Digital Twin Technology Improves Offshore Wind Jacket Design
Akselos and Lamprell have announced the results of an EU-backed wind foundation design project, proving that predictive digital twin technology can reduce the steel weight and associated costs of offshore wind jacket foundations by up to 30%. The European Union awarded Akselos E1.4 million in 2018 to conduct the research and pilot project GODESS - Global Optimal Design of Support Structures. The GODESS philosophy has been used as the basis for proof of concept on one of Lamprell’s UK offshore wind projects. Lamprell will now apply the findings to reduce the amount of steel it uses to construct its offshore foundations.
The results were achieved thanks to Akselos’ MIT-licensed simulation technology reduced basis finite element analysis (RB-FEA), that allows for speed and accuracy through real-time data feeds. For Lamprell, that enables highly accelerated design workflows where multiple design alternatives can be tested against thousands of scenarios in minutes, and in high fidelity.
The research will continue by creating a full digital loop from design to operations, the companies said. This brings together parametric simulations, machine learning, and optimization routines to enable engineers to use relevant operational data to understand how designs behave under operating conditions, allowing for resilient, optimal designs based on real-world data.
Lamprell is also applying the technology to the design of oil and gas installation foundations. So far, the company has seen a 10% reduction in weight.
The research was conducted with Eurostars, which is co-funded by the State Secretariat for Education, Research and Innovation and the EU.
