Maran Gas Maritime, the gas shipping unit of the Angelicoussis Shipping Group, is set to use induction-based electric propulsion motor technology from GE’s Power Conversion business to power its four new LNG carriers.
The vessels, which are being built by Korea-based shipbuilder Hyundai Heavy Industries, will be delivered from July 2015.
GE will supply two propulsion systems, which will include generators, main and cargo switchboards, transformers, MV7000 converters, motors and remote control.
The propulsion system developed by GE features PWM variable-speed drives that are a highly reliable and cost-efficient solution for marine drive systems, according to GE.
The company said the system has lower maintenance costs, lower fuel consumption and emission rates, and longer service life with higher environmental benefits.
The electric drive system is powered by tri-fuel engines that can run on natural gas, marine diesel gas or heavy fuel oil.
In August 2013, Maran took delivery of its first LNG carrier, the Woodside Rogers, powered by GE’s electrical power and propulsion system.
The carrier was the first of the 15 GE-powered vessels to be built by South Korean shipyards for Maran Gas.
Maran Gas technical director Andreas Spertos said after looking at the growth potential of the LNG market, the company took the strategic decision early in 2011 to expand its presence in LNG shipping and add to its then existing fleet of five LNG carriers.
"The Woodside Rogers is our first tri-fuel carrier, and we are pleased with the way the ship performed during sea trials," Spertos said. "We believe we have made the right decision to apply fuel-efficient, tri-fuel diesel-electric technology to our new generation of vessels."
GE Power Conversion marine business leader Paul English said it is very satisfying for the company that one of the most important shipbuilding companies in the world has recommended GE’s innovative electric power systems for LNG vessels in recent months.
"Our strength in technology and attention to customer needs has helped us create excellent working relationships with both Hyundai Heavy Industries and Maran Gas," English said.
