The verdict in three sentences
At 2,500 permits to work a year across 6 sites, an oilfield services company managed from London or Dubai reaches the point where paper is as much an audit liability as an operational drag. A custom permit-to-work and HSE tracking app usually lands in the medium band of Kolonell's grid, 4,000,000 to 7,000,000 FCFA, or complex if it connects to the client's ERP and CMMS, with a 3 to 5 month timeline. Payback is measured in crew hours recovered and audit findings avoided.
Permit types and steps to digitise
A permit to work is not a form, it is a sequence of controls signed by different people in a set order. The app must reproduce that sequence without cutting corners.
- Hot work: welding, grinding, cutting, with prior gas test and a named fire watch.
- Working at height: harness and anchor checks, rescue plan.
- Confined space entry: O2, H2S and LEL readings before entry and at intervals, standby person, entrant log.
- Isolation and de-isolation (LOTO): isolation points, padlocks, zero-energy verification.
- Sequential sign-offs: requester, issuing authority, area authority, performing authority, then close-out and hand-back.
- Near misses and unsafe conditions: reported in one minute from a phone, with photo, location and action tracking.
| Step | Paper (current state) | App |
|---|---|---|
| Preparing a permit | 25 to 40 min, triplicate pad | 8 to 12 min, templates by type |
| Collecting signatures | 1 to 3 h waiting for availability | Mobile notification, 15 to 30 min |
| Checking conflicts (2 permits in one area) | Supervisor memory | Automatic alert |
| Gas readings | Handwritten, sometimes after the fact | Time-stamped, blocking thresholds |
| Audit retrieval | Binders, hours of searching | Instant search, PDF export |
| Near-miss reporting | 30 to 80 a year (under-reported) | 3 to 5 times more reports expected |
Budget and timeline in 2026
For a London or Dubai buyer, the usual benchmarks are enterprise permit-to-work suites or a local agency build. As a 2026 order of magnitude, licensed suites charge around $40 to $120 per user per month plus $15,000 to $50,000 of configuration, and a bespoke build by a London agency typically runs £80,000 to £200,000. For 60 to 80 active users, licences alone exceed $60,000 a year. Kolonell's custom grid, quoted in FCFA and EUR:
| Level | Typical scope | Kolonell budget | Timeline |
|---|---|---|---|
| Simple | 3 permit types, sign-offs, archive, 1 to 2 sites | 2,500,000 to 4,000,000 FCFA (3,810 to 6,100 EUR) | 2 to 3 months |
| Medium | 6 sites, LOTO, gas tests, near misses, offline | 4,000,000 to 7,000,000 FCFA (6,100 to 10,670 EUR) | 3 to 4 months |
| Complex | CMMS, ERP and competency integration, group dashboards | 7,000,000 to 15,000,000+ FCFA (10,670 to 22,870+ EUR) | 4 to 5 months |
| Maintenance | Fixes, minor changes, backups | 35,000 / 75,000 / 120,000 FCFA per month (53 / 114 / 183 EUR) | Ongoing |
What auditors and operators will check
Operators impose standards close to ISO 45001 and their own permit rules on contractors, and UK firms will also be measured against HSE guidance HSG250 on permit systems. Three points come up in almost every audit:
- Traceability: who signed, at what time, with which competency valid on that date.
- Consistent readings: a confined space permit without a time-stamped gas test is a major finding.
- Learning loop: near misses must lead to actions tracked to closure.
The app must therefore block a sign-off when a competency has expired, refuse to activate a permit without compliant readings, and produce an exportable register for the auditor.

Omar, HSE manager of an oilfield services firm headquartered in Dubai, coordinates 6 sites, two of them offshore. His teams issue 2,500 permits a year. Waiting for signatures costs an average of 1.5 crew hours per permit, for a crew of 4 billed to the operator at $40 per person per hour.
Calculation: 2,500 permits x 1.5 h x 4 people x $40 = $600,000 of billable time tied up each year. If the app cuts waiting by one hour per permit, $400,000 of capacity is recovered. Even if only a tenth of that becomes real gain, a medium-band project at 6,000,000 FCFA (about 9,150 EUR) pays back within months, before counting contractual penalties avoided.
FAQ
Does the app work on an offshore platform without connectivity?
Yes, offline mode lets crews prepare, sign and close a permit on a tablet, then sync when connectivity returns. Area conflicts are checked locally against the last 30 days of permits for that site.
Can we keep our existing permit forms?
Yes, templates mirror your sections, gas thresholds and sign-off order. Configuring 4 to 6 permit types is included in the medium band.
Will electronic signatures stand up in an audit?
A time-stamped signature tied to a named account and a valid competency is generally accepted by operators. The format is agreed with your client in the first 2 weeks of the project.
How long does training take?
Allow half a day for issuing authorities and 1 to 2 hours for performing authorities. A 4-week pilot on one site precedes rollout to all 6.
Who hosts the HSE data?
Hosting is chosen with you, on a cloud region or a group server, and priced in the quote. Maintenance starts at 35,000 FCFA per month.
