Bureau Veritas Issues Underwater Radiated Noise Notation

first_imgzoom International classification society Bureau Veritas has developed a voluntary notation intended to assist shipbuilders and operators reduce underwater noise radiating from ships.The comprehensive set of standards and measuring services is grouped as NR614 Underwater Radiated Noise (URN). It aims to control and limit the environmental impact on marine fauna of all self-propelled ships and provide a standard and a system to assess compliance with specific vessel requirements for underwater radiated noise.It covers both shallow and deep water conditions, sets out a dedicated comprehensive measurement procedure, explains how to manage measurement uncertainties and sets specific underwater noise level requirementsJean-Francois Segretain, technical director, Bureau Veritas Marine & Offshore Division, says, “Underwater noise radiating from ships is acoustic pollution, and there is no doubt that it will be the next big area to be tackled by regulators.This notation, backed by careful research with an extensive network of partners, means we can help designers, yards and operators to be ahead of regulation. And it makes commercial sense. Reducing underwater noise directly contributes to reduced noise and vibration levels on board, which improves passenger and crew comfort. There is also a strong link between fuel efficiency and noise. Quieter ships burn less, and we can help make ships quieter and so more efficient.”One of the main drivers of the notation is to aid European stakeholders in fulfilling the requirements of the Marine Strategy Framework Directive. This aims to improve the environmental state of European waters by proposing mitigation solutions to be put in place by 2016, with their efficiency proved by 2020.The BV notation has been issued in parallel with the European research project AQUO, which is focused on underwater noise, and includes the work of 13 partners – shipyards, hydrodynamics research institutes and bio-acoustic experts – from eight countries, and an end user committee has been built to review the project, including BV’s notation.Several new expedition cruise projects have underwater noise reduction in their specifications and other passenger ship operators are discussing BV’s URN notation and its services and technical assistance for implementing noise reduction solutions. Bureau Veritas has signed a collaboration agreement with TSI S.L. a Spanish company that specialises in Dynamic and Acoustical design of quiet ships as well as noise and vibration measurements.Press Releaselast_img read more

Security Council members welcome meeting on interCongolese dialogue

In a letter to the Dialogue’s Facilitator, Ketumile Masire, Council members also stressed the need to ensure adequate representation of Congolese women in the preparatory process and voiced their backing for Mr. Masire’s efforts to achieve that goal. “[The members of the Council] support your appeal and urge the Congolese parties, signatories of the Lusaka Agreement, to increase representation of women at the meeting, as well as in the Dialogue,” said the 17 August letter, which was signed by the Council President for the month of August, Ambassador Alfonso Valdivieso of Colombia. The Council members stressed the importance of the role and contribution of women in the Inter-Congolese Dialogue and of ensuring that gender issues are addressed during the Dialogue, consistent with a Council resolution 1325 (2000) that urges Member States to increase the representation of women at all levels of decision-making when negotiating and implementing peace agreements. In another development, the new head of the UN Mission in the Democratic Republic of the Congo (MONUC), Amos Namanga Ngongi of Cameroon, began today a series of meetings at UN Headquarters in New York to familiarize himself with his duties, a UN spokesman told the press on Monday. Mr. Ngongi was scheduled to meet today with the UN Deputy Secretary-General, Louise Fréchette, and with the Group of Friends of the DRC tomorrow. He is expected to arrive in Kinshasa in early September. read more
