Refit and equipment change
A refit starts with the boat as it exists, not only the drawings on file. MarineFS uses available records, measurements, inspection, photographs, and owner- or partner-provided 3D scan data to establish the affected area, define the change, and prepare installation and closeout information.
Refit baseline
3D scan data can improve the geometry, but it does not replace records, inspection, or physical verification. The baseline should cover only the area and level of accuracy needed for the installation, fit, or reverse-engineering task.
Collect the available drawings, equipment data, maintenance records, photographs, and prior change information. Inspect the affected area, capture the geometry that controls the work, and mark missing or conflicting information before defining the change.
Before 3D capture, define the area, datum, required accuracy, exclusions, who controls the data, where it may be used, and the dimensions that must be checked physically. Use point cloud or surface data only after its coverage, registration, and accuracy are understood. Derive only the geometry and drawings needed for fit, routing, alignment, replacement, or repeatability.
Compare the current and proposed configurations. Identify changes to foundations, attachments, access, and service clearances. Then trace the effects on electrical load, controls, cooling, fuel, exhaust, communications, operator use, installation sequence, and testing.
Define the function, geometry, interfaces, materials, and attachments for supplier-built aluminum or composite parts. Record corrosion controls, fabrication constraints, and inspection needs. Where required, use load, laminate, structural, and review inputs accepted by the responsible qualified party.
Prepare the drawings, interface data, supplier actions, installation checks, commissioning steps, and test requirements needed by the yard and installers. Record field discrepancies and accepted changes as they occur so the as-built package reflects the work performed.
What the project receives
Existing-condition baseline and unresolved data list
Geometry limited to the stated fit or replacement task, with defined interfaces
Change-impact and installation package
Commissioning, discrepancy, and as-built records
Standards and review
Identify the owner, OEM, contract, ABYC, ISO, class, flag, and regulatory criteria that apply to the change, then relate them to the boat's construction, service, records, and known modifications. 3D scan data does not establish hidden structure, material condition, load capacity, or compliance. Regulated calculations, structural substantiation, certification, and authority acceptance remain with the qualified or authorized party responsible for them.
