摘要
A marine tensioner has a tensioner frame and multiple track units mounted in the frame. Each track unit comprises an elongated chassis, the chassis having a central portion between two end portions. Each track unit comprises an endless track supported by the chassis, the endless track having friction elements adapted to engage an elongated article. Between each track unit and the tensioner frame a connecting structure is provided that allows for lateral and pivotal motion of the track unit so as to adapt the position of the track unit to an elongated article diameter. One or more squeeze actuators are provided between the tensioner frame and the chassis of the track unit and actuator control means are provided which are associated with the one or more squeeze actuators and allow to control the squeeze force exerted by the friction elements of the track unit on the elongated article.
