Independent Review of Secondary Steel and Interface Design in Offshore Structures

Sector: Offshore Wind
Project Stage: Concept → Pre-FEED
Client Type: Offshore Project Developer (Confidential)

Client Challenge

Secondary steel and connection details were being treated as “low risk,” despite:

• Complex load transfer paths

• Fatigue sensitivity

• Interface ambiguity between multiple design parties

The client wanted assurance that secondary steel would not become a FEED or construction risk.

Equitus Role

Equitus conducted:

• Independent Review of Secondary Steel and Interface Design

• Detailed review of secondary steel assumptions

• Local FEA of brackets, nodes, and transition details

• Fatigue screening of interface components

• Recommendations for design simplification and standardisation

Key Outcomes

• Early identification of fatigue-critical details

• Reduced fabrication and inspection complexity

• Improved constructability assumptions

• Lower downstream risk exposure
