Seagreen offshore wind farm
T&I Support
Seagreen offshore wind farm T&I Support
Seagreen is Scotland’s largest offshore wind farm (OWF) and the world’s deepest fixed-bottom OWF. Seagreen has 114 turbines with a total generating capacity of 1075 MW (Vestas V164-10MW Turbine) and it’s located 27 kilometers from the coast of Angus in the North Sea.
The scope comprised the transportation of the suction bucket jacket foundations (of around 2500tons) from fabrication yards in China and Dubai to Marshalling yard in Scotland using Heavy Transport Vessels (HTV’s). From the Marshalling yard, the jacket foundations are transported in Barges to the offshore installation site.
Lanza Engineers has provided FEM Engineering, Project Engineering and Field Engineering support during Structural design and Installation phases. This included, but not limited to:
- Strength capacity of the suction caissons during transportation for several grillage concepts
- Non-Linear elastic-plastic analysis and linear buckling eigenvalue analysis of the suction caissons during transportation
- Grillage & Sea fastening Structural review
- Grillage fatigue analysis during transport including hogging and sagging
- Load-out to HTV’s at ship yards using SPMT’s
- Load-in at Marshalling yard using SPMT’s
- Procedures for cutting, inspecting (incl. NDT) and repairing grillages between voyages
- Liaison with Yard, client, MWS and HTV crew for transporting of Cargo (Jackets)
- Load-out of jackets into barges for final Installation at site with Saipem 7000

EREBUS Floating Wind FEED Study
EREBUS Floating Wind FEED Study
The EREBUS project will feature between seven and ten 12MW offshore wind turbines on WindFloat® floating platforms located approximately 44 km southwest of the Pembrokeshire coastline in the Celtic Sea.
Lanza Engineers supported Principle Power during the Concept and FEED phases of the Erebus Project with the following engineering work:
- Grounding Analysis of the Floating Platform; this analysis consisted of a structural assessment to the primary structure of the WindFloat® floating platform during specific conditions.
- Dropped object simulation; this analysis simulates the impact of falling objects onto deck structures. Deck structures capacity to withstand and dissipate the energy from a dropped object is assessed in this analysis.
All the structural analysis mentioned above have been performed in ANSYS.
EFGL Floating Wind Engineering and Construction support
EFGL Floating Wind Engineering and Construction support
Les Éoliennes Flottantes du Golfe de Lion (EFGL) project features three 10 MW offshore wind turbines on three WindFloat® Floating Platforms, 16 kilometers from the coast of Leucate and Le Barcares in the French Mediterranean.
Lanza Engineers supported Principle Power during design and execution phase of the EFGL Project with the following engineering work:
- Global Strength Analysis (GSA) of the Floating Platform
- Global Fatigue Analysis (GFA) of the Floating Platform
- Detail Engineering of Secondary and Tertiary Structures on the Floating Platform
- Engineering support during fabrication stage
All the structural analysis mentioned above have been performed in ANSYS. All the post-processing of results was carried out with Python, Matlab and MathCad tools developed in-house.
Self Installing Platform (SIP) for Gas Offloading in Germany
Self Installing Platform (SIP) for Gas Offloading in Germany
Lanza Engineers supported KCI The Engineers performing a conceptual design of a Self-installing Regas Platform (SRP) to be used as an offshore LNG terminal in North Germany.
The structural assessment of the SRP was performed in SACS. In-place conditions analysis was caried out based on the preliminary information provided by the client.
The aim of this conceptual design included the assessment of the following systems:
- SRP’s leg guiding structure
- SRP’s jacking system capacity and integration
- SRP’s leg cross-section
- SRP’s leg cross beam and leg suction cans (foundations)
