FOSV Liftguide Tool
FOSV Liftguide Tool
Full Opening Safety Valve Handling Solution
The FOSV Liftguide Tool is a high-performance well control solution designed for the quick and reliable installation of the Full Opening Safety Valve (FOSV) during critical operations. By simplifying handling and reducing manual intervention, it enables faster response, lower non-productive time (NPT), and improved well control efficiency in high-risk drilling environments.

The Challenge
Conventional FOSV installation introduces failure points that slow the critical response window — with direct consequences for well integrity and personnel safety.
Challenge with Conventional Tools
1- Slow rigging-up
Tools stored away from the FOSV must be retrieved and attached under pressure — wasting critical seconds when influx is already underway.
2- Injury risk
Chain tong and pipe tong make-up methods expose hands and fingers to high-force pinch points during the most stressful moments on the rig floor.
3- Multi-crew dependency
Conventional methods require 2–3 personnel coordinating under stress — increasing scope for miscommunication and procedural error.
4- Cross-threading risk
Manual stabbing without a guide risks cross-threading the FOSV under pressure — compounding the emergency at the worst possible moment.

What is the FOSV Liftguide Tool?
Product Overview
The FOSV Liftguide Tool is a specialized mechanical handling system used to safely lift, guide, and position the Full Opening Safety Valve onto the drill string with high accuracy. It is engineered to ensure controlled alignment and secure engagement, even under time-critical and high-pressure conditions.
Unlike conventional methods that rely on multiple tools and manual coordination, this system integrates key handling functions into a single unit, allowing for consistent, repeatable, and error-free installation. Its design enhances operational safety by reducing human exposure, while also improving deployment speed—making it a vital tool for maintaining well integrity and effectively managing well control situations.

vs Conventional methods
Product Comparison
The performance difference is not marginal — it is the difference between seconds and minutes during a live well control event.
| Capability | Conventional methods | Voltaro FOSV Liftguide Tool |
|---|---|---|
| Readiness | Must be retrieved & rigged up under pressure | Pre-installed — zero setup time |
| Lifting method | Improvised slings or manual carry | Dedicated certified lifting point |
| Thread alignment | Manual stabbing — cross-threading risk under stress | Integrated guide — accurate alignment every time |
| Make-up method | Chain tongs — pinch-point hazard, multi-person | Handwheel — one operator, hands away from hazard |
| Personnel required | 2–3 crew members coordinating under stress | 1 operator completes full installation |
| Response speed | Delayed by tool retrieval & multi-step rigging | Seconds from decision to installed valve |
| SWL certification | Improvised methods lack SWL documentation | Full certified SWL — documentation included |
Built for Real-World Drilling Operations
Applications
Emergency Well Control — Live Well
Kick detected, well flowing through drill string. Lift by tugger, stab, make up — completed by one person in seconds without chain tongs or additional rigging.
Routine Well Control Drills
Faster, more realistic FOSV drills that build crew muscle memory and reduce measured response intervals — demonstrating preparedness to operators and regulators.
Offshore — Semi-Sub, Jack-Up, Drillship
Compact pre-installed design requires no additional deck space and is ready for action regardless of sea state, weather conditions, or time of day.
Onshore HPHT Operations
Robust construction performs reliably across temperature extremes and in the abrasive, fluid-rich environments typical of high-pressure, high-temperature wells.
Managed Pressure Drilling (MPD)
Supports rapid FOSV deployment across all well pressure regimes and operations requiring constant annular pressure management and elevated kick tolerance.
Operator-Specified Well Control Programs
Fully documentable and certifiable for integration into bridging documents, IWCF/IADC-aligned emergency response plans, and well control procedures.
