Our country's largest and most advanced navigation ship "Sea Patrol 176" has been officially commissioned.

On the 13th, the large navigational aid ship "Hai Xun 176", autonomously designed and built by our country, was officially commissioned to the South China Sea Navigation and Transportation Center. The ship is currently the largest and most advanced navigational aid vessel in our country's transportation system. The commissioning ceremony was held at the Haikou Navigation Aids Workboat Pier in Hainan. The construction of "Hai Xun 176" took three years to complete. The ship has a total length of 75.2 meters, a beam of 14 meters, a full load displacement of 2360 tons, a range of 5000 nautical miles, a maximum speed of over 15 knots, and can safely navigate in sea conditions up to level 6 and operate safely in sea conditions up to level 4. With its long endurance capability, the ship can support deployment of navigational aids in remote seas and emergency repairs. The power system of "Hai Xun 176" is a fully electric propulsion system, with the entire ship powered by a unified power station. The diesel engine units can be automatically adjusted based on different operating conditions to optimize load distribution and reduce fuel consumption in inefficient conditions. The ship incorporates various environmental protection technologies, including low-sulfur fuel tanks, sulfur oil cooling devices, and oil-water separation devices. Treated wastewater is discharged after meeting standards; the compartments are insulated with high-efficiency materials to reduce heat transfer, condensation, and improve energy efficiency. Additionally, as a domestic ship for domestic navigation, it uses seawater in the jurisdiction as ballast water, avoiding environmental pollution.
