LPG cooling and reliquefaction
We have built up a number of references for the supply of our LPG cooling and reliquefaction plants onboard LPG FPSOs.
The high pressure LPG liquid stream requires cooling before it is expanded into the cargo tanks by the installed cooling plant. Our reliquefaction plants can be designed for operation on LPG with high ethane content in the LPG liquid phase and ensure that cargo condition at low pressure and temperature s down to -50°C in the cargo tanks.
Our supply of the world’s largest LPG handling system to Chevron’s Sanha LPG FPSO, with a storage capacity for 135,000m3, put us at the forefront of gas liquid cargo handling systems in this specialised market. The scope of equipment supply included large propane and butane cooling and reliquefaction plants, comprising skid-mounted units, a total of five cooling units served the reliquefaction plant, with two as the second stage in a cascade system. All equipment for the Sanha LPG FPSO was designed and manufactured in house with the cooling and refrigeration plants factory assembled as packaged units, tested and certified ready for installation inside the elevated deckhouse on the vessel’s topside.
