WATER INTAKE RISER ASSEMBLY FOR AN OFF-SHORE STRUCTURE, AND METHOD OF PRODUCING A LIQUEFIED HYDROCARBON STREAM AND METHOD OF PRODUCING A VAPOROUS HYDROCARBON STREAM

摘要

A water intake assembly (105) is suspendable from an off-shore structure (102) is proposed. It has a bundle (106) of at least a first tubular conduit (106A) and a second tubular conduit (106B) generally streching side by side along a length direction. At least a part of the distal portion (109) of the first tubular conduit extends further in the length direction than the second tubular conduit when in fully suspended condition. Described used of such a water intake riser assembly include: a method of producing a liquefied hydrocarbon stream and a method of producing a vaporous hydrocarbon steam.
