Aker BP and Halliburton Execute First Umbilical-Less Tubing Hanger Installation
Halliburton (NYSE: HAL), in partnership with Aker BP, executed the first field operation using the Enhanced Remote Operated Control System (eROCS) with the Optime Tubing Hanger Orientation System (OTHOS) on the Norwegian continental shelf on October 16, 2025.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
The operation marked a breakthrough in subsea control and completions. The use of digital hydraulic control and the OTHOS allowed the precise installation and orientation of the vertical Christmas Tree tubing hanger without umbilicals, conventional tubing hanger orientation tools, or standard blowout preventer alignment equipment. The approach simplified planning and interface requirements, reduced operational complexity, lowered risks and costs, and increased rig flexibility for Aker BP.
"This milestone moves the entire subsea industry forward and opens up new possibilities once out of reach," said Josh Sears, senior vice president, Halliburton Drilling and Evaluation. "The successful installation reflects years of effort, bold ideas, and close teamwork with Aker BP. eROCS offers customers a solution for umbilical-less tubing hanger installation in every major offshore region and creates the opportunity to maximize value for our customers."
"At Aker BP, we are committed to innovation that creates safer, more efficient, and more sustainable operations," said Mads Rødsjø, vice president, Drilling and Wells, Aker BP. "The successful eROCS operation is a testament to this ambition. Together with Halliburton, we have taken a major step towards digital subsea control—one that will benefit not only our projects, but the wider industry."
With eROCS now field-validated, operators gain a new tool to reduce complexity and cost with improved control in offshore environments. This successful installation establishes eROCS as a proven solution for subsea well operations and signals a shift toward digital control within offshore markets.
