Flare boom prefabrication, trial-assembly and shipment process

Abstract

The invention discloses a flare boom prefabrication, trial-assembly and shipment process which comprises the following steps of laterally building a flare boom, and prefabricating and installing accessory structures at low positions; when hoisting the flare boom, turning over the flare boom by 90 degrees to a flat lying state so as to meet a trial-assembly working condition; after finishing the trial assembly of the flare boom, directly locating on shipment supports on a prefabrication site; welding shipment support top beams, fixing the shipment supports and the flare boom, and using invertedchains for fixing the flare boom so as to prevent the flare boom from toppling and falling; after a transport ship is in place, simultaneously hoisting through the flare boom and the shipment supports, and locating on a ship deck position; and welding the shipment supports and the transport ship deck, so that the flare boom shipment and transportation demands are met. According to the process provided by the invention, the hoisting time is greatly shortened, the resource utilization rate and the safety are improved, the construction can be carried out conveniently and simply, the constructionperiod is saved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to the field of offshore petroleum engineering, and is especially applicable to the torch arm of an offshore platform that requires land trial installation, and is applied in the field of offshore petroleum engineering. Background technique [0002] Part of the torch arm of the offshore oil platform needs to be installed at sea and tested on land. At present, part of the flare booms of offshore oil and gas platforms need to be installed on land and then transported by transport ships to the sea for formal installation. During prefabrication, the torch boom adopts more positive fabrication methods, and the auxiliary structural parts such as inclined ladders need to be built at a high level, scaffolding, etc. are erected, and there are many high-altitude operations; at the same time, when the torch boom is loaded, the ship support is first welded on the hull deck, and then the torch boom is hoisted. Due to the accuracy, the shippin...

AI Technical Summary

Problems solved by technology

The problems of this process are as follows: 1. Prefabrication, inclined ladders and other auxiliary structures need to be built at a high level, and a large number of scaffoldings need to be erected, and there are many high-altitude operations; 2. The loading support is first welded to the hull deck, and then the torch arm is hoisted in place Due to construction accuracy and other reasons, when the torch arm is loaded and hoisted in place, there will be a certain collision with the welded ship support. The ship support needs to be re-welded and fixed according to the torch arm. During the entire adjustment period, the crane needs to wait for adjustment Completed, the crane takes a long time, and the construction risk is high
