China Shipbuilding's large-scale hydrographic survey ship in deep sea opens "new chapter" in maritime surveying and mapping

"Haixun 08" is designed according to the unlimited sailing area, with a length of 123.6 meters, a width of 21.2 meters, a depth of 9.3 meters, and a draft of 5.8 meters. meters, with a maximum speed of 16 knots. It can safely navigate in sea conditions of Level 9, carry out drifting measurements in sea conditions of Level 5, and carry out survey operations in sea conditions of Level 4. It is the first full-rotation propulsion survey and survey ship in the world that meets this silent level. ship.

The ship has low overall energy consumption. It adopts a comprehensive power system, is equipped with an energy efficiency management system and intelligent energy-saving equipment. The diesel engine, boiler, incinerator and other emissions it is equipped with meet the highest emission indicator requirements of IMO. Equipped with multi-beam sounding equipment, 10,000-meter shallow stratum profiler, acoustic noise monitoring system, ADCP acoustic Doppler flow profiler, and a completely self-designed full-sea depth acoustic measurement and positioning system that combines high precision and efficiency. . For the first time, a whole-ship acoustic monitoring system has been installed on a domestic ship, which can scientifically guide the corresponding measurement work in an environment that meets the ship's vibration and noise indicators to ensure that the detection, monitoring, observation and analysis test experimental data obtained by the ship are true and reliable. For the first time, the "three-dimensional measurement command system" is adopted to highly integrate the whole ship navigation system, ship machine system, information system and measurement system, greatly improving the informatization and intelligence of measurement.

After the ship is put into use, it can support the maritime department to achieve high-precision and high-resolution acquisition, processing and mining of marine spatial geographical information data from shallow water to deep water, from the water surface to the shallow stratum. , promote the full coverage of marine geographical information collection mainly focusing on navigation information, and expand the development of maritime surveying and mapping from coastal to offshore and offshore, which will effectively improve the comprehensive navigation support capabilities of my country's maritime sector in dealing with far-reaching sea waters.
