中文 (征集中)


Towards the end of 2007 the first of three new Coastal-class double-enders left Flensburger Schiffbau-Gesellschaft for British Columbia in Canada. The vessel features a diesel-electric propulsion. Four eight-cylinder medium-speed diesel engines are located in two separate engine rooms. Each engine is connected to a 4800kVA three-phase synchronous alternator. Together, these generators provide all onboard electrical power and are installed on one common bedplate, which is resiliently mounted to the hull structure. One 11,000kW electric propusion motor is located at each end of the hull, with the drive to each CP propeller taken through a vertically offset reduction gearbox. The motors run at constant revolutions (140 rpm) and are run up to nominal speed by means of a soft starter unit. In transit mode only the aft propeller pushes the ship ahead and the forward propeller is feathered, with all four propeller blades at a pitch angle of around 90deg. A speed of 18 knots was sought with just two gensets running and also supplying power for hotel load and ship’s services. COASTAL RENAISSANCE is fitted with two – one located at each end – electro-hydraulic ram type steering gears and two twist-flow full spade rudders. Cargo access equipment has been supplied by MacGREGOR and comprises two pairs of parallel swinging doors on the main vehicle deck and movable railing on the upper vehicle deck. The two vehicle decks offer a total of 2020 lane metres. The lower deck has a free height of 4.75m and can carry both commercial vehicles such as tractor-trailers, busses and up to 185 North American-sized private cars. The upper vehicle deck has a free height of 2.90m, allowing for the transport of smaller lorries and an additional 185 cars. The vessel features a number of passenger lounges, a snack bar, two children’s play areas, two wheeelhouse and crew spaces. In addition, there are open deck spaces on each side of the ship where embarkation points, with a total of four stations for MES equipment and two fast rescue boats, are fitted.
