OCTOBER 2017 • FOGHORN 19 FOGHORNFOCUS: MARINE PROPULSION figuration that allows for an increase- -or decrease--in capacity, easily, as required and provides full redundan- cy; and this also allows for customiza- tion in any marine environment. In addition, the battery is connected to an online cloud where data is monitored, thereby enabling the optimization of its operation. The battery storage system is designed to be an adaptable power source, which can be tailored to suit the needs of the vessel operation. It is a ver- tically integrated system. Using cutting-edge design and tech- nology, the performance of the electric ferry is amplified by two propulsion pods from Volvo Penta. Volvo Penta was “happy to par- ticipate” in the BB Green project, as the engineer manufacturer was able to test the viability of fully electric drivelines. The company supplied its state-of-the art pod propulsion technology and Electronic Vessel Control (EVC) System to support the prototype vessel. The pods and EVC system are connected to the electric motors and provide both performance data and practical knowledge of how the fully electric passenger ferry can operate “We are encouraged by the rec- ognition that the BB Green vessel has received,” says Johan Wästeräng, head of Volvo Penta’s marine product management. “Our current focus is to validate the customer benefits that existing and future technologies provide, which is why we see the value in participating in projects like BB Green.” “We see hybrid technology as a step forward in the marine industry, and we are continually looking at new ways in which we can provide new innovative solutions,” Wästeräng added. “To be part of a project that has won a sought- after international accolade shows the investment we are making for the future of transport.” The Swedish operator, Green City Ferries, has a philosophy of producing fast, electronically-driven, quiet vessels with zero emissions to provide envi- ronmentally-friendly transport. The company is dedicated to preserving marine eco-systems and enhancing air quality for passengers. “BB Green is not only the electric ferry of the year but also represents the future – and I think we should all be looking to see how we can make trans- portation better for the future,” said Hans Thornell, chief executive officer of Green City Ferries. n rolls-royce.com KA_steel_1_2_112014 Improved efficiency The new steel series Kamewa waterjets provide improved efficiency over a wider speed range and are available in powers from 450kW to over 30,000kW. The stainless steel mixed flow pump is now even more efficient. A new bucket design improves steering and reversing. The new steel series waterjets are based on a modular platform supplied with steel, aluminium or FRP intake ducts and they are also 15 per cent lighter. modular platform supplied with steel, aluminium Trusted to deliver excellence LEARN MORE For more information, go to http://www.volvopenta.com/marinecommercial/en-en/ news/2017/june/bb-green-electric-commuter-ferry-awarded-electric-and-hybrid-pro.html
