3 Benefits of VIMMS Technology 3.1 Real-Time Accelerations
The VIMMS onboard display provides a traffic-light warning system for vessel operators.
• Alerts indicate when impact thresholds are being approached or exceeded.
• Enables immediate corrective action to reduce acute injury risk.
• Provides evidence for training and operational procedures, reinforcing safe driving behaviours.
• Each impact event is recorded and timestamped, allowing post-trial review.
3.2 Whole-Body Vibration (WBV) Monitoring
In addition to acute impact logging, VIMMS continuously captures 3-axis acceleration data from the crew seats during the voyage, filtered to the requirements of the WBV regulations.
• Individual WBV monitoring of all personnel • The WBV dashboard summarises individual exposure levels over time to assess compliance with ISO 2631-5 and HSE guidelines.
• Enables identification of vessels, routes, and operators associated with elevated long-term risk.
• Supports data-driven maintenance and vessel design improvements by highlighting vibration sources.

4 Regulatory Context
4.1 Merchant Shipping and Fishing Vessels (Control of Vibration at Work) Regulations 2007
The Merchant Shipping and Fishing Vessels (Control of Vibration at Work) Regulations 2007 set the legal framework for managing vibration exposure on marine vessels.
These regulations set the legal framework for managing vibration exposure on marine vessels, establishing mandatory limits designed to protect crew from health risks caused by whole-body vibration and repeated shocks.
Key thresholds are defined as:
• Exposure Action Value (EAV): 0.5 m/s² A(8) – the level at which employers must assess exposure and implement measures to reduce it.
• Exposure Limit Value (ELV): 1.15 m/s² A(8) – the maximum daily exposure that must not be exceeded.
Employers are required to:
• Assess and record crew exposure, particularly where the EAV is likely to be exceeded.
• Implement technical and organisational controls to reduce vibration at source (e.g. through seat design, speed management, or operational procedures).
• Provide training and information to affected personnel on the risks and protective measures.
