The BW Magna vessel has a capacity of 173 400 m3. According to the statement, the HIPPS has been integrated and installed by Severn to protect the pipeline during gas unloading operations, improving safety for the vessel, as well as for the downstream equipment and pipeline in the docking terminals its connects to.
Severn claims that HIPPSs are not mandatory for FSRUs, but it is becoming increasingly recognised that they provide an excellent level of both safety and reliability. Located between high pressure upstream and low pressure downstream units, they contain media if over-pressurisation is likely to occur, rather than venting.
According to the statement, the system that was supplied to DSME operates at a working pressure of 117 barg. It consists of two 18 in. 900-class manual valves, a Sella Controls logic solver and three pressure transmitters.
Site Manager Tim Blake said: “Effective HIPPS integration demands electronic and mechanical engineering skills, with software engineering input sometimes needed as well.
“It’s important that these specialist engineers interrogate the design brief and collaborate with functional safety professionals. This is where using an independent integrator offers a major advantage. At Severn, we employ all of these professionals in house.”
Further safety measures on the FSRU include alarms, a shutdown system, blow down system and safety valves, as per industry-specified standards. The benefits of adding a HIPPS is that it is a simple, proven solution, which can operate independently of the wider vessel system.
