Surface riser systems designed for efficient well access

Our surface riser systems are engineered to provide reliable well access between the rig and the wellhead or BOP across drilling, intervention and abandonment operations. Using Aquaterra Energy’s quick-connect technology, these systems reduce connection time, improve offshore safety and minimise operational risk, delivering measurable efficiency gains compared to traditional flanged surface riser connections.

Fast, safe surface riser connections for offshore operations

Our surface riser systems replace traditional API flanged connections with a faster, safer and more efficient connection method. By utilising Aquaterra Energy’s quick-connect interface, the system enables rapid, repeatable make-up and break-out while maintaining a secure, gas-tight metal-to-metal seal.

This significantly reduces rig time, lowers manual handling and dropped-object risk, and improves overall operational efficiency. The system is suitable for drilling, intervention and abandonment operations and can be configured for a wide range of platform layouts and well types. Manual or hydraulic running tools are available to suit rig configuration and operational requirements.

Rapid make-up & break-out

Our AQC-BC connectors reduce surface riser make-up from hours to minutes, delivering immediate rig-time savings.

Improved safety offshore

Our quick, repeatable make-up reduces rig time and eliminates tubular running services, improving efficiency during intervention and workover campaigns.

Flexible configuration

Our surface riser systems can be supplied as standalone components or as complete connection and running packages.

Proven well access delivery across offshore drilling and intervention projects

Our surface riser systems have been deployed across a wide range of offshore projects, supporting drilling, intervention and abandonment activities on platform and jack-up operations. By simplifying surface connections and reducing offshore handling time, our systems help operators improve safety, reduce rig time and achieve consistent performance across repeated campaigns. Supported by our in-house engineering and analysis teams, surface riser systems form a core part of Aquaterra Energy’s well access capability, enabling efficient operations throughout the life of the well.
