What we do
We are a technology, design and engineering company with focus on our unique cylindrical hull design.
Focus areas
Sevan has been an innovator within floating offshore structures for more than 20 years. In addition to oil & gas activities, we are now developing concepts for the green and renewable energy markets based on our cylindrical hull. We have a strong focus on digital solutions and how to use these in our design and engineering work and to aid the operation of floating units.
Concept Development
We develop concepts for a wide range of floating applications, and further customize the designs according to client and site-specific requirements.
Development starts with informal discussions with the client and progresses in steps where each study phase brings the client closer to an optimized solution ready for a final investment decision and construction start.


Engineering
Taking an idea through all the steps from the whiteboard to realisation, requires a wide range of knowledge and experience. Sevan is involved in all these steps, but we are focusing on some core disciplines where we try to be best in class.
Within these core disciplines, you will find highly skilled engineers performing advanced analysis to support their decisions and design solutions.

Research and Development
Sevan is doing internal research and model testing of potential new concepts. We are also participating in external R&D programs at research institutions or together with other industrial partners.
We are continuously developing our “inquire” system which is used for integrity monitoring and operational advice for floating units and also used to improve engineering efficiency and quality


EPC Execution Model
One stop solution including early design phases, FEED, EPC and Installation can be offered together with our parent company Seatrium.
Sevan has a flexible execution model. We try to support client’s individual preferences, so alternatives to the one stop solution are available.

Marine Operations
Sevan has extensive in-house experience with transportation and mooring of floating units.
We can assist in the planning and execution of marine operations.

Operational Support
Sevan can provide general problem solving and engineering assistance during operation.
We can also offer integrity monitoring of the mooring system and advice on operation to minimize maintenance and maximize lifetime.

Re-deployment
We are happy to note that the Sevan units are popular re-deployment candidates.
The Sevan specific experience, knowledge and capacities described in the above sections makes us a preferred partner for re-deployment or conversion of a Sevan unit.
We have moved, modified and re-deployed Sevan units and will assist our existing and new clients in future projects.
