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?

9:30 - 10:00 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

• 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.”

11:30 - 12:30 Low-noise foundation installation technology developments at Ørsted

• Suction bucket jackets: experiences from offshore installations.

• Novel low-noise monopile installations: advances using jetting technology

• Future outlook

12:00 - 12:30 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

12:30 - 14:00 Lunch Break and Networking

14:00 - 14:30 Noise modelling - sound predictions and noise mitigation

14:30 - 15:00 Tackling Pile Run: Causes, Lessons Learned, and Potential Solutions for Offshore Foundation Installation

Pooyan Ghasemi - Lead expert, RWE

• Pile Run: Causes, predictions, and mitigation strategies

• Lessons Learned: Insights from two North Sea projects

• Vibratory Driving: Evaluating its feasibility as a solution

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

15:30 - 15:30 End of Focus Day

16:00 - 17:00 Workshop A | Sustainability in Offshore Wind – Regulatory Trends and Industry Impact

Susanne Leidescher - Senior Consultant Business Intelligence & Sales, Ramboll

Develop an understanding of future regulatory requirements and sustainable measures in

the field of offshore foundations

• Regulatory Developments

• Overview of existing sustainability regulations (EU Taxonomy, ESG guidelines, carbon

footprint assessment)

• Expected future requirements for offshore foundationsImpacts on design, production,

and recycling strategies3.

• Sustainable Materials and Production Processes

• Options for reducing the carbon footprint (e.g., green steel, alternative materials)

• Sustainable procurement and supply chains

• Recycling and circular economy concepts for foundations

17:45 - 18:45 Workshop B | Monopile Stiffness, Damping & Cyclic Deformation

• Why do we still don’t get a match between measured and calculated natural frequencies?

• Can we now quantify damping contributions from Monopiles and should it be frequency

dependent?

• Should we model the stiffness of monopiles linearly or nonlinearly?

• What about cyclic accumulation of displacements?

18:30 - 19:30 Workshop C | AI in Offshore Foundation Design
