FERRIES MTU Gas Engine on Car Ferry Over in Germany, the City of Constance has tapped Rolls-Royce Power Systems to begin testing an MTU gas engine on a car ferry. The ferry is expected to begin operations on Lake Constance in 2019—and if all goes according to plan, will become the first inland waterway passenger vessel in Europe to operate on LNG propulsion. The ferry, says Rolls-Royce, will be fitted with two 8-cylinder Series 4000 gas engines from MTU, each delivering 746 kW. The two-year trial covers the propulsion system undergoing continuous service conditions while both partners collect the data.

Scotland’s First LNG Ferry Last month, a milestone took place at the Ferguson Marine Engineering Ltd. shipyard in Glasgow when the 88-tonne LNG tank was delivered for Scotland’s first LNG ferry. The 102 m ro/ro passenger ferry, the MV Glen Sannox, is the first in a pair of two dual fuel ferries being built by the yard for Caledonian Maritime Assets Limited (CMAL). The ferry will be able to operate on both LNG and marine gas oil (MGO). “The Scottish Government, like many governments around the world, has ambitious commitments to cut emissions,

meaning we have to explore greater use of greener options for all future ferry requirements,” said James Anderson, Director of Vessels, CMAL. Wärtsilä will provide the propulsion machinery package for the ferry—including the recently delivered 147 m3 LNG tank. Under its contract, Wärtsilä will supply each of the ships with two 6-cylinder 34DF main engines, two 6-cylinder 20DF auxiliary engines, its Wärtsilä Energopac optimized propulsion and maneuvering system and the Wärtsilä LNGPac storage and supply system. The ferry is expected to go into service during the second half of 2018, with the second to follow a few months later.

BC Ferries’ Fleet Renewal Canada’s BC Ferries is on a mission to renew its fleet. The ferry operator currently has two Spirit Class ferries, the Spirit of British Columbia and the Spirit of Vancouver, lined up to undergo conversion to LNG power at Poland’s Remontowa Shipyard. The Spirit of British Columbia will head to the yard this fall, returning to service Spring 2018, while the Spirit of Vancouver will undergo conversion fall 2018, and return Spring 2019. Meanwhile, on the newbuild front, BC Ferries recently took delivery of the final

ferry in its brand new Salish Class of ferries, the Salish Raven. The 107m Salish ferries are each powered by three Wärtsilä 8L20DF engines, generating speeds of up to 15.5 knots; and can each carry 600 passengers/crew and 145 cars. The class marks BC Ferries’ entrance into the LNG world. BC Ferries also recently awarded a contract to Damen Shipyards Group’s Galati Shipyard for the construction of what it calls two minor vessels. The ferries will carry 300 passengers and crew, and at least 44 vehicles. The 81m ferries will be powered by a hybrid-diesel-electric propulsion package, comprised of battery power, electric propulsion and engines that operate on ultra-low sulfur diesel fuel. The ferries are expected to enter service in 2020.
