GUIDELINES FOR APPROVAL OF

BALLAST WATER MANAGEMENT SYSTEMS (G8)

1 INTRODUCTION

General

1.1 These Guidelines for approval of ballast water management systems are aimed

primarily at Administrations, or their designa ted bodies, in order to assess whether ballast

water management systems meet the standard as set out in regulation D

- 2 of the

“International Convention for the Control and Management of Ships’ Ballast Water

and Sediments,” hereafter referred to as the “Con vention”. In addition, this document can be

used as guidance for manufacturers and shipowners on the evaluation procedure that

equipment will undergo and the requirements placed on ballast water management systems.

These Guidelines should be applied in a n objective, consistent and transparent way and their

application should be evaluated periodically by the Organization.

1.2 Articles and regulations referred to in these Guidelines are those contained in

the Convention.

1.3 The Guidelines include general requirements concerning design and construction,

technical procedures for evaluation and the procedure for issuance of the Type Approval

Certificate of the ballast water management system.

1.4 These Guidelines are intended to fit within an overall framew ork for evaluating the

performance of systems that includes the experimental shipboard evaluation of prototype systems

under the provisions of regulation D

- 4, approval of ballast water management systems and

associated systems that comply fully with the re quirements of the Convention, and port State

control sampling for compliance under the provisions of article 9 of the Convention.

1.5 The requirements of regulation D

- 3 stipulate that ballast water management systems used

to comply with the Convention mus t be approved by the Administration, taking into account

these Guidelines. In addition to such ballast water management system approval, as set forth in

regulation A

- 2 and regulation B

- 3, the Convention requires that discharges of ballast water from

ships must meet the regulation D

- 2 performance standard on an on

- going basis. Approval of a

system is intended to screen

- out management systems that would fail to meet the standards

prescribed in regulation D

- 2 of the Convention. Approval of a system, however , does not ensure

that a given system will work on all vessels or in all situations. To satisfy the Convention, a

discharge must comply with the D

- 2 standard throughout the life of the vessel.

1.6 The operation of ballast water management systems should not impair the health and

safety of the ship or personnel, nor should it present any unacceptable harm to the

environment or to public health.

1.7 Ballast water management systems are required to meet the standards of

regulation D

- 2 and the conditions est ablished in regulation D

- 3 of the Convention.MEPC 58/23

ANNEX 4

Page 4

Document7 These Guidelines serve to evaluate the safety, environmental acceptability, practicability and

biological effectiveness of the systems designed to meet these standards and conditions.

The cost effectiveness of type

- approved equipment will be used in determining the need for

revisions of these Guidelines.

1.8 These Guidelines contain recommendations regarding the design, installation,

performance, testing environmental acceptability and approval of ballast wate r

management systems.

1.9 To achieve consistency in its application, the approval procedure requires that a uniform

manner of testing, analysis of samples, and evaluation of results is developed and applied.

These Guidelines should be applied in an objec tive, consistent, and transparent way; and their

suitability should be periodically evaluated and revised as appropriate by the Organization.

New versions of these Guidelines should be duly circulated by the Organization. Due

consideration should be give n to the practicability of the ballast water management systems.

Goal and purpose

1.10 The goal of these Guidelines is to ensure uniform and proper application of the

standards contained in the Convention. As such the Guidelines are to be updated as the state

of knowledge and technology may require.

1.11 The purposes of these Guidelines are to:

.1 define test and performance requirements for the approval of ballast water

management systems;

.2 assist Administrations in determining appropriate design, construction and

operational parameters necessary for the approval of ballast water management

systems;

.3 provide a uniform interpretation and application of the requirements of

regulation D

- 3;

.4 provide guidance to Administrations, equipment manufactu rers and shipowners in

determining the suitability of equipment to meet the requirements of

the Convention and of the environmental acceptability of treated water; and

.5 assure that ballast water management systems approved by Administrations are

capable of achieving the standard of regulation D

- 2 in land

- based and shipboard

evaluations and do not cause unacceptable harm to the vessel, crew, the

environment or public health.

Applicability

1.12 These Guidelines apply to the approval of ballast water mana gement systems in

accordance with the Convention.

