Biofouling Management Plan

The Biofouling Management Plan (BFMP) is strongly recommended for all vessels under IMO Resolution MEPC.378(80), adopted in July 2023, which significantly strengthened the previous 2011 voluntary guidelines. While the IMO guidelines are not yet mandatory convention requirements, Australia, New Zealand, and California already enforce biofouling management as a legal requirement, and multiple flag states now expect a BFMP as standard compliance documentation. The IMO agreed at MEPC 83 (April 2025) to develop a legally binding biofouling framework, with mandatory international requirements expected by approximately 2029. Biofouling—the accumulation of aquatic organisms on a vessel’s hull and underwater surfaces—is the primary pathway for invasive marine species to spread between ocean regions. Unmanaged biofouling is also a significant source of hydrodynamic drag, increasing fuel consumption and emissions. For superyachts, which are particularly mobile and frequently cross biogeographic boundaries, a professionally structured BFMP and associated record book are now essential compliance documents.

Who Needs This

A Biofouling Management Plan is strongly recommended for every superyacht under IMO MEPC.378(80), and is already a legal requirement for vessels operating in Australia, New Zealand, and California. Enforcement is most advanced in Australia and New Zealand, which operate the world’s strictest biofouling regimes and conduct hull inspections using the IMO Biofouling Level of Fouling (LOF) assessment scale. Vessels arriving in Australian or New Zealand waters with inadequate documentation, or with hull fouling above the acceptable LOF threshold, may be refused entry, required to undertake at-sea hull cleaning, or directed to dry dock. Vessels trading across the Pacific should consider this package a high-priority compliance requirement. Even in regions where enforcement is still developing, surveyors and flag states are increasingly verifying BFMP documentation, and multiple flag states now expect a BFMP as standard compliance documentation.

What’s Included

Biofouling Management Plan Template

A fully structured Word document covering all required elements of IMO MEPC.378(80): vessel description and anti-fouling system details, biofouling management objectives, proactive and reactive management measures, in-water cleaning procedures, dry-docking and slipping schedule, niche area management, and record-keeping procedures. The template includes guidance on applying the IMO LOF (Level of Fouling) assessment scale and documenting hull condition in the format required by Australian and New Zealand authorities.

Companion Guide

A practical completion guide walking through every section of the BFMP. Explains how to document your current anti-fouling system, how to establish appropriate inspection and cleaning intervals for your operating pattern, how to record niche area treatments, and what Australia’s Department of Agriculture, Fisheries and Forestry (DAFF) specifically looks for in a biofouling inspection.

Quick Reference Card

A laminate-ready reference card summarising the LOF assessment scale (LOF 0-5), the key obligations under MEPC.378(80), and the pre-arrival reporting requirements for Australia and New Zealand. Suitable for bridge and dive team display.

Biofouling Record Book Template

An Excel-format record book tracking all biofouling management activities in the format required for flag state and port state verification: anti-fouling system details and application dates, hull inspection records, in-water cleaning records with fouling condition assessments, dry-docking records, and niche area treatment logs.

Regulatory Compliance

This BFMP is structured to the IMO Resolution MEPC.378(80) framework and meets the documentation standards expected under both the IMO guidelines and national enforcement regimes. It meets the specific documentation requirements of Australian biosecurity law (Biosecurity Act 2015) and New Zealand’s Craft Risk Management Standard (CRMS). It is designed to meet the requirements of all major flag states. The LOF assessment framework in the template and record book aligns directly with the inspection methodology used by Australian DAFF and New Zealand MPI border biosecurity officers.

How to Use

1. Download all files immediately after purchase
2. Read the Companion Guide before completing the BFMP template
3. Insert your vessel particulars, anti-fouling system details, and current hull condition assessment
4. Establish your proactive inspection and cleaning schedule based on your operating pattern
5. Begin recording all biofouling management activities in the Record Book
6. Complete the pre-arrival reporting form before entering Australian or New Zealand waters
7. Keep the BFMP and Record Book available for inspection at all times

Why Choose Our Template

This BFMP was prepared with direct reference to the mandatory requirements of IMO MEPC.378(80), Australian biosecurity enforcement practice, and the documentation standards expected by major flag states. The companion guide explains the LOF scale and the Australian inspection process in practical terms—not regulatory language. The record book format has been designed to satisfy the specific audit trail requirements of both IMO and national biosecurity authorities. As IMO biofouling requirements continue to develop and additional states implement enforcement, the package will be updated and existing customers will receive revisions at no additional cost.
