Problems solved by technology

When the hoisting weight of the offshore platform module exceeds the capacity of the floating crane, or it is necessary to seek offshore floating crane resources with greater capacity, it is difficult to lock the floating crane resources and pay more funds; even if there are no floating crane resources available, the plan is not feasible

Abstract

The invention relates to a connecting device for the separate hoisting of large offshore platform modules, which comprises a main supporting device body and stabbing cone devices, the main supporting device body comprises main-axis structural beams, transverse stay bars are fixed between the two main-axis structural beams, and horizontal oblique stay bars are fixed in the rectangular frames formed between the transverse stay bars and the main-axis structural beams; main module uprights are fixed at the joints between the main-axis structural beams and the transverse stay bars, and a working deck is arranged at a middle position between the main module uprights; side oblique stay bars are arranged in the space formed between each main-axis structural beam and each two neighboring main module uprights, the ends of the side oblique stay bars, which are connected, are fixed on the main-axis structural beam, and the other ends of the side oblique stay bars are respectively fixed on the bottom of each main module upright; supporting legs are also arranged between the main-axis structural beams and the side oblique stay bars, and the stabbing cone devices are arranged on the top ends of the main module uprights and the supporting legs. The connecting device can be widely applied in the field of offshore oil and gas fields.

Description

technical field [0001] The invention relates to a connection device in the field of offshore oil and gas fields, in particular to a connection device used for block-by-block hoisting of large offshore platform blocks. Background technique [0002] With the advancement of the rolling development of my country's offshore oil and gas fields, the development of offshore oil and gas fields has gradually increased from a water depth of 50 meters to 100 to 300 meters in recent years. For large-scale offshore central processing platforms, their functions continue to increase, the equipment increases, and the block area continues to increase, resulting in continuous breakthroughs in the weight of offshore platform blocks. When the offshore platform module is constructed with a hoisting scheme, the selection of offshore floating cranes is a key part of offshore oil and gas development. Large-scale offshore floating cranes are a scarce resource. The greater the lifting capacity, the f...
