Eliminate umbilicals and hydraulics to help improve safety, cut rig time, and deliver wireless subsea control
talk to an expertThe enhanced remote operated completion system (eROCS) removes traditional umbilicals and hydraulic power units (HPUs) to help reduce rig time, minimize red zone exposure, and optimize offshore efficiency. Built on field-proven technology, the system provides wireless control, advanced monitoring, and unmatched versatility for both live and dead wells.
Core advantages for subsea efficiency:
Traditional systems rely on large topside spreads and HPUs. These components increase rig-up time, require significant deck space, and expose personnel to high-pressure zones. eROCS removes these to help free valuable topside footprint and reduce operational risk. Operators remove umbilicals and HPUs to simplify mobilization, cut costs, and improve crew safety during completion and intervention campaigns.
Operate tubing hanger running tools (THRT), test trees, and downhole functions remotely with high-speed wireless communication (typically under one second response time).
Advanced valve packs combine pressure regulation and leakage detection in a single unit, supported by integrated flow and temperature sensors for real-time diagnostics.
The short length fits below blowout preventer (BOP) pipe rams, reducing rig-up complexity and improving flexibility. Modular design adapts to customer-specific requirements.
Fully redundant batteries with subsea trickle charging and multiple wired or wireless communication options help ensure operational continuity.
Operators face increased pressure to simplify subsea completions, reduce crew exposure, and accelerate complex campaigns. This completion system simplifies deepwater operations, reduces personnel in live well environments, and optimizes rig time for complex projects. The system also integrates with advanced orientation technologies such as the Optime tubing hanger orientation system (OTHOS) to achieve accurate alignment without additional hardware.
