Abstract
A method for the maneuvering of a vessel, such as a dredge, stacker, barge or wet concentrator plant, the vessel having provided thereon at least four winches from which winch ropes extend to anchor points located remotely from the vessel, the winches being operable to maneuver the vessel, wherein at least one winch is kept under a defined torque whilst three winches are utilized to control the movement of the vessel. A maneuvering control system for implementing the method of maneuvering described is also disclosed.
Claims33
A method for maneuvering a vessel, the vessel having at least four winches from which winch ropes extend to corresponding anchor points located remotely from the vessel, the method comprising:
- operating at least one winch to create a defined torque on the winch rope between the vessel and the corresponding anchor point which is at or near the lowest torque value that achieves a low potential energy while maintaining that winch rope in a responsive state,
- utilizing the other winches to control a movement of the vessel, and providing a redundant winch identifier for determining which winch or winches are redundant and should not be utilized to achieve the movement of the vessel,
- wherein the vessel is maneuvered in accordance with a preferred trajectory for the vessel.
