Abstract
The invention relates to a marine pipeline installation tensioner () for use on a pipeline installation vessel. A tensioner according to the invention comprises a lower track unit (), an upper track unit () and a tensioner frame (). The tensioner frame comprises multiple tensioner frame supports (), a lower support frame () supporting the lower track unit, an upper support frame () supporting the upper track unit, a set of lower support frame actuators () provided between the tensioner frame supports and the lower support frame, and a set of upper support frame actuators () provided between the lower support frame and the upper support frame and adapted to move the upper support frame relative to the lower support frame. According to the invention, the track units are positioned by positioning the tensioner frame sections () of the tensioner frame, and not by positioning the track units () relative to the tensioner frame. This allows for a more compact tensioner design.
