Pre-FEED and FEED offshore wind

AF Gruppen supports offshore wind developers with Pre‑FEED and FEED studies for both floating and fixed‑bottom concrete solutions. Offshore wind projects are complex, and many clients need clear, practical guidance to move safely from early concepts into execution. That is where AF brings value.

Our studies focus on buildable, cost‑effective and sustainable solutions, combining engineering insight with hands‑on construction and port experience. We help clients make informed decisions early, reduce risk and prepare projects for efficient delivery.

Our scope typically includes:

• FEED (Front-End Engineering Design) studies for EPCI projects
• Concept design
• Tower–foundation interface studies
• Fabrication strategy and constructability
• Load‑out and logistics
• Cost analysis
• Environmental accounting
• Testing and documentation of new concrete mixes
• End‑of‑life strategy – reuse, decommissioning and recycling

Through robust cost analysis and environmental accounting, we give clients a clear understanding of CAPEX, risks and CO₂ footprint. Our concrete expertise includes testing and documentation of new and innovative mixes, supporting long service life and reduced emissions.

AF Gruppen also brings strong competence in port infrastructure and logistics, ensuring that proposed solutions are realistic and executable. This integrated approach helps reduce greenhouse gas emissions, avoid delays and deliver real financial benefits for offshore wind projects.
