Where a single voyage fragments
Shipping moves 12,720 million tonnes of cargo a year across 85,148 vessels crewed by 2.57 million people. It does this on an operational substrate of email attachments, PDFs, spreadsheets and a dozen systems that do not speak to each other.
Nobody set out to build it this way. It accreted, function by function, and the cost of it does not appear as a line item in any account — which is precisely why it persists.
Follow one supramax cargo from fixture to final accounts:
| Step | System | Handoff |
|---|---|---|
| Fixture agreed | Chartering desk, email recap | Re-keyed into operations |
| Voyage instructions | Operations system | Emailed to vessel |
| Port agency appointed | Email, agent's own system | Pro forma DA by email |
| Bunkers stemmed | Broker, supplier system | BDN scanned on board |
| Cargo loaded | Terminal system, mate's receipt | SOF signed and scanned |
| Noon reports | Vessel spreadsheet or PMS | Emailed daily |
| Emissions data | Reconstructed from noon reports | Compiled quarterly |
| Spares ordered | Purchasing system | Emailed to supplier |
| Crew changed | Crewing system | Travel booked separately |
| Wages paid | Payroll, then banking | Multiple correspondents |
| Disbursements | Agent's final DA | Reconciled manually |
| Demurrage claimed | Post-fixture spreadsheet | Documents chased from ship |
| Accounts closed | ERP | Re-keyed from all of the above |
The five costs, quantified where possible
1. Claims that expire. A fleet running 60 voyages a year with an average demurrage claim of USD 60,000 handles roughly USD 3.6 million in claims annually. A 5% failure rate — documents not collected before departure, time bar missed — is USD 180,000 lost for purely administrative reasons.
2. Payment friction. Crew allotments, port disbursements and supplier payments crossing correspondent banking chains lose value at every hop. Almost no operator measures what beneficiaries actually receive versus what was sent, which means the cost is invisible and therefore unmanaged.
3. Compliance rework. EU ETS now covers 100% of applicable emissions including methane and nitrous oxide; FuelEU Maritime measures well-to-wake intensity against a 91.16 gCO₂e/MJ baseline with pooling across ships. Both require fuel attributed to correctly classified voyages. Fleets reconstructing that quarterly from noon reports pay twice — once in labour, once in the errors.
4. Decisions made late. A hull performance problem visible in week two and acted on in week ten costs eight weeks of excess fuel and allowances. A cost variance identified at quarter end cannot be corrected within the quarter.
5. Reconciliation labour. People whose full-time job is making two systems agree. It is skilled work that produces no output beyond agreement.
What a maritime operating system would have to do
Not another module. A layer beneath the modules that holds the identities everything else depends on:
| Requirement | Why |
|---|---|
| One vessel identity | Keyed on IMO number; survives name and flag changes |
| One equipment register | Shared by PMS, purchasing and inventory |
| One seafarer record | Across recruitment, crewing, payroll, training |
| One voyage identity | Linking fixture, ports, fuel, emissions and cost |
| One counterparty record | Screened once, used everywhere |
| Event-driven flow | Commitments reach finance when made, not overnight |
| Machine-readable in and out | Data enters once and leaves in a usable form |
| Offline resilience | Ships lose connectivity; nothing may be lost |
| Auditability | Who changed what, when, and why |
| Data ownership by the owner | Portable on termination, in a documented format |
Everything else — dashboards, analytics, optimisation, AI — is built on top and is only as good as those ten rows.
Why now
Three things changed at once.
Connectivity. LEO satellite services removed the bandwidth constraint that shaped shipboard architecture for two decades. Live data from ships is now practical on ordinary cargo tonnage.
Regulation with a cash price. EU ETS and FuelEU turned data quality into a financial exposure. Fragmentation used to be inefficient; now it is expensive in a way finance departments can see.
Scarcity of people. With an officer shortfall of 39,100 and 113,735 more needed by 2030, neither ships nor offices have spare people to spend on re-keying. Administrative load is now competing directly with the work that actually needs doing.
What owners can do without buying anything
- Name owners for the five core identities — vessel, equipment, seafarer, voyage, counterparty
- Write down the definitions that get argued about: off-hire, available days, OPEX, retention
- Measure what beneficiaries receive versus what you send
- Build a claim register with time-bar alerting
- Capture voyage classification at the time, not at year end
- Publish a monthly data quality scorecard
- Insist on machine-readable export rights in every system contract
Most of the value in de-fragmenting a fleet is governance, not software. The software makes it durable; the governance makes it work.

Frequently asked questions
What is a maritime operating system?
A unified layer that holds the core operational identities — vessel, equipment, seafarer, voyage, counterparty — so that commercial, technical, crewing, compliance and finance functions work from the same record rather than from separate copies.
Is this just an ERP for shipping?
No. An ERP holds the ledger. An operating layer holds the operational reality that the ledger, the PMS, the crewing system and the emissions calculation all depend on.
What does fragmentation actually cost?
It does not appear as a line item, which is the problem. It shows up as lost claims, payment leakage, compliance rework, late decisions and reconciliation labour.
Where should a fleet start?
With the vessel register and the definitions. Both are cheap, neither requires procurement, and everything else depends on them.
