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 stretching 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.

主权项

1. A water intake riser assembly that is suspendable from an off-shore structure, comprising a bundle of at least a first tubular conduit and a second tubular conduit generally stretching side by side along a length direction, each comprising, seen in the length direction, a proximal portion comprising suspension means, followed by a connecting portion, followed by a distal portion comprising a water-intake section, said distal portion extending between a first distal end and the connecting portion of the respective tubular conduit, said connecting portion fluidly connecting the proximal portion and the distal portion, the first and second tubular conduits being laterally connected to each other by means of at least one spacer engaging the respective connecting portions, wherein at least a part of the distal portion of the first tubular conduit extends further in the length direction than the second tubular conduit when in fully suspended condition.
