Propulsion Concept

Linde Group to Supply Reliquefaction Equipment for New Fleet of LNG Carriers

Cryostar has won an order from Samsung Heavy Industries totalling over $50m. As part of this order, Cryostar will supply on-board boil-off gas reliquefaction plants for five LNG tankers to be built by 2008. The modern membrane carriers with a cargo capacity of 265,000 cubic meters will be the largest ever built and are destined for LNG trade between Qatar and the U.S.A. The larger the vessel, the more important the boil-off gas management for the LNG. It is stored on board at -163° C, in order to ensure that the maximum cargo is delivered. Cryostar, who provide both the reliquefaction process design and the majority of cryogenic equipment, developed the plant's unique low power consumption technology. The on-board reliquefaction of boil-off gas on LNG tankers with slow speed diesel propulsion makes these carriers highly economic for long distance travel. Thanks to its low CO2 emission, this propulsion concept is also more environmentally friendly than conventional steam propulsion, where the boil-off gas is burned together with heavy fuel oil in boilers.


MAN B&W Diesel and Kawasaki Heavy Industries Sign Order

Kawasaki will build two more MAN B&W Diesel 7S50MC-C two-stroke main engines for Norway. These engines are destined to power two 43,000 dwt chemical tankers built by the Kleven Florø yard for Stolt Nielsen. The engines will be delivered in February and August 2007 respectively. The yard order includes a complete propulsion package from MAN B&W Diesel. This consists of the MAN B&W Diesel 7S50MC-C two-stroke main engines, MAN B&W Diesel VBS1560-ODS controlable pitch propellers


Hybrid Powering for Boxships

A convincing economic argument fuels the liner shipping sector's adoption of unprecedented capacity ratings, with a new level soon to be reached in impending projects for newbuilds in the 9,000-TEU category, and technical work set in train for ships in the 10,000-12,500 TEU category. Experts believe that behemoths of 18,000-TEU could be in service on specific volume trades within a decade, yielding unit operating cost savings in the order of 30-percent relative to the 5,000-TEU size.
