Abstract:
A locking device (1) for temporarily locking of a rope, the locking device comprising two rods (2, 2a) at a distance greater than the diameter of the rope, the rods (2, 2a) being arranged about an origin of a turntable (4) so that a rope being arranged between the rods (2, 2a) is turned about the rods (2, 2a) as the turntable (4) is rotated, wherein each rod (2, 2a) form an acute angle with the plane of the turntable (4), is described.
Abstract:
A gripping tool for a crane or the like, comprising a bracket (2) for connecting the tool to the crane or the like, a main body (6) connected to the bracket (2), where jaw parts (10, 11) are pivotally arranged on the main body 6, where the jaw parts (10, 11) are controlled by actuators (12) and where the jaw parts (10, 11) are arranged so that they may cooperatively grip and hold goods to be lifted or manipulated, wherein an supplementary jaw member (15) is displaceably arranged on one of the jaw parts (10) can be displaced from a position where a gripping surface (16) on the supplementary jaw member (15) rests against a gripping surface (17) of the outer surface of the jaw member (10), to a position where the gripping surface (16) has a distance to the gripping surface (17) of the jaw member, and where the displacement of gripping surface (16) is a substantially parallel displacement, is decribed.
Abstract:
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 decribed.
Abstract:
A method and device for temporarily coupling of a hose to a pipe system, where a first coupling part is connected to the hose, and a second coupling part is connected to the pipe system, where both the first and the second coupling part comprises valves that automatically closes when said first and second coupling parts are not connected to each other, wherein said first and second coupling part are brought into interaction with each other to establish a tight connection before the valves in the coupling parts are opened and where the coupling parts are locked to each other.
Abstract:
A method for temporary or permanent stopping of an elongated body where a sleeve of cables is braided around the elongated body and that the cables are held so that the sleeve is tightened around the elongated body by the force pulling the elongated body. A device for carrying out the method is also described.
Abstract:
A rope handling system for an offshore vessel for handling of synthetic rope (3) for heavy lifting and deployment operations offshore, the system comprising multiple winch drums (11) adopted for housing a predetermined length of rope (3), a spooling system (13, 17) to spool in and spool out rope on the drums (11), a transfer system comprising of sheaves (14, 21, 22) for leading the rope (3) between a drum (11) and a traction winch (15), the traction winch (15) comprising three or more sheaves (30), where the sheaves are arranged so that rope may be arranged from one sheave to the next substantially following a common tangent of the two sheaves and so that the rope rests against about half the circumference of each sheave, and where each sheave operated by an independent motor (32), and where a rope stopper (4) is arranged downstream of the traction winch relative to the drum (11) upstream of the traction winch, is described. A method for handling rope during heavy lifting and deployment operations, and a method for loading rope onto the system are also described.
Abstract:
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 decribed.
Abstract:
A locking device for temporary locking and securing of a chain, cable or wire, comprising a fork shaped main body (5) comprising two teeth (6) where clamps (7) extending from the teeth (6) towards each other, the clamps having substantially vertically arranged edges (7') facing each other and defining a substantially vertical gap (10) between the edges (7'), where the distance between the clamps being adapted to the diameter of a chain link or cable or a wire so that it may pass into the gap, but where a next chain link of a chain or a clamp on a cable or wire, is stopped against the clamps to lock or secure the chain, cable or wire, wherein the locking inserts are substantially linear and horizontally displaceable for adjustment of the gap (10) between the clamps (7) according to the diameter of the cable, wire or chain link, is described.
Abstract:
A method putting out an anchor from a deck of a vessel and for taking onboard an anchor from the sea, wherein a displaceable resting surface for supporting the anchor is provided. The resting surface may be displaced from a substantially horizontal position to a substantially vertical position to simplify and to avoid damage on vessel and equipment during anchor handling operations. A device for realization of the method is also described.
