ABS continues to demonstrate leadership in the safe handling and transportation of gas – both as cargo and for use as fuel in marine applications. As the demand for cleaner energy continues to grow, gas carrier designs are evolving to fill global trades and niche applications. Shipowners and yards are also examining the application of gas as fuel to conventional merchant ship designs in order to meet the stricter emissions limits.

ABS has granted Approval in Principle (AIP) for two new gas carrier designs from China’s Hudong-Zhonghua Shipbuilding, for a 200,000cbm LNG Carrier and a 147,000cbm Very Large Ethane Carrier (VLEC).

Hudong Zhonghua is a pioneer in design and construction of gas carriers and the AIPs demonstrate the commitment of ABS to promoting innovation to meet market needs and drive safer and more sustainable shipping, according to Eric Kleess, ABS Senior Vice President, ABS Eastern Hemisphere Operations. 

“In reviewing these novel gas carrier designs, ABS is able to draw on our extensive experience in the classification of VLECs in supporting the safer handling, storage and transport of gas,” he said.

“Hudong Zhonghua, with the support of ABS, has a proud record of innovation in the design and construction of gas carriers in China,” said Jin Yanzi, Hudong-Zhonghua Shipbuilding’s Vice President. “With the granting of these AIPs by ABS, these latest designs are now set to continue that tradition.”

The Hudong LNG carrier is designed for long-distance, large-scale LNG transportation, featuring enhanced cargo capacity and greater efficiency compared to conventional ships. The VLEC design is tailored for US-China routes, which can meet US Coast Guard requirements and is equipped with a dual-fuel propulsion system using ethane as the main fuel to meet local and global emission requirements.

ABS also granted AIP to two new LNG-fuelled ship designs from China’s Dalian Shipbuilding Industry Group Co (DSIC), including designs for a 208,000 dwt bulk carrier and a concept for 260,000 dwt Very Large Ore Carrier (VLOC).

DSIC believes that LNG is quickly becoming the alternative fuel of choice and by working with ABS, it is able to demonstrate the viability of its designs as a solution for shipowners and operators examining the feasibility of LNG as fuel for their vessels.

Through its legacy of work with several generations of gas carriers, ABS has extensive experience of LNG as a marine fuel says Patrick Janssens, ABS Vice President, Global Gas Solutions. “China’s 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 minimizes the influence on the arrangement of the deck house and increases cargo capacity. DSIC believes the optimized aft deck integrated arrangement resulted in a modular design concept for the LNG gas supply system, safety system and filling system and makes for convenient installation and maintenance.

ABS provides industry leadership, offering guidance in LNG floating structures and systems, gas fuel systems and equipment, gas carriers, and regulatory and statutory requirements. ABS also offers specification reviews, risk and hazard assessments, bunkering suitability reviews and feasibility studies.
