BWM Convention(Recent Decisions of MEPC)

Port-based Mobile Ballast Water Treatment Facilities

Schematic diagram of the BWTBoat concept to serve ships

More Guidance is needed for situations where ballast water is loaded to a ship departing for an international voyage without an intention to discharge the ballast water to a BWTBoat or reception facility

Consideration for Major Conversion

MEPC 65 approved a BWM Circular referring that new installation of ballast water management systems should not be treated as a ‘major conversion’ as defined in regulation A-1.5 of the BWM Convention as BWM Convention does not stipulate clearly whether the new installation of ballast water management systems should be treated as a ‘major conversion’.

1. which changes its ballast water carrying capacity by 15 percent or greater

2. which changes the ship type

3. which, in the opinion of the Administration, is projected to prolong its life by ten years or more

4. which results in modifications to its ballast water system other than component replacement-in-kind. Conversion of a ship to meet the provisions of regulation D-1 shall not be deemed to constitute a major conversion for the purpose of this Annex.

Having considered documents MEPC 64/7/2 and MEPC 64/7/7 providing amendments to the MARPOL Annex IV and BWM G4 guidelines, the Committee rejected further discussion….

1. BWM Convention has not yet entered into force,

2. Grey water is not regulated under MARPOL IV,

3. Detailed technical consideration is needed,

4. There are concerns over the implications,

5. There is a need to address the difficulties,(not allowed to discharge sewage in port ?)(have to use additional tanks for temporary

storage of sewage)

6. Untreated sewage should be prohibited to be transferred to ballast water tanks as operational problems will be expected.

Guidelines for port States control under the BWM Convention

Ballast Water Sampling Guidance approved as BWM/Circ.42

• 2~3 years • without any legal-

binding or PSC detention

• the assessment for sampling and analysis technique

Exception and Exemption of the Convention and associated Guidelines for risk assessment under Reg. A-4 of the BWMC

MEPC 68 considered a proposed amendment to article 2 (application) of theConvention to enable the establishment of “same risk area”

1. domestic voyages – even if distance isvery long and may have differentenvironment between ports, they areexempted from the Convention

2. Ocean going – even if distance is short,they are to comply with the Convention

3. Ships engaged in the short internationalvoyages are required to undertake ballastwater exchanges

* Having noted that ballasting operation at the same location is subject to the‘exception’ and exemption of ballast water management is subject to the riskassessment in accordance with G7, MEPC 68 agreed to develop a guidance onestablishment of “same risk area” by new methodology for Risk Assessmentin short sea shipping

Guidance on entry or re-entry of ships into exclusive operation within waters under the jurisdiction of single Party approved as BWM.2/Circ.52 Rev. 1

How to manage BW in ships operating within national waters

Ships operating pursuant to articles 3.2(b) to (d) that cease to operate exclusively in the relevant waters will lose their exclusion from the Convention, which then fully applies to them on an ongoing basis

A case where a ship intends to operate within waters under the jurisdiction of a single Party again, following should be verified :

Holds a valid IBWM Certificate;Discharges all ballast water, any residual ballast water and all sediments; Has a procedure in its approved BWMP for cleaning its BW tanks

A exempted ship (regulation A-4): performs BWE in accordance with regulation B-4, D-1 and approved BWMP (The requirements of regulation A-4.1.4 should be addressed to the satisfaction of the countries of origin and destination of the ship)

Roadmap for implementation of BWM Convention

Early movers should not be required to replace these systems due to the application of the revisedGuidelines

if maintained and operated correctly, should not be required to replace these systems due tooccasional lack of efficacy for reasons beyond the control of the shipowners and ship’s crew

Early movers should not be penalized (sanctioned, warned, detained or excluded) solely due to anoccasional exceedance of the D-2 standard

Considerations for ship owners

prior to BWMS installation

Type approval certificate for BWMS To install a BWMS on board your ship, it must be 'type approved‘. If the

system uses an active substances, basic and final approval from the IMO need to be obtained before the type approval can be granted.

The capacity of BWMS A BWMS has a "Total capacity rate“. This is utilized as an indicator to show how many

cubic meters of ballast water management system can be processed per hour. You will need to choose a system with a TRC high enough to handle a ship’s ballast capacity and operational pumping rate

The required space for the installation of BWMSSystem footprints range from approximately 0.25m² to 145m² depending on their TRC.

Consequently, you should review the specifications for selected BWMS.

Enough power to operate BWMSConsidering that additional power will be required to operate BWMS, you should check to see if you will need to run another generator when the BWMS is in operation or consider installing an additional generator set or have a spare breaker available in the electrical distribution board to provide power to the BWMS.

Negative effect on the structures and coatings of ballast water tankCorrosion is a potential negative effect that may be brought on by BWMS substances and processes. Therefore, you should consider the corrosion inside of ballast water tank or negative effect on coating additionally.

"Gas Safe" or not (Oil/Chemical/Gas Tanker)In case of a tanker, the BWMS will be installed in the "Gas Dangerous Zone“ and

therefore the BWMS will need to be approved as "Gas Safe“.

Manufacturer’s Quality• Verified activities to adequately support customer’s demand

• The control of their supply chain if the capacity is stretched

Installation Bottle Neck• Manufacturer’s production capacity need to meet the anticipated increase in the

number of orders.

Cost consideration (Installation, Running and Maintenance)The main cost considerations are less power consumption, easy maintenance and installation, running and installation cost (USD 400,000 ~ 830,000 : 1,000m/h)

Implications for crew training regarding the operation of BWMSWhatever BWMS you have adopted, training will be required for operation and maintenance of the system. Training requirements will need to be included in the ballast water management plan required by the Convention

Ballast Water Major Noncompliance surveyed by US EPA

• Failure to monitor• Monitoring values exceed effluent limitation• Failure to record de-ballasting correctly• Used wrong reporting form• BWMP incomplete• Exchange occurred within 200NM of shore• Failed to operated BWMS• Falsification of records

For ship’s stability, the following needs to be confirmed

Detailed weights and centres(LCG and VCG) calculation to adjust the lightship properties should be carried

Surveyor should confirm the deviations and sign on the calculated lightweight data sheets

Inclining test should be carried out and Stability booklet should be re-approved

YESNO

1) The deviation of lightweight exceeds 2% or more of the original approved lightweight or 2tones, whichever is greater, or

2) The deviation of lightship longitudinal centre of gravity exceeds 1% or more of the LBP

Do any one of two items listed above apply to your vessel?

Inclining test may be exempted. Re-approval of Stability booklet may be exempted
