A hang-off insert for hanging-off a flexible elongate subsea element from a surface vessel has a circular loop that includes circumferentially-spaced support segments. Collectively, the segments define a substantially planar support face of the insert and have respective radially inner faces that define an inner radius of the loop. The radially inner faces of the support segments can be positioned at various radial positions to determine the inner radius of the loop and hence to adapt the circumference of the loop to suit different diameters of elongate subsea elements. With the hang-off insert supported by a hang-off structure of the vessel, a laterally-protruding hang-off feature of the elongate subsea element extending through the loop may be rested on the support face to transfer suspended weight loads to the hang-off structure.

A size-adjustable, pivotable triple-connection device is disclosed. The device has a first element with an upper hole and a lower hole and a second element with an upper hole and a lower hole. The second element is pivotable in relation to an axis of alignment of upper holes of the first and second elements, and aligning, when not connected by its lower hole, in relation to a vertical axis of the first element. The device also has a shackle with a pin that traverses the axis defined by the alignment of the upper holes of the first and second elements.
