Embodiment 1

[0037] The embodiment of the present invention provides a bottom-mounted platform off-bottom test device, the test device is used for on-board test of offshore engineering geological survey, and needs to be used in conjunction with a seabed surface sampling device. The commonly used subsea surface sampling device is the box sampler, which is one of the main tools for subsea surface sampling. The box-type sampler is made of sturdy metal material, and the top surface soil sample is obtained and placed on the survey ship. The upper opening is generally square. The seated platform off-bottom test device of this embodiment is used in conjunction with a box-type sampler.

[0038] see figure 1 and figure 2, the seated platform off-bottom test device of the present embodiment as a whole includes a bracket part 9, a loading part, a probe part and a measuring part, and the detailed structures of the above components are as follows:

[0039] The bracket part 9 is used for connecting ...

Abstract

The invention discloses a seated platform off-bottom test device and a test method. The test device includes a bracket part, a loading part, a probe part and a measurement part. The loading part and the probe part are used to perform a seated platform off-bottom test. Loading The part is connected with the probe part, which is used to simulate the off-bottom drive of the seated platform; the probe part is used to simulate the seated platform, and the probe part includes connectors and several metal plates with adjustable angles, which can simulate the seated platform in the off-bottom. Different angles and attitudes in the bottom process, so that the whole test process is closer to the real bottoming process of the seated platform; the measurement part is used to detect the parameters in the test process. The invention can realize the field test analysis of the adsorption force of the seabed silt soil, replaces the indoor model test, the test device has a simple structure, is easy to operate, can carry out on-site sampling analysis, greatly reduces the workload of the test, and the soil samples used in the field test are For on-site acquisition, the test data is more reliable.

Description

technical field [0001] The present application belongs to the technical field of marine engineering geological testing, and in particular relates to an off-bottom test device and a test method for a sitting-bottom platform. Background technique [0002] Offshore mobile platforms include jack-up plug-in platforms and bottom-mounted platforms. When the self-elevating pile-inserting platform is in place, insert the legs of the pile several meters to a dozen meters below the mud surface, which is completely submerged; when the bottom-mounted platform is in place, it sits directly on the seabed, and the depth of the mud is usually no more than 1m. Partially submerged. When the platform is off the bottom, the self-elevating pile-insertion platform needs to be pulled out of the pile, and the bottom-mounted platform needs to be lifted off the bottom. The foundation forms of the two mobile platforms are different. The self-elevating pile-insertion platform is a round tube type pile...
