Renewable Offshore & Onshore Wind CAD

Automated parametric models of wind foundations and secondary steel. Give us your parameters — we give you the 3D model and the 2D drawings, in the shortest possible time.

Send us your parameters See what we model

Automated

Parametric templates generate each model from your inputs.

3D + 2D

Native and STEP models with GA and fabrication drawings.

Fast

Change a parameter, get an updated model and drawing set.

Primary steel

Foundations, modelled from your parameters

Monopiles, transition pieces and jackets are built from automated templates. Every dimension is driven by a parameter, so a design change becomes an updated model and drawing set quickly.

Yellow monopile foundation standing in the sea

Monopiles

Cans and cones, wall-thickness schedules, flanges, appurtenance interfaces and elevation levels — generated from your design basis.

Offshore wind transition piece with access platform and davit crane

Transition pieces

TP shell, grouted or bolted connection, main platform, internal platforms and all primary interfaces to the tower and secondary steel.

Four-legged jacket foundation with transition platform

Jacket foundations

Legs, braces, X-nodes and K-nodes, pile sleeves and the transition structure — parametric from leg spacing, bay heights and member sizes.

Secondary steel

Every platform, ladder and boat landing

Secondary steel is where drawing hours disappear. Our parametric library places and details it automatically — consistent and ready for fabrication.

Airtight platforms and airtight hatches
Boat landings and fenders
Access ladders and rest platforms
Railings, handrails and guardrails
External working platforms
Internal platforms and hatches
J-tubes and cable hang-offs
Davit crane bases and lifting points
Brackets, supports and walkways

Inside the transition piece

Airtight platforms and TP internals

The airtight platform seals the transition piece from the monopile below. We model it complete with every piece of internal secondary steel around it.

Airtight deck with perimeter seal and support brackets
Airtight hatch with coaming, gasket and guard railing
Internal ladders with fall-arrest rail and wall brackets
Cable penetrations, sealing flanges and cable hang-offs
Cable junction boxes on galvanised cable racks
Bolted tower flange, stiffeners and equipment supports

How it works

Give us your parameters. We give you the model.

Send your parameters

A design basis, a sketch or a simple table of dimensions and levels is enough.

We generate the model

Our automated parametric templates build the full 3D model — primary and secondary steel.

Engineering review

Every model is checked by a chartered engineer before it leaves us.

You receive 3D and 2D

Native CAD and STEP, GA and fabrication drawings, BOMs and material take-offs.

What we need from you

Typical input parameters

Diameters, wall thicknesses and can / cone lengths
Elevations: seabed, interface, platform and hub levels
Flange, grout or bolted connection details
Platform layout, hatch and ladder positions
Boat landing orientation and fender spacing
Your drawing standard, title block and file formats

Offshore and onshore

Built on offshore wind experience in Germany

Our team brings six years of offshore wind foundation design experience in Germany, working to DIN and EN standards. The same automated approach applies to onshore wind steel structures and to any repeatable structural family.

Work is led by a Chartered Professional Engineer (CPEng, Engineers Australia), supported by a specialist team recognised by the IET (UK).
