ONEX Peace, an Aframax tanker built by Hyundai Samho Heavy Industries and delivered to its owner ONEX, has become the world’s first merchant ship to receive DNV’s SILENT-E notation
DNV is the first classification society to offer an underwater noise notation, SILENT-E, which ensures ships do not exceed average-to-moderate underwater radiation noise levels.
Vessels with this notation can minimise their impact on marine life and document noise performance for authorities, or those requiring proof of noise emissions for transit through vulnerable areas.
ONEX DMCC Dubai UAE director of corporate communications Gemma McQueen said “ONEX Peace is a competitive ship that can operate in waters with strict regulations without disrupting the sea’s ecosystem.”
She added, “This proven low-noise technology will create the capability to deliver improved operational performance, expand operational routes, and enhance environmental management of the ship.”
Hyundai Heavy Industries (HHI) senior executive vice president Won-Ho Joo said, “In a highly competitive market, HHI has proved its capability to build a high-quality ship with improved fuel efficiency while satisfying eco-friendly underwater noise standards.”
“We will strengthen research and development on low-noise and green ships to ensure our continued competitiveness in the future era of eco-friendly ships.”
"We are very pleased to achieve the world’s first DNV SILENT-E notation certification for a merchant ship with our technical support,” said Korea Research Institute of Ships & Ocean Engineering (KRISO) president Booki Kim. “We will actively support the industry by continuously developing eco-friendly and low-noise ship-related technologies that proactively respond to IMO environmental regulations and take the lead in the development of marine environment protection technologies.”
DNV, HHI and KRISO are conducting a joint research project on measuring and evaluating underwater radiation noise. As part of the study, the parties carried out the underwater noise measurement and analysis of ONEX Peace. Subsequently, DNV granted the SILENT-E notation, verifying it meets the requirements of certification.
“By receiving the notation, ONEX and HHI demonstrate they are taking steps to minimise the impact of shipping on the environment,” said DNV regional manager for Korea and Japan, Vidar Dolonen, “This is becoming increasingly important for stakeholders at all levels of the value chain, and we hope that the awarding of this notation is another important milestone that will help to raise standards in shipping to the next level.”
