Embodiment

[0065] The present invention is a device for measuring the force of the external environment by a dynamic positioning system. The device of the present invention can be applied to marine environment measurement ships implementing dynamic positioning, deep-sea pipeline laying ships, marine oil and gas exploration, drilling platforms and other fields. The present invention will be described in detail below.

[0066] see figure 1 As shown, the device of the present invention is a force sensor box, and the measuring method of the force sensor box comprises the steps:

[0067] Step 1: When the ship installed with this device is performing dynamic positioning, the real-time measurement values ​​of the force sensors on the front and rear sides of the force sensor box will provide the necessary measurement signals for correcting the environmental force from the longitudinal direction of the ship. The real-time measurements of the sensors will provide the necessary measurement signals ...

Abstract

The invention relates to a method for measuring external environmental force of a power positioning system. The method comprises the following steps: (1) mounting a hexahedral force sensor box on a ship, wherein force sensors on the front and rear surfaces of the force sensor box are used for measuring a signal used for correcting longitudinal environmental force of the ship in real time, and force sensors on the left and right surfaces of the force sensor box are used for measuring a signal used for correcting transverse environmental force of the ship in real time; (2) inputting the measurement values of the force sensors into an improved low-frequency ship motion model so as to finish the whole power positioning system. Compared with the prior art, the method has the purpose of finishing power positioning without specific devices for measuring wind, current, wave and the like.

Description

technical field [0001] The invention relates to technical fields such as ships implementing dynamic positioning or deep-sea oil and gas exploration and exploitation platforms, and in particular relates to a method for measuring external environment forces of a dynamic positioning system. Background technique [0002] With the increasing dependence of human beings on oil and gas resources and the depletion of land oil and gas resources, human beings have stepped up the development of marine resources. More and more shallow sea oil and gas resources have been developed, and the exploitation of deep sea oil and gas resources has become an urgent strategy for various countries. Therefore, mastering deep-sea oil and gas exploration technology has become the top priority of each country's strategy. In the high-tech of deep-sea oil and gas exploitation, dynamic positioning technology is one of the important auxiliary technologies. [0003] In the field of dynamic positioning, rese...
