How it works

What you get

The end-of-life cost
Decommissioning estimated with the same discipline as construction.
By sector
Separate models for oil & gas onshore and offshore, process plants, renewables, mining and nuclear.
Activities that drive the cost
Removal, demolition, waste handling and site restoration as the cost blocks.
Part of the life-cycle cost
ABEX completes CAPEX and OPEX in the estimate.
