Oil & Gas Commissioning and Decommissioning Support Services

Megarme Group delivers integrated commissioning and decommissioning support services for offshore and onshore oil and gas assets, combining safe access, technical expertise and disciplined project execution.
Our teams support pre-commissioning, commissioning, shutdown, transition, decommissioning and close-out activities where safety, planning, technical competence and efficient delivery are critical.

  • Access. Support. Execute.

Commissioning and decommissioning works form key stages within the asset lifecycle. These activities often involve complex access requirements, multiple technical disciplines, strict safety controls and time-sensitive project schedules.

Megarme Group helps clients manage these scopes safely and efficiently by combining rope access, inspection, mechanical support, fabric maintenance, tank cleaning, safety supervision and project coordination within one integrated delivery model.

This approach reduces reliance on multiple contractors, improves communication, supports stronger site control and allows clients to complete several related activities within one controlled mobilisation.

  • Complex Access Support

Commissioning and decommissioning activities are often located in areas where traditional access is difficult, time-consuming or disruptive. This can include elevated structures, restricted areas, congested process equipment, pipe racks, vessels, tanks, marine structures and offshore installations. Megarme Group’s rope access capability allows trained technicians and specialists to reach these locations safely and efficiently, reducing the need for scaffolding or large temporary access systems. This helps clients complete inspection, preparation, removal, reinstatement and maintenance tasks more efficiently, particularly during shutdowns, campaigns, restricted work windows or time-sensitive project phases.

  • Complex Access Support

Megarme Group’s commissioning and decommissioning support can be combined with NDT, fabric maintenance, preservation works, mechanical support, tank cleaning, inspection support and rope access supervision as part of a single integrated delivery model.

 

This helps reduce personnel on board, improve planning, minimise contractor interfaces and maintain better control over safety, quality and execution.

 

By using multi-disciplined teams, clients can complete multiple work scopes through one coordinated service provider, improving efficiency while reducing complexity during critical project stages.
