SKF’s expertise in bearings has helped CorPower Ocean to optimise the design of a new class of wave energy converters, the company has announced.
Choosing suitable bearings for the new converter, which has slow rotation speeds and very high loads, was challenging. CorPower began with SKF’s Bearing Select online tool, as a first step to selecting the optimum bearing arrangements. The software, which is free to download, has been designed to simplify the task of finding the correct bearing solution for a particular design. Inserting operational parameters into the software automatically generates bearing solutions within one minute.
Because of the special conditions related to the wave power converters, CorPower needed more detailed bearings advice. SKF was brought into the project early – providing engineering support for the bearing solutions, as well as lubrication and monitoring systems.
“Our application engineers were involved at an early stage in the design process,” said Mattias Arstadius, Industrial Sales Unit Manager for SKF in Sweden. “This helped us to identify improvements that shorten development time, optimise performance and reduce costs.”
CorPower Ocean has now developed a first full-scale plant. This will be tested in the company’s dry-test rig over the summer, then placed in the sea off the Portuguese coast in the autumn. The company plans to launch a type certified commercial product on the global market by 2024.
