News from this site on July 27. According to CCTV News yesterday (July 26), the "Haiyang Dizhi No. 26" survey ship completed its first "ship installation" combined sea trial in the Qiongzhou Strait after commissioning. . Introduction to the "Haiyang Dizhi No. 26" research vessel The "Haiyang Dizhi No. 26" research vessel project was launched in October 2020, and the design plan was approved in November 2021. Construction will begin in July 2022, and it will be launched in December 2023. , which will complete comprehensive sea trials and other work in April 2024, is a new multi-functional scientific survey ship positioned for comprehensive geological survey and research of islands (reefs), and is affiliated to the China Geological Survey of the Ministry of Natural Resources.

The ship has a gross tonnage of 1311, a total main engine power of 2426 kilowatts, a ship displacement of 1713 tons, a total hull length of 63.5 meters, a molded width of 12.6 meters, a molded depth of 4.6 meters, a draft of 3.2 meters, a crew of 34 people, a self-sustainability of 35 days, and an endurance of 3500 nautical miles. The entire ship is propelled by dual-machine full-rotation rudder propellers, equipped with a bow thruster and a DP1 dynamic positioning system, and has good stability, maneuverability and seaworthiness.
It is reported that the ship is equipped with 32 sets of advanced marine geological survey technology equipment such as marine engineering drilling systems, static cone sounding systems, multiple sets of geophysical survey systems and marine operation support systems, and can be used for marine engineering exploration, marine energy and mineral surveys, Comprehensive survey of island (reef) natural resources and other multi-category surveys.
This sea trial mission
This sea trial mission includes a number of key tests such as multi-beam, ocean magnetism, single-channel seismic, and ship power systems. It aims to obtain important test data for the next stage of ocean and island reef survey operations. Provide strong technical support.
Based on the report, this site briefly attaches the relevant test items as follows:
Multi-beam detection refers to obtaining underwater high-density banner-type seafloor terrain data through wide-angle transmission and multi-channel directional reception technology, which can greatly improve seafloor topography survey accuracy, resolution and work efficiency.
Ocean magnetometry is a method that uses the magnetic differences in seafloor rock formations to detect the Earth's magnetic field. It plays a key role in studying marine geological structures, predicting mineral resources, and studying seafloor spreading and plate tectonics.
Single-channel seismic survey is a technology that detects the structure of seafloor strata through the propagation and reflection of seismic waves. It can penetrate and resolve sedimentary strata 100-200 meters deep. It is widely used in marine engineering geological exploration and geological disaster prediction. It provides Provide important data support for the formation process of stratigraphy and identification of seafloor geological bodies.
