Problems solved by technology
[0004] 1) The reverse bottom of the hull on the semi-submersible platform needs to be equipped with a large number of lifting points for the main hoist to be lowered and supported. The welding and removal of the lifting points will cause more damage to the reverse bottom paint, which will affect the later production progress
[0005] 2) Closing the high supports and laying them down takes up a lot of space on the site, but the space at the bottom of the semi-submersible platform is small and there are many high supports, so the risk is greater during the process of laying down, and it is very easy to collide with other high supports or platform structures, and cross at the same time A lot of work, a big safety risk

Embodiment Construction
[0021] Such as Figure 1-2 As shown, a semi-submersible offshore platform closes high support removal method, comprising the following steps:
[0022] Step 1: According to the high-support pulling path, level the ground along the line, clean up the relevant prominent ground bars, etc., to prevent the continuity from being affected during the pulling process;
[0023] Step 2: According to the layout characteristics of the high support, use steel pipes or square pipes, steel wire ropes, etc. to connect the bottom and the upper part of the high support, and divide it into two parts to make 7 sets of supports 2 at the bow, 9 sets of supports 3 at the stern, and the front end of the lower part of the high support Lay out lugs 8, welding is used between the steel pipe or square pipe and the bottom of the high support, and the top of the high support has been connected by a walkway platform, and the whole is firmly tied and reinforced with a steel wire rope;
[0024] Step 3: Arrange...

The invention discloses a closure high support dismantling method of a semi-submersible ocean platform. The closure high support dismantling method comprises the steps that the high support is dividedinto two parts to be pulled out of the bottom of the semi-submersible platform through pulling and then is disassembled and dismantled through a gantry crane. Cross operation in the dismantling process can be reduced, safety risks are reduced, meanwhile, the influence on operation of the ocean platform is small, and the efficiency is high under the condition of sufficient preparation.
Description
technical field [0001] The invention relates to the technical field of manufacturing ships and marine engineering products, in particular to a method for removing a closed high support of a semi-submersible offshore platform. Background technique [0002] The semi-submersible offshore platform has strong wind and wave resistance, excellent motion performance, huge deck area and loading capacity, and high operating efficiency. Its structural form generally includes: an upper hull, two floating bodies and four columns, the floating body and the upper hull are connected by columns, and the left and right floating bodies are generally connected by two cross-bracing pipes. The construction methods of semi-submersible offshore platforms generally adopt several common construction and closure methods such as the overall upper hull lifting floating body sliding, the overall hoisting of the upper hull, conventional building blocks, and floating lifting of the upper hull, and the conv...
