Problem - background - statistics Ocean Noise pollution is an escalating environmental problem caused by human activities. This includes things like drilling into the sea bed, maritime vessel’s engine’s, propellers noises, and global shipping. A once relatively quiet environment dominated by the natural sound of marine communication, Has now turned into a nonstop industrial worksite. In the last 50 years underwater noise levels have increased dramatically. The main contributor is global commercial shipping. These include things like Cargo ships and shipping container vessels which both emit the equivalent of around 190 decibels (Db) of underwater noise, which is deafening to marine life within the proximity, and because sound travels 4 times further underwater, that proximity can be massive. In 2023 a research article showed that worldwide, the international commercial fleet numbered more than one hundred thousand ships, and was growing rapidly. This is a massive issue for the marine environment, because it interferes with the marine animals that rely on sound for navigation, feeding, and communication. Innovative solution My innovative solution is to redesign propulsion systems for large container ships to reduce underwater noise and to improve efficiency. The system would feature modified hybrid propulsion combined with new propeller designs. The hybrid propulsion would combine both diesel and electric motors for rotational thrust to the prop shaft. The propulsion would use a revolutionary new hi tech designed propeller, replacing the traditional style of propeller which was invented in the 1800’s. This is because the new high tech propeller would be designed to be more quieter and more efficient the cavitations There have been some great advancements in prop design in recent years, and now is the time to advance these designs to large vessels to make a bigger impact on solving this issue. The new propulsion system is designed to run more efficiently at a lower RPM (rotations per min) which will reduce Cavitation and vortices, improve fuel efficiency, reduce overall energy consumption during long-distance travel, and cut down noise pollution dramatically. Finally, the propeller would be manufactured using recyclable or partially recyclable marine-grade materials, such as advanced metal alloys, to reduce environmental impact at the end of the vessel’s service life. Solution how are you going to solve this A first step would be getting big shipping companies to do as little as slowing ships 10-20%, it can benefit the marine ecosystem twice as much. By reducing the amount of speed, a ship is going at. It can significantly decrease underwater noise and reduce the risk of ship strikes on marine animals. Another approach is collaboration with shipbuilders, marine engineers, conservation organizations, and the shipping industry. Marketing would emphasize the dual benefits of environmental protection and economic efficiency, including lower fuel costs, reduced maintenance, and alignment with global sustainability goals. By reducing both anthropogenic noise (human generated sound) and vessel collisions with marine life, this vision promotes a safer, quieter ocean that supports marine ecosystems while sustaining the human communities that rely on it. The ocean isn’t waiting forever; we need to act now.
