Efficient and effective subsea well intervention and decommissioning services

Subsea intervention can be challenging—the operating environment, well conditions, and economic viability all pose a risk to successful performance. We meet the challenges by providing reliable, innovative, and proven subsea well access systems that enable fit-for-purpose subsea intervention and decommissioning services, including

  • riser-based services
  • riserless services
  • open-water hydraulic intervention
  • riserless open-water abandonment.

By delivering unparalleled expertise and technology to your job, we maximize the potential for achieving successful intervention objectives, whether enhancing well or reservoir diagnostics or being prepared for contingency solutions.

Complete intervention package

Subsea asset interventions require a variety of equipment—a well access system is simply a precursor to a complete solution. We provide all required interfaces, tooling, and control systems through one integrated service incorporating the components for your situation, such as

  • remotely operated vehicles
  • intervention and workover control systems
  • tree and production system tooling and adapters.

 


Based on our decades of experience and leading technology development, we bring innovative ways to maximize operational efficiency, from implementation of digital tools for monitoring to integrated deployment equipment and methods.
