ABSTRACT:
The invention is an underwater LNG pipeline system in modular sections wherein multiple LNG pipelines utilizing expansion joints to compensate for contraction are connected together by braces to form an integral frame, and including pressure vessels enclosing the expansion joints to permit access to the expansion joints for inspection or maintenance. In a second embodiment, the frame is a separate elongate space frame connected to the pipeline and the pressure vessels. In a third embodiment, the pipelines are INVAR steel and no expansion joints or pressure vessels are included.
