Our modern equipment and experienced specialists enable us to perform complex underwater technical work, both as a part of engineering surveys at the design stage of offshore oil and gas production facilities, and on already existing subsea production facilities, pipelines, and abandoned wells. For these tasks, we utilize our own Sperre SUB-fighter 15k remotely operated underwater vehicle (ROV), or those of our partners. For many years, MAGE JSC has successfully surveyed and monitored the technical condition of Russia's only subsea production facility in the Sea of Okhotsk, ensuring the stable operation of the gas condensate field. The annual ROV underwater technical work package includes:
• visual inspection of underwater facilities for leaks, damage, foreign objects, soil erosion, and sediment;
• removal of biological fouling from main control mechanisms, indicators, connectors, information signs, and lifting devices;
• monitoring the state of electrochemical protection;
• determining the planned elevation of objects and their inclination angles;
• tracing linear objects, including route burial and their deviation from the design position;
• environmental monitoring of the environment (sampling of water, soil, gas, and biota).
Thus, JSC MAGE's experience using ROVs at the subsea oil and gas complex serves as an example of the successful implementation of modern technologies to ensure the reliability and safety of the operation of subsea oil and gas infrastructure in the Arctic and the Sea of Okhotsk.
