DNV Wins KOGAS' Technology Qualification Contract for Liquefaction Plant

Norway's DNV GL reported Monday that DNV GL Korea has been awarded a technology qualification (TQ) contract with Korea Gas Corporation (KOGAS) for a front end engineering and design (FEED) Package for a 5 million tons per annum (Mtpa) onshore LNG (liquefied natural gas) liquefaction plant based on the innovative KSMR liquefaction process.

KSMR is a new natural gas liquefaction process and is for LNG plants and floating LNG due to its compactness. A pilot KSMR LNG liquefaction plant of 100 tons per day is being constructed by KOGAS to verify the operability and the efficiency at the Incheon LNG receiving terminal in Korea.

KOGAS has invited DNV GL to perform a TQ in line with DNV GL’s Recommended Practice DNV-RP-A203. This will provide assistance on the identification and mitigation of areas of uncertainties alongside quantification of the risks associated with application of this novel technology for onshore application. 

“Korea is a major oil importing nation and is driving forward plans to increase the share of natural gas in their energy mix, mainly through LNG import,” said Rolf Benjamin Johansen, DNV GL’s Regional Manager for Korea and Japan. “Our experience in the complete lifecycle of LNG production allows us to develop customer-specific solutions from risk management to effective asset operation. Our methodology quantifies and mitigates risks from the earliest project stages.” 

In addition to the TQ process, DNV GL will also review the process simulation report of the KSMR LNG liquefaction process involving natural gas liquid recovery, liquefaction, end flash and refrigeration, in line with KOGAS design specification.  

“As a technical advisor, we deliver a world class systematic process for TQ through the Recommended Practice (RP) DNV-RP-A203,” added Johansen. “The RP describes definite steps to ensure that the new product meets the requirements initially set. Successful completion of the TQ project will enable KOGAS to have a solid reference to secure the FEED package for LNG FPSO topside process based on this new KSMR™ liquefaction process.”  

DNV GL has supported KOGAS to set the Qualification Basis which is the initial stage of  the TQ process, which is likely to continue into 2016. As part of the Technology Assessment, a first workshop has been held for the technology categorization and identification of the main challenges and uncertainties related to the novel technology aspects of the KSMR process. The workshop was attended by a multi-discipline team  of specialists from KOGAS, Dong Hwa Entec (heat exchanger) and Samsung Techwin (compressor).The next TA workshop is scheduled for May 2015 at KOGAS’ Incheon LNG Terminal where the KSMR pilot plant is located.
