ESD systems for MLNG plant module 4

For the MLNG plant module 4 in Bintulu Malaysia, our Valve Actuation team delivered a number of ESD systems comprising 5 Hydraulic Power Units, 8 Local Operating Panels and 8 Gate valves with hydraulic actuator. The actuators are enclosed in a UL1709 certified fire proof box to keep the valves functional in case of a local fire. All systems are designed and manufactured in full accordance with the Shell DEP / PTS

The Petronas MLNG plant is a huge LNG plant that is located in Bintulu, in the Malaysian state of Sarawak. The plant started production in 1983 and has a total production capacity of 23 million tons per annum of LNG. The LNG plant acquires its natural gas from 125 kilometres to 225 kilometres offshore of Bintulu. As the end-user wants the plant to continue operating reliably for the next 20 years, a project to rejuvenate the Plant was initiated.
