Through a model experiment study of a 175 000dwt bulk carrier and a 110 000dwt oil tanker, subject to external forces (wind, current and wave), side-by-side moored at berth, some regular patterns of mooring cable and fender forces changing with the environmental conditions are derived under the conditions that the wind blows towards and from the shore.

China s engineers generally use a two-dimensional mathematical model of the airborne sonar-cable dynamic system.

That the cable keeps some touching arc with driving wheel of drugging cable machine can decrease the spring force and the Driving power.
