ClassNK Annual Report on Port State Control

Foreword
This Annual Report on Port State Control (PSC) summarizes deficiencies identified during PSC
inspections carried out in various countries around the world. This report is prepared with the objective ofbuilding awareness of the present state of PSC and thereby improving future onboard maintenance andinspections as well as Safety Management Systems.
The report consists of the following chapters.
Chapter 1: Status of Implementation and Recent Developments in PSC Worldwide
Chapter 2: Statistical Analysis of Detained Ships Registered with ClassNK
Chapter 3: Statistical Analysis of NK SMC Ships Detained by PSC (ISM Code)
Chapter 4: Statistical Analysis of NK MLC Ships Detained by PSC (MLC, 2006)
Chapter 5: Statistical Data from Tokyo MOU, Paris MoU and USCGPort State Control has been recognized as a very direct and effective means to reduce the number ofsubstandard ships as well as to improve the safety of ships at sea and to prevent marine pollution. The
activity of PSC worldwide has significantly been strengthened along with the increasing number of
amendments to the relevant international Conventions.
Further to the above, in order to carry out the effective implementation of port state responsibilities, many
countries have signed a Memorandum of Understanding (MOU) for regional cooperation among local
PSCs, and have agreed to establish a centralized & digitized database system and/or a harmonizedapproach.
The scope of PSC inspection has been extended from the hardware aspect of the ship to the software
aspect such as onboard maintenance or operational procedures ever since the ISM Code was adopted andapplied to all ships and it is still expanding as more new concepts of regulations have been introduced by
the adoption of NOx Tier III regulation, 2020 global cap of sulphur content in fuel oils, Ship Recycling
Convention (the Hong Kong Convention), IMO DCS (EU MRV), etc.
In line with the above progress of PSC, ClassNK has been working hard and will work harder to increase
the transparency of information related to PSC and to eliminate substandard vessels.

ClassNK Annual Report on Port State Control

Chapter 1
Status of Implementation and Recent Developments
in PSC Worldwide
1.1 Amendments to the relevant conventions
Major amendments to international conventions and to the relevant regulations that came into effectfrom 2019 through 2021 are summarized as below.
1.1.1 Data collection system for fuel oil consumption of ships
Entry into force: 1 March 2018
[Refer to ClassNK Technical Information TEC-1139, 1187, 1198]
Data collection system for fuel oil consumption of ships (IMO DCS) is applied to ships of 5,000
gross tonnage and above, for which the Ship Energy Efficiency Management Plan (SEEMP) is
required to be retained on board. IMO DCS requires the companies to do the following inaccordance with methodology included in the SEEMP Part II.
A) To collect each ship's fuel consumption data and relevant parameters from the calendar year
2019B) To aggregate the collected data, and report to the Administration or RO within three (3) months
after the end of each calendar yearC) In the event of the transfer of a ship from one Administration to another and/or a change fromone Company to another, to aggregate the collected data, and report to the Administration or RO
on the day of completion of the transfer or the change or as close as practical theretoD) To provide Statement of Compliance (SOC) onboard the vessel
Further, EU regulation on monitoring, reporting and verification of carbon dioxide emissions (EUMRV) is also applied to ships of 5,000 gross tonnage and above, which arrive at or depart from ports
under the jurisdiction of an EU member state. EU MRV requires the companies to develop the
Monitoring Plan and submit the Emission Report to the RO accredited by the national accreditationbody in EU, and provide a Document of Compliance (DOC) onboard the vessel.
A ship which has not carried out any EEA-related voyages during a whole reporting period (calendar
year X) will not be required to have a DOC of specific reporting period (year X) on board, whencalling at EEA ports between 30 June of year X+1 and 29 June of year X+2.
Meanwhile, it was reported that the reason for not having DOC might be confirmed from port
authority when calling at ports under the jurisdiction of an EU member state. Therefore, it isrecommended to be prepared to show past voyage records.
（FAQ of EU MRV: https://ec.europa.eu/clima/policies/transport/shipping_en#tab-0-3）
1.1.2 EU Regulation on Ship Recycling
Entry into force: 30 December 2013
[Refer to ClassNK Technical Information TEC-1170, -1185, -1224, -1225]
Development of inventory of hazardous materials (IHM) is required for EU flagged ships and nonEU flagged ships by the following date. In addition, ship owners have to ensure that EU flagged
ships are recycled only at the recycling facilities included in the EU List, which list ship recycling
facilities authorized in accordance with the Regulation.
1

