A kind of prefabrication, trial assembly and ship loading process of flare arm

Abstract

The invention discloses a process of prefabrication, trial assembly and ship loading of a torch arm, which comprises the following steps: lateral construction of the torch arm, low-level prefabrication and installation of the auxiliary structure; Satisfy the trial installation conditions; after the trial installation of the torch arm is completed, it is directly located on the ship loading support of the prefabricated site; the top beam of the ship loading support is welded to fix the ship support and the torch arm, and the torch arm is fixed by an inverted chain to prevent it from toppling over; After the transport ship is in place, the torch arm and the shipping support are hoisted at the same time and placed on the deck of the ship; the shipping support is welded to the deck of the transport ship to meet the loading and transportation needs of the torch arm. The technology of the invention greatly shortens the hoisting time, improves resource utilization and safety, is convenient and simple in construction, saves construction period and reduces construction cost.

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
