the intact sealF
witnessed and recorded before opening the hatches at the discharge port to establishthat no cargo has been removed during the voyage.
 or cargo which has a tendency to produce free water during the voyage, carefullyFrecord the amount of bilge water discharged, to show that any loss in weight of the
cargo can be explained by the discharge of free water.

records of cargo quantities.

●In order to establish that the carrier has delivered the full quantity of cargo which was
loaded at the loading port, keep empty and dry-up certificates before loading and after
discharging.

Regrettably, even if prevention measures are satisfactory on board, cargo shortage may occur at the discharging port
in areas, beyond the control of the vessel. In such case, a competent surveyor is recommended to monitor discharging
operations.

since it is not easy to establish that the carriers are not fully liable for such problems, they may have no other choice
but to agree an out-of-court settlement in some cases. As such, if the vessel can document the details of inappropriate
discharge operations and methods of measurement for shore figures, this may be useful in defending a claim.
As explained in '4-4 Recovery Action Against the Charterers and Shippers below, in some charter parties, such as the
SHELLTIME 4 form, when charterers give instructions for the signing of the B/L, the contract may provide for thecharterers to indemnify the shipowners and hold them harmless in respect of any liability, loss, damage or expense
by reason of the Master's signing of B/Ls at charterers' request. Therefore, it is recommended that a similar clause be
inserted, if possible, when negotiating charterparties and/or fixture agreements.
■

Responding to a discrepancy between shore andvessel measurements of the quantity of cargo at the load port

If the discrepancy between the quantities of cargo measured by the vessel and that stated by the shippers at the loading
port exceeds the range of measurement error, please contact us or our local correspondents directly. In some cases, thediscrepancy may simply be due to a mistake in calculation or measurement. In this case, a re-survey by surveyors tocheck the cargo quantity should dispose of the dispute.

In addition to the crew measuring the quantity of cargo, an independent surveyor could be appointed to provide a
record of the measurement and the process of discharge, which can be used to prove the quantity of cargo discharged,
the process of measurement, and if appropriate, to support the argument that cargo loss has not occurred during thevoyage. Appointing a surveyor is also recommended when loading and discharging in areas where shortage disputes
are common.

If a mate's receipt and B/L are issued for the quantity declared by the shippers, notwithstanding a discrepancy with thevessel's own loaded quantity, in so far as cargo interests are concerned, it will be assumed that the quantity of cargostated by the shippers i.e. the B/L quantity, has been loaded onto the vessel, and defence against a shortage claim
arising from such a discrepancy will be difficult.

A surveyor’s work need not be limited to measuring of the quantity of cargo. In the following cases it is advantageous
to have the surveyor monitor the loading and discharge of cargo as well.
The following practical actions may be taken when there is a discrepancy in the quantity of cargo at the loading ports－ 34 －－ 35 －JAPAN P& I CLUBJAPAN P& I CLUBP&I Loss Prevention Bulletin● Issue a Letter of Protest in relation to the discrepancy in the quantity of cargo to establishthat there is a short loading and the loss of cargo has not occurred during the voyage.

4-3 Negotiations After Receiving a Formal Claim
If a formal claim is raised, we will normally seek to conduct settlement negotiations with the cargo interests in order
to settle the claim. Usually our claims handlers negotiate directly with the cargo interests, but where appropriate, ourlocal correspondents and/or lawyers may be appointed.
Defence against shortage claims can broadly be classified as either factual or legal.

(1) Factuall defences
Factual defences, as the name suggests, are based on facts. The following points will be investigated, and if the facts
support arguments that the vessel is not liable for the cargo shortage, these facts will be asserted to the cargo interests.

● N otify the charterers and request participation of their surveyor to record the quantity ofcargo loaded, to assist in any potential recovery action against the charterers.

D‌ id the cargo shortage occur during the vessel’s period of responsibility?
W‌ as loading/discharging operation appropriate?

Often, when there is a discrepancy in the quantity of cargo at the loading port, charterers may request shipowners not
to clause the Mates receipt or the B/L stating the actual quantity loaded and return for a letter of indemnity (LOI).

W‌ ere there any errors in measurement or calculation by the cargo interests?

Rep 1, p.13) on the basis that it was a conspiracy between the shipowners and charterers to defraud the consignees.
Shipowners should therefore take note that an receipt of an LOI in these circumstances may not be risk free.
■ Responding to cargo shortage at the discharging port
Cargo shortage claims are likely when the following situations arise:● he results of a draft survey show that the discrepancy between ship's figures andTshore figures exceeds the normal range of tolerance.

●

The Master receives a Letter of Protest about cargo short delivery from receivers.

●

Spillage/pilferage of cargo during discharging operation.

In such situations, please instruct the Master to prepare a clear and detailed Statement of Facts, and contact us. Of
course, the Master can contact our local correspondents directly through the local agents as well. We will also appoint
a competent surveyor to investigate the cause of the cargo shortage in preparation for any potential cargo claim.
In some cases, cargo interests' surveyor may ask the Master to sign documents noting the quantity of cargo discharged.
If the documentation is signed without objection, this will be interpreted as the Master accepting the contents of said
documents. The Master should therefore try not to sign such documents. However, if he has no alternative, he shouldsign with a remark 'Without Prejudice, Receipt Only' to indicate that he does not accept the content of the documents.