1.13 These Guidelines apply to ballast water management systems intended for installation

6 APPROVAL AND CERTIFICATION PROCEDURES

6.1 A BWMS which in every respect fulfils the requirements of these G uidelines may be

approved by the Administration for fitting on board ships. The approval should take the form of

a Type Approval Certificate of BWMS, specifying the main particulars of the apparatus and any

limiting conditions on its usage necessary to en sure its proper performance. Such certificate

should be issued in the format shown in appendix 1. A copy of the Type Approval Certificate

of BWMS should be carried on board ships fitted with such a system at all times.

6.2 A Type Approval Certificate of BWMS should be issued for the specific application for

which the BWMS is approved, e.g., for specific ballast water capacities, flow rates, salinity or

temperature regimes, or other limiting conditions or circumstances as appropriate.

6.3 A Type Approval Certificate of BWMS should be issued by the Administration based on

satisfactory compliance with all the test requirements described in Parts 2, 3 and 4 of the annex.

6.4 An Administration may issue a Type Approval Certificate of BWMS based on separate

PART 1

– SPECIFICATIONS FOR PRE

- TEST EVALUATION OF SYSTEM

DOCUMENTATION

1.1 Adequate documentation should be prep ared and submitted to the Administration as part

of the approval process well in advance of the intended approval testing of a BWMS. Approval

of the submitted documentation should be a pre

- requisite for carrying out independent

approval tests.

General

1 .2 Documentation should be provided by the manufacturer/developer for two primary

purposes: evaluating the readiness of the BWMS for undergoing approval testing, and evaluating

the manufacturer’s proposed test requirements and procedures for the test.

Rea diness evaluation

1.3 The readiness evaluation should examine the design and construction of the BWMS to

determine whether there are any fundamental problems that might constrain the ability of

the BWMS to manage ballast water as proposed by the manufactu rer, or to operate safely,

on board ships. The latter concern should, in addition to basic issues related to the health and

safety of the crew, interactions with the ship’s systems and cargo, and potential adverse

environmental effects, also consider the potential for longer

- term impacts to the safety of the

crew and vessel through effects of the BWMS on corrosion in the ballast system and

other spaces.

1.4 The evaluation should also address the degree, if any, to which the

manufacturer’s/developer’s effo rts during the research and development phase tested the

performance and reliability of the system under operational shipboard conditions and should

include a report of the results of those tests.MEPC 58/23

ANNEX 4

Page 14

Document7 Test proposal evaluation

1.5 Evaluation of the test prop osal should examine all of the manufacturer’s stated

requirements and procedures for installing, calibrating, and operating (including maintenance

requirements) the BWMS during a test. This evaluation should help the test organization to

identify any pote ntial health or environmental safety problems, unusual operating requirements

(labour or materials), and any issues related to the disposal of treatment by

- products or

waste streams.

Documentation

1.6 The documentation to be submitted should include at l east the following:

. l Technical Manual

– The technical description should include:

– product specification;

– process description;

– operational instructions;

– details (including Certificates where appropriate) of the major

components and materials used;

– t echnical installation specifications in accordance with manufacturers’

specific installation criteria;

– system limitations; and

– routine maintenance and trouble

- shooting procedures.

.2 BWMS Drawings

– Diagrammatic drawings of the pumping and piping

arra ngements, electrical/electronic wiring diagrams, which should include

reference to any waste streams and sampling points;

.3 Link to the Ballast Water Management Plan

– Information regarding the

characteristics and arrangements in which the system is to b e installed as well

as the scope of the ships (sizes, types and operation) for which the system is

intended. This information can later form the link between the system and the

ship’s ballast water management plan; and

.4 Environmental and Public Health Impacts

– Potential hazards for the

environment should be identified and documented based on environmental

studies performed to the extent necessary to assure that no harmful effects are

to be expected. In the case of ballast water management systems that make use

of Active Substances or Preparations containing one or more Active

Substances the “Procedure for the approval of ballast water management

systems that make use of Active Substances (G9)”, as revised, should beMEPC 58/23

ANNEX 4

Page 15

Document7 followed. The system should then e nsure that dosage of the Active Substance

and the maximum allowable discharge concentration is kept under the

approved criteria at all times. In the case of ballast water management systems

that do not make use of Active Substances or Preparations, but wh ich could

reasonably be expected to result in changes to the chemical composition of the

treated water such that adverse impacts to receiving waters might occur upon

discharge, the documentation should include results of toxicity tests of treated

water as described in paragraph 5.1.5 of these Guidelines.

