Layer of Protection Analysis Study (LOPA)

LOPA is developed in response to a requirement within the process industry to be able to assess the adequacy of the layers of protection provided for an activity.
Examples of layers of protection used in the LOPA study are:

• Process
• Process Design
• Alarm, Operator Action
• Automatic Action (Safety Instrumented System, Emergency Shutdown, Automatic Fire Suppression)
• Active / Passive protection in place
• Plant Emergency Response

At Occupli Consultancy, we will estimate and evaluate the risk by defining all the existing layers of protection and also giving recommendations of basis of safety to be implemented.
