www.marinelink.com 65 EBDG Alaskan Ferry Repower Elliott Bay Design Group (EBDG) announced the completion of the M/V Columbia (418 ft., 625 pax., 134 vehicles) repower. EBDG provided de- sign services and ongoing owner support services for the ferry’s repower, which was performed by Vigor Marine in Portland, Ore. “The Columbia was designed for the Alaska Marine Highway System (AMHS) by EBDG’s predecessor fi rm, so we’re intimately familiar with the vessel and its systems,” said EBDG Project Manager Matt Williamson. “The main engines were at the end of their useful life and the AMHS opted for replac- ing them, along with replacing or upgrading drive train components and auxiliary systems where it made economic sense. Replacing the main en- gines is a signifi cant undertaking in the life a ves- sel. EBDG’s strong familiarity with the Columbia made us the natural choice as the designer for this repowering project.” www.ebdg.com Hatz New Engine Concept Hatz Diesel, a manufacturer of industrial diesel engines in the power range from 1.5 to 56 kW, presented the concept study of the new 4H50TIC as a marine version at the SMM exhibition in Hamburg. For 20 years Hatz Marine Center of Excellence in Hamburg has developed and pro- duced power generators, pumps and drive units for work and fi shing boats. As a highlight, the concept study of a maritime version of the newly developed 4H50TIC will be presented at the com- pany’s stand. The engine has been manufactured in series production since the beginning of 2014 and is designed primarily for use in construction machinery, as well as for stationary and mobile applications. For use as a marine propulsion en- gine, the engine was converted accordingly. Keel cooling was adopted for the required engine cool- ing and to reduce heat radiation an insulation was installed for the exhaust silencer. Besides this, the 4H50TIC marine includes the same characteris- tics as the base engine. The 55 kW water-cooled two-liter four-cylinder turbo engine is equipped with a BOSCH common rail system with 1800 bar rail pressure. Besides a low power to weight ratio, the engine underlines its ecological characteristics by a low specifi c fuel consumption of just 205 g / kWh at the best point. www.hatz-diesel.com Laborde a Steyr Distributor Laborde Products was chosen as a Steyr Mo- tors distributor, offering sales, service and support throughout Alabama, Arkansas, Indiana, Kansas, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, Oklahoma, Tennessee, Texas and Wis- consin. Laborde will also offer dealer support along the Eastern seaboard of Mexico, from the Texas border to Cancun. Steyr Motors M1 Monoblock engines are known for the lowest weight in class at less than 1.2 kg/ hp and the highest power density, up to 92 hp/ltr. Steyr also offers compact dimensions and low fuel and oil consumption in 2-, 4- and 6-cylinder confi gurations. www.labordeproducts.com Hatz Laborde (Photo: EBDG) EBDG Low Loss Hybrid Energy System Wärtsilä launched its new Low Loss Hy- brid (LLH) innovation at ONS 2014. The Wärtsilä LLH uses different power sources in combination with energy storage devic- es to operate the prime movers closest to their optimum performance. In addition to annual fuel savings of up to 15%, de- pending on the type and confi guration of the engine and mission profi le, the LLH ensures a substantial reduction in exhaust gas emissions, the manufacturer said. The Wärtsilä LLH was earlier this year in- stalled and tested aboard the Platform Sup- ply Vessel Viking Lady. A comprehensive measurement program that monitored transit mode in heavy weather conditions, critical operations, and standby mode confi rmed actual fuel savings of 15%. For this particular vessel, such savings would give an estimated payback time of less than four years. Emission reductions were also sub- stantial, with local emissions in harbor virtually eliminated. www.wartsila.com Wärtsilä’s test facility is equipped to carry out full scale testing of the LLH integrated with Wärtsilä dis- tribution system.