1.7 The documentation may include specific information relevant to the test set

- up to be

used for land

- based testing according to these Guidelines. Such information should include

the sampling needed to e nsure proper functioning and any other relevant information needed

to ensure proper evaluation of the efficacy and effects of the equipment. The information

provided should also address general compliance with applicable environment, health and

safety sta ndards during the Type Approval procedure.

to 10 micrometres and less than 50 micrometres in minimum

dimen sion, samples of at least one litre should be collected.

If samples are concentrated for enumeration the samples should be

concentrated using a sieve no greater than 10 micrometres mesh in

diagonal dimension.

.3 For the evaluation of bacteria a sample of at least 500 millilitres

should be taken from the influent and treated water. In the absence

of laboratory facilities on board the toxicogenic test requirements

should be conducted in an appropriately approved laboratory.

However, this may limit the app licability of this test.

.7 The test cycles including invalid and unsuccessful test cycles are to span a trial

period of not less than six months.

.8 The applicant is requested to perform three consecutive test cycles that comply

with regulation D

- 2 and which are valid in accordance with paragraph 2.2.2.5.

Any invalid test cycle does not affect the consecutive sequence.

.9 The source water for test cycles shall be characterized by measurement of salinity,

temperature, particulate organic carbon and tot al suspended solids.

.10 For system operation throughout the trial period, the following information should

also be provided:

.1 documentation of all ballast water operations including volumes and

locations of uptake and discharge, and if heavy weather w as encountered

and where;

.2 the possible reasons for the occurrence of an unsuccessful test cycle, or a

test cycle discharge failing the D

- 2 standard should be investigated and

reported to the Administration;

.3 documentation of scheduled maintenance pe rformed on the system;

.4 documentation of unscheduled maintenance and repair performed on the

system;

.5 documentation of engineering parameters monitored as appropriate to the

specific system; and

Document7 2.3 Land

- based testing

2.3.1 The test set

- up including the ballast water treatment equipment should operate as

described in the provided documentation during at least 5 valid replicate test cycles. Each test

cycle should take place ov er a period of at least 5 days.

2.3.2 A land

- based test cycle should include:

.1 the uptake of ballast water by pumping;

.2 the storage of ballast water for at least 5 days;

.3 treatment of ballast water within the BWMS, except in control tanks; and

. 4 the discharge of ballast water by pumping.

2.3.3 Testing should occur using different water conditions sequentially as provided for in

paragraphs 2.3.17 and 2.3.18.

2.3.4 The BWMS should be tested at its rated capacity or as given in paragraphs 2.3.13

to 2.3.15 for each test cycle. The equipment should function to specifications during this

test.

2.3.5 The analysis of treated water discharge from each test cycle should be used to

determine that the average of discharge samples does not exceed the conc entrations of

regulation D

- 2 of the Convention.

2.3.6 The analysis of treated water discharge from the relevant test cycle(s) should also be used

to evaluate the toxicity of the discharged water for BWMS that make use of Active Substances

and also for tho se BWMS that do not make use of Active Substances or Preparations but which

could reasonably be expected to result in changes to the chemical composition of the treated

water such that adverse impacts to receiving waters might occur upon discharge. Toxici ty tests

of the treated water discharge should be conducted in accordance with paragraphs 5.2.3 to 5.2.7

of the Procedure for approval of ballast water management systems that make use

of Active Substances, as revised (resolution MEPC.169(57)).

Land

- based

testing objectives , limitations and criteria for evaluation

2.3.7 The land

- based testing serves to determine the biological efficacy and environmental

acceptability of the BWMS under consideration for Type Approval. The approval testing aims to

ensure r eplicability and comparability to other treatment equipment.

2.3.8 Any limitations imposed by the ballast water management system on the testing

procedure described here should be duly noted and evaluated by the Administration.

Land

- based set

- up

2.3.9 T he test set

- up for approval tests should be representative of the characteristics and

arrangements of the types of ships in which the equipment is intended to be installed.

