ABS grants AiP for LNG-fuelled ships, launches guide for LNG barges

03 Feb 2019

The American Bureau of Shipping (ABS) has recently issued an Approval in Principle (AIP) to two liquefied natural gas (LNG) powered designs from China’s Dalian Shipbuilding Industry Group Co (DSIC), while launching a guide for LNG barges.

DSIC’s designs include a 208,000 dwt bulk carrier and a concept 260,000 dwt Very Large Ore Carrier (VLOC).

“ABS has extensive experience of LNG as a marine fuel and it is a privilege to work closely with DSIC on these projects,” said Patrick Janssens, ABS Vice President, Global Gas Solutions.

“China shipbuilders have a fantastic record of innovation in LNG and, as a recognized global leader in gas, ABS is proud to assist these significant industry technological developments.”

Both designs incorporate a Type C LNG fuel tank in the open area of the aft deck, which DSIC says minimises the influence on the arrangement of the deck house and increases cargo capacity.

“LNG is quickly becoming the alternative fuel of choice,” said DSIC.

“By working with ABS, we are able to demonstrate the viability of our designs as a solution for shipowners and operators examining the feasibility of LNG as fuel for their vessels.” 

ABS, meanwhile, has released a guidance to assist shipyards and barge operators:  The Guide for Building and Classing Liquefied Gas Tank Barges with Remote Control and Monitoring of Essential Systems.

The Guide provides requirements for the design and construction of barges equipped with various degrees of automation, remote control and monitoring of essential systems supporting cargo management. The barges may be unattended and controlled primarily from the towing vessel’s navigation bridge.

Gas as fuel has become an increasingly popular option for many shipowners looking to comply with environmental regulations and gain new operational efficiencies, says ABS.

Liquefied gas tank barges are key to help expand the LNG supply chain and advance adoption of LNG as fuel.

“We are focused on developing practical guidance and solutions that respond to the challenges faced by owners and operators while ushering in new concepts and advancing the latest technologies,” notes Janssens.

The Guide is intended to be used in conjunction with the ABS Rules for Building and Classing Steel Barges, ABS Rules for Building and Classing Marine Vessels and the ABS Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal Waterways.
