Hydrodynamic Design Optimization and Wave Tank Testing of Self-Reacting Two-Body Wave Energy Converter
… wave energy converter is tested in a wave tank. The results of the wave tank tests show that the two-body wave energy converter can absorb nearly twice the energy of a single-body 'point absorber' type wave energy converter.

An experimental investigation into the most prominent sources of uncertainty in wave tank testing of floating offshore wind turbines
… offshore wind platforms must undergo wave tank testing in the early stages of development to assess model responses to different wave and wind conditions. Wave tank testing, while highly beneficial, is liable to errors arising throughout the testing campaign. Errors can arise during wave …

Experimental and Numerical Modelling of a Multiple Oscillating Water Column Structure
… of the proposed platform is described, and a tank testing programme for the model, in a variety of configurations, is outlined. A frequency domain, numerical model of the physical scale model is developed. Predictions from the numerical model are compared to the tank testing results. Based on …

DYNAMICS OF A SUBMERSIBLE MUSSEL RAFT
… submersible mussel raft were analyzed using wave tank testing, numerical modeling, and full-scale field tests. When submerged, the raft’s pontoons are flooded, and it is held vertically by lines attached to surface floats and horizontally by a spread mooring. This submerged configuration is used …

Autonomous data collection techniques for approximating marine vehicle kinematics
… using in-field online techniques rather than tow tank testing or Computational Fluid Dynamics (CFD). While the parameters of many physical dynamic models can be obtained using System Identification (SI) techniques, these models require knowledge of the vehicle actuators, which may not be the case …

An investigation into the design of surface piercing super cavitating hydrofoils
… against empirical results obtained through tow tank testing at higher cavitation numbers. The analytical and empirical validation bound the range of cavitation numbers considered in this study from [sigma]= 0.05 to [sigma]= 2.37.

Performance and hull pressure analysis of scaled physical testing of a wave energy converter
… process. For this reason, small-scale tank tests and computer modelling of concepts are vital to develop wave energy converter technologies to the highest possible degree before being put into an open-water operational environment. This study describes a physical tank testing campaign …

Development of computational and experimental techniques to Investigate the effect of biofouling on ship hydrodynamic performance
… I includes experimental validations by means of tank testing to demonstrate the suitability of the methods for the added resistance prediction due to hull roughness: Granville's similarity law scaling method and the CFD method involving modified wall-functions. Part II presents the full-scale …

Challenges in the design of tension moored floating wind turbines
… simulations and experimental wave basin tank testing. Design improvements in an existing platform, HEXWIND, are identified, leading to the design of a novel platform, TWind. As tension moored platforms are highly constrained in heave, pitch and roll motions, a significant coupling and …

Evanescent Wave Reduction Using a Segmented Wavemaker in a Two Dimensional Wave Tank
… are created by the wavemaking process during tank testing. They have long been a nuisance for engineers as they contaminate the wave field in the tank and result in additional inertial force experienced by a wavemaker. Evanescent waves are created by the mismatch between the motion of the …

Feasibility of combined wind-wave energy platforms
The European Union has set out an ambitious 20% target for renewable energy use by 2020. It is expected that this will be met mainly by wind energy. Looking towards 2050, reductions in greenhouse gas emissions of 80-95% are to be sought. Given the issues securing this target in the transport and …
