A guide to FLNG (floating liquefied natural gas) - Oil & Gas IQ
网页2018年8月24日 · How does FLNG work? The FLNG facility is moored directly above the natural gas field. It routes gas from the field to the facility via risers. The gas is then processed and treated to remove impurities and liquefied through freezing, before being stored in the hull.
Current Forces on Prelude Hull and Water Intake Riser by CFD: Full ...
网页2021年10月11日 · The Prelude Floating Liquefied Natural Gas (FLNG) facility is moored with an internal turret allowing it to perform offloading operations of liquefied natural and petroleum gas products. It does so in either a Free Weathervaning (FW) mode, i.e. by allowing the unit to rotate according to environmental loads, or …

Innovative Caisson Type Seawater Intake Riser Design Concept for FLNG
网页2014年2月6日 · In order to achieve overall cost effectiveness, all FLNG (Floating Liquid Natural Gas) projects must use large volume of deep sea cold water for their cooling process. This has prompted FLNG projects hanging several risers (about 20 to 30 inch diameter) vertically straight down from the platform to a depth between 500 to 1000 feet.
FLNG Cold Sea Water Intake Risers - OnePetro
网页2014年3月25日 · One such initiative is the recent development of Floating Liquefied Natural Gas (FLNG) units which requires a lot of cold sea water to increase gas liquefaction process efficiency. At 160m below sea surface, the water temperature is 10°C lower than at surface and up to 16°C lower at some 320m water depth.
