Major Accident Events & Emergency Response on FPSO to prevent disasters like Piper Alpha (Preparedness, Response, Recovery and Mitigation)
About FPSO Floating Production, Storage and Offloading (FPSO) unit is a huge dominant floating production system for offshore oil and gas fields. FPSOs are effective development solutions for both deep-water and ultradeep-water fields and their main advantage is the agility and ability to process and store the hydrocarbons.
MAE’s Fire within Accommodation Space Fire and explosion in Engine Room Fire and explosion in E-House Ship collision Helicopter crash on Helideck Loss of topside structural integrity Dropped object/ uncontrolled swing load Loss of FPSO stability Occupational accidents Personnel transfer failure (vessel to vessel) Dropped Fast Rescue Craft Loss of containment from Production Separation/ Stabilization System Loss of containment from Gas Compression System Loss of containment from Gas Dehydration System Loss of containment from Fuel Gas System Loss of containment from Flare System Loss of containment from Chemical Injection & Helifuel System Loss of containment from Hydrocarbon Release from Cargo Handling System Loss of containment from Turret System Loss of containment from Riser and Subsea Pipeline Fire and explosion from Cargo Tanks
MAE’s Loss of containment (un-ignited) - Environmental Oil Pollution Loss of containment (ignited) - Fire & Explosion Fatality(ies) Helicopter crash Structural failure / loss of buoyancy Extreme weather / natural disasters Piracy / bomb threat / terrorist activity / Cyber attack
MAE’s & RISKS Potentially hazardous processes and operations are identified during the Project Phase, in order to, as far as possible; eliminate these hazards during the engineering process. Where residual risk remains, “barriers” are provided for the prevention, detection, mitigation and control of Major Accident Events (MAEs). What are these barriers
Why barriers? INCIDENT (e.g. gas release) THREAT (e.g. corrosion) CONSEQUENCE (e.g. fire) Barriers prevent an incident occurring or stop it getting worse
What is a barrier?Barriers can be categorised as plant, process or people. plant, process, people plant, process, people INCIDENT (e.g. gas release) CONSEQUENCE (e.g. fire) THREAT (e.g. corrosion) PREVENTATIVE BARRIERS MITAGATIVE BARRIERS
Types of Barriers Barriers can be grouped into 3 categories: plant, process and people. Plant Safety equipment and systems designed into our plant Process People The way we work The right people, with the right behaviours, who are trained and competent for the role
Types of Barriers Safety equipment and systems designed into our plant Plant Think of examples of plant barriers

Safety & Environmental Critical Elements (SECEs) A SECE is a barrier which is a piece of safety equipment or a system which prevents a Major Accident happening or stops one getting worse. • TR Door • Deck Drain • Helideck • Deluge system • F&G detector • Emergency lights • HVAC system • PA systems • Escape routes • Xmas tree Why do you think these are regarded as Safety Critical?

Defeating Barriers Sometimes barriers are ‘defeated’ Over-ridden (purposefully or accidentally) Broken Degraded Impaired Missing Not fit for purpose / badly designed Obstructed
Emergency Preparedness The Facility’s emergency preparedness arrangements provide and establish: • An organizational structure capable of handling major incident events effectively; • Emergency Response Plan (ERP) in respect of the identified MIEs • Arrangements with respect to emergency training & drills; • A means for partial or full evacuation; and • A communication structure for the provision of external assistance, support and reporting.

We have to move from tradition of Response to a culture of prevention, a culture of resilience.
