Problems solved by technology

[0002] After retrieving relevant patent documents, no mooring positioning device for offshore drilling platforms with the same structure as the present invention has been retrieved. The existing mooring positioning devices for drilling platforms used for oil exploration on the ocean generally adopt multiple mooring winches. The method of independent control to stabilize the positioning of the drilling platform has played a great role in the positioning of the drilling platform, but due to the strong wind and waves in offshore operations, it is difficult to balance the force on the cable of a single mooring winch, thus The stability of the offshore drilling platform causes great danger, so it is necessary to improve the existing technology to better meet the needs of ocean operations

Abstract

The invention relates to a mooring and positioning device for an offshore drilling platform, which comprises a central controller, at least one mooring and positioning winch and a separating control device, wherein the central controller collectively controls working conditions of each mooring and positioning winch, the separating control device is respectively connected with the central controller and the each mooring and positioning winch, and the mooring and positioning winch is a water-cooled mooring winch with variable frequency resistance. Because a plurality of mooring and positioning winches are used for positioning, and a computer performs central control treatment, a cable of each mooring and positioning winch is in constant tension condition; because the mooring and positioning winch is designed into a multi-braking structural style, the diameter of a brake wheel is reduced, and space occupied by the winch on the platform is reduced; because a water cooled brake is provided, components are cooled in time, and service life of the components is prolonged; and because a wound roll is designed into a structure with a step rope guiding groove, stress condition of the cable is changed during winding, and abrasion of a wire cable is reduced.

Description

technical field [0001] The invention relates to positioning equipment on an offshore oil exploration drilling platform, in particular to a mooring positioning device for an offshore drilling platform. Background technique [0002] After retrieving relevant patent documents, no mooring positioning device for offshore drilling platforms with the same structure as the present invention has been retrieved. The existing mooring positioning devices for drilling platforms used for oil exploration on the ocean generally adopt multiple mooring winches. The method of independent control to stabilize the positioning of the drilling platform has played a great role in the positioning of the drilling platform, but due to the strong wind and waves in offshore operations, it is difficult to balance the force on the cable of a single mooring winch, thus The stability of the offshore drilling platform causes great danger, so it is necessary to improve the existing technology to better adapt ...
