Comparison of Various Offshore Industrial Gas Technologies

Offshore oil-exploration drilling and testing are key for the production of oil; however, a number of associated challenges, particularly the handling of associated gas, must be overcome. This paper discusses the alternatives for processing the associated gas and transporting it to markets. The technologies described in this paper are applicable to nonassociated-gas projects as well. Fig. 1 provides a description of gas-handling value chains for some of the alternatives.

Floating Liquefied Natural Gas (FLNG)

Liquefied natural gas (LNG) is natural gas that has been converted to liquid form for ease of storage or transport. It is a gas cooled to −162°C and has a volume that is 1/600 that of the gas at room temperature. The gas has to be processed at both ends of the shipping chain in order for LNG to be produced and used. It can be transported by specially designed cryogenic sea-going vessels (LNG carriers). At the destination, the LNG is offloaded to a receiving terminal that stores it and revaporizes it into a pipeline that takes the natural-gas product to the end users.
