Whether accredited to API or ECITB, there are a number of key elements common to both:

• Health and safety in relation to the offshore industry and COMAH sites
• Theory of components within the bolted flange connection
• Preparation of bolted flanged connections prior to assembly
• Assembly of bolted flanged connections
• Tightening methods
• Tightening of bolts using hydraulic tensioning equipment
• Theory, practical and demonstration of the correct and safe practice of assembly and tightening
• Inspection process for components
• Failure mechanisms/root cause
• Audit and record all information

These elements give the candidate a basic underpinning knowledge of the principles and practices associated with assembly and controlled bolt tightening of a bolted flanged connection.
