Self-elevating ocean platform pile leg and pile shoe equipment cable take-up and pay-off system

Abstract

A self-elevating ocean platform pile leg and pile shoe equipment cable take-up and pay-off system is provided with a vertically-arranged pile leg, a self-elevating ocean platform is in sliding connection with the pile leg, an electric winch is fixed to the self-elevating ocean platform, an electric slip ring is fixed to the electric winch, one end of the electric slip ring is connected with a slip ring junction box through an adapter cable, and a junction box is fixed to the top of the pile leg. A flexible composite cable extending out of the junction box penetrates through the cable guide mechanism and is connected with the other end of the electric slip ring. According to the invention, cables connected with a plurality of electrical equipment on the pile leg and the pile shoe are gathered to form a flexible composite cable, and the flexible composite cable is connected with a cable on an ocean platform through the electric winch, so that the functions of power supply and signal transmission are realized. The flexible composite cable does not need to be released in the cable recovery or release process, the electrical continuity can be ensured, the cable cannot be twisted, human intervention is not needed, and the labor intensity is reduced. The electric winch automatically and synchronously runs along with lifting of the ocean platform, the automation degree of the system is improved, and labor intensity is reduced.

Description

technical field [0001] The invention belongs to the field of ship design and construction, and particularly relates to a method for measuring whether the lighting angle of lights during the navigation of the ship conforms to the specification after the ship is constructed. Background technique [0002] Self-elevating offshore platform is a common offshore platform structure type. When the standing piles are stable, the platform can rise or fall along the pile legs. Since the relative positions between the pile legs and the pile boots under the pile legs and the platform are not fixed, Therefore, try to avoid installing equipment on the legs and in the boots to reduce the connection of cables or pipelines between the legs and boots and the platform. However, according to the needs of the operation, aviation obstruction lights, strong lights, submersible pumps, sensors and other equipment need to be installed on the pile legs of some jack-up offshore platforms; pile punching p...

AI Technical Summary

Problems solved by technology

However, according to the needs of the operation, aviation obstruction lights, strong lights, submersible pumps, sensors and other equipment need to be installed on the legs of some jack-up offshore platforms; pile flushing pumps, sensors and other equipment need to be installed inside the spud boots. How to realize the integration of these equipment and Reliable electrical connection between platforms is a technical problem

Although the submersible pumps or anti-sea organism devices of some self-elevating offshore platforms are also installed on the legs, and the cables are retracted and unwound by the cable winches on the deck, these devices are only connected to power cables, and there are few types of cables. Small; the cable winch is hand-operated, and human intervention is required after the cable is twisted, and the workload of the operator is heavy; the operator needs to operate on site, and cannot grasp key parameters such as cable tension and release length. Only by visual inspection, once the cable breaks, May cause personal injury, there is a safety hazard

Therefore, the cable retractable design of the existing self-elevating offshore platform submersible pump or the anti-sea organism device has great limitations, is not suitable for other types of equipment, and has high labor intensity and poor safety.
