Fitness for Service and Engineering - Critical Assessment of Pipelines and Structures

Pipeline

FFS/ECA course based on the latest DNV code revisions and software development

About this course
This course focuses on the practical application of FFS and ECA particularly for pipelines and structures. While BS7910 and API579 are essentially stress based codes, the course covers strain-based analyses of pipelines with girth weld flaws and provides an overview of different methods and software tools for analyzing the tensile strain capacity of pipelines subject to high strain. The course includes a brief introduction of finite element analysis (FEA) to determine the stress and strain input to the analysis and covers advanced flaw modelling and J-integral analysis to derive the crack driving force.

The course will cover the theoretical background for elastic and elastic plastic fracture mechanics and the fracture assessment diagram (FAD) methods, fatigue crack growth and tearing analysis. The course will also provide insight into the practical aspects of elastic plastic fracture toughness (CTOD, J-integral) testing of  weldments and the requirements to non- destructive testing for flaw sizing and development of alternative flaw acceptance criteria for pipeline installation. The first three days (Days 1-3) of the course cover applications involving high strain due to lateral buckling, reeling installation and high temperatures in clad pipelines as  well as the effect of fatigue loading due to vortex induced vibration (VIV) associated with free spans. The fourth day (Day 4) of the course, which is optional, covers an introduction of finite element modelling, definition of  boundary conditions and material models and finite element-based fracture mechanics analysis to generate stress/strain input to general design and ECA/FFS assessments.

Learning objectives
You will gain confidence in performing Option 1 and 2 analyses according to BS 7910: 2013 and will also be introduced to Option 3, which uses numerical analysis to generate a FAD and ductile tearing assessments. You will also become familiar with strain-based analyses based on DNV GL-RP-F108 : 2017, BS7910:2019 Annex V and alternative methods.

Target group
The course is aimed at welding, inspection, structural, mechanical, construction, design and maintenance engineers who require more knowledge of the application of FFS assessment methods for structures, piping/pipelines and pressure vessels.
