DNV: Minimizing underwater noise from merchant vessels
Underwater noise is known to harm marine wildlife and is an increasing concern throughout the industry. Now DNV’s SILENT-E class notation has been awarded to a merchant ship for the first time.

ONEX Peace, an Aframax tanker built by Hyundai Samho Heavy Industries (HSHI), is the first merchant vessel which meets the Canadian requirements.
