This year’s 2018 OMAE Short Course offering will consist of the following topics and speakers:

WEC Design Practices and Tools

Saturday, June 16th, 2018 – 9:00am-5:00pm

Dr. Ryan Coe, Dr. Yi-Hsiang Yu, and Kelley Ruehl
Senior Research Engineer (Coe), Sandia National Laboratories;
Senior Research Scientist (Yu), National Renewable Energy Laboratory;
Senior Research Engineer (Ruehl) Sandia National Laboratories.

While similar in many ways to other ocean systems, wave energy converters (WECs) pose a number of novel design challenges. This course reviews several considerations related to design and operation of wave energy converters and demonstrates a series of design tools/methods. Fundamentals of hydrodynamics, power take-off (PTO) systems, and implementation of controls for WECs are presented and the complete WEC system will be model from wave to wire. Best practices for designing experiments and performing system identification to obtain numerical models for WECs will also be discussed. The course also covers background and practical considerations for WEC design optimization as well as design load analysis for WEC system and components. 

Dynamics and Vibrations in Offshore Structures

Saturday, June 16th, 2018 – 9:00am-5:30pm

Dr. Junbo Jia, Prof. Bernt Johan Leira
Engineering expert (Jia); Professor, Department of Marine Technology (Leira)
Aker Solutions (Jia), Norwegian University of Science and Technology (Leira)

An understanding of the principles of structural dynamics and vibrations is important for assuring system integrity and operational functionality in different engineering areas. However, practical problems regarding dynamics are in many cases handled without success, despite large expenditures of investment. It is essential in approaching dynamic analysis and design that one develops an “intuition” to solve the relevant problems at hand; both academic knowhow and professional experience play equally important roles in developing such intuition.

To meet the objectives above, this course aims to address a wide range of topics in the field of offshore structures, starting from fundamentals and moving on to relevant and practical engineering challenges and solutions. Topics covered will include (i) engineering failures due to inappropriate accounting of dynamics; (ii) Newtonian dynamics and stochastic dynamics; (iii) nonlinear dynamics; (iv) characterizing environmental loadings and responses; (v) dynamics in assessing different limit states (extreme, fatigue, etc.) (vi) vibration mitigation measures. Special emphasis is placed on engineering applications that utilize state-of-the-art knowledge, the finite element method, relevant codes, probabilistic methods, and recommended practices.

Numerical and Experimental Dynamic Analysis of Offshore Wind Turbines

Sunday, June 17th, 2018 – 9:00am-5:00pm

Dr. Erin Bachynski
Associate Professor
Norwegian University of Science and Technology

This course reviews several considerations related to design and operation of offshore wind turbines. Fundamental concepts in aerodynamic (with focus on blade element/momentum theory) and hydrodynamic (with focus on first and second order radiation-diffraction and Morison-type models) load calculation are presented. The course addresses theoretical background and important practical considerations for structural response analysis combining these load components and wind turbine control for ULS and FLS design check. A review of the state of the art and challenges in experimental campaigns related to wind, wave, and ice loading for fixed and floating offshore wind turbines is also provided.
