“The large number of proposed LNG projects currently vying for public and governmental approval on a global basis has lead to an increased focus on associated safety, economics, environmental, and aesthetic issues.
LNG project teams will consider designing LNG terminals using subsea or buried onshore LNG pipelines in an effort to offer safe; robust, cost-effective, and environmentally and visually appealing alternatives to more traditional technology.”
AMEC Paragon used this approach for the Camisea LPG export terminal offshore Peru. Using InTerPipe’s (ITP) subsea cryogenic pipeline system, AMEC Paragon proposed a marine export terminal design that allowed the client (Pluspetrol SA, Buenos Aires) to obtain critical local approval for the project. This article discusses the technical, economic, safety and local acceptance advantages of a terminal based on subsea or buried onshore pipelines.”
