A hard winter of boarding runs leaves its mark on the hull and on the crew, and no record of what the boat actually met: how often it slammed, how hard, at what speed, in which direction. The survey finds the consequence long after the cause.
Solutions · By question
What is the sea doing to the boat?
Motion, slamming and the conditions met, and what they mean for hull, machinery and crew.
Monitor Live
Motion data comes aboard with the engine data, so every run carries a record of the motion the vessel met and the speed and heading it met it at. Ashore, the picture shows where and when the hard days happened, and MA judges what they mean against the limits the vessel was built for.
The layer
Sensor and edge.
Motion is measured at the gateway and travels with engine and navigation data over the same link, so the motion record and the engine record describe the same minute of the same run.
The evidence
Measurement first; interpretation labelled.
Slamming counts and accelerations are measured. What they mean for fatigue, for machinery mounts or for crew exposure is interpretation against the engineering model, and carries the evidence class that says so.
The ladder
Monitor. Live; judgement in trial.
The motion record is part of the live picture today. Judging what a season of motion means for a specific hull is Predict work, in trial alongside machinery health.
What that could look like
An illustration in a fictional setting · not a case study · nothing below is a measured outcome
A winter south-westerly runs down the Solent for three days. Nordkap’s ops room watches PILOT 7’s outbound runs to Bravo carry far more slamming than the inbound legs, at speeds the coxswains held to keep station on time. The record does not tell them what to do. It tells them, for the first time, what the boat and the crew actually met.
