CASE STUDY

Project Specifications


Brief

IES, in conjunction with one of Australia’s leading environmental consultants, was awarded the Underground Petroleum Storage Systems (UPSS) exhumation portfolio of works for a major petroleum refiner/retailer. The project consisted of coordination and safe execution of the decommissioning and exhumation of 32 tanks, varying in size from 5kL – 70kL across Victoria, New South Wales, Tasmania, South Australia and Western Australia. Jointly, the consultant and IES drew upon several of the companies petrochemical specialist, and environmental assessment teams to deliver the nominated sites simultaneously without a reportable injury or significant incident.

The Client tasked both specialised business divisions to deliver the portfolio of sites on a National level covering sites Australia wide, “the brief” to safely decommission redundant retail fuel storage systems and remediate sites in country Victoria, Tasmania, New South Wales and Western Australia simultaneously. Specialised IES supervisors and teams, supported by site based environmental consulting personnel completed both the Victorian and interstate sites incident free, within the scheduled timeframe and delivered the sites within the agreed budget.

Execution

The overall program incorporated UPSS decommissioning and onsite remedial works, with the first stage of delivery including demolition and remedial activities at six redundant retail centres. Our scope primarily involved the decommissioning and exhumation of existing UPSS and fuel related infrastructure from each site.
Our approach for this program of works, as with most, was designed to minimise remediation requirements, maximising site time through technical innovations, team work, pre-planning, and local council and stakeholder engagement.

In addition, during the course of exploratory excavations, our teams discovered three additional underground storage tanks onsite, which were identified as containing cement stabilised sand and previously decommissioned in earlier works. The complications associated with the discovered orphaned tanks included potential explosive environments, without the ability to apply conventional de-gassing methods to enable onsite destruction to accommodate for weight/handling and cost efficiencies. This was addressed by implementing our cold cutting hydraulic shear technique.

The approved (minimal ignition risk methodology) involved safely processing by cold cutting the insitu UPSS with the excavator fitted with a specialised shearing attachment. Although this unforseen scope had the real potential to impact both the works program timing and budget, the flexibility of IES in cooperation with the environmental consultant allowed the site personal to deliver the project in a safe, timely manner maintaining the project’s prime objectives.

Outcome

ES has a thorough understanding of the petroleum industry and project needs, including the need to optimise return on land following decommissioning and remediation. We also have an excellent understanding of physical environment, optimising on local industry contacts and resources for engineered fill and other resources based on our previous experience. This has enabled us to develop an approach that maximises commercial returns and minimises cost uncertainties and risks.

Our comprehensive project understanding, front-end and ongoing strategic planning, coupled with clearly-defined and well understood project priorities, tasks and responsibilities, have been key to our success in delivering major and complex projects for our clients. We have contributed in the delivery of a large number of Australian site closures for our petroleum clients over the past few years on or ahead of schedule and within budgets. This project presented the unique challenges of multiple sites separated across a large geographic area that required expedited successful completion within 62 working days at a fixed cost delivering.
