Dalian Maritime Bureau uses drones for the first time to monitor marine pollution


In order to fight against the comprehensive management of the Bohai Sea and increase its deterrent to illegal sewage discharge at sea, the Dalian Maritime Safety Administration recently launched the first drone maritime cruise supervision activity, using a combination of drone cruise, remote monitoring and on-site inspection. Comprehensively grasp the dynamics of maritime pollution sources to prevent air pollution and water pollution caused by illegal discharge of ships at sea.

In recent years, China‘s maritime supervision has become increasingly complicated. The maritime task of combating illegal sewage is getting heavier and heavier. Relying on existing equipment such as sea cruisers has not been able to meet the needs of today’s three-dimensional integration of “sea, land and air”. New equipment and means are urgently needed to strengthen supervision and effective control of the waters under its jurisdiction. As a modern remote-control aircraft, drones have gradually matured in technology and have been widely used in military and civilian fields. Due to the characteristics of flexible maneuvering, high timeliness, low cost, low loss, low risk, strong monitoring ability, and wide coverage, it is very suitable for the supervision of water affairs. The maritime system is equipped with drones, which is effectively combined with patrol ships, VTS, AIS, LRIT and other supervision systems, which can promote the construction of a safety supervision system featuring "omnidirectional coverage, all-weather operation, and full-process monitoring", and comprehensively improve maritime administration And ability to serve the public.

Recently, law enforcement officers of the Dalian Maritime Safety Administration carried out drones on maritime patrol vessels to cruise the densely-traveled waters such as the Old Tieshan Waterway and the Dasanshan Channel. This operation was shared for 6 hours, with a cumulative cruising range of 51 nautical miles, covering an area of 133 square kilometers. Use the ship-borne drone to cruise the above waters in all directions, accurately and intuitively receive the data by means of drone warning, single ship tracking, real-time monitoring and other means to monitor the sea surface conditions in the channel and the ship's sewage, thereby Form a new "trinity" cruise law enforcement model of sea, land, and air, resolutely rectify illegal sewage discharge in the sea area, protect the marine ecosystem, and escort for the comprehensive management of the Bohai Sea.

In the next step, the Dalian Maritime Administration will take this cruise as an opportunity to further explore the application of drone technology in monitoring environmental pollution in the waters, maritime search and rescue emergency, and three-dimensional maritime cruise. Through the drone inspection, the overall cruise cost will be reduced. Improve the efficiency of marine pollution disposal and enhance maritime cruise monitoring and comprehensive law enforcement capabilities.
