After 10 days of sea trials, the navigation test of the “Jia Geng†scientific research ship of Xiamen University was successfully completed. The 711 has independently designed and integrated the complete low-noise main propeller shaft propeller system for the ship, including low-noise propellers, shafting, intermediate bearings, thrust bearings and high-elastic couplings. During the navigation test, the main propulsion system was subjected to a long-term full-load durability test, and the equipment provided by the 7.1 was operated smoothly, especially the low-noise propeller demonstrated superior performance in the special underwater noise and silent mode test of the ship. .
It is reported that the "Jia Geng" is a 3,000-ton marine scientific research vessel with a length of 77.7 meters, a width of 16.24 meters, a maximum speed of more than 14 knots, and an endurance of 10,000 nautical miles. It can reach all non-ice areas for marine scientific research and teaching. practice.
The ship is a comprehensive marine laboratory equipped with high-performance acoustic detection equipment and ocean observation equipment to support experimental research in hydrology, chemistry, biology, geophysics, atmosphere and related disciplines. The ship has very high requirements for vibration and noise reduction. The whole ship adopts a full-power silent propulsion scheme and applies various vibration and noise reduction measures. It is the first time that the domestically built scientific research ship is designed and built according to the Norwegian Classification Society noise class standard. Ship.
The smooth implementation of the “Jia Geng†scientific research ship project fully reflects the design and integration capabilities of the high-end scientific research ship power system in July 1st.
