Once the vessel is delivered, the powering calculation, the expected operating pattern and the design limits stay in the drawings. The yard hears how the boat performs by anecdote; the operator judges it against the last boat.
Solutions · By question
Do the design assumptions hold up in service?
MA-Con: design intent becomes the reference a vessel is judged against once it is working, for the yard and for the operator.
Advise In development
The documentation and calculations become the engineering model before the vessel exists. Sea trials give it a baseline. After handover, every working day is judged against it: the operator sees deviation from what this vessel should do, and the yard sees how its assumptions held, with the operator’s consent and on terms agreed up front.
The layer
The model, before there is a signal.
MA-Con carries the same engineering foundation into early design, so there is continuity between the assumptions the vessel was built to and the evidence it produces in service.
The evidence
Design intent, then measurement.
Findings at this stage rest on the design documentation and on trials, and their evidence class says so. As operating history accumulates, the model is tuned against it, and the evidence class travels with each finding.
The ladder
Advise. In development.
Feeding operating evidence back into the next design is the Advise rung, and it is in development. What exists today is the model as the reference for Monitor, and Project MARAM as the way designers and yards take part.
What that could look like
An illustration in a fictional setting · not a case study · nothing below is a measured outcome
A yard delivers a new pilot boat to Nordkap Pilotage. The powering calculation says the boat should hold its service speed at a stated engine load. Through the first season MA shows the days when it needed more, and where: mostly on the outbound leg into the ebb. The operator asks whether the hull needs cleaning. The yard asks whether the assumption needs revisiting for the next boat. Both are looking at the same evidence.
