Problems solved by technology
However, due to the great difference between the environmental conditions in the laboratory and the actual marine environmental conditions, there are certain inaccuracies in the experimental data and actual application tests, which leads to the development of new products that cannot meet the requirements of the real marine environment. The risk of demand not only cannot completely and accurately guide the development of various new marine engineering products and complete the actual application test of new products, but also wastes test time, increases test costs, and delays the development of new products, affecting my country's marine engineering. industry development

Embodiment Construction
[0027] Such as figure 1 As shown, firstly, the jacket 2 for the test is built on land, and the jacket 2 for the test is transported to the pier 9 for installation. The specific installation steps are as follows:
[0028] The first step: if figure 2 As shown, the support frame 1 is arranged on the pier 9;
[0029] The second step: if image 3 As shown, several anti-collision parts 3 are installed on the lower side of the test jacket 2 by means of bolt connection;
[0030] Step 3: If Figure 4 As shown, one end of the cable 4 is permanently fixed to the upper end of the test jacket 2 by bundling or shackle connection, and the other end of the cable 4 is also temporarily fixed to the test jacket by bundling or shackle connection. 2 is attached to the structure 5;
[0031] Step 4: If Figure 5 As shown, the jacket 2 for the test is hoisted and positioned at the set position by the sling 8 hung on the crane;
[0032] Step 5: If Figure 6 As shown, a counterweight 6 is plac...

The invention provides a process for installing a guide pipe rack for experiments at a wharf. The method comprises the following installation steps: 1, installing a supporting frame on the wharf; 2, installing a plurality of anticollision pieces at one side of the lower part of the guide pipe rack for experiments; 3, fixing one end of a rope at the upper part of the guide pipe rack for experiments, and temporarily fixing the other end of the rope on a hanging structure of the guide pipe rack for experiments; 4, hoisting and positioning the guide pipe rack for experiments in a set position; 5, placing a clump weight on the hanging rack of the guide pipe rack for experiments, and hanging the hanging structure on the edge of the wharf; 6, tying the temporarily fixed rope on a rope tying pile, fastening, and then removing the lifting rope and a hoist. The process provided by the invention can be used for hanging the guide pipe rack for experiments on the wharf, not only enabling a test environment and a real application environment to be consistent, improving the accuracy of various experimental data and the practical application testing reliability of new products, furthermore overcoming the defect of higher marine installation cost of the guide pipe rack for experiments and lowering the marine installation cost and experimental cost of the guide pipe rack for experiments.
Description
technical field [0001] The invention relates to a jacket installation process, in particular to a wharf installation process for a test jacket, belonging to the field of offshore oil engineering. Background technique [0002] The progress of the marine engineering industry relies on the continuous research and development of various new marine engineering products, and the research and development of new products and practical application tests need to be completed on the jacket in a complex marine environment. The offshore installation and fixing of the jacket is carried out in the process, and the engineering quantity is relatively large; moreover, due to factors such as high cost and difficulty of offshore installation, fixing and actual testing, long cycle and inconvenient dismantling, the cost of offshore testing is relatively high. [0003] In order to change the above-mentioned shortcomings of installing a jacket for testing at sea, the usual practice is to conduct va...
