Proven completions subsea control system

Halliburton, in alliance with Optime Subsea ASA, delivers the remotely operated control system (ROCS)—a first-of-its-kind subsea control system. The ROCS electrohydraulic control system was developed with industry-proven components that provide robust and flexible completion landing string solutions.

Industry-first umbilical-less landing control

ROCS removes the need for reelers, control umbilicals, and hydraulic pressure units (HPU), which drives increased operational safety and efficiency, reduced rig footprint, and smaller crew size for offshore completion and intervention operations. The in-riser ROCS module is remotely controlled topside using an advanced telemetry control unit in conjunction with Halliburton’s DynaLink® Wireless Acoustic Telemetry System. ROCS provides improved digital functionality through a custom Human Machine Interface (HMI), without the use of traditional surface controls. 


  • No umbilical required, resulting in safer deployment
  • Eliminates 40+ tons of equipment for operation, reducing carbon footprint
  • Reduced topside footprint and personnel required to operate
  • Downhole data acquisition including well parameters and volumetric feedback on tubing hanger running tool (THRT) and smart well functions
  • Improved technical and operational risks equating to less downtime
  • Minimizes operations HSE risk by removing personnel from the red zone
