Make informed routing and logistics decisions by comparing harbor facilities, infrastructure, equipment, cranes, and shipping services across major maritime ports. Every comparison is built on verified data and updated regularly.
No comparisons match your search. Try a different port name or country.
Selecting the right port is one of the most consequential decisions in maritime logistics. Two ports serving the same trade lane can differ dramatically in draft, crane capacity, berth length, intermodal connectivity, congestion levels, and service quality — and these differences directly impact vessel turnaround, supply chain reliability, and total landed cost.
Side-by-side comparison turns scattered port data into a clear decision-making tool. Logistics managers, freight forwarders, supply chain analysts, and shipping line planners use port comparisons to evaluate alternative gateways, plan multi-port rotations, benchmark performance, and respond quickly to disruption.
Seadex provides the largest open index of port-to-port comparisons, built on verified harbor authority data, World Port Index records, and real-time operational signals. Each comparison page presents the same structured criteria so you can compare ports objectively, without navigating different reports or data formats.
Each port comparison covers six structured categories of harbor and shipping data, ensuring you can evaluate ports against the criteria that matter most for your operation.
Harbor type, channel depth, anchorage, tide range, shelter rating, and entrance restrictions — the physical characteristics that determine which vessels can call.
Comparisons are generated for ports within reasonable maritime proximity that are realistic alternatives for the same trade lane, plus all comparisons involving the world's top container hubs. This ensures the index focuses on practically meaningful pairings.
Maximum vessel size, berth length and depth, dry dock availability, and storage capacity for containers, bulk, and breakbulk cargo.
Throughput, turnaround time, congestion levels, berth occupancy, and historical reliability indicators sourced from real operational data.
Crane types and capacities, tug services, lift gear, mooring assistance, and other handling equipment available at each port.
Pilotage, towage, bunkering, ship repair, fresh water, provisioning, customs, medical, and other services available 24/7 or on demand.
Rail, road, and inland waterway connections, free trade zones, customs procedures, and onward routing options to the hinterland.
Every comparison on Seadex follows the same rigorous methodology, drawing from authoritative maritime data sources to ensure fairness and accuracy.
We aggregate data from the World Port Index (WPI), official harbor authority publications, UN/LOCODE registries, and live operational feeds — never third-party scraped content.
Each port is evaluated against the same 40+ structured criteria across six categories, so two ports can always be compared on equal footing without manual data harmonisation.
We compute great-circle distances between port pairs and surface the shipping routes that connect them, helping you understand whether the comparison reflects realistic alternatives.
Comparisons are regenerated regularly as port authorities publish new data and operational metrics shift — the page you read today reflects the most recent verified state.
We combine the World Port Index (WPI) maintained by NGA, UN/LOCODE registries, official harbor authority datasets, and operational signals such as AIS-derived congestion and turnaround metrics.
Static port characteristics (depth, berth dimensions, equipment) are refreshed when port authorities publish revisions. Operational metrics (congestion, turnaround) are updated continuously from live feeds.
Yes — most major and mid-sized ports are already covered. If you need a comparison that is not yet listed, contact our team and we will prioritise generating it.
All port comparison pages on Seadex are completely free, with no account or subscription required. They are built to support the maritime logistics community with open, verifiable data.
Sinay offers Safecube, Open Ocean, and Mobyo APIs that expose port, vessel, and operational data programmatically. Contact our team to discuss API access for your supply chain platform.
