AI Technical Summary

Technical Problem

Existing offshore oil and gas drilling floating platforms are susceptible to damage from ice impacts in extreme ice environments. Ice blocks can also impact drilling equipment, affecting the normal progress of drilling operations, increasing maintenance costs and extending drilling time. In addition, the platforms have poor stability and are at risk of capsizing.

Method used

A floating platform including an ice-breaking mechanism was designed. The ice-breaking mechanism consists of an ice impact plate, ice blades, a drive motor, and a cam. By precisely controlling the movement trajectory of the ice blades, using the buoyancy chamber to provide buoyancy and column stability, and combining the traction rope to adjust the platform's balance, precise ice breaking is achieved and structural damage is reduced.

Benefits of technology

It enables precise icebreaking in extreme ice environments, reduces damage to platform structures, improves the stability and efficiency of drilling operations, lowers maintenance costs, and ensures the platform remains balanced and stable under extreme sea conditions.

Abstract

This invention provides a floating platform for offshore oil and gas drilling in polar ice regions, comprising a platform module and an icebreaking mechanism. The icebreaking mechanism is located below the platform module and includes an ice impact plate, ice blades, a drive motor, and a cam. The ice impact plate is rotatably connected to the platform module. Multiple ice blades are evenly spaced on the ice impact plate. The drive motor is mounted on the platform module, and the cam is fixed on the output shaft of the drive motor. The cam is rotatably connected to the ice impact plate via a transmission rod. In this invention, the movement trajectory of the ice blades matches the contour line of the cam, enabling precise icebreaking. The shape and movement of the cam can be precisely controlled, allowing the ice blades to move and break ice along a preset path. This achieves more precise icebreaking results, reduces the impact force of ice on the platform module, and lowers the risk of structural damage.
