Technology breakthrough in offshore wind design analysis

Now Fedem Technology and DNV Software have joined forces with a new coupled analysis module available in Sesam Wind – used when performance of the wind turbine is influenced by wave loading.

The offshore wind turbine industry will benefit from this new and innovative, user-friendly software solution including dynamic simulations, advanced fatigue calculation and code check in one complete analysis package. The new module for coupled analysis is powered by FEDEM Windpower, and is well integrated with Sesam. It is the most recent addition to DNV Software’s product portfolio in Sesam Wind.

“It saves costs by optimisation of wind turbine design and work processes,” says Svein Gjølmesli, Fedem Technology’s Software Manager, about the fully integrated analysis system.

Sesam Wind Coupled Analysis powered by FEDEM Windpower has capabilities ranging from the purely mechanical aspects of a wind turbine to customisable control systems and detailed wind and wave load simulations. This makes Sesam Wind a versatile software package for complete dynamic modelling and analysis of any wind turbine project. Through optimisation of wind turbine design and work processes, the industry will be able to increase efficiency and save cost.

With the new module, Sesam Wind incorporates state-of-the-art algorithms geared toward structural analysis, completing DNV Software’s solutions for wind turbine design, strength and fatigue analysis. Many different users – from substructure designers and turbine manufacturers to wind park operators and verification bodies – will benefit from the new package.

“The demand for renewable energy is growing rapidly and offshore wind is a significant part of renewable energy sources. Offshore wind installations are facing the same structural integrity challenges as traditional offshore engineering with structural design, hydrodynamic loads, global stresses and fatigue. In addition there are challenges with loads generated from the turbine itself and turbine rotor blades. As offshore wind is moving into deeper waters, engineering of offshore wind installations will take full benefit of Sesam, whether the installation is based on fixed structures, floating structures, shallow waters or deeper waters. With its leading position within offshore engineering, the offshore wind segment is a natural part of the Sesam strategy going forward,” says Are Føllesdal Tjønn, Managing Director at DNV Software.
