The fi rst of three bulk carriers was de- livered to Archer Daniels Midland Com- pany (ADM), unique in that the ship fea- tures a host of innovative technologies, including the Mitsubishi Air Lubrication

System (MALS), which reportedly helps the ship to achieve a 27% reduction in

CO2 emissions as compared to conven- tional bulk carriers of the same capacity.

Developed by Mitsubishi Heavy Indus- tries, Ltd. (MHI) and built at Oshima

Shipbuilding Co., Ltd. of Nagasaki, an

MHI licensing partner, the centerpiece of the new ship is the incorporation of

MHI’s proprietary Mitsubishi Air Lu- brication System (MALS), which is de- signed to reduce frictional resistance be- tween the vessel hull and seawater using air bubbles produced at the vessel bot- tom. The new ship series was ordered by

ADM in 2011, and delivery of the three vessels is scheduled for completion by mid-2015. The carriers are 777.5 ft. (237 m) in length, 131.2 ft. (40m) wide with a 41 ft. (12.5m) design draft and a dead- weight tonnage (DWT) of approximate- ly 95,000 tons. In addition to the MALS system, the new vessel features a new bow shape designed to reduce wave- making resistance.

Harvest Frost Ship Floats on Bubbles

Norwegian ferry operator Norled AS received the battery-driven car ferry

ZeroCat 120, an aluminum catamaran which is light-weight with slender twin hulls. Its electric power train was de- signed by Norway’s Fjellstrand shipyard with battery technology from Germany’s

Siemens. The ZeroCat 120 does not dis- charge greenhouse gases, CO2, methane or nitrogen oxides to the environment. In addition to the environmental benefi ts, the ferry’s operational and maintenance costs will be lower than those of a con- ventional ferry. Norled will operate the world’s fi rst battery-driven ferry on the

Lavik-Oppedal route in south-west Nor- way. The 265 ft. (80.8 m)-long vessel will be able to carry 120 cars and 350 passengers across the Sognefjord. It will run 34 times each day, with a crossing time of 20 minutes. Time at port is 10 minutes, during which the 1-MWh lith- ium-polymer battery pack on board will be fully charged. This amount of electric power delivered in such a short time is far beyond the capacity of the electrical grid serving the villages of Lavik and

Oppedal. The solution is to install battery buffers at both ports that can be continuously charged from the grid with 250 kW, then rapidly provide a quick dump to the ferry’s batteries.
