Offshore jacket structures have been used for building oil and gas infrastructure for decades. The existing jackets are typically designed for a life of around 20 years. Improvements in oil recovery from several fields have increased the interest in using these structures well beyond their initial design life. Even though large re-constructions, repairs, and inspections have been performed, using existing installations beyond their design life will, in many cases, be economically preferable. Recently, jacket type of structures are used as foundations for wind turbines. For these, non-linear boat impact analysis are important and push over analysis may be needed to optimize the design.

In this recorded three-part demo series you will get insights into:

Basics to pushover analysis
How to include deformations and damages to members
Strategies to perform Non-linear Analysis
Executing non-linear analysis and investigating the results

Part 1: Introduction to non-linear analysis

Create a model in Sesam GeniE
Run non-linear analysis in Sesam Usfos
Understand and inspect non-linear results

Part 2: Introduction to collapse analysis of jacket structures

Create and execute collapse analysis using Sesam GeniE/Usfos
Add deformations and damaged members
Add ductility and fracture criterion
Execute joint code check analysis

Part 3: Introduction to boat/ship impact analysis and dynamic time domain analysis.

Create boat impact inputs and execute boat impact analysis
Execute multiple boat impact analysis
Perform a dropped object analysis

The presentations and demonstrations are given by Abin Thomas, Principal Engineer. He has been working in the Design and fabrication of Offshore platforms since 2007, and holds a Master’s degree in Structural Engineering and is an expert in the field of Finite Element and Non-linear Analysis of structures.
