LNG, as a promising lower-emission alternative fuel has not been used for container vessels. DSME and Germanischer Lloyd (GL) have proved the feasibility of running large container vessels on LNG in a recently completed joint project. At a press conference held during the Kormarine Trade Fair in Busan, both parties announced the progress they have made towards developing LNG-fueled large container vessels. GL has recently finished approval in principle of a 14,000 TEU LNG-fueled container vessel for DSME.
New technology is needed as cleaner transport is increasingly demanded and maritime environmental regulations are becoming ever stricter. DSME and GL have acknowledged this challenge and agreed in 2010 to jointly start exploring technology options and safety concepts for large LNG-fueled container vessels.—Frederick Ebers, Vice President and Area Manager for North East Asia, GL
Dr. Gerd-Michael Wuersig, Deputy Head of Environmental Research Department of GL and also a member of IMO Correspondence Group for the development of the Code for Gas as Ship Fuel (IGF-Code), pointed out that most technical systems have been developed and examined and the major challenge lies in how to apply these technologies, especially the one ensuring safe bunkering procedures.
You have to guarantee there is no gas spill and protection measures against incidents and collisions are sufficient. Relevant solutions are under evaluation and will be available soon.—Gerd-Michael Wuersig
The IMO has agreed to reduce SOx emissions by controlling the sulfur content in marine fuels from 2015 onwards, and for new vessels operating in ECAs (emission control areas), 80% reduction of NOx emissions versus 2010 level is required starting from 2016.
This will make conventional fuel unattractive. But LNG can be an environmentally and economically sound option due to its high efficiency and lower impact on environment. LNG-fueled cargo ships will be emerging on a large scale in the latter half of this decade, and there is a great potential for container ships to become one of the first cargo vessels using LNG as ship fuel.—Gerd-Michael Wuersig
Currently, GL is involved in converting a 25,000 dwt product tanker Bit Viking into the first GL-classed gas-fueled ship.
