Abstract

The invention provides a method for laying and recycling a seabed node, electronic equipment and the seabed node, the seabed node presets a laying target position, a recycling target position and recycling time, and the method comprises the following steps: obtaining a first current position of the seabed node by the seabed node; calculating a first position deviation between the first current position and the placement target position in the two-dimensional horizontal direction; using a motion control device for moving to the position above the laying target position in the two-dimensional horizontal direction so as to correct the first position deviation; moving to the laying target position by utilizing a first moving device; starting a return device; moving to a horizontal plane by using a second moving device; acquiring a second current position of itself; calculating a second position deviation between the second current position and the recovery target position in the two-dimensional horizontal direction; using the motion control device to move to the recovery target position in the two-dimensional horizontal direction to correct the second position deviation; and sending the recovery target position.

Description

technical field [0001] The present application relates to the technical field of oil and gas exploration and development, in particular, to a method for deploying and recovering a seabed node, electronic equipment and a seabed node. Background technique [0002] With the gradual advancement of offshore oil exploration and exploitation to the deep sea, the application requirements for obtaining information by deploying ocean bottom nodes (OBN, Ocean BottomNode) are gradually increasing. [0003] At present, underwater robots (ROV, Remotely Operated Vehicle) are used to deploy submarine nodes in deep water areas to carry a batch of nodes from the deck into the sea. The locations of are laid out point by point. After deploying the carried nodes, the underwater robot returns to the water surface and is recovered to the deck of the workboat to start the next batch of operations. The recycling process is the reverse of this. [0004] The conventional way for underwater robots t...
