Minimise monopile mass with integrated loads analysis

Monopiles can be modelled and analysed directly in Bladed, and the output member loads processed for simple structural checks. This analysis fits easily into design optimisation routines to reduce steel mass and foundation cost.

The analysis couples important effects together, such as:

  • Aerodynamic loads and structural response
  • Nonlinear pile-soil interaction, including support for PISA approach
  • Environmental loads like earthquakes and non-linear waves
  • User-defined external applied loading such as for breaking waves

Rapid iterations to optimise your jacket design

Reach the final and optimal jacket design more quickly using Bladed’s two seamless workflows for coupled analysis.

  • Integrated workflow: Import the full jacket geometry details into Bladed, to enable effects such as non-linear soil stiffness to be included in the coupled analysis. Seamless interfaces to Sesam enable easy jacket definition and structural analysis.
  • Superelement workflow: A superelement embodies complex structural data about the jacket properties and hides sensitive intellectual property. Import a support structure superelement file from popular tools like Sesam, Sacs or ROSAP.

Minimise foundation design uncertainty with accurate turbine models

Using an accurate model of the turbine from the early project stages .

  • For early analysis and research, use the IEA 15 MW and IEA 22 MW reference turbine models supplied with Bladed.
  • For preliminary analysis use DNV concept models that are representative of real turbine designs, including a commercial quality controller.
  • For detailed design, Bladed's encryption technology allows the turbine manufacturer to share their model with the foundation designer.

Extend jacket fatigue life with detailed joint modelling

A more refined approach to joint modelling can increase fatigue life estimates, which is particularly valuable when it comes to foundation life extension.

Bladed can include structural elements such as local joint flexibility and member end offsets. This reduces conservative loading and structural assumptions, resulting in lower stress concentration at beam ends.

Ensure structural integrity during seismic events

Offshore wind turbines are being deployed in seismically active regions such as Japan and Taiwan. Seismic loads must be simulated accurately and according to local design standards, to ensure structural safety and reduce unnecessary design conservatism and cost.

Bladed generates synthetic earthquake acceleration time histories, which are applied in a simulation. The non-linear interaction between turbine, support structure and soils during an earthquake are analysed in either the integrated or superelement approaches.

Automate processes and simulate at scale

Offshore wind simulations must consider many combinations of sea and wind conditions, resulting in 1000s of time domain simulations, which is a computationally demanding process.

Bladed supports you with this by providing:

  • Scripting API interfaces to automate calculation setup and processing
  • Bladed Cloud scalable compute service
  • Flexible licensing solutions for your own cloud or on-premises compute setup
  • Compute on Windows and Linux
