DSME delivers first LNG carrier with air lubrication
South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) has delivered the first LNG carrier to feature an energy saving air lubrication system.
Maran Gas Andros is one of a series of 173,400m3 LNG carriers ordered by Athens-based Maran Gas Maritime in June 2016 and was handed over this week. The ship features the DSME ALS (Air Lubrication System) developed in house by DSME.
The air lubrication system is an energy saving technology that injects air into the bottom of the ship to create a continuous air layer between the hull and seawater, thereby improving fuel efficiency by reducing frictional resistance during operation. By applying this system, it is possible to save more than 5% of fuel compared to existing LNG carriers. This is the first time this system has been applied to a newly built LNG carrier. However, it has been applied previously to container ships, LPG carriers and tankers.
DSME said that Maran Gas, was impressed by the performance of the system during sea trials last month and has asked to apply the technology to subsequent ships.
The ship is 294.9m in length and is a twin skeg design powered by a pair of MAN B&W 5G70ME-C9-GI engines.
