Title
(EN) Marine tensioner
Abstract
(EN)

The invention is directed to a marine tensioner (1) for handling an elongated article from an offshore vessel. The tensioner comprises a tensioner frame (11), multiple track units (20), wherein each track unit comprises an elongated chassis (30) and an endless track supported by said chassis, wherein between the chassis of each track unit and the tensioner frame a connecting structure (40,140) is provided that at least allows for lateral motion of the track unit with respect to the passage axis (26) so as to adapt the position of the track unit. For each track unit a group of hydraulic squeeze cylinders (50a, 50b, 50c) is provided between the tensioner frame and the chassis of the track unit. The tensioner further comprises a tilting mechanism (60) for the group of squeeze cylinders of each track unit, said tilting mechanism being adapted to tilt the hydraulic squeeze cylinders of a track unit between an operative position, wherein the squeeze cylinders are operative to exert a squeeze force in use of the tensioner for handling an elongated article, and an oversized article passage position.
