In an initial position, the two sections 12, 14 of a mooring line are not connected and the connector members 52, 54 are spaced apart, for example by 100m to 200m. The length of the mooring line sections are preselected such that the subsequent connection provides a pre-tensioned mooring line (10, Fig 1) at the required pre-tension. A mooring line tensioner 20 comprises a first engager 22 which engages with and grips/clamps a first connector/end 52 of a first section 12 of a mooring line. The mooring line tensioner comprises a second engager 24 which engages with and grips/clamps a second connector/end 54 of a second section 14 of the mooring line. A flexible tensioning line 40 is engaged around a pulley system 32, 34 provided on the engagers. An upper end of the tensioning line may be engaged with a winch which is arranged to wind the tensioning line on to a spool which pulls the two engagers towards each other until the connectors connect. Once the connectors are connected the mooring line tensioner is removable from a position around the now contiguous mooring line. An offshore assembly including the tensioner and a method of use are also disclosed.
