Vessels arriving at congested ports can wait days for a berth while shipping lines have little visibility into their real queue position or expected wait. Cerulea anchors berth occupancy and queue data into a verified, real-time view that lines use to plan arrivals and cut idle time.
Replace a blind waiting game with a verified, shared view of berth availability and queue position.
01.
Publish real occupancy. The Provenance Notary anchors each berth's occupied or free state as it changes, giving every line one verified picture instead of rumor and phone calls.
02.
Show each vessel where it stands. The contract maintains an ordered, tamper-evident queue so a line can see its true position rather than guessing at expected wait.
03.
Turn visibility into savings. Lines use the verified queue to slow-steam or retime arrivals, cutting fuel burn and idle waiting outside a congested port.
04.
Make berth assignment auditable. The Audit Logs module records every allocation decision, so a line can confirm assignment order was fair and unmanipulated.
05.
Warn before the wait grows. The Notifications module signals lines when queue depth or expected wait crosses a threshold, so schedules adjust before delays compound.
06.
Give the port authority one shared board. All lines and the terminal read the same allocation state, reducing disputes over who was promised which berth and when.
Follow a single vessel from arrival declaration through queue positioning to a transparent berth allocation.

Cerulea decomposes berth transparency into modular contracts. Each layer declares, queues, releases, and allocates without any single party quietly reordering the queue.
Verified berth transparency is a horizontal capability. Here is how different maritime actors put the shared view to work.
Read a true queue position and expected wait to retime arrivals and slow-steam into congested ports, cutting fuel burn and idle demurrage on every rotation.
Key Asset Types
Run one shared allocation board that all lines trust, reducing disputes over berth promises and giving a defensible, auditable record of every assignment.
Key Asset Types
Plan trucking and yard capacity against verified berth timing, so onward moves are scheduled to real availability instead of speculative vessel ETAs.
Key Asset Types
Whether you are bridging a terminal operating system or letting lines read queue state from a planning portal, Cerulea routes both into one shared berth record.
For ports on legacy terminal operating systems. Existing berth and vessel events are translated into signed on-chain occupancy and queue updates through the API gateway automatically.

Building a verified berth transparency platform with live occupancy anchoring, tamper-evident queueing, and auditable allocation from scratch requires specialised maritime engineers and long integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects port-systems integration benchmarks. Connecting a terminal operating system, building custom queue-ordering and occupancy logic, and shipping an auditable allocation board for an average port takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your queue and allocation rules into pre-audited WebAssembly binaries and provisions the shared berth ledger instantly.
