Rigtec Wellservice delivers evolved heavy well intervention using innovative, efficient, and environmentally responsible RoboRig technology.

Riserless Heavy Subsea Well Intervention System

Neutral Impact on Wellhead Fatigue
RoboRig™ adds no additional wellhead fatigue due to riserless operation where only vertical force is applied.

Riserless Heavy Well Intervention
RoboRig™ delivers full heavy subsea well intervention capability without risers, HWIVs, or MODUs

Cost Effective Plugging
Expensive with today’s methods, RoboRig™ makes subsea plugging practical, economical and safe.

Unlock Deferred Production
Unlock/optimize production from unproductive wells, unaccessible with current technology due to cost or fatigue.

Area of Use

Rigtec Wellservice utilizes RoboRig™ technology to transform heavy subsea well intervention across offshore installations.

Heavy subsea well intervention faces major barriers including wellhead fatigue, low operational limits, and high operational cost.

Rigtec Wellservice uses the riserless RoboRig™ system, which applies zero added wellhead fatigue — unlocking deferred production from unproductive wells or enabling cost-effective plug and abandonment.

    • Compact, High-Output Modular Design
      Lightweight yet industrial-strength, Roborig’s modular architecture replaces bulk with agility—ideal for tight sites and high-mobility deployments.

    • Unmatched Tripping Speeds (up to 1,800 m/h)
      Robotic drive systems enable 0.5–0.75 m/s equipment movement, cutting well intervention time dramatically.

    • No Vertical Pipe Rack Required
      Innovative handling eliminates the need for vertical racking, reducing rig height, complexity, and footprint.

    • Full Robotic Automation
      Executes entire drilling and workover sequences without human input—repeatable, precise, and programmable for all operations.

    • Universal String Compatibility
      Seamlessly handles all casing, tubing, and specialized strings—supporting a wide range of well designs and intervention scopes.

    • Significant Reduction in Drilling & Intervention Costs
      Outperforms optimised traditional rigs through time savings, automation, and reduced personnel requirements.

    • Optimised for Pad Drilling & Multi-Well Strategies
      High-density pad applications benefit from Roborig’s compact profile and continuous performance, enhancing ROI per location.

    • Rapid Deployment & Redeployment
      Modular system reduces rig-up/rig-down times and simplifies logistics, unlocking faster field-to-field mobility.

    • Lower Fabrication & Lifecycle Costs
      Smart materials, streamlined components, and fewer mechanical failure points translate into significantly reduced CAPEX and maintenance spend.

    • Less Diesel Consumption
      The hybrid diesel-electric system dramatically reduces emissions and fuel dependency, future-proofed with grid and renewable integration.

    • 200–300 kW Power Consumption
      Less than half the energy draw of traditional rigs, enabling operations in power-constrained or off-grid environments.

    • Minimal Surface Footprint
      Ideal for environmentally sensitive areas—reduces pad size, earthworks, and ecological impact.

    • Regenerative Braking & Energy Capture
      Captures kinetic energy during down cycles to power torque-intensive processes, boosting efficiency and lowering net consumption.
