Hafnia Launches Groundbreaking Underwater Noise Monitoring
Hafnia has partnered with DNV to introduce a pioneering pilot project aimed at measuring and managing underwater radiated noise (URN) from tankers. This initiative marks the first permanent onboard system that connects a vessel’s underwater noise profile with real-time measurements. The project, recently implemented on the 2015-built LR1 Hafnia Excel, aims to tackle one of the shipping industry’s less visible environmental challenges.
Innovative Technology for Marine Noise Management
The newly installed systems on the Hafnia Excel will continuously monitor underwater sound levels, capturing fluctuations during regular ship operations. This data will be compared with external hydrophone readings, creating a comprehensive understanding of how vessels contribute to marine noise pollution. Following this initial setup, the 2015-built MR2 Hafnia Osprey is scheduled to receive the same technology during its upcoming drydocking.
Hafnia, a Singapore-based product tanker giant, aims to develop a comprehensive “noise management plan” applicable across various vessel types. The insights gained from this project are expected to aid compliance with tightening International Maritime Organization (IMO) guidelines and influence future ship designs and operational strategies. Ralph Juhl, Hafnia’s executive vice president and technical director, emphasized the importance of addressing underwater noise, stating, “By acting early, we’re building knowledge that will guide vessel design and operations in a more sustainable manner.”
Pioneering Efforts in Environmental Compliance
As global regulators move toward establishing binding URN limits, the collaboration between Hafnia and DNV positions the BW Group-backed owner as a frontrunner in addressing this emerging environmental issue. Øystein Solheim Pettersen, head of section for noise and vibration at DNV, highlighted the significance of this pilot project, noting that it represents a substantial advancement in quantifying and verifying underwater noise emissions across the global fleet. He remarked that the system provides a novel approach to tracking and verifying the effectiveness of noise-reducing measures.
While current URN standards remain recommendations, Hafnia’s proactive stance indicates a commitment to leadership in this area. The company recognizes that these standards will eventually become mandatory, and by taking early action, Hafnia is not only enhancing its knowledge but also setting a precedent for the industry.
