Abstract
A termination assembly for a steel tube umbilical, wherein a plurality of the elongated umbilical elements which compose the umbilical are steel tubes, said termination assembly comprising a cavity through which said tubes pass, said cavity being filled with a filler material, at least one of said tubes having at least one region of increased localized diameter at a location within said cavity to define at least one load bearing face on the tube to anchor said at least one tube within said cavity.
Claims13
A termination assembly for a steel tube umbilical for a subsea installation, the umbilical including a plurality of elongated umbilical elements comprising steel tubes, said termination assembly comprising;
- a cavity configured to receive said steel tubes, said cavity being filled with a filler material,
- wherein at least one of said steel tubes has at least one region of increased localised diameter at a location within said cavity;
- said at least one region defining at least one load bearing face on the at least one steel tube, said at least one region configured to anchor said at least one steel tube within said cavity;
- wherein said region of increased localised diameter is defined by a collar having an inner diameter substantially equal to the outer diameter of said at least one steel tube;
- wherein said collar is formed from a material compatible with the steel tube metal and is welded to said at least one steel tube.
A method of forming a termination assembly for a steel tube umbilical for a subsea installation, wherein a plurality of elongated umbilical elements which compose the umbilical are steel tubes, the method comprising the steps of:
- passing said steel tubes through a cavity within said termination assembly;
- forming at least one region of increased localised diameter on at least one of said steel tubes at a location within said cavity to define at least one load bearing face on the tube;
- filling the cavity with a filler material to anchor said at least one tube within said cavity by means of said at least one region of increased localised diameter,
- wherein the step of forming at least one region of increased localised diameter on at least one of said steel tubes comprises welding a collar around said at least one tube at said at least one region.
