PORT CALL OPTIMISATION: The digital mooring
What happened
The International Maritime Organization's Facilitation Committee approved a Port Call Optimisation (PCO) Guide that standardises port-call definitions and creates an auditable framework. The guide targets consistent data and measurement across ports, addressing a major source of forecasting error where many port calls still require physical paperwork. Watch adoption on your priority lanes and terminals to see when data feeds become contractually usable
Buyer takeaway
Treat the PCO Guide as a new contractual reference point: require data SLAs where lanes matter because auditable port-call data reduces execution ambiguity
Cost / money
Potential to lower demurrage and idle costs over time; expect upfront integration and change-control expense to capture those savings
Supplier / commercial
Terminals and carriers that offer PCO-aligned feeds will gain advantage in negotiations; use this to extract service commitments
Safety / operations
Better coordination reduces rushed operations and paperwork-related handoffs that can cause safety incidents or delays
What to watch
Adoption will be phased and uneven; verify actual data availability and formats on each critical port before changing SLAs
Key facts
- IMO FAL approval of a Port Call Optimisation Guide
- Industry reports show many ports still require physical paperwork
- Guide creates auditable, standardised port-call definitions

With the approval of the PCO Guide, the IMO has moved beyond recommendations to establish an auditable framework — one that begins to turn port standards into actionable supply chain intelligence. A Common Language for Port Calls — At Last One of the longstanding challenges in measuring port performance has been deceptively simple: definitions
Key timestamps — Planned Time of Arrival (PTA), Estimated Time of Arrival (ETA), Actual Time of Arrival (ATA), and Requested Time of Arrival (RTA) — now carry consistent meaning across IMO member states. These are no longer just acronyms; they form a common language for port call data
A recent International Association of Ports and Harbors report highlighted that in more than 60% of port calls, authorities still require physical paperwork — despite the IMO’s Maritime Single Window mandate coming into effect on 1 January 2024
