Major Accident HazardMajor Accident Hazard
An occurrence resulting from uncontrolled developments in the course of the operation of any onshore establishment or pipeline or offshore installation, and leading to serious danger to human health or the environment, immediate or delayed, inside or outside the onshore establishment or offshore installation, and involving one or more dangerous substances.
This includes in particular a major: Emission Fire Explosion.

• Lack of adequate warning
Asphyxiation/ poisoning
• Gas leak in confined space
• Leak of toxic chemicals
• Discharge of fire extinguishing agent in confined space
• Smoke from fire
Burns shock
• Hot surfaces• Flare radiation• Burning fluids
Inability to escape
• Blocked escape route• Insufficient lighting
• Inappropriate survival capsule design or location
• Lack of fire barriers• Lack of adequate warning• Lack of communications• Lack of visibility• Inadequate training
Injury
* Sources which can be anticipated by sensing charges in process conditions
Fire Explosion
Safety Critical SystemSafety Critical System
A Safety Critical System (SCS) is any part of an establishment or installation that has a significant role with the:
Control of major process hazards Limitation and recovery from containment loss Limitation and recovery from fire and explosion Escape and refuge Evacuation and rescue.

Following scenarios are the most common undesirable events which can lead to an Emission and/or Fire & Explosion Major Accident in a plant which processes the flammable and/or toxic materials:
According API 14C at least two levels of protection independent and diverse shall be provided wherever these hazards are credible.

A Typical 3D model of an oil & gas plant consists of 1-3 million object.Considering the life cycle requirements, activities and tasks for each object billions of data, information and knowledge should be managed. Without a robust and reliable database management configuration management remain a very good method but impractical.

ADEPP Monitor is used to improve requirement management:
• Convert the requirements from the different bulk document to short, traceable and auditable Performance Standards to express the requirements in terms of:
• Functionality• Reliability / availability• Survivability• Dependency / Interaction
• Link the required Verification Scheme to each Performance Standard.
• Plan the required Activities and assign the Tasks to each performance standard and relative verification scheme.
• Provide the Online Action Tracking system to be used efficiently by people who are located in physically remote offices/sites.

ADEPP Monitor is easy to be customised, used and modified for any application because like “Lego” it consists of the ready made blocks rather than a rigid and centralised database like an “Intelligence Cube”.
