The classification society, DNV, says its expects growing interest from Middle East shipowners in its new SILENT-E notation which ensures ships do not exceed average-to-moderate Underwater Radiation Noise (URN) 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 Peace, an Aframax tanker built by Hyundai Samho Heavy Industries (HSHI) and delivered to its owner ONEX, an international energy trading company registered in the UAE, has recently become the first cargo ship to receive the SILENT-E notation. “ONEX Peace is a ship that can operate in waters with strict regulations without disrupting the sea’s ecosystem,” says Gemma McQueen, Director of Corporate Communications at ONEX DMCC Dubai. “This proven low noise technology will create the capability to deliver improved operational performance, expand operational routes, and enhance environmental management of the ship.”
DNV, together with shipbuilder HSHI and Korea Research Institute of Ships & Ocean Engineering (KRISO), is conducting a 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 the ONEX Peace. Subsequently, DNV granted the SILENT-E notation, verifying that the vessel meets the requirements of certification.
