Not around ports.
Inside them for 18 years.
Limenis PreGate runs truck traffic inside and outside the port as one flow: booking, pre-validation, truck park, calls from the TOS and the automated gate.

The problem
Gate congestion is not a gate problem.
It is a planning problem.
However fast the gate is, trucks that arrive at random, leave with missing documents or are called to jobs that are not ready rebuild the queue.
Random
arrivals create queues at peak and idle capacity the rest of the day.
At the gate
a missing document, customs or payment issue blocks the lane.
Not ready
a truck sent to an unready job ties up the yard, the RTG and the driver.
Invisible
road: city traffic and park occupancy never enter the plan.
How it works
From the road to the yard,
one traceable journey.
From booking to exit, every event joins the same Visit ID: who, when, which plate, which container.
- 01
Booking
Slot, quota and tolerance window; capacity by job type.
- 02
Pre-validation
Customs, release, payment, VGM and driver match before the truck leaves.
- 03
Truck park
OCR/RFID entry, a bay that fits the truck, dwell tracking.
- 04
Call from the TOS
Load ready, block and equipment free: the truck is called at the right moment.
- 05
Automated gate
Identity + eligibility + safety → timed barrier command.
- 06
Operation and close-out
TOS move, exit permit, fee reconciliation and KPIs.
Platform
Twelve modules, one flow.
Each card shows where the module stands today. Start with all of them or with the ones you choose.

Traffic Engine
Call by capacity,
not by queue.
Vessel ETA, block and equipment plan, road load, park occupancy and each truck's expected arrival in one decision loop. The engine decides who comes now, who waits and who moves their slot.
R&D
Academically grounded optimisation
Slot optimisation, queueing models and traffic control algorithms were developed with university academic staff.
The models that solve capacity constraints with mathematical optimisation have been developed.
Queueing theory
Waiting in the park and at the gate; the lane count that keeps P90 under threshold.
Mixed-integer optimisation
Bookings per slot under gate, lane, job-type and yard constraints.
Stochastic arrival prediction
Real arrival time from live traffic and history.
Machine learning
Quota and turnaround forecasts from the port's own data.
Sample decision
6 places free in the yard. 4 trucks on the road.
The call budget does not only count free places; it reserves room for trucks on the way so capacity is never spent twice.
Suggestion: call at most 2 new trucks.
If job, permit and safety conditions hold. Entry rate and spacing are limited separately.
If job, permit and safety conditions hold. Entry rate and spacing are limited separately.
For every suggestion the operator sees: reason · data time · forecast confidence · constraints · model version · approval and rollback record.

The operations layer
that completes your TOS.
PreGate does not replace your port's systems. The TOS stays the single source of truth; every connection is installed, tested and accepted at your site.

The named systems are connection targets. No connector has passed customer acceptance yet; we will show version, message scope and acceptance result here as each one does. Customer acceptance: none yet.
Interface-first architecture: the gate logic never talks to a vendor API directly. Every connection is commissioned at your site and passes acceptance testing.

About us
Not a software firm entering ports.
Port managers who founded a software firm.
Limenis Technology was founded by a team that spent 18 years in container and multipurpose terminals as IT directors, IT managers, system architects and project leads. We ran the gate at 3 a.m. during vessel peaks, sat with customs when systems went down and moved a TOS without stopping a single crane. PreGate is the product we wished we had in those years.

Frequently asked questions
The critical questions from operations.
Do we have to replace our TOS?
No. PreGate complements the TOS, which stays the single source of truth. The TOS connection is installed at your site and passes acceptance testing.
What happens when the internet goes down?
The edge layer keeps permitted transactions and the event log running. A transaction that needs a current TOS or customs permit never proceeds as if it had one. If the TOS is unreachable, the last known hold status is used and recorded.
Do drivers have to install an app?
No. A responsive web page, a time-limited link and SMS/WhatsApp notifications are enough. Critical steps ask for identity verification.
Can we use our existing cameras and barriers?
Yes. Compatibility is checked during site analysis; existing devices connect to PreGate through the Edge component.
What do the 35 seconds cover?
One pre-validated lane transaction with no exceptions: from the truck stopping in the lane to the barrier opening. It does not cover the total port visit, park waiting or exceptions.
Where is the data kept?
Wherever you decide: on your servers, in a private cloud or hybrid. KVKK and GDPR duties are worked out for each installation.
Do hauliers pay?
The model follows the port's choice: slot fee, premium slot, no-show penalty or free.
How does a pilot start?
It starts with a site survey and baseline; a shadow run and controlled lane lead to acceptance in 12 weeks. Download the pilot information list and send it to us.
