DNV rewards the first merchant vessel with a SILENT-E rating
The classification society DNV has announced that ONEX Peace, an aframax tanker – built by Hyundai Samho Heavy Industries and delivered to its owner ONEX – became the first merchant vessel in the world to receive a SILENT-E rating from DNV.
Ship engines, underwater explosions, sonar and oil drilling fill the marine environment with noise pollution.
Research shows that low frequency sound waves can interfere with the behavior, communication and migration of aquatic mammals, including dolphins and whale species. Many human marine businesses are also negatively affected by noise pollution, including emergency response and offshore activities where sound waves interfere with communication with underwater equipment.
The SILENT-E rating ensures that vessels do not exceed medium to moderate underwater noise levels. Vessels with this rating can minimize their impact on marine life and document acoustic performance for authorities or for those who require proof of noise emissions for transit through vulnerable areas.
Gemma McQueen, Director of Corporate Communications at ONEX, said: âONEX Peace is a competitive vessel that can operate in strictly regulated waters without disrupting the marine ecosystem. This proven low noise technology will create the ability to deliver improved operational performance, expand operational routes and improve the environmental management of the vessel.
