Oil and Gas

Claxton Drilling Templates


Our products and services provide vital support to oil and gas customers as their focus shifts towards gas production, deeper-water operations, mature field management, and decommissioning.

Acteon has supported the oil and gas industry for decades by delivering cost efficiencies and project timeline savings on large and complex projects in all water depths. Our services include pre-development and front-end-engineering, development drilling services, foundations, moorings, production asset installation, asset integrity monitoring and management, field life extension and decommissioning. This breadth of skills enables us to provide customers with all-in-one project support and reduce project footprint while minimising environmental impact.


As oil and gas fields around the world mature, operators are faced with the decommissioning of their offshore assets. At Acteon, we understand that most of these assets were not designed with decommissioning in mind, that regulatory challenges vary by location, and that 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. Combining our innovative equipment, including the patented SABRE™ and SWAT™ tools, bespoke expert engineering and skilled personnel also allows us to focus on efficiencies while performing quality work.

We have an extensive track record of efficiently and safely decommissioning all types of floating facilities, from risers to calm buoys to entire platforms.

Using our well abandonment services, remedial experience, and floating facilities removal expertise, we also help operators restore the subsea marine environment.


Acteon provides a single interface for the seamless delivery of drilling support services, from project management and surveying to mooring and riser system engineering, supply, installation. This minimises project time, cost and drilling risk.

We simplify rig moving and station-keeping by providing a service that includes site survey, on-board towmasters and mooring and riser design through to procurement and offshore installation.

We provide riser analysis, subsea well equipment, riser connections, conductor centralizers and tensioning systems, and protect the riser through high-quality solutions and expert operational planning.

Being independent of vessel providers allows to us source the most efficient vessel for the task, which minimises costs and package deck footprint.


Acteon’s customisable and integrated installation and positioning solutions reduce the risk of cost overruns, expedite floating facility installation and increase lifetime value. Our single interface prevents simultaneous operations and avoids schedule conflicts between contractors.

Cost efficiencies are maximised by life-of-field management, which covers geotechnical services, structural design, regulatory approval, procurement, fabrication, installation and decommissioning. Installation costs are further reduced by using the most efficient vessel of opportunity.

We also offer data gathering and monitoring systems to facilitate and mitigate risks and complications of future maintenance and decommissioning work.

We have worked on some of the world’s largest and most complex oil and gas developments. Examples are shown in the table.
