Embodiment Construction

[0026] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of examples.

[0027] Such as figure 1 with figure 2 Shown, a kind of deck pipe bundle unit installation method of the present invention comprises the following steps:

[0028] S11. Mark the fixed position of the outrigger 1 at the installation position of the tube bundle unit on the deck. After fixing the outrigger 1 on the deck, use a bracket to connect the root of the outrigger 1 to the deck. Each outrigger 1 There are two brackets, which are arranged symmetrically, and the number of brackets can also be 3 or 4, which are evenly distributed and arranged in the circumferential direction of the leg 1;

[0029] S12. Weld the legs 1 of the tube bundle unit to the corresponding fixed position on the deck, level the top of the legs 1 uniformly, cut off the margin, and make the tops of the legs 1 on the same level;

[0030] S13 , hoi...

Abstract

The invention discloses a deck tube bundle unit mounting method. The deck tube bundle unit mounting method comprises the following steps of S11, marking fixing positions of outriggers in the mounting position of a deck upper tube bundle unit; S12, welding the outriggers of a tube bundle unit in the corresponding fixing positions on a deck, and enabling the top of each outrigger to be on the horizontal plane; and S13, hoisting a pre-assembled frame structure on the outriggers, and adjusting the position of the frame structure and fixing the frame structure on the outriggers. According to the deck tube bundle unit mounting method, during integral mounting, firstly, the lower outrigger parts are mounted in bulk after being total-assembled on a deck, and the single outrigger is more convenient to mount and locate, and secondly, the pre-made frame structure is mounted; and therefore, the accuracy of the whole unit during making is guaranteed. By making the upper frame structure on a steel structure platform in advance, the making is convenient, a special bed-jig is not needed, controllable mounting accuracy of the whole tube bundle unit is guaranteed, and the follow-up mounting time is saved.

Description

technical field [0001] The invention relates to a method for installing a deck tube bundle unit. Background technique [0002] Offshore Floating Production Storage Vessel (FPSO) is a comprehensive large-scale offshore vessel that separates extracted oil from oil and gas, treats oily sewage, power generation, heat supply, storage and transportation of crude oil products, and integrates personnel living and production command systems. Oil production base. Compared with other forms of oil production platforms, FPSO has the advantages of strong wind and wave resistance, wide water depth range, large oil storage / unloading capacity, transferability and repeated use, and is widely suitable for deep sea, shallow sea and marginal oil fields far from the coast The development of offshore oil and gas fields has become the mainstream production method for offshore oil and gas field development. [0003] The deck tube bundle unit of FPSO ship is relatively complex, including 15 systems...
