Abstract

The present invention discloses a method for carrying out a load test on equipment. The method is used for a floating type offshore platform, and comprises: calculating the amount of water to be injected into a barge and the draught depth of a floating type offshore platform during a test according to the actual demand of equipment to be tested; injecting ballast water calculated in the previous step to make the barge achieve a certain draught depth, and moving the barge to a position between two floats of the floating type offshore platform and positioned below the equipment to be tested; placing or suspending a balance beam with a rigging on the equipment to be tested, and connecting the rigging to the barge; and gradually discharging the ballast water of the floating type offshore platform to make the floating type offshore platform rise and drive the barge to rise so as to reduce the draught depth of the barge, entering a load test state when the barge rises to achieve a required height, maintaining the barge at the required height for a certain time, and observing whether the equipment to be tested is deformed. The method of the invention has advantages of convenient operation and high safety.

Description

technical field

[0001] The invention relates to the field of marine engineering equipment, in particular to a load test method for casing tensioners, trolleys, top drives and other equipment of floating drilling platforms. Background technique

[0002] In the field of offshore engineering, there are a large number of drilling-related equipment that need to be subjected to load tests, but some of the equipment is located below the drill floor, and there is no way to use the commonly used load test methods. The equipment load test in the traditional sense is to gradually increase the weight on the equipment to the test load to achieve the purpose of the load test. For example, the load test is carried out by hanging a water bag under the equipment and then filling the water bag with water. The cost of the method is high, and the water is filled in the water bag in the air, and the operation procedure is very complicated.

Embodiment Construction

[0022] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0023] In the field of ocean engineering, the equipment configured on the floating offshore platform (for example, semi-submersible floating drilling platform), such as trolleys, casing tensioners, top drives, etc., must be subjected to load tests to evaluate the In the case of preset load, whether the performance is stable. The present invention proposes a method of equipment load test aimed at the floating offshore platform. The present invention cleverly utilizes the ballast water system of the floating offshore platform itself, and uses the buoyancy of the floating offshore platform to reverse the load to achieve the load. The effect of the test.
