Abstract. This paper provides a summary of the work done within Phase III Offshore Code Comparison Collaboration, Continued, with Correlation and unCertainty (OC6) project, under International Energy Agency Wind Technology Collaboration Programme Task 30. phase focused on validating aerodynamic loading wind turbine rotor undergoing large motion caused by floating support structure. Numerical mo...

The motion of water or the atmosphere that surrounds or supports a mobile platform affects the motion of the platform in a favorable or unfavorable way. Exploiting and compensating the ambient field is investigated for different motion objectives like the classical point to point motion, observation motion, exploration motion and so-called survival motion. Time and energy optimal trajectories i...

Given the worldwide industry progress in the construction of massive concrete structures, it would be a good idea to use concrete gravity base structures (GBS).In this regard, better understanding of thesestructuresregardingtheiradvantages and disadvantages in offshore areas seems necessary.The present study employed MacCammy-Fuchs method, which is based on the size of the structure to the wave...

Mobile robotic systems, which include a mobile platform with one or more manipulators, mounted at specific locations on the mobile base, are of great interest in a number of applications. In this paper, after thorough kinematic studies on the platform and manipulator motions, a systematic methodology will be presented to obtain the dynamic equations for such systems without violating the base n...

Abstract. Floating offshore wind turbines may experience large surge motions, which can cause blade–vortex interaction if they are similar to or faster than the local speed. Previous research hypothesized that this phenomenon represented a turbulent wake state even vortex ring state, rendering actuator disc momentum theory and blade element invalid. This hypothesis is challenged, we show valid ...

Respiratory motion continues to present challenges in the delivery of radiation therapy to tumors in the thorax and abdomen by causing movement of structures within those areas. Several approaches to account for this movement in the planning and delivery of treatment have been developed over the past several years. To assist in the development and assessment of various techniques for respiratio...
