Title:
【発明の名称】能動力反動システム及び受動減衰を有する係船システム
Document Type and Number:
Japanese Patent JP2003520725
Kind Code:
A
Abstract:
A mooring system including a body/arm/vessel arrangement with passive damping and/or an active force restoring system. The active force restoring system includes a sensor for generating a displacement signal representative of the displacement of the vessel from a quiescent position and an active forcing device which responds to the displacement signal to force the arm in a direction to move the vessel toward the quiescent position. The passive damping arrangement includes a device, independent of and in addition to the damping of the water on the vessel or the arm, that damps the oscillation of the vessel in response to environmental conditions which force the vessel from its quiescent position. Hydraulic cylinder arrangements are provided for active forcing and passive damping. Powered winch/cable arrangements are also provided for active force systems. Alternative devices for active and passive damping systems of torque actuators include hydraulic powered cans with internal fins, or cans with internal elastomeric elements or disk brake elements.
