Managing biofouling the key to reducing the spread of marine pests

The risk of the petroleum production and exploration industry spreading marine pests is highest when vessels, immersible equipment and infrastructure:

  • are heavily biofouled and organisms such as mussels, oysters, seaweeds and seasquirts are visible
  • are moved to a new area after spending long periods either stationary or at low speeds (including undergoing dockside upgrades)
  • have areas without antifouling coating or the coating is inappropriate for vessel use, aged or worn.

You can reduce the risk by incorporating practices that minimise the build up of biofouling into your routine cleaning and maintenance programs.

To assist you, the document 'National biofouling management guidance for the petroleum production and exploration industryPDF Icon PDF [1.83mb] provides practical recommendations for operators on managing biofouling on petroleum related vessels, equipment and infrastructure.

These recommendations have been developed in conjunction with the petroleum production and exploration industry and apply to the following vessel types:

  • offshore support vessels including utility support vessels, platform supply vessels and anchor handling tug supply vessels
  • mobile offshore drilling units including jack-up units, drilling barges and semi-submersible ships
  • crew transfer vessels
  • diving support vessels
  • accommodation vessels
  • seismic survey vessels
  • landing craft
  • pipelay ships and barges
  • floating production, storage and offloading vessels (FPSO) and floating storage and offloading vessels (FSO).

Operators of oil tankers and gas carriers should refer to the 'National biofouling management guidelines for commercial vessels' PDF Icon PDF [880kb] for guidance on managing biofouling.

Operators of heavy lift vessels and dredges (including rock dumping ships) should refer to the 'National biofouling management guidance for non-trading vesselsPDF Icon PDF [1.34mb] for further information on managing biofouling.

The 'National biofouling management guidance for the petroleum production and exploration industry' also inlcudes information on biofouling management of submersible equipment and infrastructure.
