Anchor handling device
An anchor handling device for an anchor handling vessel, the anchor handling device being adopted to bring an anchor from a substantially horizontal position resting at an aft deck of the vessel, to a substantially vertical position hanging astern of the vessel, wherein the device comprises two arms ( 7, 7 ′) which at first ends are pivotally arranged about a substantially horizontal axis being substantially perpendicular to the length axis of the vessel, and which axis substantially coincides with a rotational of a stern roller ( 4 ) arranged at the aft end of a cargo deck ( 2 ) of the vessel, and where the arms ( 7, 7 ′) at their second ends support an anchor handling roller ( 8 ) having an axis of rotation being substantially parallel to the axis of rotation for the arms ( 7, 7 ′), is described.
1. An anchor handling device for an anchor handling vessel, the anchor handling device bringing an anchor from a substantially horizontal position resting at an aft deck of the vessel, to a substantially vertical position hanging astern of the vessel, wherein the device comprises two arms which at first ends are pivotally arranged about a substantially horizontal axis being substantially perpendicular to the length axis of the vessel, and which substantially horizontal axis substantially coincides with a rotational axis of a stern roller arranged at the aft end of a cargo deck of the vessel, and where the arms at their second ends support an anchor handling roller having an axis of rotation being substantially parallel to the axis of rotation for the arms and wherein the arms and the anchor handling roller are rotated from a stowed away position where the arms and the anchor handling roller are arranged in channels in the cargo deck, and an active position where an aft vertical tangent of the anchor handling roller coincides or is astern of an aft vertical tangent of the stern roller.
2. The device according to claim 1 , wherein the arms are rotated by means of hydraulic actuators.
3. The device according to claim 1 , wherein the arms are fixed to a rotating shaft.
4. The device according to claim 1 , wherein the arms are rotary connected to a rotating shaft.
5. The device according to claim 4 , wherein the stern roller is rotary arranged about the rotating shaft.
