The most comprehensive software for strength assessments
Sesam is a life cycle management system delivering strength assessment and operational management from design to operation to decommissioning. Sesam covers a structure's entire life cycle delivering engineering software support in design, structural re-analysis systems, modifications and repair, input to the operational phase, emergency response and decommission.
Using concept technologies in computer aided engineering has proven to be cost-efficient in all the design phases, since the same concept model can be used with different complexities.
Market driven development
While Sesam has evolved as a market-driven modular system enabling users to invest in a package of selected modules, integrated packages have also been developed to cover specific needs.
This allows for tailor-made Sesam installations to maximise features in a cost-efficient way. The packages share a common look and feel, which makes the system intuitive and easy to learn. All packages cover in-place, installation, transportation, accidental conditions and operational aspects.

DNV has developed routines and software for ensuring life extension of offshore installations.
For some offshore fields it is necessary to extend the life expectancy by 50–100%; it is vital to make sure that
installations can sustain this extra time without compromising on safety.

DNV has a lot of experience relating to inspection and life cycle analysis of offshore structures. Based on this knowledge, Sesam Structure Integrity was developed; the first official version was released in 2005, and DNV Software has since then continuously invested huge efforts in enhancing its capabilities.
