COURSE OVERVIEW:

Offshore Structural Analysis: Wave, Wind and Current Loading Fundamentals is an advanced engineering program focused on the environmental forces acting on marine structures. This course examines the physics of fluid-structure interaction and the mathematical models used to predict the behavior of platforms under extreme conditions. It provides a technical framework for understanding how kinetic energy from the ocean and atmosphere is transferred into structural stress and displacement.

The scope of this training involves the detailed study of wave theories, including Linear (Airy) and Non-linear (Stokes) models, as well as the application of Morison’s Equation for calculating hydrodynamic loads on slender members. Participants will explore the mechanics of wind-induced vibrations and the impact of steady-state and tidal currents on subsea components and jacket legs. The program emphasizes the importance of "Return Periods" (e.g., 100-year storm) in defining the design basis for offshore assets.

Coverage includes the analysis of "Vortex-Induced Vibrations" (VIV), wave slamming forces, and the cumulative effects of fatigue loading over a structure's lifecycle. The course addresses the integration of MetOcean data into structural simulation software and the validation of theoretical models through empirical observations. By mastering these loading fundamentals, offshore structural engineers will be equipped to design resilient facilities that withstand the harshest maritime environments.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

1. Define the fundamental characteristics of wave, wind, and current forces.
2. Apply Linear and Higher-order wave theories to structural design problems.
3. Calculate hydrodynamic forces using Morison’s Equation and Diffraction theory.
4. Analyze the impact of wind profiles and gust factors on topside structures.
5. Evaluate the effects of current-induced drag and lift on submerged members.
6. Identify the risks of Vortex-Induced Vibrations (VIV) in risers and pipelines.
7. Interpret MetOcean data for the selection of design wave heights and periods.
8. Assess the impact of wave slamming and slap on horizontal structural members.
9. Perform spectral analysis for irregular sea states using standardized wave spectra.
10. Calculate the "Base Shear" and "Overturning Moment" for offshore platforms.
11. Predict long-term fatigue damage resulting from cyclic environmental loading.
12. Design structural reinforcements to mitigate extreme environmental stress.
13. Lead the technical review of environmental load assessments for new projects.

TARGET AUDIENCE:

Structural Engineers, Naval Architects, Offshore Design Leads, and Research and Development Specialists.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximise the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
