Reducing vessel time and interface complexity

We combine multiple capabilities into a single interface - optimising deck space, personnel and vessel time, and simplifying logistics throughout execution.

Rig positioning

Precision rig positioning for mobile offshore units

Acteon delivers fast, accurate drilling rig positioning services to support safe mobilisation and demobilisation of mobile offshore drilling units (MODUs) and drilling barges. With extensive global experience, our teams use ultra short baseline acoustic positioning systems (USBL) and other technologies to confirm target location and stability during offshore rig moves. 

Our real time approach reduces offshore standby time, supports operational safety and ensures location precision in all conditions. 

Floating energy production facility positioning

Positioning and hook-up for floating production systems

We support long-term subsea infrastructure stability and monitor movement over time to validate station-keeping and performance. 

From floating production storage and offloading (FPSO) units to floating liquefied natural gas (FLNG) units, Acteon provides offshore positioning support and heading control during hook-up and mooring operations. Our teams enable smooth, secure connections in tight windows, helping operators reduce time to first production.

Offshore construction for FPSOs – delivering margin, speed and certainty

Offshore construction is the work that brings an offshore energy project to life. It’s a chain of interdependent phases: positioning, construction support, and foundation or mooring system installation. Each stage brings its own challenges. While design work may be finalised early, offshore success depends on how well those plans adapt to real-world conditions.
