IMO’s MEPC 72 discussed key environmental issues for global shipping industry on 9-13 April. While global attention was focused on the adoption of initial strategy for the GHG emissions reduction from ships, key themes also included the 2020 sulphur limit, the BWM Convention, HFO use in Arctic, marine litter and biofouling.

From 15 May, all commercial and recreational vessel operators will have to show they have managed biofouling on their vessels before they enter New Zealand waters. In view of this, NZ's Ministry for Primary Industries (MPI) has released guidance on how international vessels can comply with strict new biofouling rules.

Experts from ballast water testing facilities worldwide gathered at IMarEST headquarters in London, on 1-2 February, to discuss the science behind BWM. The meeting was part of the Global TestNet, a forum of organizations involved in standardization and openness of testing for the certification of BWMS.

In an interview with GREEN4SEA, Paul Hallett, manager of the Biosecurity and Environment Group at MPI New Zealand, highlighted current challenges of biofouling, emphasizing on Craft Risk Management Standard for Biofouling, the world’s first such standard at a national scale, entering into force in May 2018.

A team of chemistry researchers from the University of Sydney Nano Institute has created nanostructured surface coatings that have anti-fouling properties without using any toxic components. The new coating uses ‘nanowrinkles’ which are inspired by the carnivorous Nepenthespitcher plant.

The introduction of invasive aquatic species as a result from international shipping has been identified as a significant threat to the world’s oceans and research suggests that 70-80% of introductions occur through biofouling. Madlene Wangrau of UK P&I Club, discusses how shippers could reduce biofouling risk.

New Zealand’s Craft Risk Management Standard requires all vessels arriving shall have a clean hull or adhere to biofouling management best practices. As only few months are left for compliance, the country’s Ministry for Primary Industries encourages operators to contact staff to discuss compliance options for their vessels.

The California State Lands Commission issued a letter to ship agents that might call in California ports, addressing the implementation of biofouling management requirements and reminding of existing reporting requirements.

The BWM treaty entered into force in September 2017. This landmark step was recognized at the latest meeting of the Inter-agency Liaison Group on Invasive Alien Species, which held its 8th session in Brussels, Belgium, 22-23 November.

DNV GL focuses on biofouling, which sees an increasing interest from the industry, as it can be a significant risk for marine environment. While there are no immediate proposals for regulation on the table at the IMO, new regulations are in place or developing in various countries.
