FLOW THROUGH FLANGE FOR A SHIP-TO-SHIP CARGO TRANSFER FLOW LINE

摘要

flange (100) for mounting to an end of a ship-to-ship cargo transfer line for transporting hydrocarbon liquids, the flange comprising: a base plate (110) including an orifice having a central axis and an outer radius; a blast plate (130) coupled to the base plate and coaxially aligned with the orifice, wherein the blast plate (130) is axially spaced from the base plate (110); wherein the blast plate (130) has an outer radius greater than or equal to the outer radius of the orifice and is configured to impede the flow of the hydrocarbon liquids from the flow line through the orifice, and wherein the blast plate (130) is configured to allow the flow of air into the flow line through orifice.