The test set

- up should therefore include at least the following:MEPC 58/23

ANNEX 4

Page 19

Document7 .1 the complete BWMS to be tested;

.2 piping and pumping arrangements; and

.3 the storage tank that simulates a ballast tank, constructed such that the water in

the tank should be completely shielded from light.

2.3.10 The control and treated simulated ballast tanks should each include:

.1 a minimum capacity of 200 m 3 ;

.2 normal internal structures, including lightening and drainage holes;

.3 standard industry practices for design, construction and surface coatings for

ships; and

.4 the minimum modifications requi red for structural integrity on land.

2.3.11 The test set

- up should be pressure

- washed with tap water, dried and swept to remove

loose debris, organisms and other matter before starting testing procedures, and between

test cycles.

2.3.12 The test set

- up will include facilities to allow sampling as described in paragraphs 2.3.26

and 2.3.27 and provisions to supply influents to the system, as specified in paragraph 2.3.19

and/or 2.3.20. The installation arrangements should conform in each case with tho se specified

and approved under the procedure outlined in section 7 of the main body to these Guidelines.

Ballast water treatment equipment scaling

2.3.13 In

- line treatment equipment may be downsized for land

- based testing, but only when

the following criteria are taken into account:

.1 equipment with a TRC equal to or smaller than 200 m 3 /h should not be

downscaled;

.2 equipment with a TRC larger than 200 m 3 /h but smaller than 1,000 m 3 /h may

be downscaled to a maximum of 1:5 scale, but may not be smal ler

than 200 m

3 /h; and

.3 equipment with a TRC equal to, or larger than, 1,000 m 3 /h may be downscaled

to a maximum of 1:100 scale, but may not be smaller than 200 m 3 /h.

2.3.14 The manufacturer of the equipment should demonstrate by using mathematical

modelling and/or calculations, that any downscaling will not affect the ultimate functioning

and effectiveness on board a ship of the type and size for which the equipment

will be certified.

2.3.15 In

- tank treatment equipment should be tested on a scale that allows verification of

full

- scale effectiveness. The suitability of the test set

- up should be evaluated by the

manufacturer and approved by the Administration.MEPC 58/23

ANNEX 4

Page 20

Document7 2.3.16 Larger scaling may be applied and lower flow rates used than provided for in 2. 3.13,

if the manufacturer can provide evidence from full

- scale shipboard testing and in accordance

with 2.3.14 that scaling and flow rates will not adversely affect the ability of the results to

predict full

- scale compliance with the standard.

Land

- based test design

– inlet and outlet criteria

2.3.17 For any given set of test cycles (5 replicates is considered a set) a salinity range

should be chosen. Given the salinity, the test water used in the test set up described above

should have dissolved and p articulate content in one of the following combinations:

Salinity

> 32 PSU 3

–32 PSU < 3 PSU

Dissolved Organic

Carbon (DOC) > 1 mg/l > 5 mg/l > 5 mg/l

Particulate

Organic Carbon

(POC) > 1 mg/l > 5 mg/l > 5 mg/l

Total Suspended

Solids (TSS) > 1 mg/l > 50 mg/l > 50 mg/l

2.3.18 At least two sets of tests cycles should be conducted, each with a different salinity range

and associated dissolved and particulate content as prescribed in paragraph 2.3.17. Tests under

adjacent salinity ranges in the abo ve table should be separated by at least 10 PSU 2

.

2.3.19 Test organisms may be either naturally occurring in the test water, or cultured

species that may be added to the test water. The organism concentration should comply with

paragraph 2.3.20 below.

2.3.20 The influent water should include:

.1 test organisms of greater than or equal to 50 micrometres or more in minimum

dimension should be present in a total density of preferably 10 6 but not less

than 10 5 individuals per cubic metre, and should con sist of at least 5 species

from at least 3 different phyla/divisions;

.2 test organisms greater than or equal to 10 micrometres and less

than 50 micrometres in minimum dimension should be present in a total

density of preferably 10 4 but not less than 10 3 individuals per millilitre, and

should consist of at least 5 species from at least 3 different phyla/divisions;

.3 heterotrophic bacteria should be present in a density of at least 10 4 living

bacteria per millilitre; and

2 For example, if one set of test cycles is carried out at >32 PSU and a second set at 3

- 32 PSU, the test cycl e

in the 3

- 32 PSU range needs to be at least 10 PSU less than the lowest salinity used in the test cycle in

the >32 PSU range.MEPC 58/23

ANNEX 4

Page 21

Document7 .4 the variety of organisms in th e test water should be documented according to

the size classes mentioned above regardless if natural organism assemblages or

cultured organisms were used to meet the density and organism variety

requirements.

