A circular standing platform that clamps around a 26-inch steel tower out at sea, giving crews a safe, drained place to stand. The platform is about 90 inches (2.3 m) across, built from laser-cut steel plate in two halves that are carried out and locked together around the tower, and sealed to it.
Designed from photos of an existing unit
The client had a worn platform in service but no drawings. We rebuilt the design from site photos and a handful of key dimensions, then refined it as more measurements came in from the field. Changes requested along the way, such as reducing the support dividers from nine to six per side, were built into the model.
What we designed
- Floor base in two halves: 10 mm plate with a centre opening for the tower and a side cut-out for access, with a slight fall toward the drains.
- Tongue-and-groove joints with over-centre latches: so the two halves line up and lock together on site, with room left for welding.
- Split inner shell: a two-part ring that sits around the tower and carries the floor.
- Seal ring: closes the gap between the platform and the 26-inch tower.
- Drain boxes: four recessed drain inserts that let water run off the deck.
- Support dividers and boundary wall: six radial fins per side under the floor and a perimeter wall made in four pieces.
Assembly and exploded views
Part drawings for fabrication
Every part was released with its own drawing and a flat pattern, grouped by plate thickness (8.5, 10 and 13 mm) so the fabricator could nest and laser-cut each sheet directly from the DXF files.
Deliverables
- 3D model of every part and the full assembly (SolidWorks and STEP)
- 2D drawings of all parts and the assembly
- DXF cut files grouped by plate thickness for laser cutting
- Assembly animation
- Revisions during manufacturing as field dimensions were confirmed
