Frequently Asked Questions
What is a reference model for offshore wind turbines?
Jason Jonkman et al. (2009) defined a 5-MW reference wind turbine as a three-bladed, upwind, variable-speed, variable blade-pitch-to-feather-controlled multimegawatt model developed by NREL. This model supports concept studies assessing offshore wind technology. It has received 5710 citations for standardizing offshore system development.
What technologies are used in wave energy conversion?
Wave energy utilization involves power take-off systems and various converters reviewed by A.F.O. Falcão (2009) with 2563 citations. Benjamin Drew et al. (2009) detailed wave energy converter technology, driven by renewable energy targets. These systems extract energy from ocean waves, a largely untapped resource.
How are wave forces calculated on offshore structures?
J. R. Morison et al. (1950) formulated wave force on piles as drag proportional to velocity squared plus inertia components, cited 2552 times. This applies to cylindrical objects from seabed to above wave crest. The model remains fundamental for offshore pile design.
What is hydrodynamic modeling in wave energy systems?
Hydrodynamic modeling covers linear-wave induced motions, second-order non-linear problems, and viscous loads as detailed in Odd M. Faltinsen (1990) 'Sea Loads on Ships and Offshore Structures' with 2260 citations. Robert G. Dean and Robert A. Dalrymple (1991) introduced classical water wave theory for engineers in 'Water Wave Mechanics for Engineers and Scientists'. These provide self-contained derivations for floating structures and wave power applications.
