Good marine coatings are vital for the maintenance of safe and efficient hull structures Programme will develop appropriate, qualified, expertise in a cost effective and convenient mannerGood marine coatings are vital for the maintenance of safe and efficient hull structures and surfaces.The International Maritime Organisation (IMO) and the International Association of Classification Societies (IACS) require compliance with coatings standards. Inspections under the IMO's Performance Standards for Protective Coatings (PSPC) and IACS' UI SC223 must be carried out by qualified coatings inspectors certified to National Association of Corrosion Engineers (NACE) Coating Inspector Level 2, The Norwegian Professional Council for Education and Certification of Inspectors for Surface Treatment (FROSIO) Inspector Level III or equivalents.To help meet demand for qualified inspectors, Lloyd's Register has developed a new series of online, marine coatings training courses. Coatings and Corrosion Control with the use of Protective Coatings, is an internationally accredited series of coatings-inspection courses."Students will be able to earn either certificates or diplomas, depending on the level they study, in coatings and corrosion control. The qualification achieved by taking the course on Performance Standards for Protective Coatings is equivalent to the NACE and FROSIO qualifications required by IMO and IACS," said Andrew Williamson, Lloyd's Register's ...

Designed by Mitsubishi Heavy Industries A new bulk cargo carrier ship, designed by Japan-based industrial machinery manu- facturer Mitsubishi Heavy Industries (MHI), uses the company's Mitsubishi air lubrication system (MALS) and an efficient hull form and enhanced propulsion system to reduce carbon dioxide (CO2) emissions by 25%.As the first commercial application of the new design, MHI will provide its conceptual design and green technologies for three grain carriers to be built for Archer Daniels Midland Company (ADMC), of the US, the company announced."The new bulk carrier design adopts the company's proprietary MALS, which reduces frictional resistance between the vessel hull and seawater by using air bubbles produced by blowers at the bottom of the vessel, along with a high-efficiency hull form and an enhanced propulsion system to enable reduc- tions in CO2 emissions by about 25%, compared with conventional bulk carriers.Bow Shape The three grain carriers will also feature a newly designed bow shape that will reduce wave-making resist- ances. For propulsion, the ship adopts a system to effec- tively convert the main engine power into propulsion power by positioning fins forward of the propellers and placing particular grooves in the propeller boss cap, the com- pany explains.The three grain ...

Rapid Empirical Innovation technology US naval architecture and research company M Ship Co says that its REI (rapid empirical innovation) technology allows it to take hull testing away from the towing tank and test scale ship models at sea.The company says that its REI approach allows models to be towed in real-life weather conditions by a self-powered FLOWT (fast, low-cost, open-water testing) platform. Among other claimed advantages, this is said to save designers, naval architects and builders 50%-80% of the cost of using a conventional towing tank, without sacrificing accuracy or waiting for tank access."The REI programme certainly is an unconventional approach to conventional tank testing," said M Ship Co executive director and co-founder Bill Burns, describing the FLOWT platform's 6m pontooned hull, which employs knife-edged hulls, multiple computer work stations and various adaptable structures, "but the implications of it are of far-reaching importance to the people who shape our industry."Burns explained that two different hull models can be evaluated in tandem, providing direct hull-to-hull comparisons. After the hulls are fabricated they are outfitted with identical high frequency accelerometers that provide comprehensive motion and acceleration comparisons. The models are then tested on the FLOWT platform, providing real-time force, trim and ...

The hull was newly coated with Ecospeed, a glass flake vinyl ester resin underwater hull coating When British Antarctic Survey's RRS (Royal Research Ship) Ernest Shackleton​ was drydocked recently in Denmark, the superintendent, engineers and paint specialists there to check the condition of the hull paint were amazed.After two seasons of battering its way through ice up to 2.5 meters thick with a high content of gravel and volcanic lava adding to its abrasiveness, the hull coating was virtually intact and undamaged.This was in strong contrast to the Shackleton's previous drydocking, when almost the entire hull, bearing a conventional ice-going underwater hull coating, was practically stripped to bare, unprotected steel.The difference lay in the fact that when the Shackleton left drydock in 2009, the hull was newly coated with Ecospeed, a glass flake vinyl ester resin underwater hull coating proven to have extraordinary anti-corrosion protective strength and flexibility. Even though Ecospeed is not intended specifically for ice-going ships and icebreakers, it consistently outperforms the specialized ice-going ship bottom paints.The success of the new underwater hull coating on the Shackleton, whose hull can genuinely be said to undergo the harshest of conditions of just about any vessel afloat, is a story ...

After two seasons of breaking ice up to 2.5m thick the hull coating was intact Belgian company Ecospeed reports that when British Antarctic Survey's RRS Ernest Shackleton was drydocked recently in Denmark, checks on the condition of the hull paint showed it to be virtually intact.After two seasons of breaking ice up to 2.5m thick with a high content of gravel and volcanic lava adding to its abrasiveness, the hull coating was almost undamaged. This, says Ecospeed, was in contrast to the ship's previous drydocking, when almost the entire hull, bearing a conventional ice-going underwater hull coating, was practically stripped to bare, unprotected steel.During Ernest Shackleton's 2009 drydocking, the hull was newly coated with Ecospeed's glass flake vinyl ester resin underwater hull coating, which the company claims is proven to have extraordinary anti-corrosion protective strength and flexibility.Even though Ecospeed is not intended specifically for ice-going ships and icebreakers, the maker says that it consistently outperforms specialised ice-going ship bottom paints.Source: The Motorship

Having a large hole ripped in its hull The Darwin Harbour Master is investigating an incident where a pilot boat crashed into fuel tanker and had a large hole ripped in its hull.On thursday afternoon the Darwin Port Corporation pilot boat had the large gash on its ports side repaired at Cullen Bay Slipway.Darwin Port Corporation spokeswoman Melissa Reiter said the pilot boat collided with the ship's stern on Tuesday afternoon.Ms Reiter said the large hole was above the water line so the boat managed to make it to port under its own steam. "There was a small risk that it would sink," Ms Reiter said.The pilot boat was chaperoning the fuel tanker Cyprus Galaxy into the harbour when the incident happened.Ms Reiter said the pilot boat was travelling beside the ship at high-speed when it crashed.Source: NT News

Government asserts Louisiana company misrepresented hull strength of converted vessels The United States has filed suit in U.S. District Court in Washington, D.C., against Bollinger Shipyards Inc., Bollinger Shipyards Lockport LLC and Halter Bollinger Joint Venture LLC, the Justice Department announced. The suit alleges that Bollinger, which is headquartered in Lockport, La., made material false statements to the Coast Guard under the Deepwater Program.The government's complaint alleges that Bollinger proposed to convert existing 110-Ft Patrol Boats (WPBs) into 123-Ft WPBs by extending the hulls 13 feet and making additional improvements. As a result of Bollinger's misrepresentations about the hull strength of the converted vessels, the Coast Guard awarded a contract to convert eight Coast Guard 110 foot cutters to 123 foot cutters. The first converted cutter, the Matagorda, suffered hull failure when put into service.An investigation by the Coast Guard and the prime contractor, Integrated Coast Guard Systems, concluded that the calculation of hull strength reported by Bollinger to the Coast Guard prior to the conversion was false. Efforts to repair the Matagorda and the other converted vessels were unsuccessful. The cutters are unseaworthy and have been taken out of service."Companies which make false statements to win Coast Guard contracts ...
