Challenges in Deep Water Experiments: Hybrid Approach

Abstract

An overview of challenges within hydrodynamic verification of deep-water offshore structures is given first. The role of model testing in the verification, as well as a range of relevant measured responses, are discussed. Various solutions for experimental verification of deep-water structures are considered. In particular, the combination of model tests with truncated set-up and computer simulations—the hybrid approach—is discussed. Two basic groups of hybrid methods are identified: Active (on-line) and passive (off-line). Most published works are on passive systems, of which a particular method is described. Case study examples with this procedure are reviewed and discussed, and future challenges are commented.