ClassNK Annual Report on Port State Control[Deadline for developing and having an IHM onboard](1) EU flagged new ships: The date of delivery (the building contract on/after 31 December 2018)(2) EU flagged existing ships: 31 December 2020 (If a ship is to be recycled before 31 December
2020, IHM shall be prepared prior to recycling)(3) Non-EU flagged ships: 31 December 2020
For EU flagged ships, two hazardous materials (PFOS and HBCDD) are added to the Hong Kong
Convention. Among them, PFOS is compulsory to EU flagged existing ships (EU flagged new ships
are prohibited to carry PFOS). Therefore, even if an IHM complying with the Hong Kong
Convention is provided onboard the EU flagged existing ship, checking of PFOS is additionallyrequired to comply with the EU regulation.
On the other hand, considering the estimated disruptions that several thousand ships are likely to beunable to comply with the IHM obligations and have the required certification by the deadline on 31
December 2020 due to COVID-19 restrictions, the EC has published a Commission Notice suggesting
EU member States apply a harmonized approach towards enforcement during ship inspections for alimited period of 6 months from 31 December 2020 to 30 June 2021.
When a vessel not carrying a valid IHM and/or accompanying certificate on board calls at a port in an
EU member state after December 31 2020, the shipowner or the master should provide "a service
contract for sampling or a survey (quoted from the Commission Notice)” as evidence that all possible
steps have been taken to obtain an IHM (including a "semi-completed IHM") certification, anddocuments showing why the semi-completed IHM could not be obtained.
（Information on Ship Recycling:https://www.classnk.or.jp/hp/en/activities/statutory/shiprecycle/index.html）
1.1.3 2020 global cap of sulphur content in fuel oils
Entry into force: 1 January 2020
[Refer to ClassNK Technical Information TEC-1192]
In order to reduce emissions of Sulphur Oxides (SOx) and Particulate Matter (PM) from ships, thelimit of the sulphur content of any fuel oil used on board ships was tightened to 0.50% m/m outside
emission control areas (ECAs) from 1 January 2020. In case any equivalent means as long as the
reduction method is evaluated to be equivalent to the required reduction of SOx are not installed
onboard, the loading of non-compliant fuel oil is prohibited except for non-availability of compliant
fuel oil.
1.1.4 Maintenance for lifeboats etc.
Entry into force: 1 January 2020
[Refer to ClassNK Technical Information TEC-1183]
On or after 1 January 2020, thorough examinations, operational tests, overhaul and repair of the
lifeboat etc. are to be conducted by certified personnel of either the manufacturer or an authorized
service provider in accordance with IMO Resolution MSC.402(96). In addition, personnel for thework is to be certified for each manufacturer and type of equipment to be worked on.

1.1.5 Electronic record books
Entry into force: 1 October 2020
[Refer to ClassNK Technical Information TEC-1192]
MARPOL Convention requires that ships are provided with several record books for the purpose ofmanagement of pollution prevention. On and after 1 October 2020, approval of the electronic record
books is needed for these record books in accordance with Guidelines for the use of electronic
record books under MARPOL if the electronic record books are used in spite of paper ones.
1.1.6 Application of Cyber Risk Management
Entry into force: 27 October 2020
[Refer to ClassNK Technical Information TEC-1217]
The USCG expects all companies with U.S. flagged vessels and foreign flagged vessels that call at ports
in the U.S. to ensure that cyber risk management is appropriately addressed in their SMS.
If objective evidence indicating that the foreign flagged vessel that calls at ports in the U.S. failed to
implement its SMS with respect to cyber risk management is identified, the following actions should bedirected by the PSCO:(1) If cyber risk management has not been incorporated into the vessel's SMS by the company's firstannual verification of the DOC after 1 January 2021, a deficiency should be issued with action code
30 - Ship Detained.
(2) When objective evidence indicates that the vessel failed to implement its SMS with respect to cyberrisk management, a deficiency for both an operation and an ISM should be issued with an action code
17 - Rectify Prior to Departure or an action code 30 – Ship Detained depending on its seriousness.

New amendments to conventions are also introduced on the ClassNK Website in the section, ‘IMO
International Convention Calendar’.

