Reducing Underwater Ship Noise to Meet EU Environmental Regulations and Protect Marine Life

transportPilotedTRL 7

Ships make a lot of noise underwater, which is like living in a room with a loud vacuum cleaner running 24/7 for fish and whales. This project finds the best ways to quiet down ships without making them more expensive to run or increasing their pollution. It moves from small lab tests to real-world, full-scale ship trials to prove these solutions actually work.

The business problem

What needed solving

Ships create underwater noise that harms marine life, and new EU directives are setting strict thresholds for these effects. Companies need a way to quiet their ships without increasing fuel costs or greenhouse gas emissions.

The solution

What was built

The project is delivering full-scale demonstrators of noise reduction technologies and tools to predict underwater radiated noise.
