Ocergy was founded by veteran offshore engineers who share the belief that clean ocean resources must be developed further to make our world more sustainable.

Alexia Aubault

Alexia is an offshore engineer, with a broad experience in all phases of design and execution of offshore projects. Most recently, Alexia was a VP of Engineering at Principle Power Inc. where, she was in charge of the WindFloat hull design for all projects which she followed from inception to fabrication and operation. As a structural engineer, she oversaw the detailed design of the hull in the fabrication yard near Lisbon, Portugal. At Principle Power, Alexia's team responsibility included developing inspection plans and performing in-situ inspections, where she developed a deep understanding of asset lifecycle management, especially in the area of remotely-operated platforms. Before focusing on offshore wind technology, Alexia had worked on a variety of offshore floating projects, in the wave energy industry as well as in the oil & gas, transport and tourism industries. She particularly enjoys R&D studies involving complex hydrodynamic calculations and model tests. She has published about varied subjects such as fluid-structure interactions, multi-body interactions in waves and has taught courses at conferences worldwide. Alexia is a graduate of ENSTA ParisTech and obtained a Master's of Science in Ocean Engineering at University of California, Berkeley.

Christian Cermelli

Christian’s career spans over 30 years of Naval Architecture and Offshore Engineering projects, including all phases of development from feasibility studies to project execution. He has acquired a vast experience in the design of floaters, such as semi-submersible, spars, TLP and ship-shaped vessels. He is co-inventor of the WindFloat technology developed by Principle Power, where he served as Chief Naval Architect during 5 years. Co-founder of Marine Innovation & Technology in 2003, he worked as technical lead on innovative projects involving offshore structures for several industries including renewables, oil&gas, transport, aquaculture. Previously, he worked with Shell International in Houston as a senior research engineer in the Floating Systems division. He obtained a PhD in advanced hydrodynamics from UC Berkeley in 1995, and is a registered professional engineer.

Dominique Roddier

Dominique is a Naval Architect consulting on a variety of ocean energy systems. For the last twelve years he served as Principle Power Chief Technology Officer, and Director. He is a co-inventor of the WindFloat. He obtained his doctorate in Naval Architecture from UC Berkeley, and after working in the offshore division of ExxonMobil’s Upstream Research Company co-founded Marine Innovation & Technology. Dominique is an expert in the design of floating structures and has interests in synergies between various ocean related technologies. He is actively involved in ASME and the OOAE division, under which he founded the IOWTC conference on offshore wind. He is a Fellow member of SNAME, serves as associate editor of multiple journals and has published and reviewed extensively. He also serves on multiple boards and / or advisory panels related to ocean resources, sustainability and related technologies. On his spare time, he is an avid sailor and enjoys swimming, skiing and biking actively.

About our logo

Our logo represents the letters OCG (short for Ocergy)
It also represents the spherical earth, made mostly of oceans.
Finally it embeds a breaking wave reflective of complex hydrodynamics, and growing plants as keeping the oceans clean will keep the earth healthy, peaceful and happy.
