Currently, the design of floating offshore wind systems is primarily based on mid-fidelity models with empirical drag forces. The tuning model coefficients requires data from either experiments or high-fidelity simulations. As part OC6 (Offshore Code Comparison Collaboration, Continued, Correlation, and unCertainty (OC6) a project under International Energy Agency Wind Task 30 framework) projec...

As offshore exploration and development of oil fields reach water depths of 1,000 to 3,000 m, novel methods of anchoring production platforms become attractive due to cost savings associated with installation. Surface production systems that are viable in these water depths include Tension Leg Platforms (TLP), spar platforms, and laterally moored ship-shaped and semisubmersible vessels. Possibl...

There is an increasing demand for high-resolution recording of in situ underwater cultural heritage. Reflectance transformation imaging (RTI) has a proven track record in terrestrial contexts for acquiring highresolution diagnostic data at small scales. The research presented here documents the first adaptation of RTI protocols to the subaquatic environment, with a scuba-deployable method desig...

This study predicted the motion response and power performance of a floating wind turbine system equipped with semisubmersible Taida platform, an IEA 15 MW turbine, 3 × 2 mooring design in Hsinchu offshore area Taiwan Strait. The hydrodynamic properties were calculated using ANSYS-AQWA STAR-CCM+. equations solved by OrcaFlex to obtain generator power, as well dynamics aerodynamics turbine. wave...

Ocean energy is an underutilized renewable source compared with hydropower and wind power. Therefore, the development of economical efficient wave converters (WECs) important crucial for offshore power generation. The mooring tensioner a critical device that can be used in point-absorber-type WECs, semisubmersible floats oil gas drilling, floating turbines. A system to create, reduce, or mainta...
