Abstract

The invention belongs to the technical field of marine ships, and discloses miniature salvage drilling device and method coordinated with ROV for a marine oil tanker. The device comprises a main frame, a pre-positioning device, an accurate positioning device, a hollow drilling rig, an oil pumping valve, a hydraulic control valve unit, an electronic control cabin and an assorted sensor, wherein the oil pumping valve is connected with the main frame through a clamping mechanism of the oil pumping valve; the pre-positioning device is arranged on the periphery of a front base plate of the main frame; the accurate positioning device is arranged on the front base plate of the main frame; the hollow drilling rig is arranged in the center of the main frame; the hydraulic control valve unit, the electronic control cabin and the assorted sensor are arranged at the rear part of the main frame. The miniature salvage drilling device disclosed by the invention is small in volume and light in weight, can be conveniently loaded by the ROV to carry out operations under seawater without the complicated hoisting operation, and can further be attached to a ship wreck in any random posture, so that the device is very suitable for the situation that the posture of the ship wreck is undefined in the seabed.

Description

technical field [0001] The present invention relates to a device and method in the technical field of marine ships, in particular to a drilling device and method for salvaging sunken ships on the seabed in cooperation with ROV (Remote Operated Vehicle, underwater robot). Background technique [0002] In recent years, with the development of the petroleum industry and maritime transportation, especially the rapid increase in the number of oil tankers, marine pollution caused by shipwrecks or leaks has occurred from time to time. Oil is a highly polluting chemical. If oil leaks in the ocean, it will pollute the surrounding environment and even affect the surrounding ecological environment. [0003] The prior art generally adopts the method of drilling-extracting oil to salvage. First, a hole is drilled on the oil tank of the tanker, and an oil pipe is connected to the hole, and the oil is pumped to another tanker through the tube; after the oil on the tanker is drained, Re-se...
