Abstract

Official abstract text for this publication.

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 ( 50 a, 50 b, 50 c ) 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.

First claim
