Structure removal

Ashtead Technology have an extensive array of packaged solutions covering a range of structure removal applications.

Ashtead Technology has in-depth experience and knowledge in providing solutions to support structure, flowline and infrastructure removal and monitoring operations in real-time.

Removing structures and flowlines safely can require special application-specific tools, which can be either ROV or diver deployed. These tools often require remote control, varying levels of automation and monitoring to execute their functions. This requires careful engineering and implementation.

We can provide complete tooling and associated control and monitoring solutions, including independent real time structural monitoring. Our team can support many decommissioning tooling control system and structural monitoring needs, providing full control and visibility throughout critical phases of structure removal operations.

Discover how Ashtead Technology incorporates market-leading technologies and innovative life of field services to help clients deliver complex projects.

We offer a wide range of services to deliver application specific tooling, control and monitoring solutions for all stages of the decommissioning process. Along with special tools, we can provide control and automation functionality and monitoring sensor systems to allow for full control throughout the operation.

Structures that have deteriorated over time may require custom- engineered solutions to remove marine growth and safely remove and recover subsea and topside structures and components. Where complex removal stages are required, the process can be accelerated or simplified through the use of automation, and where required remote verification processes can be used to confirm successful completion.

With our in-house engineering capabilities, we can support many equipment and tooling needs to develop a solution that delivers benefit through improved safety, minimal technical risk and reduced vessel time in executing work scopes.

Ashtead Technology are leaders in subsea structural monitoring solutions for the deployment and recovery of heavy structures such as manifolds, templates and jackets.

During the removal of heavy structures, suction piles and other heavy lifts, it may be necessary to monitor the extraction process, particularly if the structure is suction or pin-piled. Monitoring technology can be used to ensure the structural disengagement and recovery to surface isn’t causing undue stress. This reduces the risk of structural failure.

With our in-house structural monitoring expertise, data management and software visualisation capabilities we work closely with our clients to engineer robust solutions that allow full visibility and easy to understand visualisation of what is happening to subsea structures during critical phases of extraction and recovery, reducing technical risk and costs.
