Petrobras awards Acteon 3-year stack-up mooring system services

Intermoor, Acteon’s Moorings and Anchors business line is proud to announce that it has been awarded a new contract by Petrobras for the provision of stack-up mooring system services in Brazil. 

This work will support light-workover interventions and abandonment operations on installed subsea Christmas trees across both anchored and dynamically positioned Mobile Offshore Drilling Units (MODUs) and Well Intervention Vessels (WIVs). The assets are located in water depths from 80 to 600 metres. 

This three-year multi-million-dollar contract further reinforces our long-standing partnership with Petrobras and highlights the confidence placed in Acteon’s capabilities in Brazil.

A key strength of this award lies in the combined capabilities of three Acteon business lines coming together to deliver a fully integrated solution. 

• Intermoor will act as the contractor, managing project delivery, procurement, logistics, and all offshore mooring operations, including installation and retrieval of anchors, tethers, and subsea BOP interfaces.
• 2H, Acteon’s engineering consultancy, will provide engineering and analysis expertise, covering BOP tethering design support, sensor data integration, and both preoperation and realtime Global Riser Analysis, as well as the real-time riser monitoring system and General Mooring Design (PGA).
• UTEC, Acteon’s Geo-services business line, will deliver the hardware and software for real-time riser monitoring, supplying subsea load links, strain sensors, junction bottles, GNSS/INS units, and topside acquisition servers to enable accurate, real-time visualisation of riser behaviour. 

By integrating these three specialist business lines and combining mooring expertise, engineering intelligence, and advanced monitoring technologies, we’re delivering a safer, more efficient, lower risk solution aligned with Petrobras’ long-term goals. This approach also improves schedule efficiency and reduces environmental impact by enabling vessel loading directly from our Açu Port base.

We are proud of the tight collaboration between our teams and look forward to delivering this project safely and to the highest standards.
