World’s Quietest Ships Powered by MaK Engines

When the new ocean research vessel DONGFANGHONG 3 begins its deep-sea observations in 2017, it will do so very, very quietly—thanks to a solution developed by Caterpillar’s Application Engineering team based in Kiel, Germany, and Cat® dealer MaK Asia.

Currently under construction at Jiangnan Shipyard in Shanghai, China, DONGFANGHONG 3 will be used by the Ocean University of China for a variety of oceanographic research—everything from exploring subsea volcanoes, to investigating hydrographic and geological formations, to operating ROVs (remotely operated vehicles).

These efforts require as little noise, vibration and water disturbance as possible to ensure accurate scientific measurements. For that reason, the new vessel must comply with the world’s strictest underwater noise limitations, known as DNV GL Silent-R.

Ocean University of China considered several brands of engines to power DONGFANGHONG 3, ultimately selecting two MaKTM 9 M 25 C and one MaK 6 M 20 C generator sets with a unique double-resilient mounting solution design.
