1. INTRODUCTION
Chevron Nigeria Limited plans to engage the services of qualified contractors to provide consequence modelling and quantitative risk assessment (QRA), which include an assessment of Escape and Evacuation (EERA) and the emergency system (ESSA) for all its operational areas on call-out basis.
2. AREA OF COVERAGE

3. SCOPE OF WORK
The scope of work for the services includes but not limited to the following:
a. Frequency assessment
The Frequency Assessment includes the following stages:
- Parts count-Parts counts will be based on the CORSA pre-defined assemblies, so the vendor will only need to define the isolatable section. Release points are also pre-defined in CORSA according to the equipment assemblies in use.
- Initiating event frequencies Release frequencies from the major equipment assemblies are calculated by CORSA for four-hole sizes between 3mm and 100m.
- Event tree analysis-CORSA pre-defined event trees will be used to quantify the risk.
- Escalation analysis-Customization of the rule-sets to identify the potential for event escalation, where this could provide incremental risk to humans, the designated Temporary Refuge, or the facility.
b. Escape, evacuation and Rescue Analysis
This task will evaluate the escape, evacuation, and rescue procedures and systems for the facility and demonstrate whether personnel can reach a safe haven in the event of major accident scenario, and subsequently evacuate the facility if required. The analysis shall verify that the protection offered by the Temporary Refuge (TR) ensures it provides sufficient time to complete a safe escape and evacuation from the facility. The survivability of the TR and impairment frequency and the efficacy of the various escape routes will be determined using the results from the previous tasks including the detailed consequence modeling. CORSA includes this ability in its coding.
c. Process safety assessment for occupied building
Process Safety Assessment for Occupied building This task will model the worst credible consequences to evaluate capability of each building potentially exposed to process event to provide occupant protection from risk associated with potential external fires, explosion, smoke, flammable gas, and toxic material release. The term building applies to permanent and portable buildings consistent with the definition of API 752, API 753, and API 756. These will include buildings that may become occupied during emergency. e.g., Temporary Refuge or remain occupied during emergency e.g. control room. The potential consequences should include;
- Exposure to flammable vapor clouds
- Exposure toxic vapor clouds
- Exposure to explosion overpressure
- Exposure to thermal radiation from fire
- Exposure to smoke from fire
d. Risk quantification
The following risk measures will be required to satisfy the requirements of the Chevron Risk Management Procedure (Riskman2) as a minimum
- Location Specific Individual Risk
- Individual risk of fatality to personnel, accounting for distribution across the facility and occupancy for different worker groups
- Societal risk in the form of F-N curves, corresponding to the frequency of having an accident leading to ‘N’ or more fatalities, up to the total number of people (including daytime and nighttime shifts and allowance for periods of enhanced occupancy such as drilling activities)
