Overview
Halliburton (NYSE: HAL) and aker BP have successfully completed the frist operation utilizing the Enhanced Remote Operated Control System (eROCS) and Optime Tubing Hanger Orientation System (OTHOS) on the Norwegian continental shelf. This milestone, announced on october 16, 2025, signifies a major advancement in Halliburton’s subsea operations,paving the way for wider adoption of digital control and umbilical-less solutions in offshore environments.
Breakthrough in Subsea Control and Completions
The prosperous operation represents a meaningful leap forward in subsea control and completions technology. The combination of digital hydraulic control, provided by eROCS, and the precise positioning capabilities of the OTHOS system allowed for the accurate installation and orientation of the vertical Christmas Tree tubing hanger without the need for traditional umbilical cables. This reduces complexity and potential failure points in subsea infrastructure.
Traditional subsea operations ofen rely on extensive umbilical cables to transmit power and control signals. These cables are expensive to install, maintain, and can be vulnerable to damage. eROCS offers a solution by enabling remote control of subsea equipment using digital hydraulic technology, minimizing the need for these physical connections.
eROCS and OTHOS: Key Technologies
Enhanced Remote Operated Control System (eROCS)
Halliburton’s eROCS is a digital hydraulic control system designed for subsea applications. It allows operators to remotely control subsea equipment with increased precision and reliability. Key benefits of eROCS include:
- Reduced reliance on umbilical cables.
- Improved control and responsiveness.
- Enhanced safety through remote operation.
- Lower overall project costs.
Optime tubing Hanger Orientation System (OTHOS)
The Optime OTHOS is a system designed for the precise installation and orientation of tubing hangers in subsea wells.It ensures accurate alignment, which is critical for the integrity and performance of subsea completions. The OTHOS system contributes to:
- Accurate tubing hanger positioning.
- Reduced installation time.
- improved well integrity.
Collaboration with Aker BP
This achievement is a direct result of the collaborative efforts between Halliburton and Aker BP. Aker BP,a Norwegian oil and gas operator,has been a key partner in the development and testing of these innovative technologies. Their commitment to adopting cutting-edge solutions has been instrumental in bringing eROCS and OTHOS to fruition.
Aker BP’s focus on digital transformation and subsea factory concepts aligns with Halliburton’s vision for the future of offshore operations. This partnership demonstrates the value of collaboration in driving innovation within the energy industry.
