Biofouling Management Plan and Biofouling Record Book template

A. Format and content of Biofouling Management Plan

Introduction

This section should contain a brief introduction for the ship’s crew, explaining the need for biofouling management, and the importance of accurate record keeping. The plan should state that it is to be available for viewing on request by a port state authority and should be written in the working language of the crew.

Ship particulars

At least the following details should be included:

  1. Ship’s name
  2. Flag
  3. Port of registry
  4. Gross tonnage
  5. Registration number (i.e. IMO number and/or other registration numbers, if applicable)
  6. Regulation length
  7. Beam
  8. Ship type (as classified by Lloyd’s Register)
  9. International call sign and Maritime Mobile Service Identity (MMSI).

Index

A table of contents should be included.

Purpose

The purpose of the plan is to outline measures for control and management of ships’ biofouling in accordance with the 2011 Guidelines for the control and management of ships’ biofouling to minimize the transfer of invasive aquatic species . It provides operational guidance for planning and actions needed for ships’ biofouling management.

Description of anti-fouling systems

The plan should describe the anti-fouling systems in place for different parts of the ship, including:

  • type(s) of anti-fouling coating systems applied
  • details of where anti-fouling systems are and are not applied or installed
  • manufacturer and product names of all coatings or products used in the anti-fouling coating systems
  • anti-fouling system specifications (including dry film thickness for coatings, dosing and frequency for Marine Growth Prevention System (MGPS)) together with the expected effective life, operating conditions required for coatings to be effective, cleaning requirements and any other specifications relevant for paint performance.

Previous reports on the performance of the ship’s anti-fouling systems should be included, if applicable, and the anti-fouling system certificate or statement of compliance or other documentation should also be referenced, as appropriate.

Description of operating profile

The plan should describe the ship’s operating profile that has determined the performance specifications of the ship’s anti-fouling systems and operational practices, including:

  • typical operating speeds
  • periods underway at sea compared with periods berthed, anchored or moored
  • typical operating areas or trading routes
  • planned duration between dry-dockings/slippings.

Description of areas on the ship susceptible to biofouling

The plan should identify the hull areas, niche areas and seawater cooling systems on the ship that are particularly susceptible to biofouling and describe the management actions required for each area. It should describe the actions to be taken if the ship is operating outside the desired operating profile, or if excessive unexpected biofouling is observed, and any other actions that can be taken to minimise accumulation of biofouling on the ship. A diagram of the ship should be included in the plan to identify the location of those areas of the ship that are particularly susceptible to biofouling (including access points in the internal seawater cooling systems). If necessary these should show both side and bottom views of the ship.

Operation and maintenance of the anti-fouling system

This section should contain a detailed description of the operation and maintenance of the anti-fouling system(s) used, including schedule(s) of activities and step-by-step operational procedures.

Timing of operational and maintenance activities

This section should stipulate the schedule of planned inspections, repairs, maintenance and renewal of the anti-fouling systems.

In-water cleaning and maintenance procedures

This section should set out planned maintenance procedures (other than for on-board treatment processes) that need to be completed between dry-docking events to minimise biofouling. This should include routine cleaning or other treatments. Details should be provided on the treatment/cleaning to be conducted, specification of any equipment required, details of the areas to which each specific treatment/

cleaning is to be applied, step-by-step operational procedures where relevant and any other details relevant to the processes (such as chemicals required for treatment and any discharge standards).

Operation of onboard treatment processes

This section should provide specific advice about MGPS fitted, internal seawater cooling systems covered by the system and any not covered, and the associated maintenance and inspection schedule and procedures. This would include information such as when each MGPS is run, for how long and any cleaning/maintenance requirements of the system once use is finished. This section should also include

advice for ship operators on procedures for biofouling management if the MGPS is temporarily out of operation.

Safety procedures for the ship and the crew

Details of specific operational or safety restrictions, including those associated with the management system that affects the ship and/or the crew. Details of specific safety procedures to be followed during ship inspections.

Disposal of biological waste

This section should contain procedures for disposal of biological waste generated by treatment or cleaning processes when the cleaning is conducted by, or under the direct supervision of, the ship owner, master or crew.

Recording requirements

This section should contain details of the types of documentation to be kept to verify the operations and treatments to be recorded in the Biofouling Record Book, as outlined below.

Crew training and familiarisation

This section should contain information on the provision of crew training and familiarisation.

1 Introduction

The guidelines recommend that a Biofouling Record Book be maintained for each ship, in which should be recorded the details of all inspections and biofouling management measures undertaken on the ship.

2 Entries in the Biofouling Record Book

The following information should be recorded in the Biofouling Record Book:

2.1 After each dry-docking:

  1. Date and location that the ship was dry-docked.
  2. Date that ship was re-floated.
  3. Any hull cleaning that was performed while dry-docked, including areas cleaned, method used for cleaning and the location of dry-dock support blocks.
  4. Any anti-fouling coating system, including patch repairs, that was applied while dry-docked. Detail the type of anti-fouling coating system, the area and locations to which it was applied, the coating thickness achieved and any surface preparation work undertaken (e.g. complete removal of underlying anti-fouling coating system or application of new anti-fouling coating system over the top of existing anti-fouling coating system). 
  5. Name, position and signature of the person in charge of the activity for the ship.

2.2 When the hull area, fittings, niches and voids below the waterline have been inspected by divers:

  1. Date and location of ship when dive surveyed and reason for survey.
  2. Area or side of the ship surveyed.
  3. General observations with regard to biofouling (i.e. extent of biofouling and predominant biofouling types, e.g. mussels, barnacles, tubeworms, algae and/or slime).
