As the one of the leading EHS & Risk consultancies in Southeast Asian region, EnviroSolutions & Consulting (ESC) has strived to continuously develop its team and the quality of its professional services to its clients. As an important scope of its Industrial Permitting Advisory services, ESC has managed and delivered more than 30 Quantitative Risk Assessment (QRA) projects in Singapore over the past 5 years and gained significant recognition amongst local clients and government agencies.Since December 2012, ESC has been working closely with SAVE, which is part of Oranjewoud Netherlands, a member of the Antea Group, beginning with the Jurong Rock Cavern (JRC) QRA project. Coming from a strong background in industrial process risk assessment with decades of technical and practical experience in the Netherlands, the SAVE team provided valuable expertise on this project. The JRC project, with a capital investment of $950 million, is the first underground hydrocarbon storage facility in Southeast Asia. Located approximately 130m beneath the seabed in the Jurong Island region of Singapore, the massive rock cavern will store over 2 million cubic meters of liquid hydrocarbons and save up to 60 hectares of above-ground land area for the land-scarce city state.
However, due to the unprecedented nature of this project in Singapore, the risk of underground oil explosion causing loss of containment, and subsequent above-ground damage could not be adequately assessed using standard QRA methodologies and models. Such standard models are designed based on empirical data and are built to cover a wide range of accident cases and hazardous installations. Conservative analysis using generic QRA models would produce consequence results many times larger than in reality, leading to mitigation measures or safety systems which are unnecessarily overdesigned
To overcome this challenge, the ESC-SAVE team employed advanced Computational Fluid Dynamics (CFD) modelling to simulate the underground explosion impacts, which is highly uncommon for QRAs in Singapore. In CFD modeling, the 3D geometric model of the structure (in this case, the rock cavern) is produced and utilised within the software. This additional input improves the robustness of the analysis and increases confidence in the results. The combined effort between ESC and SAVE was highly successful in introducing CFD modelling for QRA projects to the Singapore regulating authorities and received much positive feedback from these authorities
Building upon the JRC QRA project, ESC continued to engage SAVE to provide technical training for ESC's QRA team through a comprehensive 3-months' program. Together, the team collaborated on two ongoing QRAs for petrochemical process plants on Jurong Island, namely Evonik Oil Additives and Chevron Oronite. The training by SAVE has enhanced the ESC team's technical capacity to meet the growing scale and demand for complexity for QRAs in Singapore. At the same time, ESC and SAVE have also launched a joint investment to explore new business development opportunities in both onshore and offshore risk assessment, harnessing ESC's regional network and understanding of regional regulatory developments to introduce SAVE's rich European technical expertise to new markets in the Asia-Pacific region.
