SEOUL, South Korea — ABS has awarded approval in principle (AIP) for the Hi-ReGAS+ regasification concept, developed by Hyundai Heavy Industries (HHI) subsidiary Korea Shipbuilding & Offshore Engineering.
The system is applicable to floating storage regasification units (FSRUs) and floating liquefied natural gas (FLNG) terminals. It is a follow-on model to the HHI Group’s Hi-ReGAS system.
According to ABS, the concept’s natural circulation system uses the density difference of the fluid in the intermediate system that transfers heat from seawater to LNG. This is said to result in an energy-efficient circulation system process with reduced energy consumption.
HHI built a demonstration facility on a scale of 1/100 of an actual regasification system to verify the performance. Based on the experience from long-term operation of the facility, the group identified improvements and applied this to the design., with ABS subsequently issuing AIP for this ship class.
