The slightest deviation in the machining, polishing, and finishing of ships’ propeller blades could result in underwater radiated noise and cavitation, even if defects are within the maximum tolerance allowed by classification societies and the ISO 484-1 standard....
Oscar Propulsion and the University of Strathclyde have developed technology that substantially reduces the underwater radiated noise generated by ships’ propellers. The patented PressurePores system reduces propeller tip vortex cavitation by applying a small number...
A speed limit for commercial ships in European Union waters could bring an estimated EUR 3.4-4.5 billion in socioeconomic benefits. In addition, it reduces underwater noise, the risk of ships colliding with whales and greenhouse gas emissions. This follows from a...
RH Marine has developed a new green dynamic Positioning (DP) system, which optimises the fuel consumption of generators and thrusters. As a result, ships can sail more efficiently and save fuel. By switching completely to batteries, the DP system also enables vessels...
Noise from ships disturbs and threatens marine life. In the European project SATURN, twenty project partners from ten countries will work on a cleaner, quieter maritime sector over the next four years. The focus will be on solutions for reducing and mitigating the...
