Nobody ashore sees engine load, temperature or throttle habit. Thermal creep and wave slamming go unnoticed until the emergency overhaul, and the maintenance calendar runs on run-hours and the manufacturer’s interval.
Solutions · By question
What is about to break?
Deviation from the vessel’s own engineering model, shown early, with the evidence behind it.
Predict In trial
Each vessel is judged against an engineering model of that vessel, tuned by its own operating history. When machinery behaviour departs from what the model expects at that load and in those conditions, MA raises the deviation, shows the evidence, and leaves the judgement to the engineer.
The layer
Intelligence.
Temperatures, pressures, power and motion come aboard through the gateway; the model lives ashore. Every signal is judged against what this vessel, specifically, should be doing at that load, in those conditions, on that day.
The evidence
Deviation, with its assumptions.
A machinery finding rests on the model and on history, so its evidence class says so. An engineer can open the finding, see the assumption it rests on, and question it later as well as when it appears.
The ladder
Predict. In trial.
Early deviation detection is in trial today on working vessels. What it finds is published when the evidence supports it, and not before.
What that could look like
An illustration in a fictional setting · not a case study · nothing below is a measured outcome
PILOT 4 has two engines that have run the same hours in the same water. Over several weeks the port engine’s exhaust temperature at cruising load edges away from its own history and from its twin. No alarm threshold has been crossed. MA raises the drift as a deviation, shows the weeks of readings behind it, and the engineer decides whether to look at it now or at the next alongside.
