Abstract

The invention provides a test system and a test method for damage of a trawl plate accident to a submarine pipeline. The system comprises a pipeline model, a trawl plate model, a control system, an adjusting system, a power system and a measuring system, wherein the power system and the measuring system are connected with the control system; the pipeline model is located in the test tank, and the trawl plate model is located in the test tank and connected with the power system; the power system is arranged at the top of the test tank and used for driving the trawl plate model to move; the adjusting system is arranged on the trawl plate model and / or the pipeline model and used for adjusting the relative position between the trawl plate model and the pipeline model so that accidents can happen when the trawl plate model moves relative to the pipeline model. The measuring system is used for acquiring test data when an accident occurs; the control system is used for sending a control instruction to the power system. Different types, different accident types, different relative positions and the like between the trawl plate model and the pipeline model can be tested, and the test range is wide; assembly and disassembly are convenient; and the test efficiency and accuracy can be improved.

Description

technical field [0001] This paper relates to the technical field of offshore oil and gas engineering, especially a test system and test method for damage to submarine pipelines caused by trawl plate accidents. Background technique [0002] The 21st century is the century of the ocean. The ocean is a new and important resource space for human development in the new century. Accelerating the development of the ocean has become the consensus of various maritime countries. The development technology of traditional marine resources represented by oil and natural gas has been continuously improved and further expanded, and new marine resources such as natural gas hydrate and seabed mineral deposits have also attracted more and more attention of engineering developers. In marine resource development technology, submarine pipelines play an irreplaceable role, which provides basic conditions for ensuring economic benefits and continuous engineering development. [0003] However, the...
