Per-type check intervals & man-hour norms are editable under Coefficients below — shipped values are published-industry planning estimates, not OEM data.
| Base | Coverage | Min / shift | Rotation |
|---|
Min / shift = engineers required simultaneously on shift. Rotation doubles (6/6) or triples (2/4) the roster per position. Duty limits validated against IOGP-690 §25C.
Productive hours = nominal annual hours minus leave, training, sickness, admin. Typical offshore figure 1,400–1,600 h.
A >25% man-hour shortfall in a calendar month is a significant deviation that must be reported to the compliance monitoring manager and accountable manager.

Defaults are industry planning estimates for offshore/SAR utilization. Calibrate with your own history for authority submissions.
| Function | Workload MH/yr | By workload | By coverage | Required | Certifying |

Required per function = the higher of workload-driven and coverage-driven demand. Rotation patterns multiply coverage demand. Compliance monitoring shown at group level (0.5 FTE minimum, may be contracted).
The PDF states fleet, assumptions, per-function headcount, deviation status and methodology — the document a surveyor asks for under 145.A.30(d), and the evidence pack for IOGP-690 §25C customer audits.
