ABS class contract for LNG carriers

14 May 2014

ABS is to classify two ‘Moss-type’ LNG carriers to be built in Korea for Malaysia’s Petroliam Nasional Bhd (Petronas).

The 150,200m³ capacity ships are expected to be the largest Moss-type units ever built at Hyundai Heavy Industries’ shipyard in Ulsan, Korea, featuring the latest technology to improve energy efficiency and operational reliability.

"Not only do we have the largest order book for LNG carriers among class societies, all of the current LNG cargo-containment systems - Moss, GTT's Mark III and No. 96 membrane types, and SPB types - have been installed on ABS-classed ships,” said Patrick Janssens, vice president for global gas solutions, ABS.

To boost their performance, reliability and ease of maintenance, the Petronas vessels will adopt new ultra-steam turbine propulsion systems, which are expected to be around 15% more energy efficient than conventional steam turbines.

The Moss-type cargo tanks will measure 42m in diameter, and because they have no minimum filling limits, they are well suited to serve as shuttles to and from FLNG or other offshore facilities.

The vessels will also feature full-length tank covers integrated into the main hulls, a feature which Petronas says is expected to improve longitudinal strength and minimise structural discontinuity. 

This contract comes just months after ABS unveiled its new Global Gas Solutions team, a multi-disciplinary group of technical experts formed to respond to the rapidly escalating number of gas-related projects, including LNG and LPG transportation, the use of LNG and LPG as fuel and the growing number of FLNG projects.
