MONITORING SYSTEM OF UNDERWATER MINING COMPLEX Russian patent published in 2018 - IPC F17D5/02 F17D5/06 G01M3/38 G01D5/353 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil and gas industry. System for monitoring the state of the underwater mining complex (UMC) contains a pipeline to which vibration sensors are installed with a predetermined step, sensors for determining the vertical to the ground and temperature sensors located on the electronic sensor board, as well as onshore equipment and a submarine cable. Into device additionally introduced: a stand-alone uninhabited vehicle (SUV), a bottom berthing device (BBD), an additional cathodic potential sensor was added to the electronic sensor board, ultrasonic thickness gauge, leakage sensors of the product and chemical reagent, the electronic sensor board in conjunction with a device for processing and storing information from sensors, an integrated autonomous power source and the primary device for receiving and transmitting information through the radio channel from the sensors to the SUV are combined into modules of autonomous sensors (MAS) located on the pipeline and at other sites of the underwater mining complex. At the SUV there is a secondary device for receiving and transmitting information via the radio channel from the MAS, a set of on-board instruments as part of an acoustic profilograph, an electromagnetic searcher, digital photosystem of high resolution, video system, multi-beam echosounder, side scan sonar, as well as the receiving part of the non-contact battery charging system SUV, and its transmitting part is installed on the BBD, which is connected by an underwater cable with shore equipment.

EFFECT: such implementation of the monitoring system enhances its functionality, allows timely warning of the occurrence of prerequisites for product leakage, to take necessary repair measures at UMC facilities and prevent environmental pollution of the environment.
