The future of offshore wind lies in wind farms that float on ballasts and moorings, with the cables laid directly on the seafloor. Floating wind farms are a great solution when wind farms situated just off the coast grow crowded. They can also take advantage of the bigger and more powerful winds that occur further out to sea. Floating wind farms are expected to grow more popular over the next decade. This is an especially attractive option for areas like the Pacific Coast of the United States and the Mediterranean, where the shores are deeper, as opposed to the shallow waters of the Atlantic Coast of the U.S., U.K., and Norway. One important requirement of floating OFW farms is the installation of dynamic, high-capacity submarine cables that are able to effectively harness and deliver the generated electricity to our shores.

Before fixing or installing a submarine cable, which can cost billions of dollars, cable designers have to ensure that designs will perform as intended in undersea conditions. Today, this is typically done with the help of computational electromagnetics modeling. To validate cable simulation results, international standards are used, but these standards have not been able to keep up with recent advancements in computational power and the simulation software’s growing capabilities. Hellenic Cables, including its subsidiary FULGOR, use the finite element method (FEM) to analyze their cable designs and compare them to experimental measurements, often getting better results than what the international standards can offer.

“The model helps predict how heat and humidity inside a powder bed fusion factory may affect product quality and worker safety,” says Adam Holloway, a technology manager within the MTC’s modeling team. “When combined with data feeds from our facility, the app helps us integrate predictive modeling into day-to-day decision-making.” The MTC project demonstrates the benefits of placing simulation directly into the hands of today’s industrial workforce and shows how simulation could help shape the future of manufacturing.

The team made their model more accessible by building a simulation app of it with the Application Builder in COMSOL Multiphysics. “We’re trying to present the findings of some very complex calculations in a simple-to-understand way,” Holloway explains. “By creating an app from our model, we can empower staff to run predictive simulations on laptops during their daily shifts.”
