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 riser assembly (105) that can be suspended from a marine structure (102) is disclosed. The intake riser assembly includes at least a first tubular conduit (106) extending along the length. The distal portion of the first tubular conduit includes an intake section (109). The withdrawal section includes a tubular section having a sidewall defining a flow path in the longitudinal direction, having a bore having a first cross-sectional area, surrounding the longitudinal extent. A plurality of through holes (405) forming a plurality of intake openings are formed in the side walls. The total area defined by the plurality of through holes is greater than the first cross sectional area.;
