Abstract

The invention discloses an energy-saving type floatable ocean platform movement control device, comprising a self-energized magneto-rheological controller, a bracket, a connection stand column, and a rigid fixing end. The magneto-rheological controller supplied with energy by a storage battery comprises a cylinder body, a pressing end cover, magneto-rheological liquid, a piston, a coil, a damping channel, a coil lead wire, a self-energy supplying device, a floating piston and an end cover. By pre-setting current strength in the storage battery of the self-energy supplying device, the movement control device outputs different control forces, so that the movement altitude of a floatable ocean platform is reduced; the operation condition is improved; and the operation efficiency is improved.

Description

technical field [0001] The invention relates to an energy-saving motion control device suitable for floating ocean platforms, belonging to the field of motion control of ocean platforms. Background technique [0002] With the increasing demand of human beings for oil and gas resources and the gradual depletion of onshore oil and gas resources, the development of offshore oil and gas resources is getting more and more attention from all countries. As the basic facilities for the development of offshore oil and gas resources, the number of offshore platforms is increasing rapidly. At present, there are more than 8,000 offshore platforms in use at home and abroad, including more than 7,000 fixed platforms and nearly 1,000 floating platforms. These offshore platforms are huge in size, complex in structure, and expensive in cost. Especially compared with land structures, the marine environment they live in is very complex and harsh. Disasters such as wind, waves, currents, sea i...
