OFFSHORE LNG TERMINAL REVIEW: SMALL SCALE GAS RECOVERY SYSTEMS FOR HOSTILE ENVIRONMENTS

Publicised offshore gas liquefaction terminal concepts have been reviewed and it is concluded that some semi-submersible and surface floating ship/barge systems can best fulfill the requirements of small-scale, short-life gas supply recovery. Mixed refrigerant and turbo-expander liquefaction cycles can operate on offshore terminals, the choice being dependent upon logistic and safety aspects of the former and the higher fuel costs of the latter. Other principal areas of technical risk are high-lighted and an LNG terminal to carrier transfer system based upon flexible hose described. A gas gathering system based upon the application of a number of gas liquefaction terminals is presented and a financial appraisal conducted to relate sensitivity of various key parameters to landed gas costs. It is established that gas supplies of 35 MMSCFD and above can be recovered at costs comparable with other landed LNG supplies.
