Marine research ships require very low levels of underwater radiation noise to minimize the impact on underwater life. 

It is said the the noise generated by the machinery and thrusters mounted on the ship and propagating into the water overlaps with the life frequency band of marine mammals, causing great damage to the creatures.

The MTU generator sets designed and manufactured by yusinHR for eco-friendly low-noise ships the protect the blue sea satisfies this underwater radition noise regulation, and it was the first high-speed generator set in Korea.
