About Floventis

In 2021 Cierco and SBM Offshore formed the joint venture company, Floventis Energy, with the goal of becoming a market leader in offshore floating wind power. The joint venture brings together complementary skills and expertise to produce the know-how required to develop and deliver complex technology projects successfully in the offshore environment.


Our strategy is simple. We plan to maximize the local benefits of our projects and minimize their impact. Our technologies are far more benign than conventional offshore wind and more suited for deployment in remote and sensitive environments.

Already driving demonstration projects in California and the UK, Floventis is building a portfolio of projects to take floating offshore wind, through a stepwise process – increasing project size, to full scale commercial development proposals by 2030.

We believe that the floating offshore wind industry is a model for a “just transition” to clean energy, at scale, which will reward communities, in the broadest sense, with skilled jobs and enhanced social equity.


Through our team, we have a wide international network, allowing us to resource ourselves to meet project needs and challenges. We can provide a broad range of offshore wind management activities.

Cierco is an independent renewable energy project development company. It was established in 2001 with a simple goal – to engage in the field of offshore wind power and to drive technologies and projects that would compete with directly with the cost levels of conventional power. Cierco uses its expertise to identify which innovative technologies will maximize economic and environmental benefits in any given location.

SBM Offshore is a world leader in floating offshore energy. It takes projects, from design and supply to installation and operation, extending products’ lifespan wherever possible. Its ability to harness energy on, in and below the world’s waters positions it as a global leader in renewable energy development. As we transition from oil and gas to wind and wave, SBM Offshore is uniquely placed to drive the changes needed.

Leadership Team

Our team, connects us to a global network of expert partners. This allows us to source precisely the right people to meet specific project needs and challenges. Consequently, we can provide an exceptionally wide range of offshore wind management expertise, skills and services.

Mikael Jakobsson

Mikael founded CIERCO Corporation in 2001. His first offshore turbine started turning in 1989 and, over the past 33 years, he has built up an unrivalled knowledge of the wind energy sector, from development to deeper technology understanding as well as operational experience. Mikael has held senior management roles with some of the biggest and most progressive names in the business including Wind World, BTM, Tacke, Enron, EDF/Airicole and 2B Energy.

Scott Harper

Having a background in the Scottish National Economic Development Agency, Scott has been in the front line of multiple projects and acquired an exceptionally broad knowledge of the wind energy sector over the past 20 years. His skills include project development, managing technological innovation, undertaking strategic project planning and developing key markets. Scott is widely respected across the industry for his outstanding ability to get things done.

Olivier Morel d’Arleux

Over the past 20 years, Olivier has delivered many large-scale energy infrastructure projects including France’s Provence Grande Large wind farm. During that time, he has developed a wealth of experience and developed all of the financial, M&A, controlling and reporting skills need to facilitate floating offshore wind development.

Severine Baudic

Séverine rose to become Managing Director New Energies & Services in January 2021 and leads Renewables, Gas and Digital Services at SBM Offshore. As a hydrodynamics engineer, she has managed breakthrough technology projects. A graduate of France’s SeaTech School of Engineering, Severine has an MSc in Civil Engineering from the University of Houston.

Floating Wind

Offshore wind is now a cornerstone of the global effort to decarbonise electricity production. Floating Offshore Wind Power is set to revolutionise the offshore wind market over time. Because floating wind power is projected to be more cost effective than conventional offshore wind power, Floventis is focused on making it commercially competitive within the next decade.

The Floating Turbine

A floating wind turbine is, quite simply, a wind turbine mounted on a floating structure. This is a much more flexible solution than a fixed structure as its location is not limited by seabed depth or conditions.

There are over 30 different design concepts for the vessels that will carry the wind turbines.  Floventis is in the process of identifying the most promising of these. We will explore the options in different conditions, water depths and seabed locations to identify optimal solutions in each distinct environment

Floating wind projects offer significant opportunities for local economies as they require local involvement. Assembly, installation and ongoing maintenance operations, are undertaken in local harbours, where they create work and develop expertise

Local Impact

Floating wind projects offer significant opportunities for local economies as they require local involvement. Assembly, installation and ongoing maintenance operations, can be undertaken where local harbour infrastructure is available creating employment opportunities and building local expertise.

Floventis is committed to work with regional and local stakeholders to maximise the opportunity for ports and local businesses to support a sustainable economy.


Floventis operates in both the UK and US markets, with active involvement and contribution to the development of floating wind markets in both countries. We have adopted a strategic,  stepwise approach, enabling us to advance steadily into larger projects. We believe that a responsible and sustainable approach is key to the long-term success of the floating offshore wind industry, so it is fully integrated into our commercial ambitions. Our current project portfolio includes:


The Llŷr 1 and Llŷr 2 projects, comprising of two separate 100MW sites located south of Pembroke, on the UK’s Welsh coast.

The projects have all come forward through The Crown Estate’s Test & Demonstration leasing opportunity, created to support the development and commercialisation of pioneering, floating wind technologies. Each of the Llŷr projects will test new floating platform and mooring technologies and explore innovative designs, materials and construction approaches.

Visit the Llŷr project website


Situated off the coast of Santa Barbara in California, just west of the Vandenberg Space Force Base, CADEMO is a 60 MW demonstration project aimed at kick-starting the emergent marine renewables sector off the west coast of the United States. The project company, CADEMO Corporation, aims to have the project operational by 2026, providing a new source of renewable energy for the California market and a stepping-stone for large-scale commercial projects right along the Californian seaboard.
