You already know the loads.

For naval architects and structural engineers: what happens between your drawing and the finished component, and the records that prove it.

01Engineering intent

Analysis stops at the drawing.
Fabrication starts at the mould.

Between the two, decisions about laminate schedule, fibre orientation, consolidation and tooling decide whether the component behaves the way your model said. We treat them as engineering decisions, and we show our work.

02The component

Your model,
built faithfully.

Reviewing digital component geometry

We work directly from your geometry and your design environment.

Engineering load calculations

Load cases, load paths and structural requirements, analysed rather than assumed.

Composite component tooling in the workshop

Laminate schedule, fibre orientation and consolidation strategy, determined by the load path.

Composite part sealed under a green vacuum bag, technicians working around it in the factory.
Bagged and under vacuum. Consolidation is where the laminate schedule becomes a structure.

Prepreg carbon under controlled cure, by craftspeople who have spent decades doing it.

Ultrasonic inspection of a finished laminate. What the analysis predicted, the probe confirms.

NDT ultrasound inspection, structural calculations, Safe Working Load documentation and manufacturing records.

03The analysis

Ask your questions

If you want to see how a decision was reached, ask. We will show you the analysis. That is what it means to be an engineering house rather than a fabrication shop.

04The records

What comes back
with the component.

The analysis and the manufacturing records travel with the part, so what you signed off is what you can check, and what the yard holds is what you hold.

01

Analysis report.

Load cases, load paths and the margins at the attachments.

02

Laminate schedule.

Fibre orientation and ply schedule as built, not as proposed.

03

Cure log and manufacturing records.

Traceability from first ply to final inspection.

04

NDT results and Safe Working Load documentation.

Internal condition and rated loads for the tack, bobstay, stay and sheet attachments the component carries.

From Cape Town
to any ocean.

Everything we build leaves one factory.
We do not choose which ocean it meets, so we build for all of them.
