No single public page publishes the Belawan port vessel schedule, which is worth knowing before you spend an afternoon looking for one. What exists is a clearance system agents file into, commercial trackers reading the ships’ own radio signals, and a berth plan held by the terminal. None of the three is a timetable.
This page sets out the five sources, what each gives you, and how to read an ETA against an ATA without planning a truck fleet around the wrong number. We develop an industrial estate next to this port, so the berth clock is a number we watch too.

Where the Belawan Port Vessel Schedule Actually Lives
The system of record is Inaportnet, the Ministry of Transportation’s electronic single-service portal for ship and cargo services, mandated by Ministerial Regulation PM 157 of 2015. Belawan Port was one of six first-phase ports named in Article 5, with Tanjung Priok, Tanjung Perak, Makassar, Tanjung Emas and Bitung. The portal covers ship arrival, shifting, departure, extension of berthing and cancellation, and it puts the harbourmaster, port authority, customs, quarantine, immigration and terminal operator on the same file.
What it is not is a public arrivals board. Access is for registered users, so the schedule reaches a shipper through their agent rather than a browser tab. A study of clearance at the Belawan harbourmaster’s office traces the chain that produces it: warta kapal and arrival application, pilotage and berthing orders, cargo handling plan, then the SPB that releases the ship.
The Five Sources, and What Each One Gives You
Five sources cover the question, and they rank by what you need: a firm berth time, or a position on a map.
| Source | What it shows | Who can see it | Lag |
|---|---|---|---|
| Inaportnet (Ministry of Transportation) | Filed arrival, berthing, shifting and departure applications | Registered agents, operators, agencies | Real time, by filing |
| Your shipping agent | The berth plan and your queue position | You, on request | Hours |
| Terminal operator (Pelindo Multi Terminal Belawan) | Berth allocation, gang assignment, discharge rate | Contracted users | Hours |
| AIS trackers (MarineTraffic, VesselFinder) | Position, course, speed, declared ETA, port call history | Public, name often behind a paid plan | Minutes, within receiver coverage |
| Harbourmaster (KSOP) Belawan | Clearance status, detentions, notices | On enquiry | Days |
The VesselFinder page for Belawan shows the pattern. It lists the port under its UN/LOCODE IDBLW with four tabs, expected, arrivals, departures and in port, but the vessel name on an expected arrival sits behind a subscription. Our guide to the Belawan port code explains why that five-character code opens every one of these lookups.
If you need the berth window rather than the map, call the agent first and treat the tracker as the sanity check. If you are evaluating the port rather than booking into it, our profile of the Port of Belawan covers the berths behind these numbers, and our logistics team can add the North Sumatra picture.
ETA, ATA and the Gaps Between Them
Four timestamps decide a cargo plan, and only three are facts. The distance between the forecast and the record is where demurrage is made.
- ETA, estimated time of arrival. A forecast, and on an AIS tracker whatever the bridge last typed in, so a stale ETA is common on a long leg.
- ATA, actual time of arrival. Arrival at the pilot station or anchorage. It starts the waiting clock, not the working clock.
- ATB, actual time of berthing. When the ship went alongside. ATA to ATB is berth waiting time.
- ATD, actual time of departure. When the ship sailed, after the SPB is issued.
AIS makes the first three visible because carriage is mandatory. Under SOLAS Chapter V Regulation 19, it must be fitted on all ships of 300 gross tonnage and above on international voyages, cargo ships of 500 gross tonnage and above on domestic voyages, and all passenger ships whatever their size, effective for all ships by 31 December 2004. A coastal barge below those thresholds will not appear at all, worth remembering before you conclude that a berth is empty.
Why Berth Waiting Time Costs You Money
Berth waiting time is the line a schedule hides, and the form your cargo arrives in moves it more than the sailing date does. Through August 2026, Pelindo Multi Terminal’s Belawan branch reported berth productivity of 1,722 tonnes per ship per day for general and bagged cargo against 6,110 for dry bulk, on volumes of 475,346 ton/m³ and 4.12 million tonnes.
Run a 10,000-tonne parcel through both. As bagged cargo it needs roughly 5.8 days alongside; as dry bulk, about 1.6 days. Same tonnage, same berth, three and a half times the occupancy, and every extra day is charter hire plus the risk of missing the next slot. That is the arithmetic behind bagging at the plant rather than the quay.
Keep three clocks apart. Waiting time runs from ATA to ATB, port stay from arrival to departure, and dwelling time is the cargo’s own clock after discharge. A terminal can look fast on port stay and still leave your cargo in the yard.
Frequently Asked Questions
Is there a public Belawan port vessel schedule?
No single official page publishes one. Inaportnet, the Ministry of Transportation’s clearance portal, holds the filed arrival and departure applications but is restricted to registered agents, operators and agencies. Public AIS trackers show positions and declared ETAs instead, and the shipping agent is the route to a firm berth time.
How do I track a ship arriving at Belawan?
Search the vessel by name or IMO number on an AIS tracker such as MarineTraffic or VesselFinder, or open the Belawan port page under its UN/LOCODE, IDBLW, and read the expected arrivals tab. Confirm anything you plan around with the agent, because AIS shows position, not berth allocation.
What is the difference between ETA and ATA?
ETA is the estimated time of arrival, a declaration entered by the master or agent and revised during the voyage. ATA is the recorded arrival at the pilot station or anchorage. The gap between them, and the further gap to actual time of berthing, sets your berth waiting time and demurrage exposure.
Why do ships wait to berth at Belawan?
Waiting reflects berth availability and the discharge rate for the cargo type, not the schedule. Pelindo Multi Terminal’s Belawan branch reported 1,722 tonnes per ship per day for general and bagged cargo through August 2026 against 6,110 for dry bulk, so a slow-handling parcel holds a berth longer and pushes the queue back.
Talk to SIIPE About Site Logistics
If you are reading Belawan’s vessel schedule because you are weighing a plant or a terminal in North Sumatra, the berth clock is half the question. The other half is how many hand-offs sit between berthing and your gate. SIIPE (Sumalacca Integrated Industrial and Port Estate) is a planned 5,600-hectare industrial estate, deep seaport and township in Medan Belawan, 4.7 km from Belawan Port, about 10 minutes by road, with around 840 hectares acquired. Its own Sumalacca Dry & Liquid Bulk Port is planned, not operational.
