Abstract
A vessel is adapted to perform subsea wellbore related operations including module handling and laying flexible pipeline, e.g. wellbore intervention. The vessel includes a hull with a moonpool and a stationary drilling mast adjacent said moonpool. The front side of the drilling mast is provided with vertical trolley rails along which—during module handling—a module handling trolley is movable. Further one or more tensioners are provided to engage a flexible pipeline, also being supported by the by the drilling mast. The tensioner frame of a tensioner is mounted pivotably about a vertical pivot axis to the drilling mast, such that the tensioner frame is pivotable between the pipeline laying configuration wherein the lower tensioner is provided in the module handling area and an open configuration wherein a vertical trolley path is unobstructed to allow module handling.
