What you will learn
- What offshore crew logistics involves: rotations, transport and beds
- How certification, medical fitness and training are checked before travel
- How helicopter and vessel transport is planned against weather and capacity
- How accommodation and mustering are managed on the platform
- Where logistics ends and human resources begins
What this project is
Offshore platforms are staffed in rotations: crews work offshore for weeks, then return home for time off. Managing that cycle involves transport by helicopter or vessel, accommodation in limited platform beds, and checks that each person is certified, medically fit and trained for the work they will do. A logistics system holds the rotation plan, the personnel records, the transport bookings and the bed plan together, so the platform is neither overmanned, with people sleeping in corridors, nor undermanned, with critical roles unfilled.
Certification and medical checks are safety gates, not admin. A person whose survival training has expired, or whose medical certificate has lapsed, must not travel offshore, however urgent the need. The system should block travel for expired certifications and flag approaching expiries in time for renewal. Weather adds uncertainty: helicopter flights are cancelled in bad weather, and the system should handle re-planning when transport is disrupted, showing who is stuck offshore, who is stuck onshore, and what that means for the next rotation.
Core features
- Rotation planning by role, team and platform, with shift patterns
- Personnel records with certifications, medical fitness, training and expiry dates
- Transport booking for helicopter and vessel, with capacity and weather handling
- Bed and cabin planning against platform accommodation capacity
- Travel blocking for expired certifications or medicals, with renewal alerts
- Mustering and personnel-on-board records, showing who is on the platform now
How it is built
- Map the platforms, roles, rotation patterns and transport routes first
- Build personnel records with certification and medical checks, then rotation planning
- Add transport booking and bed planning, then travel blocking for expired items
- Add personnel-on-board and mustering views, tested in emergency exercises
- Pilot on one platform for one rotation cycle, checking bed and transport accuracy
Technology considerations
Certification data must be current and trustworthy. Training providers, medical examiners and employers all feed the record, and the system needs a process for verifying records, not just accepting them. Expiry handling needs care: a certification that expires mid-rotation should be flagged before travel, not discovered offshore. Transport planning needs weather integration: flights planned without weather awareness will be cancelled routinely, and the system should show weather risk for planned flights, so re-planning starts early.
Personnel-on-board data is safety-critical. In an emergency, the platform must know exactly who is aboard. The system should maintain that list from transport and mustering data, with discrepancies flagged immediately. Data sensitivity matters: personnel records contain medical and personal data, so access must be role-based and retention agreed. The system should also handle contractors, who may work for several operators, without duplicating their records across platforms.
For the first version, run one platform's rotation for one full cycle: personnel records with certification and medical checks, transport bookings, bed plan and personnel-on-board list, tested in a mustering exercise. Platform managers judge the system on whether nobody travels with an expired certification and nobody arrives to find no bed. A system that passes one rotation, including a weather disruption, is ready for other platforms.
Challenges to plan for
- Personnel travelling with expired certifications, because checks were manual
- Beds overbooked because rotation changes were not reflected in the bed plan
- Transport disrupted by weather, leaving critical roles unfilled offshore
- Personnel-on-board lists that do not match who is actually on the platform
Who it is for, and its limits
This suits an offshore operator, a platform manager or a crewing company. It fits platforms with regular rotations and limited accommodation. It does not fit a small onshore facility with daily commuting, and it is not a human resources system: it manages offshore logistics, employment and pay stay in HR.
A logistics system does not crew a platform by itself. Crewing depends on available, certified people; the system makes the logistics of getting them offshore, housed and home again manageable. Costs vary with platform count and personnel numbers, so confirm with a quote after the rotations are mapped.
Frequently asked questions
What is personnel-on-board?
The live list of everyone currently on a platform, from transport and mustering data. It is the basis for emergency mustering and for knowing who is offshore at any time.
What blocks travel?
Expired or missing certifications, lapsed medical fitness, or missing training for the assigned role. The system blocks travel until the item is renewed, with the reason shown.
How is weather handled?
Flights and vessel sailings are planned with weather risk visible. When weather cancels transport, the system shows who is affected on both sides and supports re-planning the rotation.
How are beds planned?
Against platform accommodation capacity, by cabin type and team. Rotation changes update the bed plan, so overbooking is flagged before people travel, not on arrival.
Can contractors be managed?
Yes, with their records held once and used across platforms where they work, subject to access controls. Each operator sees the contractor data relevant to their platform.
