METHOD OF MOORING A FLOATING STRUCTURE USING GRAVITY MOORING

摘要

The present invention relates to a mooring method using a gravity-type mooring device of a floating structure capable of controlling tensile by having at least four gravity-type mooring devices provided in a floating structure and unwinding a support rope in accordance with movements of a floating structure, wherein the gravity-type mooring device includes a support rope having one end fixed to a bottom in water and the other end connected with a weight while being guided by a tensile control unit, a gradient sensor, a tensile sensor, and a satellite navigation device. The mooring method using a gravity-type mooring device of a floating structure includes: a step of confirming the gradient change in the slope sensor of the corresponding gravity-type mooring device when a tensile state of the support rope is out of a predetermined range and unwinding a support rope when a gradient change is detected; a step of confirming changes in tensile values of the support ropes in the tensile sensor again when a change in the gradient of the floating structure is not generated, and unwinding all support ropes when the tensile of all support ropes are greater than a predetermined range; and a step of confirming a change in azimuth of the floating structure in a satellite navigation device when tensile of the support ropes is less than a predetermined range and unwinding all support ropes when a change in azimuth of a floating structure is not generated.
