Coûts des installations de GNL : tendances actuelles et futures.

LNG plant costs: present and future trends.

Auteurs : DI NAPOLI R. N., YOST C. C. III

Résumé

New LNG projects are underway in Qatar, Oman, Trinidad and Nigeria. These projects are the first greenfield projects built in nearly 10 years. Contrary to past experience, capital investment per unit of production is 25-30% less, on a constant dollar basis, than previous projects. Cost reduction has been the subject of considerable discussion. The more cost effective designs currently being offered, however, are not the result of any single improvement or innovation but a combination of factors realized through the joint efforts of project sponsors, liquefaction process vendors, equipment suppliers and EPC contractors. The principal factors among these are the following: maximizing of individual liquefaction train production for available refrigeration power input and related equipment characteristics, reduction of over-design allowed for engineering unknowns, more cost effective arrangement and layout of equipment, renewed competition among process licensors and contractors.
