LNG Fueled 9000 TEU Container Ship From KHI
Following in the footsteps or should that be the wake of, Japan’s shipbuilder Kawasaki Heavy Industries (KHI) LNG powered Car Carrier announced in August 2011, KHI is showing a new design of LNG fueled container ship. The design and development are at an advanced stage and Classification Society DNV has granted Approval in Principle.

The container ship, of 9,000 TEU capacity, has an unusual twin island design to maximize available cargo space for loading containers. It has an LOA of 1,010 ft (308 m), beam of 157 ft (48 m) and draft of 47 ft (14.5 m). The ship will be propelled by a single, electronically controlled, slow speed, two stroke, dual fuel main engine and will be offered with exhaust gas recirculation (EGR) which satisfies IMO Tier3 requirements for voyages in North American and European Emission Control Areas (ECAs).
It is the first time that Type B, LNG storage tanks will be used on such a large container ship. Type B rectangular, prismatic, low pressure insulated tanks differ from the more usual cylindrical Type C pressure tanks as they make more efficient use of space. KHI has adopted a special heat insulation technology, the Kawasaki Panel System, to reduce the rate of evaporation of LNG. Type B tanks continuously produce boil-off evaporating LNG and must be used up for propulsion or powering auxiliaries in port, for example supplying power for reefer containers, thereby eliminating the need for cold ironing.
