Abstract: A jack-up crane vessel or semi-submersible crane vessel is provided including a hull with a deck, and a crane on the hull for hoisting a load outside the deck. The crane includes a slewing crane base with a first suspension, an elongated boom that is rotatable around a horizontal rotation axis with respect to the first suspension, at least two pendants between the boom and the first suspension that mutually converge toward the distal boom section, a boom spacer between the boom and the first suspension, and a boom luffing installation for driving the rotation of the boom around the horizontal rotation axis between a lowered transport position and a raised operational position. In the direction of the vertical rotation axis the first suspension extends at least in the lowered transport position of the boom above the boom heel of the boom.

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.
