科学考察船电力推进系统的低噪声设计

Low noise design of electrical propulsion system on research vessel

科学考察船电力推进系统的系统设计和设备性能与船舶的水下噪声有着密切联系,而船体的水下噪声等级将会显著影响科考作业的精度。通过对电力推进系统和重要噪声源设备进行低噪声设计,可有效降低科学考察船的水下噪声。国内已有实船验证低噪声设计的有效性,为后续科学考察船的设计提供参考价值。

The electric propulsion system configuration of research vessel is highly related to the underwater noise, which significantly affects the precision and repeatability of research equipments. It’s effective to consider low-noise requirement during electric propulsion system design and equipments manufacture for underwater noise reduction. And it’s confirmed to be practicalwith one research vessel in China, and it’s may be valuable for research vessel design in future.
