The California State Lands Commission (SLC) issued notice stating that it has decided to withdraw the proposed regulations entitled “Article 4.8. Biofouling Management to Minimize the Transfer of Nonindigenous Species from Vessels Operating in California Waters”. The SLC expects to republish proposed regulations and commence a new 45-day comment period in the near future.

The Gard P&I Club explains how to manage biofouling risk following a recent case in which authorities ordered a vessel to move outside its territorial waters immediately as they suspected that the vessel’s hull carried organisms that may be harmful to the New Zealand marine environment.

  The State Government of Australia, has taken action to help the shipping and boating industry protect Western Australia’s marine environment from invasive marine pests. Fisheries Minister Ken Baston announced a new risk assessment tool for use by managers of commercial, non-trading, petroleum and commercial fishing vessels coming into WA ports along the coast.   It enables operators to easily assess risk and better manage their vessels, before they leave their last ports of call on their way to WA, by reducing biofouling and reducing the risk of aquatic pests making the journey too. At the launch of Vessel Check in Fremantle today, Mr Baston said the online tool was a welcome initiative to help prevent the introduction of invasive marine species from international and interstate vessel movements. “Vessels are the primary way marine pests are moved to new areas, and the shipping industry and resources sector, together with the Department of Fisheries, identified the need a couple of years ago for a standardised tool to help vessel managers reduce the risk of moving pests into WA in biofouling,” Mr Baston said. “Users of Vessel Check can test different scenarios for their vessel, so they can see how different management actions ...

Integrating sustainable practices into its day-to-day operations, Almouj Marina at The Wave, Muscat in Oman has teamed-up with researchers from Sultan Qaboos University (SQU), Oman's only public university, in a unique project to develop technologically enhanced, nontoxic coatings to be used on boats, submerged structures and industry equipment. Centered on nanotechnology, the study aims to identify environmentally friendly methods that can reduce the impact of biofouling on waterways, marine life, maintenance costs and fuel consumption. Khalil Abujaber, Marina Manager of Almouj Marina, said, "We are delighted to be part of this eco-project and contribute to SQU's research towards the advancement of marine sciences in Oman. The value of the data acquired will potentially have a profound impact, not only on our marine environment, but on the lives of our boaters. As one of Oman's premier marinas, we seek to lead by example in reducing the pollution in our waters to benefit the local community and the boating industry." "This is a unique experiment where state-of-the-art nanotechnology is being applied toward the development of environmentally friendly solutions to biofouling," said Professor Joydeep Dutta, Chair in Nanotechnology in the Water Research Center at SQU. The experiment being conducted in the marina involves ...

A new study of marine organisms that make up the ‘biofouling community’ — tiny creatures that attach themselves to ships’ hulls and rocks in the ocean around the world — shows how they adapt to changing ocean acidification. Reporting in the journal Global Change Biology, the authors examine how these communities may respond to future change. There is overwhelming evidence to suggest the world’s oceans are becoming, and will continue to become more acidic in the future, but there are many questions about how it will affect marine life. The ‘biofouling community’ — consisting of tiny species like sea squirts, hard shell worms and sponges — affects many industries including underwater construction, desalination plants and ship hulls. Removing these organisms (a process called antifouling) is estimated to cost around $22 billion a year globally. For the first experiment of its kind, over 10,000 animals from the highly productive Ria Formosa Lagoon system in Algarve, Portugal were allowed to colonise hard surfaces in six aquarium tanks. In half the tanks, the seawater had the normal acidity for the lagoon (PH 7.9) and the other half were set at an increased acidity of PH 7.7. The conditions represented the IPCC’s prediction for ...

How current antifouling technologies are performing on various ship types BIMCO has launched a survey to find out the real picture on the methods ship owners and operators are using for the treatment of biofouling, and the performance of the various methods on different ships and over varying time periods.Aron Sørensen, Chief Marine Technical Officer at BIMCO, who is leading the study, said: "We believe there is a lack of collective knowledge on biofouling management and treatment practices in the shipping industry. BIMCO would like to build a clearer picture of practice and performance for biofouling management, and how current antifouling technologies are performing on various ship types. We will use and share the outcome to work on the industry's behalf to highlight any issues of concern. Once analysed, the survey result could form the basis for a BIMCO submission to the International Maritime Organization (IMO)."Biofouling means the attachment or association of marine organisms to the wetted portions of a vessel including sea chests, propellers, anchors, and other niche areas.The International Convention on the Control of Harmful Anti-fouling Systems on Ships (AFS Convention) prohibits the use of listed harmful substances in anti-fouling paints used on ships and establishes a mechanism ...
