According to an article published in Aju Business Daily, a 115,000-ton crude carrier built by South Korea’s Hyundai shipbuilding group with underwater radiated noise reduction technology has received regulation certification from DNV, an accredited registrar and classification society based in Norway.

Group’s Sayings

The group said that its subsidiary, Hyundai Samho Heavy Industries, has delivered the crude carrier to an unidentified client. Regulation certification related to underwater radiated noise has been issued for passenger ships and special purpose vessels. This is the first time a cargo ship has obtained DNV certification.

Marine world Protection

For marine environmental protection, the group has worked with the state-run Korea Research Institute of Ships and Ocean Engineering (KRISO) and the Ministry of Trade, Industry and Energy to develop technologies for monitoring and reducing underwater radiated noise from commercial shipping

Underwater noise reduction

Marine mammals and fish use hearing as their primary sense and are highly dependent upon the sound for navigation, communication, finding food, reproduction and hazard detection. Concerns about the potential impact of human-induced noise on marine fauna prompted the International Maritime Organisation (IMO) to release a guideline for the reduction of underwater radiated noise. Various methods have been studied to reduce noise generated by propeller cavitation.
