Decommissioning

The decommissioning of redundant infrastructure is high risk and demands specialist skills and experience to ensure zero harm to workers, as well as the surrounding environment and neighbouring communities. CMA works closely with our clients to effectively ‘de-risk’ end of asset lifecycle projects and to delivery certainty of outcomes.

Systems Identification, Mapping & Wind-Down

CMA provides end-to-end decommissioning planning for complex industrial facilities including power stations, refineries, and mineral processing plants. Our teams systematically identify and map process systems, developing strategic wind-down sequences that prioritise safe isolations, breaking containment, and inventory drain works. Integrated hazardous materials investigations inform our abolishment strategies, enabling methodical service cut-back while maintaining only those critical systems essential for closure operations.

Consulting & Advisory

CMA provides specialist consulting and advisory services for industrial closure and decommissioning projects. Our experienced team delivers closure planning studies, cost modelling, risk assessments, and strategic advisory support to asset owners navigating end-of-life decisions. We help clients optimise closure outcomes, manage stakeholder expectations, and develop execution-ready strategies that reduce uncertainty and total project cost.

Industrial Cleaning & Hazmat Material Management

CMA delivers industrial cleaning and hazardous materials management services for complex decommissioning and closure projects. Our capabilities include vessel and tank cleaning, hydro-blasting, chemical decontamination, and the systematic identification, removal, and disposal of hazardous substances. We maintain full chain-of-custody for all waste streams, ensuring compliant disposal through licensed facilities and approved pathways.

Total Systems Isolation

CMA provides comprehensive isolation and abolishment services for electrical, mechanical, and process systems across industrial facilities. Our methodical approach ensures safe de-energisation, positive isolation, and systematic service termination while maintaining critical infrastructure required for ongoing closure activities. Detailed isolation registers and abolishment tracking deliver full auditability and operational certainty throughout decommissioning works.

Asset Recovery & Salvage

CMA maximises value recovery for clients through strategic asset salvage and resale programmes. Our teams identify, assess, and recover reusable equipment, materials, and commodities from decommissioning projects, diverting valuable resources from landfill while generating returns that offset closure costs. We manage the full salvage cycle from identification through to sale or responsible recycling.

Integrated Decommissioning Oversight

CMA’s early works decommissioning capabilities are integrated into the out teams of our clients (asset owners) to bridge the gap between operational shutdown and asset closure using the clients’ historical operational team and operators. Our teams oversee make-safe programmes, soft stripping, process system cleaning to prepare complex facilities for safe handover. This systematically de-risks legacy infrastructure and establishes the optimal conditions for subsequent demolition activities.
