Understand the basic requirements
As from this deadline, ship owners will be required to have on board:
- An approved Ballast Water Management Plan
Existing ships, constructed before 8 September 2017, are required to comply either
- Regulation D-1 - Ballast Water Exchange, until such time regulation D-2 shall be enforced
- Regulation D-2 - Ballast Water Performance, i.e. installation of a Ballast Water System Management
- A Ballast Water Record Book (reg. B-2)
- An International Ballast Water Management Certificate for Ships which are required to be certified, or a Statement of Compliance upon owner's request (according to D-1 or D-2 Standard).
Comply with BWM Regulation D-1 and D-2
To comply with BWM Regulation D-1 and / or D-2, you must develop a Ballast Water Management Plan and submit it for approval.
The Plan must demonstrate how you will achieve:
- D-1 Standard - Ballast Water Exchange
With a goal to achieve volumetric exchange of ballast water of up to 95% of the ballast water capacity, this standard does usually not require modifications to the ship’s existing equipment. Methods used to achieve the goal include: flow-through (pumping to overflow); dilution (ballasts filled through the top allow discharge from the bottom); and sequential (each ballast is emptied and refilled).
- D-2 Standard - Ballast Water Performance
Performance as it involves modifying ship design to install an approved Ballast Water Management System (BWMS). The treatment system is to ensure that discharge water meets defined performance standards, with strict limits on concentrations of viable organisms and microbes. It comprises ballast water treatment equipment, all associated control equipment, monitoring equipment and sampling facilities. The vessel must also carry on board a ballast water record book.
