Brüel & Kjær recently delivered their HVME (Hull Vibration Monitoring Equipment) solution to BAE Systems Submarine Solutions.
The HVME system will be deployed on HMS Audacious, the fourth boat in the UK Royal Navy’s Astute-class, nuclear-powered attack submarine construction programme.
The Brüel & Kjær HVME system will provide monitoring and analysis facilities of structure-borne noise generated in the submarine. The purpose is to assist ship staff to maintain a low noise signature by monitoring and analysing both hull vibration and hydrodynamic noise.
The state-of-the-art data acquisition and vibration monitoring system is based on Brüel & Kjær’s COTS (Commercial-off-the-Shelf) sensors and PULSE data acquisition and analysis platform.
The PULSETM modular and scalable platform, with over 12,000 systems sold worldwide, includes the flagship LAN-XI acquisition unit. The ‘hand-sized’ network-based LAN-XI modules provide a distributed architecture to give installation flexibility and drastically reduce amounts of sensor cabling.
