Underwater Noise And Security

Underwater Noise And Security

Introduction

Hafnia’s deployment of live underwater radiated noise (URN) monitoring marks an important advancement in sustainable shipping—but it also intersects with maritime safety. For shipowners and operators, understanding acoustic footprints may prove vital in high-risk zones.

Industry context

While the primary goal of URN tracking is environmental compliance, the ability to monitor and manage a vessel’s acoustic signature has wider ramifications. In regions impacted by piracy or asymmetric threats, excessive underwater noise could increase detectability, making vessels more vulnerable. Beyond physical piracy, noise management supports broader ISPS Code compliance, smarter route planning, and better integration of threat intelligence.

Practical measures

• Integrate acoustic monitoring systems into onboard security assessments.
• Use reduced-noise routing in known threat zones to lower detectability.
• Incorporate URN data in risk analysis during voyage planning stages.
• Train security teams to interpret noise data for situational awareness.
• Coordinate with onboard escorts for stealth-aligned operations.
