USCG Biofouling Management Plan Requirement

Vessels trading in US territorial water should have a biofouling management plan as from 21 June 2012. This can be either a separate plan or incorporated in the ballast water management plan.

According with 33 CFR 151.2050 (g)(3) ballast water management plans should be amended in order to include fouling and sediment removal procedures. These procedures can be in a separate biofouling management plan. If vessel has already implemented procedures in accordance with MEPC.207(62) then no further action is required.

Altho the above US legislation does not require a biofouling record book it is recommended to maintain a record of activities regarding removal of sediments as recommended in MEPC.207(62).

We recommend to include the following areas in your Biofouling management plan. In every proposed area we have listed potential measures.

Vessels outer hull
*Cleaning and re-coating at dry-dock.
*Cleaning, if fouling indication, by divers during propeller cleaning

Propeller / Rudder
*Every dry docking remove fouling and coating with antifouling

Anchor chain
*Use fire-main system while raising anchor to remove sediments.
*Chain Locker
*Clean chain locker during dry docking. Obtain relevant statement from class.

Seawater intakes and internal seawater cooling systems
*To be cleaned and coated in every dry docking

Ballast Tanks
*Avoid ballast operations in areas were water has high sediment content.
*Initiate inspections and remove sediment in regular intervals.
