A gooseneck assembly having a body disposed circumferentially about a portion of a riser string. A stab member is inwardly radially extendable relative to the body and engages a receptacle disposed on the riser string. A cartridge assembly engages the stab member and has a flexible hose coupling that is rotatable relative to a central axis of the stab member. The coupling is in fluid communication with the receptacle via the stab member. The assembly includes an actuator that is operable to rotate the flexible hose coupling relative to the central axis of the stab member.

A keel joint protector, which, in certain aspects, includes a body made of flexible material, a central open bore through the body, and the body having a plurality of spaced-apart energy management zones therein for diffusing a force applied to a particular part of the body. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72(b).

Energy managing keel joint

The shear ram assembly for shearing an oil well tubular T includes a first ram axially moveable along the first axis for moving an upper blade , and an opposing second ram axially moveable along the second ram axis for moving a lower blade . An upper planar surface of the lower blade passes closely adjacent a lower planar surface of the upper blade as the blades move towards each other to shear the tubular. The sealing system is positioned within a recess in the upper surface of the lower blade, and includes an elastomeric seal for sealing engagement with the lower planar surface of the upper blade and a rigid actuator moveable relative to the lower blade to energize the elastomeric seal.
