A marine pipeline - installation tower (2) comprising at least two opposing legs (22,26), and one or more tensioning assemblies (10,30) supported by the opposing legs for surrounding and supporting an intermediate pipeline (6) during installation, at least one of the intermediate tensioning assemblies (10,30) comprising two or more discrete segments (32,34), being a first segment and at least a second segment, the segments being moveable between: a closed position wherein the segments (32,34) are conjoined to form an enclosing pipeline annulus able to support the pipeline between the legs of the tower; and an open position wherein at least two of the segments (32,34) are disconnected and separate. In this way, a better clearance is achievable between the parts of the segments able to form the enclosing pipeline annulus when the segments are in their open position, because the segments are able to be disconnected and separate despite still being supported within the limited room between the fixed legs of the tower.
