Eco-friendly paints could prevent ship hull biofouling

Fouling can lead to higher fuel consumption and the spread of alien specie New environmentally friendly bottom paints have been developed in Sweden to prevent biofouling on ships' hulls.Such fouling can lead to higher fuel consumption and the spread of alien species that do not belong in the local marine environment.Researchers at Gothenburg University and Chalmers University of Technology have spent nine years developing environmentally friendly and effective anti-fouling paints through a joint research programme called Marine Paint.According to a statement, the focus has been on a substance called medetomidine, which has proved highly effective against barnacles, which are considered to be the most problematic fouling organism.To tackle other types of fouling as well (such as algae, mussels, sea squirts and moss animals), the researchers have developed a concept for producing optimised combinations of different anti-fouling agents, or biocides.The idea behind these optimised blends is to combine many different biocides that are effective against different fouling organisms and adjust the balance between them to eliminate all types of fouling.To produce the recipes for these optimised blends, the researchers have also developed a model system where they weigh the effect of different biocides on different fouling organisms against their expected environmental ...

First eco-design Suezmax joins AET fleet

New tanker features hull form optimisation and de-rating of main engine power Recognising the ever increasing demand for more fuel efficient and environmentally friendly vessels, leading tanker owner/operator, AET, has taken delivery of the first of four "eco-design" Suezmax tankers. These are the first Suezmax vessels to be owned by the company.Built by Samsung Heavy Industries in Korea, the first 157,000 dwt vessel was delivered and named Eagle San Antonio at a ceremony today, 26 April 2012. The remaining three sister ships will be delivered during the course of this year.AET has made a significant investment in these new "eco-design" vessels to maximise fuel efficiency and to minimise harmful emissions. Innovations include hull form optimisation and de-rating of the main engine power for low load optimisation. The application of energy saving devices include saver fins, a star propeller and rudder bulb which will substantially reduce the amount of fuel used.In addition, the vessel has obtained Lloyd's Register's "Environmental Protection" notation and a Letter of Compliance for a Green Passport. The Energy Efficiency Design Index (EEDI) attained has been verified by Lloyd's Register that it exceeds IMO's requirements. As a result, the vessel has also qualified for the "Green Ship Programme" ...

Ecofriendly ballast water treatment

Uses a compound produced from seawater to help complete the process An environmentally friendly ballast water treatment solution has been developed that actually uses a compound produced from seawater to help complete the process.The SiCure system, developed by Siemens Water Technologies and supplied by Venteville, is an environmentally friendly solution to prevent invasive foreign organisms from entering national waters via ballast water of ships. The development ties in with the Ballast Water Treaty, which will soon be requiring ships to have a system to purify water of alien organisms.The system uses a combination of physical separation by filters and treatment with hypochlorite, which is itself produced from sea water. At higher volumes treatment with hypochlorite is more space and energy efficient than UV light applications. The system works without the addition of chemicals and can process ballast water at a rate of 600 cubic metres per hour.It's not a problem to be taken lightly. Free from natural predators and checks and balances, alien invasive species can wipe out local industries and they are thought to be harming the global economy to the tune of US$1.4 trillion a year, if not far more.Source: The Motorship

FSG bags ”most eco-friendly con-ro ferry”

It will be constructed with space for 540 cars and 940 standard containers German ro-ro builder Flensburger Schiffbau-Gesellschaft (FSG) has won an order from Canada for a 19,500dwt ferry newbuilding which it describes as "the world's most eco-friendly con-ro ship"Tom Todd writes: FSG said it beat international competition to land the order from an unidentified Canadian shipowner. It is the second time the yard has built for Canada: in 2008 it completed the last of three 160m passenger/ro-ros for BC Ferries which were the world's largest double-enders.FSG managing director Peter Sierk said the new job had come "at just the right moment" and that it had taken two years to develop the tailor-made concept. Referring to the financial and economic crisis he added "thanks to a well-filled order book, FSG has ridden out the storm" and stressed the latest order was "extraordinarily important for us".Construction of the "modern, innovative, environmentally-friendly and flexible" ship starts next October and is scheduled to last until the end of 2013. The newbuild will be about 210m long and the yard said the 19,500dwt capacity was "unusually high" for a con-ro vessel. She will also be very flexible with ramps and clear deck heights for ...

Mitsui to Build Two New IMO-Standard Energy Efficient Supramax 66BCs

Developed as low fuel consumption eco-friendly ship Mitsui Engineering & Shipbuilding Co., Ltd. (with president Mr. Yasuhiko Katoh) has agreed with a first class shipowner to build 2 units of "neo Supramax 66BC", 66,000 dwt bulk carriers of next generation newly developed as low fuel consumption eco-friendly ship.Keeping the superior usability of MES best selling 56,000 dwt type handymax bulk carrier which achieved over 170 contracts, this new and larger type bulk carrier is expected to establish a new segment in bulk carrier market. Development of the ship's design was preceded by hearings from various owners and operators and investigations on more than 600 ports all over the world. This ship is designed to have over-Panamax beam (36m) and shallow draft in consideration of prevailing trade patterns and the expansion of Panama Canal in 2014.Despite its larger deadweight and cargo capacity than Mitsui 56, neo Supramax 66BC achieves even less fuel consumption by adopting newly developed hull form and other energy saving equipment.At IMO MEPC62 held from 11th to 15th July, 2011 in London, implementation of new energy efficiency design index (EEDI) and actual restrictions on fuel consumption in line therewith have been adopted. Ocean-going ships to be built now ...

Innovative antibiofouling technologies can make shipping more ecofriendly

Nano structured surfaces that make organisms fall off when the ships move Organisms, such as , sticking to the lower structure of ships are increasing the required propulsive power. It is estimated that ships' fuel consumption could be reduced by up to forty percent by removing those organisms. Erosive systems containing biocides are mainly used for this purpose.However, the use of eco-friendly alternatives such as silicon based fouling release coatings, nearly all enhanced with an oil additive, have increased lately. Researchers at GE Global Research Center in the U.S. have shown that organisms react differently to the various silicone fouling release coatings, and coating type crossed with oil type is very important when it comes to establishing an organism's attachment strength magnitude.However, there is a need for improved eco-friendly alternatives and researchers are working on solutions. For example, scientists at the University of Gothenburg in Sweden have developed what they call a "low emission" approach where avermectins, a class of antibiotics, are included. Only very small amounts are released, since the substances in the coating are tightly associated with the binding matrix agent.The scientists found that 1mg avermectin/gr coating very effectively hindered adult barnacles from colonization, but a similar coating ...
