The invention relates to a cable stranding system with an auxiliary ship for implementing a semi-submersible transport ship and an unloading method thereof. The cable stranding system comprises the semi-submersible transport ship, the auxiliary ship and a towing ship, the auxiliary ship and the towing ship are both arranged opposite to the semi-submersible transport ship, the semi-submersible transport ship and the auxiliary ship are each provided with a winch, and a first mooring rope is wound around the winch on the auxiliary ship; after the connection between the semi-submersible transportship and the cargo body is completely cut off, the semi-submersible transport ship starts to dive, and the cargo body is completely separated from the semi-submersible transport ship under the actionof buoyancy of the cargo body; a second mooring rope of a winch on the semi-submersible transport ship starts to be taken up and paid off, and the cargo body is slowly twisted to the broadside limit position of the semi-submersible transport ship; removing a second cable of a winch on the semi-submersible transport ship, pulling the cargo body out of the safety area at a constant speed through a first cable on the auxiliary ship, and enabling a cable on the tugboat to be in a semi-tensioned auxiliary state; the stability, the safety and the reliability of the device can be greatly improved, and the risk of floating unloading operation is effectively reduced.

    本发明涉及一种带辅助船实施半潜运输船的绞缆系统及其卸货方法,包括半潜运输船、辅助船和拖轮船,辅助船和拖轮船均与半潜运输船相对设置,半潜运输船和辅助船上均设有绞缆机,辅助船上的绞缆机上绕设有第一缆绳;将半潜运输船与货物本体之间的连接完全切断后,半潜运输船开始下潜,货物本体在自身浮力作用下与半潜运输船完全脱离;半潜运输船上的绞缆机的第二缆绳开始收放,将货物本体缓慢绞至半潜运输船的舷边极限位置;解除半潜运输船上的绞缆机的第二缆绳,通过辅助船上的第一缆绳匀速将货物本体拉出安全区域,其间拖轮船上的缆绳处于半拉紧的辅助状态;有利于大幅提高自身的稳定性、安全性和可靠性,有效地降低了浮卸作业的风险。
