System and method for marine underway detection of seabed gas eruption

Abstract

The invention discloses a system and method for the marine underway detection of seabed gas eruption, and the system comprises a tugboat which is provided with a general control machine; a measurement device which comprises a main box, a floating cable, a power supply electrode line and a measurement electrode line, wherein the power supply electrode line and the measurement electrode line are fixed on the floating cable. The main box is connected with the tugboat through a mooring rope. The power supply electrode line is provided with two power supply electrodes, and the measurement electrode line is provided with a plurality of measurement electrodes. The power supply electrodes and the measurement electrodes are respectively connected with a main unit module in the main box. The floating cable is provided with a balance weight and a floating ball. The system also comprises a positioning device which is used for the positioning of the measurement device. The system can achieve the marine underway in-situ detection of gas eruption, is simple, quick and accurate in detection process, is low in cost, and can achieve the real-time and repeated detection.

Description

technical field [0001] The invention belongs to the technical field of marine detection, in particular relates to the detection of seabed gas eruption, and more specifically relates to a system and method for navigating in waters to detect seabed gas eruption. Background technique [0002] Bubbles (groups) overflow of different scales are ubiquitous on the seafloor, and their sources are mainly some gas components produced by thermal decomposition and biodegradation, including water, hydrocarbons, hydrogen sulfide or carbon dioxide, among which hydrocarbons Mainly. At present, the biggest cause of destabilization accidents of submarine drilling platforms is the seabed instability caused by subsea gas eruption. Therefore, the study of subsea gas eruption is very important to the safety of drilling platforms. Moreover, since the gases erupted by bubble groups are mainly greenhouse gases, accurately grasping the seabed gas ejection path, scale and other factors also plays an i...
