Air-lubrication of a ship’s hull really does pay off with significant fuel savings. Just a few days ago NYK Line announced that trials of the Mitsubishi Air Lubrication System (MALS)  in not one, but two of its module carriers in a variety of normal operating conditions over a two-year period had been completed and confirmed an average 6% reduction in fuel consumption. Long Term Operational Trial An air-lubrication system was installed in each of twin-designed NYK-Hinode Line ocean-going vessels, the 19,800 dwt diesel-engined heavy equipment carriers ‘Yamatai’ and ‘Yamato’; the first in March 2010, and the other in the following November. MV Yamatai: Photo credit NYK Line These two ships are special heavy load carriers with roll-on, roll-off rampways for the transport of large prefabricated structures. Their propulsion system is by twin shaft CPP propellors, powered by a pair of Daihatsu 6DKM36 diesel engines, maximum rating 3.218 KW at 600/196 ... [More]

Carnival Corporation’s German subsidiary AIDA Cruises has two 125,00 GT passenger ships each with a capacity of 3,250 passengers is presently under construction at MHI, Japan, with completion dates scheduled for the second quarter 2015 and second quarter 2016. They will use the Mitsubishi Air Lubrication System (MALS) whereby blowers bleed air bubbles through small holes in the ship’s bottom to produce a carpet of air which reduces friction. In this first application on a cruise ship, MHI predict a fuel saving of around sever per cent for the two AIDA vessels. The AIDA cruise ships will use a diesel electric propulsion system driving two ABB Azipod XO2100 azimuth thrusters each with a rated output of 14 MW. [More]

Sauter Carbon Offset Design (SCOD) presented earlier this month, their latest project, Emax
Deliverance - a DynaWing Solar Hybrid Supertanker. The 330,000 dwt tanker is designed to
pass through the larger locks of the post 2014 Panama Canal. The hull is slender and uses a
Mitsubishi Air Lubrication System (MALS) that reduces resistance and therefore delivers higher
efficiency. Propulsion is by a twin arrangement of a pusher propeller with a counter rotating
puller propeller on steerable pod, powered by W„rtsil„ dual fuel LNG engines with additional
power coming from a Solbian solar power generating array, in addition there are twenty masts
supporting DynaWing sails. A nett benefit is claimed to be a reduction in GHG emissions of
between 70 to 85 per cent equating to a total reduction of CO2 of 3 million tons over the 25 year
life of the vessel. [More]
