A CONTRIBUTION TO THE ANCHORING PROBLEMS OF SHIPS IN THE OPEN SEA

The motions of floating rigs while anchoring in unsheltered waters is discussed. A taut anchoring system, using heavy synthetic fibre ropes and a special anchor piling set by hydrostatic pressure is introduced and discussed. For the system described in this paper, a calculation method is presented which computes the stresses on the components while exposed to reactions of the rig to wind, current and waves. Results, based on this procedure, show that the properly designed system allows for the unavoidable heave and surge motions within the working elasticity of the ropes, although they may be prestressed at the same time by current and wind forces.
