01 / CORE MATERIAL
Balance weight and compression
Select the PUFOAM grade against the required density, compressive behaviour, closed-cell structure and water exposure. The core, surrounding shell and load paths must be assessed together.
Application / Wind energy
Floating-Wind Buoyancy Cores
PUFOAM core blocks for floating offshore wind pontoons are manufactured, bonded and machined as a coordinated assembly. Block layout, bond quality and final geometry determine how reliably the core fits the surrounding structure.
Engineering requirements
From foam blocks to a fitted core
02 / MANUFACTURING
Design the joints before machining
Divide the CAD model into blocks that can be bonded, fixtured, machined and transported. Retain common reference points between the bonding platform, CNC fixture and final assembly.
Engineering requirements
Control the interfaces
| Stage | What must be controlled |
|---|---|
| Bonding | Clean and prepare the foam faces; control adhesive coverage, joint gaps, positioning and clamping throughout cure. |
| Machining | Maintain common datums; machine mating faces, outer contours and designed bond-flow grooves without damaging the foam. |
| Inspection and delivery | Check contour and joint fit; identify each block against the assembly drawing, remove dust and protect surfaces against moisture and transport damage. |
| Assembly validation | Confirm the chosen foam and adhesive together under the project load and water-exposure conditions. |
