SA10 Asset Integrity

What is the definition of asset integrity?

• The ability of an item to hold together under a load without breaking or deforming excessively

• The application of technical, operational, and organizational solutions to reduce risk of uncontrolled release of formation fluids

• The management of major accidents with energy release

• The ability of an asset to perform its function effectively and efficiently

Answer explanation

Asset Integrity: Ability of an asset to perform its function effectively and efficiently.

What is Structural Integrity?

• Ability of an item to hold together under a load, including its own weight, without breaking or deforming excessively.

• Ability of an item to hold together under a load, including its own weight, by breaking or deforming excessively.

• Ability of an item to hold together its own weight only.

• Ability of an item to deform under its own weight only.

Answer explanation

Structural integrity is the ability of an item - either a structural component or a structure consisting of many components to hold together under a load, including its own weight, without breaking or deforming excessively.

What is the definition of well integrity?

• The management of major accidents with energy release throughout the life cycle of a well

• Application of technical, operational and organisational solutions to reduce risk of uncontrolled release of formation fluids throughout the life cycle of a well

• The ability of an item to hold together under a load without breaking or deforming excessively throughout the life cycle of a well

• The hole dug into the earth to bring oil or other hydrocarbons to the surface throughout the life cycle of a well

Answer explanation

Application of technical, operational and organisational solutions to reduce risk of uncontrolled release of formation fluids throughout the life cycle of a well

What is Safety Critical Elements?

• The essential components which maximise the effects of a major accident.

• The essential components which prevent or limit the effects of a major accident.

• The essential components which prevent or limit the effects everyday operation.

• The essential components which maximise the effects everyday operation.

Answer explanation

Safety Critical Elements (SCE) are the essential components which prevent or limit the effects of a major accident.

• Fire and gas detection system

• Fire Fighting Equipment

Answer explanation

• - Pressure Relief Valve

• - Emergency Shutdown system

• - Fire and gas detection system

• - Fire Fighting Equipment

What is the purpose of a pressure relief valve?

• To control or limit the pressure in a system to prevent process upsets or equipment failure

• To minimise the consequences of an emergency situation such as a failure

• To give the earliest possible warning of the outbreak of fire through detection

• To extinguish fires using portable fire pumps and fire hose reels

Answer explanation

It is used to control or limit the pressure in a system; pressure might otherwise build up and create a process upset, instrument or equipment failure, or fire.

What is the main purpose of a bow-tie diagram?

• To illustrate the model of barriers for safety critical elements

• To safeguard employees from the unexpected energization or startup of machinery and equipment

• To identify and assess risk in order to prevent harm to people, damage to the asset, or harm to the environment

• To improve the risk assessment process by identifying weaknesses in the system

Answer explanation

To improve the risk assessment process by identifying weaknesses in the system.
