MPI requires information from vessels to be sent 48 hours before entry to New Zealand and the following information must be held on the vessel:


• Intended length of stay and intended places to be visited.


• Whether the vessel has spent any extended periods of a stationary nature in a single location.


• Age of the antifouling coating, including when it was applied and when it expires.


• If the vessel is coming to undergo biofouling cleaning on arrival, any formal arrangement for cleaning or treatment that they have undertaken.


• Measures that have been or will be used to meet the requirements of the standard.


• Whether the operator or person in charge has developed an MPI-approved Craft Risk Management Plan to comply with the required Standard.


New Zealand has also announced introduction of a new biofouling survey that will involve compulsory hull checks. The aim is to build a profile of vessels that are most likely to be contaminated with foreign marine species.


According to Biosecurity New Zealand, part of the country’s Ministry for Primary Industries, the ships randomly selected to take part in the survey will have to undergo a dive inspection and answer questions about biofouling. Beginning in August 2020, the project is to take up to two years and involve up to 40 vessels.


BIMCO RESEARCH, OTHER FACTS AND FIGURES


• There are more than 80,000 large merchant ships in the world.


• A country like Australia, has around 30,000 commercial port calls every year.


• A ship needs a hull cleaning around every two years – depending on where in the world it trades.


• The standard addresses cleaning of the hull as well as niche areas, such as bow thrusters and propeller shafts.


• Commercial diving is comparatively dangerous. In the UK, the fatality rate for commercial divers, according to figures published in 2010 by the Health and Safety Executive (HSE), ranges from 20 to 40 per 100,000. This risk factor is 12.3 to 24.7 times higher than that of the construction sector.


Carl Barnes and Alan Guy of Tyneside-based independent marine coating consultants, Safinah Group recently published a paper in the Royal Institute of Naval Architects publication. In the paper they discuss the development of copper-free antifouling coatings and the challenges faced in bringing new products to the market.


Safinah Group also have analysed underwater hull fouling condition on a sample of 249 ships which drydocked over a four-year period between 2015-2019. The sample included all major ship types covering a range of trading activity.


It was found that nearly every vessel surveyed had some degree of underwater hull hard fouling. On 44% of vessels surveyed, over 10% of the underwater hull surface was covered with hard fouling. Anything more than 10% coverage is deemed to cause an ‘unacceptable’ impact on vessel performance by experts.


On many of the vessels surveyed, fouling levels were even worse; approximately 15% of vessels had between 10-20% of hard fouling coverage on the hull, 10% of vessels had 20-30% of hard fouling coverage and the remaining 10% of vessels had between 40-80% of hard fouling coverage.
