IKM are delighted to have been appointed to provide further multi-disciplinary services to one of Europe’s leading independent crude oil refiners, for the construction of two new diesel tanks at an existing fuel storage terminal in north-west England. The additional works will include the design of the civil/structural items associated with the new tank infrastructure, drainage and access.
IKM have initially supported our client through the project planning process by:
- Submitting successful planning applications;
- Undertaking a fully costed options appraisal to identify a suitable bund configuration, bund lining and drainage system;
- Undertaking a geo-environmental desk study to inform the site investigation requirements;
- Undertaking a topographical survey.
We then delivered the detailed design of the secondary containment structures which included the following:
- Intrusive geo-environmental site investigation to determine ground conditions, anticipated settlement and waste classification;
- Design of reinforced concrete raft foundations with an integral leak detection system;
- Design of the closed internal bund drainage system.
- Design of a reinforced concrete secondary containment system in accordance with industry good practice guidance (CIRIA 736 & PSLG) to satisfy the requirements of the COMAH regulations;
As part of this work, IKM have identified that the site of the new build tanks is constrained by existing adjacent plant and the site boundary. IKM have carried out a risk assessment to identify significant hazards and potential mitigation measures.
This has led to us being appointed to progress a study to determine the requirement for additional tertiary containment outside the new bund. This will include computational fluid dynamic analysis to calculate overtopping volumes for a number of catastrophic tank failure scenarios. This will determine overland flow models, to allow potential improvements to be detailed ensuring the environmental and safety integrity of future site operations.