(2) Legal defences
Legal defences can be further broadly classified into validity of the claim and the claimant, specific terms stated on the
B/L, international cargo regimes and time-limits.

A

Defence based on the validity of the claim and the claimant.

Verify the following points to confirm whether or not the claim is valid.

Do the cargo interests have a proper title to sue?
Have the cargo interests made a claim against the contractual carrier?
When a formal claim is received from cargo interests, it is necessary to ascertain whether they have title to sue against
the carriers. Cargo interests can establish title to sue by showing that they are the lawful holder of the B/L. If the claim
is made by cargo insurers, documentation (for example a Subrogation Receipt) is required to show that they have paid

Very often, cargo interests may arrest the vessel for their alleged claim. In such cases, we (P&I club) will discuss with

the insurance money for a cargo shortage to the assured consignees, and that the insurers have been subrogated tothe cargo interests, and may issue of a letter of guarantee to them in order to avoid an arrest or to secure the release offrom the rights of the consignees. When a claim is received from recovery agents or lawyers, it is necessary for themthe vessel from arrest.
－ 36 －－ 37 －JAPAN P& I CLUBJAPAN P& I CLUBP&I Loss Prevention Bulletinto show that their clients have title to sue, and that they have received a formal authorization to act from their clients.
We will therefore ask for relevant documentation to verify the cargo interests' title to sue in respect of the cargo.
Under English law, the party liable for cargo shortage claims under the B/L is the contractual carrier under the B/
L. As such, it is necessary to determine the identity of the carrier. Under Japanese and English laws, the carrier isdetermined from the B/L. It should be noted that there may be circumstances where a non-contractual carrier under the
B/L may also be liable for a shortage claim where they have a tortious liability to the cargo interests,
Generally, the shipowner (or bareboat charterer) will be the contractual carrier when the B/L is signed 'for the Master'or 'on behalf of the Master' in the signature field of the B/L. When the B/L is signed 'for the Master', it is consideredthat the B/L has been signed on behalf of the Master. Therefore, since the Master is a representative of the shipowner,
the shipowner is considered to be the carrier under the B/L and will be liable for cargo claims in the first instance.

Terms of any incorporated Charter Party (C/P)
Some B/Ls incorporate the terms of a particular Charter Party. Where this is the case,  the date of
the C/P is normally noted on the front of the B/L. It will be a matter of construction, and the law of
the local courts whether the terms of such a C/P will be incorporated into the contract of carriage,in particular law and jurisdiction clause for disputes under the B/L. If a claim is pursued in court
or arbitration, the question of where, and under which jurisdiction, the claim is to be brought anddetermined becomes important.

C

Defence based international cargo regimes
Exemptions under Hague Rules and Hague-Visby Rules

In most B/Ls, there will be a General Paramount clause incorporating one of the international

B

in which these defences are successfully applied to cargo shortage claims. Also, in order to relyon these defences, the carriers must establish that they have before and at the beginning of thevoyage exercised due diligence to make the ship seaworthy, which includes the cargoworthinessof the vessel.

Defence based on specific terms in the B/L

For countries which have not ratified the Hague Rules or Hague-Visby Rules, they are likely to haveenacted legislation of similar content. If so, similar defences may be available under the local laws/

Are there any useful clauses to defend cargo shortage claims on the back side of the B/L?
By way of example, the North American Grain Bill of Lading contains a clause stating that if multiple
Bs/L are issued for the cargo in one hold, any cargo shortage must be allocated equally to each B/L.
Accordingly, if cargo interests' claim for shortage is based on an unequal allocation of the shortage
for all the B/Ls, we can raise the argument that there is an error in the claim amount. For example,
if there is a total cargo shortage of 100 MT for two Bs/L, each for 1,000MT of cargo, the shortage
should be allocated as 50 MT to each B/L, not 100MT to one B/L.
See North American Grain Bill of Lading, 'Clause 5 Each Bill of Lading covering the hold or holds enumerated
herein to bear its proportion of shortage and/or damage, if any incurred.'rules.

Trade allowance
In a number of countries the carrier is exempted from liability for cargo shortage of less than 0.5%of the B/L quantity. Legal precedents for this commercial practice are also available. However, theamount of the trade allowance accepted differs depending on the governing laws, the countries,
the states within a country and the cargoes. In some countries, trade allowance is never accepted.
Caution is required.
While trade allowance is based on commercial practice, if a legal basis is required it can be foundin the carrier exemptions for loss/damage arising from inherent defect, quality or vice of the cargo

Defence using time-limits

Depending on the terms of the C/P, it may be that the B/L is signed by the Master under instructions from the

within one year of the cargo being delivered, cargo interests are likely to take a legal action. In some cases, a legal
action commences without the carrier being informed of the claim, and the first notification of the claim may be asummon received from the court.

4-4 Recovery action against the Charterers and the Shippers

Apart from the 2 year notification of claim time limit if ICA applies, under English law, the time-limit for starting a
recovery action against the charterers is six years from the date of settlement with the cargo interests.
If the carrier under the B/L is the charterers and the charterers have responded to the cargo claim in the first instance, arecovery action may be pursued by charterers against shipowners in accordance with the clauses in C/P.
