Escape, Evacuation, and Rescue Analysis (EERA)

The overall scope for the Escape, Evacuation, and Rescue Analysis (EERA) is to qualitatively examine and evaluate the effectiveness of EER facilities available on an offshore installation from major accident events which could occur during normal operations (operational phase).

The EERA comprises of the following:

• Set EER goals and objectives for the facilities;
• Identify escape, evacuation and rescue (EER) facilities provided to enable personnel to escape from the immediate effects of accident events, and, if necessary, evacuate the installation and reach an ultimate place of safety;
• Identify accident events (from the results of FERA consequence modelling and ship collision study) that would necessitate the use of the EER facilities;
• Determine the availability of escape routes following a major accident event, and the potential for impairment of EER facilities, when they are required;
• Determine the minimum endurance time required of the EER facilities based on estimating time of muster and evacuation and evaluate against the basis of design; and
• Assess whether the defined EER goals and objectives are met, and if not, actions required to meet the goals.

It is recommended that EER issues during simultaneous operations (SIMOPS) be addressed separately in a dedicated SIMOPS Study.
