Power Quality Analysis
AC and DC systems. Modelling, monitoring and analysis — not a shelf-filling report.
If you're seeing equipment tripping without good reason, generators running rough or failing to synchronise, protection that doesn't coordinate during faults, or drives and electronics failing well short of their expected life — there's a good chance the root cause is power quality. The fast events responsible rarely show up on standard instruments.
We can help. For a fast answer we bring state-of-the-art high-frequency monitoring equipment on board for a mobile assessment. For intermittent or load-dependent problems we install fixed measurements across every operating mode. For gradual trends across a vessel or a fleet we set up long-term monitoring using the instrumentation you already have. And for vessels still on the drawing board, we model and simulate the network before it's built — so resonance, harmonic distortion and converter interactions get fixed when changes cost a drawing revision, not a retrofit.
The Problem
Why the usual tools can't see it
The symptoms are familiar: flickering lights, overheating cables, interference with navigation or communications, drives and electronics failing where manufacturers expect years of service, maintenance budgets creeping up year on year with no obvious explanation.
The events responsible — voltage spikes lasting fractions of a cycle, converter switching noise, resonance between equipment that only appears under specific loads, DC-side ripple and transients — are usually too fast, too intermittent or too load-dependent for standard power meters to catch. The data looks clean; the damage keeps accumulating.
What We Do
Power system modelling & simulation for upfront vessel design
Model the network before it's built. Identify resonance, harmonic distortion and converter interactions during the design phase — when changes cost a drawing revision, not a retrofit.
Onboard permanent & portable monitoring solutions
State-of-the-art high-frequency instrumentation. For urgent investigations, our engineers come on board with portable kit for a mobile assessment — a fast answer in days, not months. For intermittent or load-dependent issues, we leave fixed measurements in place across every operating mode for as long as the problem needs time to reveal itself. Every cycle recorded — nothing gets missed.
Ongoing data analysis for preventative maintenance
Use the equipment already installed — PMS, PLCs, generator controllers, BMS — to build a continuous picture of electrical network health. Meaningful trend analysis with engineering analysis behind the data, not dashboards nobody acts on.
Fleet management & remote analysis for energy efficiency
Vessel-by-vessel becomes fleet-by-fleet. Compare across sister ships, spot outliers, prioritise maintenance where it matters — remotely, from the data you're already collecting.
What you get
A clear diagnosis, not a report no-one will read
What's causing the problem, what damage it may already be doing, and what needs to change — filter, wiring correction, settings adjustment or design change. In many cases, the fix costs a fraction of what's already been spent on repeated repairs and lost operating time.
