Vessel biofouling represents a significant pathway for the introduction of non-indigenous species into New Zealand’s marine ecosystems and subsequent spread. To manage the risks associated with vessel biofouling, the Ministry for Primary Industries (MPI) issued the Craft Risk Management Standard (CRMS-BIOFOUL) for Biofouling on Vessels Arriving to New Zealand, which came into force on 15th May 2018.
MPI and internationally commissioned research has shown that vessel biofouling is not evenly distributed across the surface of a hull. A higher biomass of organisms tends to accumulate in areas that have no antifouling protection, are protected from a constant or uniform water flow, or are in areas susceptible to antifouling coating wear or damage. On large vessels (i.e., > 40 m), these “niche areas” may include internal seawater systems, such as cavities (e.g., sea chests, box coolers), internal pipework and enclosures (including crossovers and cofferdams) and associated seawater systems (e.g., air conditioning, engine cooling, firefighting systems).
Preventive biofouling management provides an opportunity to minimise the likelihood of entry and spread of non-indigenous species. While operational and economic benefits of preventive external hull management are well documented, benefits associated with preventive biofouling management of internal seawater systems are less well understood.
