Commissioning process underway for LNG vessel safety system

Published by , Editorial Assistant
Hydrocarbon Engineering,

Engineers from Severn Glocon Technologies have visited Korea to commission a high integrity pressure protection system (HIPPS) supplied to shipbuilder DSME for a floating storage and regasification unit (FSRU).

The LNG FSRU vessel, BW Magna, has a capacity of 173 400 m3. The HIPPS has been integrated and installed by Severn Glocon Technologies to protect the pipeline during the unloading of gas, enhancing safety for the FSRU and the downstream equipment and pipeline in the docking terminals it connects with.

HIPPS are not mandatory on FSRUs, but it is increasingly agreed that they provide a superior level of safety and reliability. Situated between high-pressure upstream and low-pressure downstream units, they contain media if over-pressurisation is likely to occur, rather than venting.

The system supplied to DSME operates at a working pressure of 117 barg. It comprises two 18 in. 900-class manual valves, a Sella Controls logic solver and three pressure transmitters.

Additional safety measures on the FSRU include alarms, a shutdown system, blow down system and safety valves, as per industry-specified standards.
