A system is disclosed to enable compliance of a well insert sleeve using a guide sleeve that is associated with a wash-out hole, where the guide sleeve includes a pivot shoulder. The system includes providing the well insert sleeve with a top portion, a bottom portion, and a pivot surface, so that the pivot surface is in contact with a pivot shoulder. The top portion is at a top clearance from the guide sleeve and the bottom portion is at a bottom clearance from the guide sleeve. The features altogether enable the compliance, in an angular manner, for the well insert sleeve during assembly of well components thereon.

A mounting device for an elongate member, comprising: an elongate housing having an elongate axis; an internal passageway passing through the elongate housing parallel to the elongate axis; an elongate sleeve located within the internal passageway and being configured for longitudinal movement along the passageway; a plurality of ball-receiving recesses in the wall of the internal passageway, each recess having a ball-guiding surface inclined to the longitudinal axis; a plurality of apertures in the sleeve; a ball located in each of the ball-receiving recesses and engaged with a respective aperture in the sleeve, the balls and the apertures being configured to allow the balls to project partially through the apertures but to prevent balls from passing through; biasing means configured to bias the sleeve in a direction to urge the balls to project radially inwardly through their respective apertures in the sleeve and into the internal passageway.

An end fitting for a subsea riser comprises an engagement head to be engaged with a subsea foundation in a vertically downward longitudinal direction. A structure of the end fitting surrounds a longitudinally extending flow axis and is arranged to bear a tensile load on a load path extending longitudinally from the engagement head parallel to the flow axis. The structure includes a pivot joint assembly having a first part attached to or integral with the engagement head and a second part pivotable relative to the first part about a centre of rotation substantially aligned with the flow axis. The structure can be fixed to the engagement head or removably attached to the engagement head. The engagement head supports an upwardly facing connector hub that is offset laterally from the flow axis. A connector pipe in fluid communication with the connector hub extends from the flow axis to the connector hub. A counterweight is opposed to the connector hub and the connector pipe about the flow axis.

A foundation for a subsea assembly is provided. The foundation includes connection points. The connection points permit other components to be connected to the foundation and permit loads to transfer from the other components into the foundation. The foundation may be a suction anchor. A method of converting an exploration well using the foundation to a production well is also provided.
