Device and method for laying and recycling cables

Abstract

The invention relates to a device and a method for laying and recycling cables. The device comprises a floating drum, a steel cable and a suspension component. A cable storage disc is arranged on the upper portion of the floating drum, and a cable outlet pipeline is arranged in the floating drum. One end of the steel cable is wound and fixed to the cable storage disc, the other end of the steel cable penetrates through the cable outlet pipeline and is fixedly connected with the suspension component, a locating component is fixedly connected to the outer wall of the middle of the suspension component, the locating component is connected with the steel cable, and the suspension component clamps the cable and fixes the cable in a through hole. The method comprises the steps that the initial distance between the suspension component and a device platform is determined according to a catenary analytical calculation formula; a crane places the floating drum, the suspension component and the cable into water at the position with the initial distance away from the device platform; a cable laying ship carries out line navigation at a low speed in the direction away from device platform; a cable winch releases cables continuously along with moving of the cable laying ship. The device and method can lay cables rapidly and conveniently, can recycle cables effectively for reutilization, cost is lowered greatly, and economic performance is improved greatly.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a device and method for laying and recovering cables. Background technique [0002] As ocean development projects move from shallow seas to deep seas, the difficulty of laying cables for deep-water equipment also increases. To be able to work underwater, deep-water equipment needs cables to transmit data signals and power signals. The speed and convenience of cable laying and recovery Greatly affected the working conditions of deepwater equipment. [0003] There are two commonly used cable laying methods. The first method: laying the cables at the bottom of the water and burying them in the mud layer, because this method needs to work and lay the cables underwater, which leads to a large workload and high process requirements, and the cables cannot be recycled, resulting in higher cost. The second method: use a lot of water surface buoys to fix on the cable at inter...
