FERRIES ICE CLASS TANKERS The design of Washington State Ferries’ new 64-car vessels will be based on the M/V Island Home COMBINATION VESSELS W hile orders for new high-speed, passenger-only ferries slowed in the U.S., worldwide demand for larger, more versatile ferries that can carry a mix of passengers, vehicles and cargo rose in 2007. According to an analysis by ASSONAVE, the Italian Shipbuilders and Shiprepairers Association, there were 15 contracts placed in 2007 for ferries in excess of 150 meters, up from just eight the previous year. The top five yards by market share were Aker Yards, with operations in Finland and France, Italy’s Fincantieri, Apuania, and Visentini and Spain’s Barreras. At press time, the M/V Coastal Celebration, last of three 160 m RO/RO ferries built by Germany’s Flensburger, was en route to BC Ferries. The shipyard is also constructing a 150.5m x 23.9m ferry for BC Ferries. The 1,550-dwt ferry will carry a maximum of 600 passengers and will have its keel laid this month. The vessel will be delivered in January 2009. In the high-speed vehicle ferry marMARINE LOG JUNE 2008 YEARBOOK DEMAND UP FOR LARGE ket, the two leading builders, Australia’s Austal and Incat Australia, have made significant deliveries in the past twelve months. Australia’s Austal will deliver the 65m Shinas this month to the Sultanate of Oman. The ferry, which can carry 208 passengers and 56 cars, achieved a speed of 55.9 knots during sea trials last November. A sister vessel, the Hormuz, was recently launched and will be delivered later this year. Classed by DNV under the IMO HSC 2000, the two vessels are each powered by four MTU 20V 1163 TB73L diesel engines that drive KaMeWa 90SII waterjets via Reintjes gears. For its part, Incat Australia delivered the Natchan World, the second of two 112m wave piercing catamarans to Japanese operator Higashi Nihon Ferry. The Natchan World and its sister, the Natchan Rera, can accommodate an impressive 800 passengers and 355 cars, while reaching speeds of 40 knots. The environmentally progressive Natchan World is powered by four MAN 20V 28/33D diesel engines, each rated 9,000 kW at 1,000 rev/min and delivering a low weight when compared to other engines in its class. The latest combustion chamber technology with electronically controlled pump pipe injection system and optimised cylinder pressures, reduces specific fuel consumption to <190g/kWh. At almost a 7% reduction per kWh over the previous generation of medium speed diesel engines this represents a massive saving on annual fuel bills. The vessel is also environmentally compliant with low NOx of <10g/kWh. The ferry is fitted with four of the largest transmissions from ZF Marine GmbH, the ZF 60000 NR2H, each with maximum rated power of 12,387kW. Engine power is converted to propulsion thrust through a new design of waterjet from Wärtsilä. The new LJX waterjet offers, in comparison with other waterjets available today, a 25% reduction in mounting flange diameter, a 10% www.marinelog.com 64 http://www.marinelog.com
