The Australian Maritime Safety Authority has issued Marine Notice 19/2013 regarding Biofouling and In-water Cleaning

The stowaways can arrive either as biofouling or via water in the ballast tanks An international team of researchers led by PhD candidate Chris Ware from the University of Tromsø in Norway has for the first time been able to calculate the risk of new species establishing themselves in Arctic waters. Specifically, the researchers have investigated the maritime traffic to Svalbard. Chris Ware explains:The survey shows that up to one third of the 155 ships that entered the ports of Svalbard during 2011 came from ports that will in the future have an environmental match with Svalbard, thereby increasing the risk that harmful species, which may be brought in as stowaways on ships, will be able to establish themselves.The stowaways can arrive either as biofouling on the outside of the ships or via water in the ballast tanks.In 2011 ships that called at Svalbard emptied their ballast tanks 31 times, producing a total volume of 653,000 cubic meters, equivalent to more than 261 Olympic-size swimming pools. Considering each cubic metre of ballast water may contain hundreds of thousands of organisms, billions of organisms can be introduced by ships every year. Slightly more than half of the vessels had replaced the ...

Guidance on Shipboard Operational Matters

65th session, from 13 to 17 May 2013 The Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) meets for its 65th session from 13 to 17 May 2013, at IMO Headquarters in London.Items on the busy agenda include the implementation of energy-efficiency regulations and the ballast water management and ship-recycling treaties.Furtherguidelines on energy-efficiency measures for ships to be consideredThe MEPC is expected to continue its work on further developing technical and operational measures relating to energy-efficiency measures for ships, following the entry into force, on January 2013, of the new chapter 4 of MARPOL Annex VI, which includes requirements mandating the Energy Efficiency Design Index (EEDI), for new ships, and the Ship Energy Efficiency Management Plan (SEEMP), for all ships.The Committee will review draft guidance developed by a correspondence group, including:draft guidelines for determining minimum propulsion power to maintain the manoeuvrability of ships in adverse conditions;draft guidance on treatment of innovative energy-efficiency technologies for calculation and verification of the attained EEDI; anddraft guidelines for the calculation of the coefficient fw for decrease in ship speed in a representative sea condition.Resolution on technical cooperation for energy efficiency measures to be discussedThe MEPC is expected to further consider the ...
