Modular winch

Abstract

A modular winch comprises a container framework, a winch body arranged in the middle of the container framework, and a cable arranger arranged at the front end of the container framework. The winch body comprises two side plates and an inner cylinder arranged between the two side plates. The two side plates extend outwards from the interior of the container framework. The portions, extending out of the container framework, of the two side plates can be folded towards the inner side or the outer side of the winch body. The cable capacity of the modular winch is improved without changing the size of the container framework.

Description

technical field [0001] The invention relates to a winch, in particular to a modular winch. Background technique [0002] The cable winch is an important part of the offshore tow cable collection equipment, which plays the role of storing and retracting the underwater tow cable. At present, on most offshore exploration ships, the cable winch is directly fixed and installed on the ship as a professional equipment. Some ships adopt a modular scheme, and the cable winch is made into the size of a container. Due to the size limitation, after calculation, the cable with a diameter of 56mm, the maximum cable capacity of a container winch with a standard high cabinet size is 1.8km; while at present, in the acquisition of offshore towlines, a single-cable 6km cable is often used for two-dimensional acquisition, and a single-cable 6km cable is often used for three-dimensional acquisition. Using the operation method of 4 cables and 3km cables, the cable capacity of the standard contai...

Problems solved by technology

At present, on most offshore exploration ships, the cable winch is directly fixed and installed on the ship as a professional equipment. Some ships adopt a modular scheme, and the cable winch is made into the size of a container. Due to the size limitation, after calculation, the cable with a diameter of 56mm, the maximum cable capacity of a container winch with a standard high cabinet size is 1.8km; while at present, in the acquisition of offshore towlines, a single-cable 6km cable is often used for two-dimensional acquisition, and a single-cable 6km cable is often used for three-dimensional acquisition. Using the operation method of 4 cables and 3km cables, the cable capacity of the standard container-sized cable winches is far from enough, and it can only be completed by increasing the number of winches, which brings higher costs and complicated construction difficulties.
