The article highlights the environmental advantages of vessel electrification, particularly focusing on the efforts of Robert Allan Ltd (RAL) in designing all-electric tugs like the HaiSea Wamis to mitigate underwater radiated noise (URN). URN, a concern due to its harmful effects on marine life, is being addressed through collaborative projects with Sanmar Shipyards and ABS. Data collected during sea trials demonstrated that the electric propulsion system of the HaiSea Wamis produces less noise and vibrations compared to traditional diesel tugs. The vessel received an Underwater Noise Notation from ABS, showcasing its sustainability and operational benefits, including quieter crew spaces and efficient battery capacity design. In addition, the article emphasizes the performance advantages of battery-electric tugs, such as faster acceleration and lower CO2 emissions. The clean electricity grid in Vancouver, powered by hydropower, further enhances the environmental credentials of all-electric tugs. The article concludes by mentioning upcoming conferences focused on vessel electrification, inviting further exploration of green advancements in maritime technology.
