摘要： An apparatus for supporting a steel catenary riser (SCR) from a floating structure having a keel includes a flexible support tube or keel sleeve through which the SCR passes. The support tube or keel sleeve includes a pivot mechanism that is lockably received in a receptacle fixed to the floating structure. A method of supporting an SCR from a floating structure includes the steps of inserting a first end of the SCR into a support tube or keel sleeve; fixing the support tube or keel sleeve to the SCR; pulling the support tube or keel sleeve into a receptacle fixed to the floating structure; releasing the support tube or keel sleeve from the SCR; pulling the SCR through the support tube or keel sleeve up to an attachment point on the structure; fixing the SCR to the structure; and fixing the support tube or keel sleeve to the SCR.

摘要： A tensioner system for a top-tensioned riser in a floating platform includes a hydro-pneumatic tensioner assembly resiliently mounted to the floating platform, and a riser support conductor surrounding the riser coaxially, wherein the support conductor conveys a pull-type tensional force from the hydro-pneumatic tensioner assembly to the riser through a riser conductor coupling assembly that engages the tensioner assembly and the riser support conductor to convey the tensional force. A riser tension joint support assembly conveys the tensional force from the riser support conductor to a riser tension joint on the riser. The tensioner assembly compensates for relative platform motion including pitch, heave, and yaw. Also a reactive load assembly is mounted to the platform and reacts to a two-point dynamic bending moment imposed on the riser support conductor, while resisting riser support conductor rotation.
