9:00 - 9:30 The risk of non-conventional soils on pile installation

Yiorgos Perikleous - Principal Geotechnical Engineer, DNV

• What are the foundation installation challenges faced by the industry (pile refusals, pile

runs, boulders, etc.)?

• Key lessons from installation in non-conventional soils: glauconitic sands, carbonate soils,

high strength glacial tills and intermediated soils.

• How well are we addressing installation risks?

10:00 - 10:30 Hybrid monopile foundation concept with drilled insert piles

Thomas Krusenstjerna Albæk - Head of Discipline - Primary Structures and Loads, COWI A/S

• Impenetrable soil conditions underlying soft soil conditions, caused for novel design solution.

• Innovative Design: Development of hybrid monopile foundations with drilled insert piles

with a diameter of 5.5 m.

• Extensive simulations to verify structural integrity during installation and in extreme conditions

• Material testing to extend the boundaries of grout applicability

• Certification achieved in 2023 with installation and commissioning completed in 2024

10:30 - 11:00 Refreshment Break and Networking

• How can XXL monopiles be driven efficiently while remaining within noise limits?

• A technical overview of available options (impulse, vibrations—axial

and torsional, push), their application areas, and associated challenges.

• Presentation of technical results from the Carbon Trust study (expected May 2025): “Gap

Analysis VLT vs Structural Integrity Design Guidance.”

13:00 - 13:30 Challenges when driving is not an option?

Paul Anthony Misic - Senior Engineer, Statkraft

• Driving into rock is an uncertain science

• Drilling is not a straight forward challenge

• Aspects not seen before as well as opportunities

• Selection of foundation concept is not necessarily based upon functional reasoning

15:00 - 15:30 Will the increase in WTG size (20-30MW) affect the T & I market??

Jeroen Berkhout - Project Director, Offshoretronic SL

• New WTG units with capacities between 20 and 30 MW, are set to debut in the market by

2029, what dimensions of Foundations should we expect.

• The advancement of larger WTG units will be propelled by significant cost reductions, but

is the supply chain ready for this shift.

• Highlighting the risks and challenges related to the T & I of larger Monopiles, which surpass

weights of 3,500 metric tons.

• Emerging markets can benefit from the lessons learned from the T & I issues and

challenges faced over the last 10 Years

Susanne Leidescher - Lecturer, International School of Management

Develop an understanding of future regulatory requirements and sustainable measures in the field of offshore wind along best practice examples:

- Regulatory developments (EU taxonomy, CSRD, CSRDDD, Omnibus package) 

- The future role of sustainability for offshore wind

- Social Equity strategies (multi-use, co-existing)

- Ecological measures (Nature Inclusive Design and nature positivity, circular concepts and decarbonisation options for the supply chain)
