Abstract

Physical wave basin tests with a focus on uncertainty estimation have been conducted on a fixed sphere subjected to wave loads at Aalborg University as part of the effort of the OES Wave Energy Converters Modelling Verification and Validation (formerly, OES Task 10) working group to increase credibility of numerical modelling of WECs.
The present note defines an idealized testcase formulated to accurately represent the physical tests in a simple way. The testcase consists of a fixed, rigid sphere half submerged in water subjected to regular waves of three different levels of linearity. The objective of the present note is to allow for numerical tests of the idealized testcase.
