Abstract

The invention relates to a test device for an ocean platform mooring auxiliary power positioning model, which belongs to the technical field of ocean engineering, wherein a movement control module is respectively connected with a mooring mechanism and a thrustor and outputs a movement control signal; the movement control module is connected with a computer; the mooring mechanism is fixed on an ocean platform model; the thrustor is arranged in the ocean platform model; a strain foil is respectively connected with a strain amplifier and the mooring mechanism; the strain amplifier is connected with a data collection and analysis module which is respectively connected with the computer and a non-contact optical measurer; the non-contact optical measurer is arranged on the ocean platform model. The invention can make a platform system accurately positioned with lower environment load through a mooring positioning system, and save the power consumption. When the environment load is increased, the thrustor can be started for positioning so that accurate positioning can be realized.

Description

technical field [0001] The present invention relates to a device in the technical field of marine engineering, in particular to a model testing device for mooring auxiliary dynamic positioning of an ocean platform. Background technique [0002] In order to meet the needs of drilling and other engineering operations under the harsh environmental conditions of the deep sea, it is necessary to accurately maintain the position of the semi-submersible platform on the sea surface for a long period of time, but the movement of the semi-submersible platform in the horizontal plane has no recovery function. This requires the installation of a positioning system to balance the external forces acting on the floating body and reduce the horizontal movement of the floating body to reduce the displacement of its horizontal plane. The traditional positioning method is mooring positioning, which is widely used because of its simple structure, small investment, energy saving, and easy operat...
