8 OCTOBER 2018 • FOGHORN FOGHORNFOCUS: MARINE PROPULSION builds is the Hydrus, a 400-passenger catamaran that can reach a top speed of 29 knots and a service speed of 27 knots. It is one of the earliest passenger vessels to enter service with advanced exhaust aftertreatment to amplify effi- ciency. Hydrus complies with the latest EPAemissions regulations and is one of the lowest emissions ferries currently operating in North America. Following the coast south, Long Beach’s Catalina Express reduced the emissions of its ferry Starship by repow- ering with MTU. Running between San Pedro and Catalina Island, the ferry is now powered by twin 16V 4000 M64 engines, each producing 2,680 hp at 1,800 rpm. Far to the north, the Alaska Marine Highway System repowered the FVF Chenega, leading to a 5-7 percent reduction in fuel consumption due to the vessel’s four new MTU 20V 4000 M73L diesel engines. Between a smoother ride, the elimination of startup smoke, streamlined mainte- nance practices and improved fuel ef- ficiency, fleet operators and passengers agree there are smooth seas ahead for the Chenega. East Coast Not be outdone, the heavily populated U.S. East Coast has its own fair share of passenger vessels. The New York City/New Jersey ferry operator Seastreak added two 600-passenger fast ferries to its fleet. In the summer months, the first ferry, Seastreak Commodore, will operate between New Jersey and Manhattan, and the second ferry will operate between Martha’s Vineyard and Nantucket. A Louisiana shipbuilder is working with designer Incat Crowther on the construction of the new ferries, each of which will be powered by four EPA Tier 3 MTU 12V 4000 M64 engines rated at 1,875 hp at 1,800 rpm and equipped with Rolls-Royce water jets. Engine sales and support is provided by MTU distributor Johnson & Towers. In addition to these two new builds, Seastreak is conducting several strategic repowers of its Highlands, Partners in design This award-winning electric air-cushioned ferry is turning a lot of heads as it cruises at speeds up to 30 knots across Stockholm’s inland waterways. The battery-powered electric motors are connected to twin Volvo Penta IPS drives to deliver a smooth, silent, and enjoyable experience for the crew and passengers. www.volvopenta.us/marinecommercial GOING GREEN 2018-07 Foghorn.indd 1 6/19/2018 10:55:56 AM
