ESC conducted the preparation of Safety Case, Quantitative Risk Assessment (QRA), Occupied Building Risk Assessment OBRA), and Pollution Control Study (PCS) as part of the client’s legal requirements for Major Hazard Installation (MHI) in Singapore.
About the Project
ESC was commissioned by a multinational energy corporation and its facility in Singapore to conduct various permitting studies of one of the client’s expansion projects together with their base plant facilities to enhance its supply and production capabilities.
ESC is registered with the Singapore National Environment Agency (NEA) as a consultant authorized to undertake Quantitative Risk Analysis, Pollution Control Studies, Site Assessments, and the remediation of contaminated sites.
Our Approach
ESC conducted a series of permitting studies for the client in order to obtain in-principle approval for their expansion plans.
Initially, ESC conducted the Quantitative Risk Assessment (QRA) and Pollution Control Study (PCS) of one of the client’s expansion projects together with their base plant facilities. ESC was retained again once the client had further expansion plans, and ESC re-conducted the QRA in order to obtain in-principle approval from the Singapore authorities under the new QRA guidelines. Currently, ESC is retained to assist the clients’ team to fulfil the new MHI requirements.
In addition, ESC also assisted the clients’ Safety Case team with the development of the Safety Case including:
- identification of Major Accident Hazards (MAHs)
- Major Accident Scenario (MASs)
- Safety Critical Events (SCEs)
- Occupied Building Risk Assessment
- Human Factors
- ALARP (As Low As Reasonable Practicable) Demonstration
- Emergency Response Plan (ERP)
Outcome
In line with National Environment Agency’s (NEA) criteria, ESC recommended mitigating measures for the proposed expansion projects in order to ensure that the risk posed to surrounding areas is reduced to ALARP level based on industry best practices. ESC has successfully obtained planning and approval for the client for both QRA and PCS and was retained to assist with all Permitting studies during the buildout of the facility.
As one of the NEA-approved consultants for QRA, ESC’s process safety management experts have made valuable contributions towards the safe operations of the facilities processes, whilst providing innovations considerations to minimize potential impacts to the facility and its surroundings.
