Grounding, Bonding and Lightning Protection

Overview

Grounding, bonding and lightning protection are fundamental to electrical safety, equipment protection and the prevention of fires and explosions in oil, gas and petrochemical facilities. Poor earthing can leave equipment enclosures at dangerous voltages during faults, prevent protective devices from operating, damage sensitive electronics and allow static charges to ignite flammable vapours. Storage tanks, process structures, pipelines and buildings in exposed locations are also vulnerable to lightning strikes, which can cause fires, equipment damage and loss of control systems if protection is inadequate or poorly maintained.

This course provides a practical understanding of grounding, bonding and lightning protection for industrial facilities. Participants learn the purposes of system and equipment earthing, earthing system types, earth electrodes and soil resistivity, and the design of earthing networks for substations and process plants. The course covers equipment bonding, static electricity control for tanks, loading operations and piping, instrument and signal earthing, and the earthing of hazardous area equipment. It also explains lightning phenomena and risk assessment, lightning protection systems for buildings, tanks and structures, surge protection devices, earth resistance and continuity testing, inspection, maintenance and investigation of earthing problems.

Objectives

• Explain the purposes of system earthing, equipment earthing and bonding
• Compare earthing system types and their effect on fault currents and safety
• Design earthing networks using electrodes and soil resistivity data
• Control static electricity in tanks, loading operations and piping
• Apply instrument earthing and hazardous area earthing requirements
• Assess lightning risk and specify lightning and surge protection systems
• Test, inspect and maintain earthing and lightning protection systems

Who should attend

Training methodology

The course combines explanation of earthing principles with real earthing layouts, single-line diagrams, test reports and photographs of installations. Participants calculate electrode resistance from soil data, review substation and plant earthing designs, plan bonding arrangements for tanks and loading racks, carry out lightning risk assessments and interpret earth resistance and continuity test results. Demonstrations of earth testers are included where available. Case studies of static ignition fires, lightning strikes on tanks and equipment damage due to poor earthing are analysed in groups. Each day ends with a short quiz and discussion.
