The 83rd session of the Marine Environment Protection Committee (MEPC) in April 2025 will focus on developing a legally binding framework to manage ships' biofouling, aiming to prevent the spread of invasive species. This initiative, backed by several countries, seeks mandatory requirements for biofouling control, aligning with the IMO’s environmental goals. The framework will address hull cleaning schedules, antifouling system maintenance, and record-keeping, potentially integrating with existing IMO regulations. However, balancing environmental and economic impacts, and coordinating with national regulations, will be challenging.
The GloFouling Partnerships and TEST Projects, extended until 2025, continue supporting biofouling control efforts. In 2025, the World Maritime Day will focus on ocean sustainability, linking biofouling management to broader environmental goals. IMO's 2025 priorities include decarbonization and ocean sustainability, with biofouling management playing a key role.
In 2023, the IMO introduced updated biofouling guidelines that emphasize antifouling systems, biofouling management plans, and regular inspections to reduce fuel consumption and invasive species transfer. The guidelines also encourage effective record-keeping, performance monitoring, and contingency planning for biofouling issues.
For successful biofouling management, adherence to IMO guidelines is crucial. Implementing these measures will enhance operational efficiency, reduce emissions, and protect marine ecosystems.
