Overview
The Offshore Engineering Society is delighted to invite you to this lecture on wind structures. This presentation will be led by Nicholas Epiphaniou, the principal structural engineer at Sapiem, with over 14 years of experience focused on numerical simulation and structural integrity assessment of offshore structures.
This presentation will cover fatigue analysis using multiaxial assessment for fixed and floating wind turbine substructures.
It outlines Saipem's approach to semi-submersible floating wind platforms, discusses modelling capabilities, control systems, dynamic loading, and emphasises the importance of multiaxial assessment in optimising design.
Sapiem is a world leader in engineering and drilling activities and in the development of major projects, in the energy and infrastructure sectors.

Nicholas Epiphaniou
Nicholas is a principal structural engineer at Saipem with over 14 years of experience focused on numerical simulation and structural integrity assessment of offshore structures.
He has worked on numerous design projects involving complex finite element modelling of wind turbine structural assemblies and components. His contributions to the HyWind Project, specifically the mechanical/structural design of the stability frame systems, were instrumental and led to the system receiving the prestigious Innovation Award for Structures in Extreme Conditions from IStructE - Structural Awards 2018.
Nicholas has played a key role in the development of efficient processes for time-domain fatigue assessment of offshore renewable energy structures for WTG fixed foundations. Specifically, he focused on fatigue assessment using influence matrix methodology and force superposition.
Within Saipem' structural group, Nicholas persistently refines and advances these methods for evaluating both fatigue limit state (FLS) and ultimate limit state (ULS) in floating wind substructures.