2.3.21 The following bacteria do not need t o be added to the influent water, but should be

measured at the influent and at the time of discharge:

.1 Coliform;

.2 Enterococcus group;

.3 Vibrio cholerae ; and

.4 Heterotrophic bacteria.

2.3.22 If cultured test organisms are used, then it should be ensured that local applicable

quarantine regulations are taken into account during culturing and discharge.

Land

- based monitoring and sampling

2.3.23 Change of numbers of test organisms by treatment and during storage in the

simulated ballast tank s hould be measured using methods described in Part 4 of the annex,

paragraphs 4.5 to 4.7.

2.3.24 It should be verified that the treatment equipment performs within its specified

parameters, such as power consumption and flow rate, during the test cycle.

2.3.25 Environmental parameters such as pH, temperature, salinity, dissolved oxygen, TSS,

DOC, POC and turbidity (NTU) 3 should be measured at the same time that the samples

described are taken.

2.3.26 Samples during the test should be taken at the fo llowing times and locations:

immediately before the treatment equipment, immediately after the treatment equipment and

upon discharge.

2.3.27 The control and treatment cycles may be run simultaneously or sequentially. Control

samples are to be taken in the same manner as the equipment test as prescribed in

paragraph 2.3.26 and upon influent and discharge. A series of examples are included

in figure 1.

2.3.28 Facilities or arrangements for sampling should be provided to ensure representative

samples of treated and control water can be taken that introduce as little adverse effects as

possible on the organisms.

2.3.29 Samples described in paragraphs 2.3.26 and 2.3.27 should be collected in triplicate

on each occasion.

3 NTU=Nominal Turbidity Unit.MEPC 58/23

ANNEX 4

Page 22

Document7 2.3.30 Separate samples shoul d be collected for:

.1 organisms of greater than or equal to 50 micrometres or more in minimum

dimension;

.2 organisms greater than or equal to 10 micrometres and less

than 50 micrometres in minimum dimension ;

.3 for coliform, enterococcus group, Vi brio cholerae and heterotrophic bacteria;

and

.4 toxicity testing of treated water, from the discharge, for BWMS that make use

of Active Substances and also for those BWMS that do not make use

of Active Substances or Preparations but which could reasonabl y be expected to

result in changes to the chemical composition of the treated water such that

adverse impacts to receiving waters might occur upon discharge.

2.3.31 For the comparison of organisms of greater than or equal to 50 micrometres or more

in mi nimum dimension against the D

- 2 standard, at least 20 litres of influent water

and l cubic metre of treated water, in triplicate respectively, should be collected. If samples

are concentrated for enumeration, the samples should be concentrated using a sie ve no

greater than 50 micrometres mesh in the diagonal dimension.

2.3.32 For the evaluation of organisms greater than or equal to 10 micrometres and less

than 50 micrometres in minimum dimension, at least 1 litre of influent water and at

least 10 litres of treated water should be colle cted. If samples are concentrated

for enumeration, the samples should be concentrated using a sieve no greater

than 10 micrometres mesh in the diagonal dimension.

2.3.33 For the evaluation of bacteria, at least 500 milli litres of influent and treated water

should be collected in sterile bottles.

2.3.34 The samples should be analysed as soon as possible after sampling, and analysed live

within 6 hours or treated in such a way so as to ensure that proper analysis can be performed.

