A hang-off insert 28 for hanging-off a flexible elongate subsea element 10 from a surface vessel has a circular loop that comprises circumferentially-spaced support segments. Collectively, the segments define a substantially planar support face 34 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 28 supported by a hang-off structure of the vessel, a laterally-protruding hang-off feature 16 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.
