Daewoo Shipbuilding Applies Self-Developed Re-liquefaction System to Two LNG-FSUs

[Asia Economy Reporter Park Soyeon] Daewoo Shipbuilding & Marine Engineering announced on the 25th that it applied a newly developed re-liquefaction system to two 360,000㎥ liquefied natural gas storage and transshipment facilities (LNG-FSUs) ordered in June from shipowners in the Russia region.

According to Daewoo Shipbuilding, the natural gas re-liquefaction system is a device that re-liquefies natural gas that naturally vaporizes in the cargo hold and returns it to the cargo hold, serving as a key equipment to improve the operational efficiency of LNG-FSUs and LNG carriers.

The newly developed re-liquefaction system is the result of Daewoo Shipbuilding's long-accumulated LNG-related technology, maximizing efficiency by using nitrogen as a refrigerant while recovering LNG cold energy to the fullest.

Through in-house design, major equipment such as compressors and expanders were localized in collaboration with Hanwha Power Systems, contributing to enhancing the competitiveness of the domestic equipment industry.

Daewoo Shipbuilding stated that it is meaningful in that core equipment developed domestically was applied for the first time to offshore plant-grade facilities.

Daewoo Shipbuilding provides remote monitoring and optimal operation support services with its self-developed technology for LNG-FSUs.

By checking the status of each equipment, it suggests optimal operating conditions and enables smart maintenance.

Daewoo Shipbuilding said it now has re-liquefaction systems for each field, including partial re-liquefaction systems and full re-liquefaction systems for high-pressure and low-pressure engines.

Choi Dong-gyu, Executive Vice President and Head of the Central Research Institute at Daewoo Shipbuilding & Marine Engineering, said, "We have conducted research and development in the LNG field for over 20 years and have established the Energy System Testing Center in 2015 to carry out demonstration research and development, which has led to our current LNG technological competitiveness," adding, "We will do our best to develop products incorporating various eco-friendly and digital technologies and to localize equipment."

The LNG-FSUs equipped with the re-liquefaction system are scheduled to be constructed by the end of 2022 and to depart for the installation sites in Murmansk and Kamchatka regions of Russia.
