Energy Navigator
Kawasaki Shipbuilding Corporation (great ship builder of cargo ships and sometimes yachts) delivered the 147,000m3 LNG Carrier, ENERGY NAVIGATOR (HN: 1600) to the co-owner, Tokyo LNG Tanker Co., Ltd. and Mitsui OSK Line on June 30, 2008. The LNG carrier is the ninth of the 147,000m3 class, a design developed by Kawasaki, and highly evaluated by owners at home and abroad. The carrier has four MOSS type independent spherical tanks, which can contain a total of 147,558m3 LNG. The heat insulation uses the Kawasaki panel system known as the proven heat-insulation effect. The boiloff gas rate is maintained at about 0.1% per day by the system. The cargo tanks are installed inside the cargo compartment built with double sides and double bottom to ensure safety sothat the cargo tanks are not damaged directly. The wheelhouse is equipped with advanced integrated electronic navigation equipment, which was previously installed separately. This has further improved ship operation tasks. Windows around the wheelhouse provide a panoramic view of 360 degrees, allowing one-man operation during ocean-going navigation. Cargo-handling operation is carried out at the cargo-handling room located in front of the accommodation quarters, where the Kawasaki IAS (an integrated controlling and monitoring system) is installed to monitor and control cargo handling operation as well as monitoring engine conditions. The IAS developed on the operator expertise basis is very easy to use. The carrier will navigate under cold sea conditions with atmospheric temperature of minus 25 degrees C and seawater temperature of minus 2 degrees C. Accordingly, all electrical and electronic apparatuses are protected from such severe conditions.

Moss Type LNG Carrier Alto Acrux
Mitsubishi Heavy Industries, Ltd. (MHI) completed construction of one of the large ships ALTO ACRUX (HN: 2219), a Moss type LNG carrier with a tank capacity of 147,798m3, and delivered to Kanto Leasing Limited at the Nagasaki Shipyard & Machinery Works on Mar. 31, 2008. The ship is designed to be compatible with Japanese, Korean and Taiwanese unloading terminals as well as Australian, South East and Middle East loading terminals. Main features are as follows. High propulsive performance and good maneuverability with less vibration level are achieved by the refined hull form and optimum design of propeller. Double side fuel oil tanks are adopted for purpose of environmental protection. Design fatigue life of 40 years based on North Atlantic wave data is applied to essential areas of hull structure and cargo tanks. Distributed control system is provided to  carry out the monitoring and control of the principal machinery and cargo handling, including main turbine,main boilers, feed water pumps, generator power management, boil-off gas treatment, auto ballast exchange, gas compressors, cargo pumps, spray pumps, and auxiliary machines.
