Abstract
A subsea termination assembly comprising a main body, a stab pin with a stabbing end for guiding of the subsea termination assembly during landing on a receiving subsea structure, and a hinge assembly connecting the stab pin to the main body. The subsea termination assembly comprises a connected portion that is pivotably attached to the main body with the hinge assembly. The stab pin comprises a free portion and the free portion comprises the stabbing end. The subsea termination assembly comprises a stab pin connection arrangement, detachably connecting the free portion to the connected portion. A method is also disclosed.
Claims11
A subsea termination assembly comprising
- a main body,
- a stab pin with a stabbing end for guiding of the subsea termination assembly during landing on a receiving subsea structure, and
- a hinge assembly connecting the stab pin to the main body,
- characterized in that
- the subsea termination assembly comprises a connected portion that is pivotably attached to the main body with the hinge assembly,
- the stab pin comprises a free portion,
- the free portion comprises the stabbing end,
- the subsea termination assembly comprises a stab pin connection arrangement detachably connecting the free portion to the connected portion.
A method of installing a subsea termination assembly, having a main body, at a subsea location, comprising the following steps:
- a) at a floating structure, installing a utility string, which is connected to the main body, in a tensioning system;
- c) lowering the termination assembly from the floating structure towards the seabed;
- d) at the seabed, inserting a stab pin, which is attached to the main body through a hinge assembly, into a guide funnel;
- e) pivoting the main body with respect to the stab pin, thus landing the main body onto a receiving subsea structure;
- characterized in that the method further comprises, between steps a) and c):
- b) attaching a free portion of the stab pin to a connected portion, wherein the connected portion is attached to the main body with the hinge assembly.
A subsea termination assembly comprising
- a main body,
- a stab pin with a stabbing end for guiding of the subsea termination assembly during landing on a receiving subsea structure, and
- a hinge assembly connecting the stab pin to the main body in a pivotable manner,
- a yoke with a lifting eye;
- characterized in that the hinge assembly comprises a trunnion pin which is attached to the main body, and that the stab pin and the yoke are connected to the trunnion pin, such that the yoke and the stab pin can pivot about the trunnion pin.
