About us

History

Sebastian AS was founded in 1994 with a clear mission: to deliver expert consultancy services that empower clients worldwide. From our offices in Norway, Brazil, and China, we provide innovative solutions tailored to the evolving needs of the maritime and energy industries.

Our journey began with engineering services for offshore service vessels, partnering with local shipyards and design companies. By 1998, we were delivering FMEAs and FMECAs globally, establishing ourselves as trusted experts in complex technical analysis.

Joining IMCA in 2005 and MTS in 2014 cemented our reputation for excellence, while our membership in NORWEA and the Norwegian Offshore Wind Cluster in 2022 marked our commitment to shaping a sustainable energy future.
For over three decades, our expertise has been trusted by clients navigating the Maritime, Oil & Gas, and renewable energy sectors. Built on a foundation of technical precision and a forward-thinking mindset, Sebastian AS remains dedicated to delivering solutions that meet today’s challenges while anticipating tomorrow’s needs.

As we continue to grow, we are proud to be a reliable partner, offering innovation, integrity, and a global perspective to every project we undertake.
