Abstract

The invention relates to a deep sea multi-column mooring floating platform vortex-induced motion pool test device. The device comprises a trailer, a longitudinal motion guide rail mechanism, a transverse motion guide rail mechanism, a yawing rotation mechanism, an optical measurement mechanism and a top plate for mounting a floating platform model; a longitudinal elastic piece for determining thelongitudinal rigidity is further arranged between the trailer and the transverse motion guide rail mechanism; a transverse elastic piece for determining the transverse rigidity is further arranged between the transverse motion guide rail mechanism and the yawing rotation mechanism, and an elastic restraining piece for determining the rotating rigidity is further arranged between a yawing rotatingsupport and a connecting main shaft. Compared with the prior art, the test device not only can accurately and equivalently simulate the three-degree-of-freedom rigidity of a mooring system in the horizontal plane under the actual sea condition, but also can simulate the vortex-induced motion response characteristic of a deep sea platform under the nonlinear rigidity equivalent constraint.

Description

technical field [0001] The invention belongs to the technical field of vortex-induced motion pool tests on ocean platforms, and relates to a deep-sea multi-column mooring floating platform vortex-induced motion pool test device. Background technique [0002] In recent years, with the development of offshore oil and gas resources shifting from shallow sea to deep sea, the multi-column moored floating platform has developed rapidly and has become one of the high-tech equipment for marine engineering today, which mainly includes semi-submersible platforms and tension leg platforms. . This type of platform is not only economical in cost and easy to install, but also has many advantages such as large payload and strong later expansion performance. At present, about 70% of deep-sea oil and gas development in the world uses multi-pillar floating platforms. With my country's further development in the field of oil and gas resources development in the South China Sea, the demand for...
