Halliburton, in collaboration with Norwegian oil operator Aker BP, has successfully completed the first installation of a tubing hanger without an umbilical using the Enhanced Remote Operated Control System (eROCS) and the Optime Tubing Hanger Orientation System (OTHOS). This operation, carried out on the Norwegian continental shelf, marks a technical advancement in subsea completion installations without the use of traditional equipment.
An operational shift in offshore installations
The installation was executed without the use of an umbilical, conventional tubing hanger orientation tools, or standard blowout preventer alignment equipment. The use of digitised hydraulic control enabled precise orientation of the tubing hanger on a vertical Christmas Tree. This approach reduced operational complexity, streamlined interface requirements, lowered costs and risks, and increased the flexibility of the rig used by Aker BP.
Field validation of the eROCS system opens the possibility for large-scale deployment across major offshore regions. By integrating digital and umbilical-less components, this technology is changing industry standards for deepwater completion operations.
A ready solution for international markets
Halliburton stated that this solution is now applicable in all major offshore regions, offering an operational option to operators seeking to reduce logistical constraints. The use of a fully digital system simplifies complex drilling campaigns and enables more direct control of subsea components.
According to available information, this project represents several years of joint technological development between the two companies. It enhances Halliburton’s ability to provide completion services without heavy infrastructure in high-demand technical environments.
