A tensioner system holds back elongate products such as subsea pipelines being laid into water. The system comprises at least one endless circulatory track and an array of rollers supporting the track. Each of the rollers of the array is mounted for rotation around a respective shaft. At least one of the shafts comprises a load pin that is arranged to sense loads applied to the surrounding roller in directions normal to an axis of rotation of that roller.

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.
