The main quality assessment techniques provided by BBL are:
• Inspection during manufacture of materials and equipment
• Inspection of civil constructions and electromechanical assembly
• Witnessing of the final manufacturing, type, reduced model testing and equipment
  commissioning
• Conducting or witnessing nondestructive testing
• Inspecting equipment in use or in maintenance
• Auditing manufacturers’ quality system, process or product
• Subcontractors qualification or auditing

Below is a list of electromechanical equipment normally submitted to quality assessment, although other components may be included:
