We leverage local content to help us provide a strong platform for delivering commercial benefits. This includes optimising supply chains so that we can deliver excellence wherever we operate. Being vessel-independent further minimises costs and package deck footprint.

Oil and gas conductor casings that have been cut and recovered during decommissioning operations

We understand that most oil and gas assets were not designed with decommissioning in mind. With regulatory challenges varying by location costs need to be minimised. We strive to optimise and reduce the time, cost, and risk of decommissioning operations through our rigless approach to well abandonments.

Solving your most pressing challenges

How can we work with more and more stringent regional regulations?

Acteon solution: 

Through Acteon’s independently operated brand 2H, we provide expert guidance on permitting to simplify and expedite the regulatory process. We have a strong track record of helping customers secure project permits in the most stringent regulatory environments, both onshore and offshore. Working with various stakeholders, from regulatory authorities to public interest groups, we help clients navigate and expedite complex regulatory processes. We also ensure that all operations including piling meet regional legislation. 

Proof points: 

  • 2H California is regularly commissioned by the California State Lands Commission to perform well re-abandonments. 
  • MENCK developed a solution to address the challenges of environmental noise by designing ‘primary’ noise mitigation systems. These systems are integrated into the hammer and change the force character of the hammer to reduce the noise before it is transferred into the water. 
  • We use digital solutions allowing the engineer at home or remote location to plan offshore works, undergo site familiarisation, inspection, and maintenance identification all without having to go offshore. 
  • We have an extensive network of over 100 locations in more than 20 countries, allowing us to leverage local expertise at any time.

We need a contractor that has experience in deep and ultra-deep water.

Acteon solution:
As far as installing platforms and exploration-production vessels in deep and ultra-deep water, Acteon was one of the precursors and has established several industry records in waters up to 9,400ft. (2,890m). To provide seamless project management, efficient engineering and offshore delivery services, Acteon develops project-specific installation aids, methods and procedures.

Proof points: 

  • Acteon has remained at the forefront of construction and foundation innovation, as the only company worldwide to offer a full conductor installation service in deepwater – currently being used for some of the largest ultra-deepwater projects in the world. We install conductors by driving them to the desired penetration with a MENCK-built deepwater subsea hydraulic hammer spread. The spread allows these services to be provided in water depths up to 7,300 ft. with +/- 3-inch elevation accuracy. 
  • Deep water riser and flowline integrity management programmes from Acteon can also maximise production uptime.  
  • We completed the installation of the seven anchor mooring piles for a CALM Buoy, drilling from a DSCV in water depths over 270m. 
  • We provided positioning technology on a world-class ultra-deep water field development project in Africa, with depths exceeding 2,000m.
