  • Hold crane as well as pipefeeder vessel with such hold crane
    Patent number: 9315244
    Abstract: A hold crane (6) for elongate elements (4), such as a pipe hold crane for a pipefeeder vessel (1), includes a main frame (7) and support elements (9-12) supporting the main frame above a hold which is carried out for containing the elongate elements. The support elements allow displacement of the main frame in a longitudinal direction of the hold. Hoisting members are provided which are carried by the main frame for lifting an elongate element from the hold vice versa, the hoisting members including at least two hoisting elements spaced apart in the longitudinal direction of the hold. The hoisting elements are suspended from the main frame and are provided coupling elements for coupling onto an elongate element. Stabilizing elements, which cooperate with the hoisting elements, prevent movement of the coupling elements in transverse direction with respect to the main frame while allowing vertical movement of the coupling elements.
