Decommissioning

From end-to-end solutions to discrete tool hires, we solve your decommissioning challenges safely and cost-effectively.

Building on our track record of reliable cutting and tooling services, we offer turnkey solutions that meet the demands of the industry’s largest work scopes. At the end of a field’s life, we efficiently remove assets of all types—manifolds, pipelines, wells, umbilicals, and topside set-ups.

Flexible Project Execution

Our technical expertise and ability to react to unplanned events during project execution make us the industry leader in integrated decommissioning services. Our solutions reduce mobilization costs, which reduces health, safety, and environmental (HSE) risk throughout a decommissioning operation.
Because we are experienced in managing projects from top to bottom, and even across multiple assets, we ensure compliance with varied and stringent government regulations.

Customized Plug and Abandonment Solutions

We collaborate with you to meet your specific plug and abandonment (P&A) requirements, using scalable combinations of Oceaneering technologies and services. We combine competencies from across our organization, and around the world, to best serve your operation.

Our integrated decommissioning solutions can incorporate one or more of the following services.

Cutting

Our cutting tools include solutions for shallow and deepwater internal and external abrasive waterjet cutting, plus internal cutting tools for piles and caissons. Additional mechanical cutting functionality is provided by an extensive suite of saws and sectioning tools.
