Problems solved by technology

Both types of lifting devices are fixed on the platform. After the platform is lifted into place, it will be idle for a long time. The design and manufacturing cost of the lifting device is high. If the utilization rate of the equipment cannot be improved, the comprehensive rental cost of the entire platform will increase significantly, making it impossible Low cost requirements to meet marginal field development requirements

Abstract

The invention relates to a steel strand lifting device and a lifting method. The steel strand lifting device comprises steel strand lifting device bodies, a hoisting support base, slidable moving limiting blocks, steel strands, lifting heads and connection bases. By combining the multiple sets of steel strand lifting device bodies, a platform deck can go up and down, and the installation time of the platform at sea is effectively saved. The steel strand lifting device is convenient to assemble and disassemble, capable of being reused, simple in overall structure, low in manufacturing difficulty, remarkable in integrated cost advantage, particularly suitable for exploration of marginal oil field and capable of speeding up production of the marginal oil field.

Description

technical field [0001] The invention relates to a lifting device, in particular to a steel strand lifting device, which belongs to the field of simple and small platform installation in the development of marginal oil fields. Background technique [0002] Offshore mobile platform is the most commonly used production equipment in the offshore oil industry, and has played an important role in the actual use of offshore production. General offshore mobile platforms need specially designed and manufactured special lifting devices for the lifting operation of the platform. According to the actual use forms, there are hydraulic bolt stepping lifting devices and motor-driven rack and pinion continuous lifting devices. Both types of lifting devices are fixed on the platform. After the platform is lifted into place, it will be idle for a long time. The design and manufacturing cost of the lifting device is high. If the utilization rate of the equipment cannot be improved, the compreh...