ClassNK Annual Report on Port State Control

1.2.2 Port State Control in the United States (USCG)(1) Activity
Although the United States Coast Guard (USCG) is not a member of any MOU, it is an observer at anumber of MOUs, and undertakes effective PSC in cooperation with other MOUs. In the 1970's, theU.S. Coast Guard increased its emphasis on the examination of foreign vessels. Although thisemphasis was primarily driven by requirements to ensure compliance with the then new U.S.
pollution prevention and navigation safety regulations, boarding officers also exercised Port Stateauthority when instances of non-compliance with SOLAS and MARPOL were noted. In 1994, theU.S. introduced risk-management methodologies into the Port State Control program in order toallocate limited inspection resources to where they could do the most good, by identifying those
ships, ship owners, classification societies and Flag Administrations that were most often foundlacking in meeting their international Convention responsibilities. On 1 January 2001, the USCG
implemented an initiative to identify high-quality ships, called QUALSHIP 21, quality shipping forthe 21st century. This program has since proven to be very effective in recognizing well operated andmaintained ships of good quality and continues in use today. Further, on 1 July 2017, in addition to
QUALSHIP 21, the program of E-ZERO (Zero Environmental Deficiencies or Violations) began. EZERO designation has been assigned with exemplary vessels that have consistently adhered toenvironmental compliance.
(2) PSC Safety Targeting Matrix
The USCG uses the Port State Control Safety and Environmental Protection Compliance Targeting
Matrix which enables the Coast Guard to rationally and systematically determine the probable risk
posed by non-U.S. ships calling at U.S. ports. The matrix is used to decide which ships Port State
Control Officers should examine on any given day, in any given port. The numerical score, along withother performance-based factors, determines a ship's priority for examination.
(3) Banning of foreign vessels
All foreign flagged vessels operating in U.S. waters are required to be maintained in compliance with
U.S. regulations, international conventions and other required standards. However, when a vessel has
been repeatedly detained by the USCG (totaling three detentions within a twelve-month period) and it
is determined that failure to effectively implement the SMS onboard may be a contributing factor forthe substandard conditions that led to the detentions, the USCG Headquarters (USCG-HQ) will issue
a Letter of Denial prohibiting the ship from further entering any U.S. port until such time as certain
actions have been taken to rectify the situation. However, even if a vessel has less than threedetentions in twelve months, a Letter of Denial may be issued to any vessel which, in the option of
the USCG;
1. may pose a significant risk to the safety of the vessel, crew or the marine environment; or
2. has a history of accidents, pollution incidents, or serious repair problems which creates reason tobelieve that such a vessel may be unsafe or create a threat to the marine environment; or
3. has discharged oil or other hazardous material in violation of any law of the United States or in amanner or quantities inconsistent with the provisions of any treaty to which the United States is aparty.

