PRODUCTSDNV Nod for NLI, WTI Designed LNG Tank Wilhelmsen Technical Solu- tions (WTS) and NLI Solu- tions (NLI) have received Ap- proval in Principal (AiP) from Det Norske Veritas (DNV) on a jointly-developed marine LNG fuel tank design. In development since 2009, in response to growing interest in the use of LNG as marine fuel, the tank is designed to IMO-B standards and is a prismatic, atmospheric and self-supporting LNG steel tank with state of the art cryo- genic insulation. The NLI LNG tank design is well-suited for applications including ship board LNG bunker tanks, tanks for LNG bunker vessels and small LNG carriers. www.wilhelmsen.com / www.nli.no/solutions Cadmium Free Anodes Satisfy 2013 VGP The EPA expects vessel own- ers and operators to comply with regulations regarding dis- charges. VGP requirements for cathodic protection can be met with environmentally-friendly Martyr brand cadmium-free aluminum and magnesium anodes from Canada Metal (Paci? c) Ltd. CMP makes its Martyr brand aluminum and magnesium anodes with no traces of toxic cadmium. Besides helping to protect the marine ecology, Martyr cadmium-free anodes weigh far less than comparable zinc anodes, so vessel owners gain fuel savings as well as peace of mind. Cadmium-free an- odes also offer excellent performance and ef? ciency, lasting longer than their traditional counterparts. www.canmet.com MANs Propulsion Solution for Tuna Vessel PEVASA Group recently ordered a complete propulsion system from MAN Diesel & Turbo for a new tuna vessel. The system is unique in that it comprises a package of three high-ef? ciency products, includ- ing a modern, medium-speed MAN 8L32/44CR engine with common-rail (CR) technology, a Renk RSVL-950 gear unit, and an innovative MAN Alpha VBS1100 CP propeller with Kappel propeller blade designs and rudder bulb. This combination increases the propulsion systems ef? ciency by up to at least 9%, thereby helping to decrease costs, fuel consumption, and exhaust emissions. www.man.eu Promas with Nozzle Improves Ef? ciency and Bollard Pull Promas is a Rolls-Royce propulsion system that integrates the open-water propeller and rudder of a conventional shaftline into a hydrodynamically- ef? cient entity. A tapered hubcap is ? tted to the hub of the propeller and leads the water ? ow on to a bulb which forms part of the spade rudder. Promas installations have given propulsion-ef? ciency improvements up to 6-8 % on newbuildings, and up to 15% on upgrades. The complete AHTS installation can reduce fuel consumption by 15%, with a consequent cut in emissions. It can also improve the bollard pull by typically 5%. www.rolls-royce.com Simrads Professional Autopilot Simrad Yachtings AP60 Professional Autopilot is a dis- tinctive entry-level commercial autopilot. The AP60 completes the Simrad autopilot range by complementing the premium AP70 and award-winning AP80. Simrad autopilots provide the ultimate vessel head- ing control and network integration for every class of com- mercial vessel. Unlike many other entry-level commercial autopilots, the Simrad AP60 includes thruster integration for improved low speed maneuvering. Easy to use, the AP60 includes NoDrift steering, thruster integration and turn patterns such as U-Turn and S-Turn. pro.simrad-yachting.com MacGregor Offshore Winches MacGregor has secured new offshore winch con- tracts from three Chinese shipyards, Fujian South- east, Fuzhou Baima and Guangdong Yuexin Ocean Engineering. The winches are destined for 22 anchor handling tug supply vessels (AHTSVs) under construction for a number of interna- tional owners. The scope of deliveries includes windlasses, mooring winches, capstans, tuggers, anchor handling/tow- ing winches and storage reels; some of the vessels will also be ? tted with MacGregor shark jaws/towing pins. Deliv- eries will begin in August this year and will continue at intervals until March 2014. 42 MNJuly 2013MN July2013 Layout 32-42.indd 426/27/2013 1:06:36 PM
