Underwater Radiated Noise


Limiting environmental impact on marine life

Thousands of commercial ships traverse the open sea each day—becoming a major source of underwater radiated noise (URN). This type of low-frequency ambient noise in oceans can have a devastating impact on marine life, particularly on fish and whale populations. Most likely, onboard sources of URN also directly are directly linked to onboard noise and vibration levels. This negatively impacts passenger and crew comfort.

Today, the European Marine Strategy Framework Directive and the International Maritime Organization (IMO) have established standards and guidelines to mitigate the shipping industry’s noise footprint. BV Solutions M&O offers design assistance and accurate measurement expertise to help asset owners and operators reduce environmental impact while responding to IMO concerns around the issue.

Unprecedented insight on noise footprint

Complying with international regulations on underwater radiated noise requires highly accurate predictive calculations on a vessel’s noise footprint. BV Solutions M&O can provide this level of precision in the form of predictive calculation, outboard measurements and onboard dedicated measurements to offer assistance to asset owners from the earliest design stage through delivery.

Leading a multi-functional team to tackle key challenges

Underwater radiated noise is a highly complex issue that requires a concerted effort involving a variety of key stakeholders to meet market expectations. BV Solutions M&O plays a key role in major research projects that bring together a multi-functional team of biologists, policymakers, engineering companies, shipyards, and shipowners, among others. By simulating ship traffic interaction with aquatic life, we can provide predictive modeling tools to policymakers that help choose which solution will work best in a given area.