ClassNK Annual Report on Port State Control

1.3 Measures adopted by ClassNK
1.3.1 Handling of the Deficiencies Identified by PSC Inspections(1) Cooperative assistance with PSC and treatment of deficiencies
When surveyors of the Society are notified of the detention of a ship classed with ClassNK, theSociety actively cooperates with the reporting PSC in a number of ways. The more direct of thesesteps include the following.
- Surveyors liaise with PSC to ensure that they are called in as soon as appropriate when deficiencies
related to class and/or statutory matters are identified.
- Surveyors liaise with PSC officers to ensure uniformity of interpretation of class and statutory
requirements.
- Surveyors provide PSC officers with background information, extracts from reports pertinent to theinspection, and details of conditions of class and statutory items whenever so requested by the PSC.
- Attending surveyors examine not only the condition of the deficiencies identified by the PSC
officers but also expand the scope of the survey for the general condition of the hull, machinery andequipment, or carry out the general examination to the extent of an annual survey if necessary,carefully considering the seriousness of any deficiencies when they attend ships that have been
subject to an intervention action by the PSC.
(2) Treatment of inspection reports by PSC officers
When a surveyor receives an inspection report from PSC, the report is sent to the ClassNK Head
Office. The report is immediately examined by the experienced staff to identify the causes of the
deficiencies. This examination is carried out for all ships for which such reports are received, and theresults are circulated to all sections concerned, as necessary. The results are also reflected in a
ClassNK PSC database that has been developed for the purpose of providing surveyors with PSC
related information electronically. The results of this examination are also submitted to the Flag State
Administration of the ship, as required. Further, visits may also be made to the management company
or others, when deemed appropriate, to advise them of the relevant deficiencies noted and toencourage them to more proactively improve the routine maintenance of their ships and take othermeasures as necessary to ensure the highest levels of safe and environmentally friendly operation.
In cases where the deficiencies pointed out by the PSC are determined to be related to previous
surveys conducted by surveyors of the Society, those surveys are treated as a non-conforming service,
and appropriate corrective and preventive actions are taken in accordance with the ClassNK quality
system.
1.3.2 Minimizing the number of detained ships in order to reduce substandard ships(1) Special training at several in-house meetingsSpecial training on PSC related issues is conducted at several meetings held regularly for generalmanagers and managers, to ensure that surveyors carry out full and effective surveys with anuncompromising attitude towards ensuring the quality and safety of the ships classed with theSociety.
Special re-training is also carried out under the supervision of the Head Office and regional managers,
as needed, for those surveyors who have conducted any surveys determined to be a non-conforming
service under the quality system of the Society.
(2) Meetings and informal gatherings with management companies(a) Visiting Management Companies
When a ship classed with ClassNK is detained by PSC, if deemed necessary, a senior surveyor or
manager of the Society visits the company managing the ship to discuss what steps can be taken to
improve the routine maintenance of the ships in their fleet, so as to prevent both a recurrence of the
deficiencies noted and the occurrence of similar problems in the future.
8ClassNK Annual Report on Port State Control(b) Meetings and seminars
PSC related issues are regularly discussed at informal gatherings and technical committee meetings
held with management companies. At such times, explanations are given and documents arepresented, with emphasis placed on the importance of proactively ensuring the proper maintenanceof ships and education of crew in order to prevent the detention of ships.
(c) Software
Software “PrimeShip-PSC Intelligence” and Mobile application “ARRIVAL CHECKLIST for
PSC” have been prepared in order to support an improvement of PSC performance and ship
management systems.
i) PrimeShip-PSC Intelligence (http://www.classnk.or.jp/hp/en/activities/portal/pscintelligence.html)
This system provides users with various functions to help improve fleet PSC performance andship management systems.
[Main Functions]- Easy visual checking of trends of typical deficiencies, deficiency items or deficiency categories
at each port or country on world-map with AI technologies- Output a pinpoint checklist based on the PSC's past records of selected ports or countries- Analysis on the trend of deficiencies recorded on managing ships on a real-time basis throughthe managing company’s input of PSC reports- Freely set KPIs and ship groups in order to monitor, measure and evaluate them
- Output a summary report for PSC performance of managing ships- Display requirements of the IMO international convention and local regulations applied on
managing ships in a calendar formatii) ARRIVAL CHECKLIST for PSC (http://www.classnk.or.jp/hp/en/info_service/psc/)
A preparatory checklist mobile app to help minimize the risk of PSC detentions and deficiencies.
[Main Functions]- The items frequently pointed out by PSCO can be checked in each area onboard- Check results can be input in the system along with notes and photos- Check results can be forwarded to companies easily- The statistics and tendency of detentions in major ports can be confirmed- Checklists and statistics are updated automatically as needed(d) Publications
The “ClassNK Annual Report on Port State Control” and a checklist entitled “Good Maintenanceon board Ships”, which can be used by the ship’s crew for quick and easy inspection of a ship
before entering port, are distributed to all registered management companies or others in theClassNK fleet and also posted on NK website as below.
(http://www.classnk.or.jp/hp/en/info_service/psc/)
Twenty-two “ClassNK PSC Bulletin” were released as of June 2021. This bulletin provides timely
information on particularly notable deficiencies pointed out during PSC inspections of NK classed ships
and will be continuously provided to management companies.

1.3.3 Visits to PSC authorities
Designated persons from the ClassNK Head Office as well as local survey offices are assigned to visit theheadquarters or offices of various PSC authorities with the aim of introducing ClassNK and exchanging
views on matters of mutual concern. However, considering the circumstances due to the COVID-19
pandemic, ClassNK refrained from visiting PSC authorities in 2020.

Chapter 2
Statistical Analysis of Detained Ships Registered with ClassNK
2.1 General
The data in this chapter, on ships detained due to deficiencies identified during PSC inspections, isbased on the following sources:(1) Notifications from Port States issued in accordance with IMO Resolution A.1138(31) “Procedurefor Port State Control, and(2) Publications related to detained ships issued by the Tokyo MOU, the Paris MoU, and the USCG.
From January to December 2020, 250 PSC detentions were reported relating to 242 ships classed by
NK. This included cases of detention for reasons not related to class or to NK itself. The total number ofNK-registered ships (500 GT or over) was 8,546 at the end of December 2020. Therefore, detention
ratio (Detentions/Registered number in 2020) of the NK fleet in 2020 was about 2.9%.

2.3 Analysis of Detainable Deficiencies
2.3.1 Detainable Deficiencies per Category
In 2020 a total of 658 detainable deficiencies were reported relating to 250 detentions, i.e., deficiencies
which were serious enough to jeopardise the ship’s seaworthiness, safety of the crew onboard, or topresent a threat of harm to the environment and therefore warranted the detention of the ship. The
deficiencies are categorized as shown in Figure 2.3.1 and categories in this figure are based on those of
the Tokyo MOU. Deficiencies related to Fire safety, Life-saving appliances, and Emergency systems
combined accounted for about one-third of the total in 2020.