2.3.35 The efficacy of a proposed system should be tested by means of standard scientific

methodology in the form of controlled experimentation, i.e. “experiments”. Specifically, the

effect of the BWMS on organism concentration in ballast wa ter should be tested by

comparing treated ballast water, i.e. “treated groups”, to untreated “control groups”,

such that:

.1 one experiment should consist of a comparison between control water and treated

water. Multiple samples, but at a minimum of thre e, of control and treated water

within a single test cycle should be taken to obtain a good statistical estimate of

the conditions within the water during that experiment. Multiple samples taken

during a single test cycle should not be treated as independ ent measures in the

statistical evaluation of treatment effect, to avoid “pseudo

- replication”.MEPC 58/23

ANNEX 4

Page 23

Document7 2.3.36 If

in any test cycle the average discharge results from the control water is a

concentration less than or equal to 10 times the values in regulation D

- 2.1, the test cycle is

invalid.

2.3.37 Statistical analysis of BWMS performance should consist of t

- tests, or similar statistical

tests, comparing control and treated water. The comparison between control and treated water

will provide a test of unexpe cted mortality in the control water, indicating the effect of an

uncontrolled source of mortality in the testing arrangement.

2.4 Reporting of test results

2.4.1 After approval tests have been completed, a report should be submitted to

the Administration . This report should include information regarding the test design,

methods of analysis and the results of these analyses.

2.4.2 The results of biological efficacy testing of the BWMS should be accepted if during the

land

- based and shipboard testing cond ucted as specified in sections 2.2 and 2.3 of this annex it is

shown that the system has met the standard in regulation D

- 2 in all test cycles as provided in

paragraph 4.7 below.

PART 4

– SAMPLE ANALYSIS METHODS FOR THE DETERMINATION OF

BIOLOGICAL CONSTITUENTS IN BALLAST WATER

Sample processing and analysis

4.1 Samples taken during testing of BWMS are likely to conta in a wide taxonomic diversity

of organisms, varying greatly in size and susceptibilities to damage from sampling and analysis.

4.2 When available, widely accepted standard methods for the collection, handling

(including concentration), storage, and analy sis of samples should be used. These methods

should be clearly cited and described in test plans and reports. This includes methods for

detecting, enumerating, and identifying organisms and for determining viability (as defined in

these Guidelines).

4.3 When standard methods are not available for particular organisms or taxonomic groups,

methods that are developed for use should be described in detail in test plans and reports.

The descriptive documentation should include any experiments needed to valid ate the use of

the methods.

4.4 Given the complexity in samples of natural and treated water, the required rarity of

organisms in treated samples under regulation D

- 2, and the expense and time requirements of

current standard methods, it is likely that se veral new approaches will be developed for the

analyses of the composition, concentration, and viability of organisms in samples of ballast

water. Administrations/Parties are encouraged to share information concerning methods for the

analysis of ballast w ater samples, using existing scientific venues, and papers distributed through

the Organization.

Sample analysis for determining efficacy in meeting the discharge standard

4.5 Sample analysis is meant to determine the species composition and the number of

viable organisms in the sample. Different samples may be taken for determination of

viability and for species composition.MEPC 58/23

ANNEX 4

Page 26

Document7 4.6 Viability of an organism can be determined through live/dead judgement by

appropriate methods including, but not limited to: morphological change

, mobility, staining

using vital dyes or molecular techniques.

4.7 A treatment test cycle should be deemed successful if:

.1 it is valid in accordance with paragraph 2.2.2.5 or 2.3.36 as appropriate;

.2 the average density of organi sms greater than or equal to 50 micrometres in

minimum diameter in the replicate samples is less than 10 viable organisms per

cubic metre;

.3 the average density of organisms less than 50 micrometres and greater than or

equal to 10 micrometres in minimum diameter in the replicate samples is less

than 10 viable organisms per millilitre;

.4 the average density of Vibrio cholerae (serotypes O1 and O139) is less

than 1 cfu per 100 millilitres, or less than 1 cfu per 1 gramme (wet weight)

zooplankton samples;

.5 the average density of E. coli in the replicate samples is less than 250 cfu

per 100 millilitres; and

.6 the average density of intestinal Enterococci in the replicate samples is less

than 100 cfu per 100 millilitres.

4.8 It is recommended that a non

- exhaustive list of standard methods and innovative research

techniques be considered 4

.

Sample analysis for determining eco

- toxicological acceptability of discharge

4.9 Toxicity tests of the treated water discharge should be conducted in accordance with

paragraphs 5.2.3 to 5.2.7 of the Procedure for approval of ballast water management systems that

make use of Active Substances, as revised (resolution MEPC.169(57)).
