What is part of a biofouling management plan?

• A. Records of ballast water management practices
• B. Biofouling Record book including underwater inspections, drydock and cleaning reports
• C. Ballast water discharge schedules
• D. Crew vaccination records

Answer: (B)

A key part of a biofouling management plan is keeping a Biofouling Record Book that includes underwater inspections, drydock findings, and cleaning reports. This documentation provides a verifiable history of hull condition and the actions taken to manage fouling over time. Underwater inspections capture any organisms attached to the hull in the ship’s operating environment, drydocking allows a thorough check of the hull and appendages, and cleaning reports record the removal of fouling and any subsequent reapplication of coatings. Together, these records demonstrate that the plan is being implemented, help planners decide when and how to intervene again, and support audits or inspections from authorities.

Other options relate to ballast water management or crew health, not biofouling control. Ballast water records or discharge schedules address the transport of living organisms via ballast water, while vaccination records concern crew health, not hull fouling.
