DEVELOPMENTS IN FOUNDATION TECHNOLOGY
NORWEGIAN OFFSHORE EXPERIENCE BENEFITS THE WIND ENERGY INDUSTRY
Sesam software revolutionised the offshore industry with its finite element methodology when it was brought to the marketplace more than 40 years ago.
RELIABILITY COUPLED WITH PIONEERING TECHNOLOGY It has through the years combined stable reliability with pioneering new technology for strength assessment of offshore structures. DNV Software’s Sesam Wind solutions bring together decades of DNV experience, both in the offshore industry and in the global wind energy industry.
INTEGRATED DESIGN ANALYSIS AND STRUCTURAL INTEGRITY ASSESSMENT
Strength analysis of offshore wind turbine structures needs to account for the combined effect of wind and hydrodynamic loads. The system integrates design, analysis and structural integrity assessment, covering the entire lifecycle of a structure. Its fully-coupled dynamic analysis of an integrated wind turbine system is unique.
This includes wind turbine, substructure/ foundation and environment loads including fatigue and ultimate strength analyses of the substructure. It can also accurately model the complex transition structure between the wind tower and the supporting structure. The software can be utilised during various phases of the wind turbine’s lifecycle, from design through installation to operation and maintenance.
COVERING ALL ASPECTS
The system allows wind turbine structures to be designed for every depth, from shallow water monopiles to tripods and jacket structures as well as concrete gravity based structures for larger depths. This is done with one single model and within one complete system covering all aspects of offshore installations, with imports from other systems easily integrated.
The Sesam Wind Coupled Analysis module for all wind turbine components is powered by FEDEM Windpower. Fedem Technologies – a player in the wind industry based in Trondheim, Norway – has entered a partnership with Oslo-based DNV Software.
