Confined space entry — VR training for vessel, column and drum operations.
Confined space remains the highest-fatality-rate procedure in oil and gas globally. Across 100+ years of refinery operation, the technical procedure is well understood — the failures are operator-readiness, attendant attention, and complacency.
Across Drona VR's refinery deployments, confined-space-related near-miss reports rose 2–3× in the first 90 days post-rollout — and that is the goal. Operators who have rehearsed confined-space scenarios at full sensory intensity report incidents earlier and more often. The lagging indicator (lost-time incidents) drops in the second half of year one as the leading-indicator improvement compounds.
The 4 confined-space scenarios Drona VR covers
The default scenario library covers OISD-RP 105 / API RP 2015 / OSHA 1910.146-aligned confined-space training for refinery operations:
- Vessel entry — pre-entry atmospheric testing, isolation verification, attendant role
- Column entry — multi-level entry, ventilation continuous monitoring, retrieval rig
- Drum entry — short-duration entry, single-attendant handling
- Emergency egress — entrant unconscious, attendant retrieval protocol, cascade response
Implementation timeline — confined space module
Confined-space VR rollout is best run as a 12-week wave aligned with the next planned shutdown / turnaround cycle, when the highest concentration of vessel and column entries will occur.
What to measure in the first 12 months
Confined space metrics improve in two phases — leading indicators in months 1–6, lagging indicators in months 6–12:
- Near-miss report frequency (rises in months 1–3, normalises after 6)
- PTW rejection rate at issuance (rises as operators reject incomplete permits)
- Attendant-role assessment scores
- Rescue-drill cycle time (target: under 4 minutes from alert to entrant reach)
- Lost-time incidents related to confined space (lagging — months 6–12)
