01
Measure what the crew feels
Purpose-designed sensors capture continuous vibration, discrete impacts, vessel motion and seat response at the point that matters.

VIMMS measures whole-body vibration, impacts and vessel motion in real time — giving operators useful feedback at the helm and managers clear evidence ashore.

VIMMS has grown through practical measurement work—installing equipment, recording vessel and seat response, and turning the results into information that operators can use.
The VIMMS platform
From the seat to the shore.
The conditions at sea change by the minute. VIMMS keeps the measurement chain connected: crew, vessel, journey and fleet.
The result is more than a peak number. It is a time-based record of what happened, where it happened and what the people on board were exposed to.
02
Make it useful at the helm
A calm live display gives the operator immediate feedback without taking control away from the person driving the vessel.
03
Turn every passage into evidence
Fleet and journey views bring together exposure, impacts, speed, position and operational context for review and action.
A critical distinction
Impact is a moment.
WBV is the working day.
A vessel can record few severe impacts and still expose its crew to high levels of continuous vibration. One measurement cannot be used as a substitute for the other.
What happened in an instant?
Peak acceleration, impact count and severity identify individual shock events and how often they occur.
What accumulated over time?
Frequency-weighted RMS, VDV and daily exposure A(8) describe continuous vibration across the working period.
VIMMS measures both — because a complete exposure picture needs both.
One connected view

For the operator
Clear live information designed to be understood at a glance in a demanding working environment.
For the manager
Journey, crew and fleet evidence that helps identify patterns, compare operation and document action.
For the engineer
Time-synchronised motion, impact and seat data for understanding the vessel–seat–occupant system.
Workboat Code 3 & WBV
Move from assumption
to measured evidence.
Managing vibration risk starts with measuring crew exposure using the right metrics. VIMMS supports ISO 2631-1 whole-body vibration assessment while retaining the separate impact record needed to understand high-speed craft operation.
- Daily exposure expressed as A(8)
- RMS and VDV retained with journey context
- Evidence to support risk assessment and review
- Clear separation of WBV and impact monitoring
VIMMS supports — but does not replace — a competent risk assessment and the operator's wider health and safety process.

Maritime Systems
Engineering first.
Evidence always.
Maritime Systems is a British marine technology company founded in 2012. Our work brings together mechanical engineering, vessel dynamics, sensing and software to make difficult operating questions measurable.
VIMMS has been shaped through demanding defence, government, commercial and research applications — with a single purpose: better decisions for the people who operate fast boats.
