Reduction of Underwater Radiated Noise in Focus at IMO Meeting
Underwater radiated noise is on the agenda at the ongoing IMO meeting in London. Danish Shipping is participating and hopes that more countries will support the use of IMO's guidelines and contribute to reducing harmful underwater radiated noise to benefit vulnerable marine environments.
This week, the United Nations' International Maritime Organization (IMO) is holding a meeting in London. Underwater noise is one of the topics being discussed at the meeting of the Sub-Committee on Ship Design and Construction (SDC). Danish Shipping is attending the meeting and is closely following the discussions.
"Underwater radiated noise can harm marine animals and disrupt their communication and navigation. Therefore, we have a responsibility to ensure that our ships minimise the impact of underwater radiated noise wherever possible. It sends an important signal that Danish Shipping has adopted a policy recommending our members follow IMO's guidelines in this area. I hope this can serve as inspiration for shipping associations and companies in other countries, so we can collectively work to reduce underwater radiated noise," sid Nina Porst, Director of Climate, Environment, and Safety at Danish Shipping.
Underwater radiated noise can harm marine animals and disrupt their communication and navigation. Therefore, we have a responsibility to ensure that our ships minimise the impact of underwater radiated noise wherever possible.
Last year, Danish Shipping adopted a policy on underwater radiated noise, recommending its members follow IMO's guidelines to reduce underwater radiated noise and preserve marine biodiversity. Implementing IMO's guidelines enables shipping companies, designers, and operators to reduce noise without compromising vessel efficiency or safety.
IMO adopted its guidelines in 2023 and is currently in an "experience-building phase" running until 2026. During this period, member states are encouraged to apply the underwater noise guidance and gather feedback on its implementation. The goal is to assess its effectiveness, identify potential improvements, and enhance the guidelines' practicality.
At the IMO meeting, discussions are expected on whether this experience-building phase should be extended.
"Fundamentally, I believe the agreed experience-building period running until 2026 is reasonable. Whether it is sufficient time is hard to predict at this stage, but the most important thing is that we take constructive steps forward together to reduce the harmful impact of underwater radiated noise on marine environments," says Nina Porst.
