发明名称 Apparatus for installing a flowline section near the seabed
摘要 An apparatus for securing a flowline to a structure near the seabed comprises a vertically oriented guide funnel placed atop a guide tube that is provided with a helical shoulder cooperating with an alignment key mounted on the flowline. During installation the flowline is stabbed into the guide funnel and guide tube thereby causing the alignment key to slide along the shoulder until a pair of hinge pins mounted on the flowline have entered into a pair of slots in the wall of the guide tube. Subsequently the flowline is hinged down to a horizontal position.
