BIMCO AND ICS PROMOTE NEW HULL CLEANING STANDARD

BIMCO AND ICS PROMOTE NEW HULL CLEANING STANDARD

Thursday, February 4, 2021 

Cleaning a ship’s submerged parts from barnacles and other growths, while the ship is in the water, can transfer invasive species to local marine environments unless it is properly cleaned and the debris is captured, so to combat this problem, and to provide clarity and quality assurance to shipowners, ports and government authorities, BIMCO and the International Chamber of Shipping (ICS) have published the first industry standard on in-water cleaning of ships.

David Loosley, BIMCO secretary general, said: “This standard will help protect the environment in the port. Not only that, it will also help every organisation that is part of this process by raising the minimum standard of cleaning several notches higher and ensure that the end result is both a clean ship, and safe working practice.”

A number of countries and regions have put biofouling management high on the agenda, with regional and national regulation on the drawing board or already in place. This includes the USA, Australia, the Baltic Sea region, New Zealand, Hawaii and California.

John Stawpert, Manager (Environment and Trade), ICS said: “This new industry standard establishes a benchmark for safe and environmentally sound underwater hull cleaning, an issue that is of increasing concern to the international community. We hope that this first step by industry bodies will allow cleaning companies to demonstrate that their products protect the marine environment, and that shipowners can be confident that their ships are cleaned to a safe and effective level around the world. With these industry standards port authorities can also have confidence that underwater hull cleaning can be completed with minimal risk to the environment by independently approved cleaning companies working to proven high standards.”

According to the industry standard, at least 90% of the macro fouling must be captured by the cleaning company, and effluent water coming back into the sea will have removed organisms and materials down to a microscopic size (0.000001m).

For BIMCO and the partners involved, the next step is to implement the standard on a small scale and several shipping companies have already signed up to participate.

“It is one of the typical, long term, unglamorous, behind the scenes efforts that the industry undertakes, which will hopefully have a wide-reaching positive impact on the marine environment and the industry,” said Loosley. 

The industry will now work to implement the standards with a number of stakeholders, including paint manufacturers, in-water cleaning companies, shipowners, ports, and classification societies. These stakeholders will then update their procedures, which will lead to successful cleanings, and ultimately – BIMCO and ICS hopes - to a general wide-spread acceptance of the standard and associated certification and more ports allowing in-water cleaning.

The standard details planning, documentation and assessment of the operation, as well as the actual cleaning, the management of the effluent – the water involved in cleaning – including the capture of particles, before it is released back into the sea.

The standard also includes:

  • Criteria for the cleanliness of water pumped back to sea
  • Methods to help shipowners act before the biofouling growth and coverage become severe
  • An approval procedure for cleaning companies
  • Minimum reporting requirements
  • Minimum requirements for an inspection, service and cleaning reports

The standard was developed by a coalition of companies and organisations including, along with BIMCO and ICS:

Akzo Nobel, C-Leanship, CMA Ships, DG Diving Group, Fleet Cleaner, Hapag-Lloyd, Hempel, HullWiper, International Association of Classification Societies, Minerva Shipping, Portland Port (UK), Port of Rotterdam and PPG Coatings.
