Project Overview
EOLMED is one of France's pioneering floating offshore wind pilot farms, located off Gruissan in the Mediterranean. Grispen was engaged by Bourbon Offshore Gaia to deliver the structural engineering for the project's Junction Box and Working Platform, critical electrical and access infrastructure mounted on the floating wind platform.
The Engineering Challenge
Floating wind infrastructure combines several engineering disciplines that rarely intersect on a single structure: marine operations (DNV-ST-N001), floating steel structure design (DNV-OS-C101), thermal management for enclosed electrical equipment, and lifting engineering for installation. The Junction Box in particular required careful thermal analysis alongside its structural design, since enclosed electrical equipment operating in a marine environment generates heat loads that must be managed within the structural envelope.
Grispen's Solution
Grispen delivered a fully integrated engineering package: operational analysis of the Junction Box under in-service floating platform motions, a dedicated lifting and installation analysis, and a thermal analysis to confirm the enclosure design managed internal heat loads adequately. The Working Platform was independently assessed for its operational load cases. All deliverables were produced using ANSYS and Staad Pro, certified to a code package spanning DNV-ST-N001, DNV-OS-C101, DNV-RP-B101, NORSOK M-501, ISO 12944-5 and AISC 360-16, reflecting the multi-standard complexity typical of European floating wind developments.
Scope of Work Delivered
- Junction Box: operational analysis under platform motion
- Junction Box: lifting and installation analysis
- Junction Box: thermal analysis of enclosed equipment
- Working Platform: operational structural analysis
- Cable routing and seanex box coordination
- Rigging structure design for Junction Box installation
Our Delivery Process
Every Grispen engineering scope, regardless of size or client, passes through the same structured five-stage delivery method, ensuring consistent quality and full traceability from kick-off to final issue.
EOLMED is one of Grispen's flagship floating wind references, demonstrating direct, hands-on experience with the structural, thermal and installation engineering disciplines that the emerging Australian and APAC floating wind market will require in the years ahead.
