Indonesian thermal-coal freight: what actually drives the voyage
For a coal stem, the commercially useful question is not simply “how far is it?” Parcel size, exact load and discharge points, geared versus gearless requirements, draft, loading/discharge rate, laycan, bunker assumptions, waiting time and vessel position can all change the freight outcome.
CharterPulse starts by comparing Supramax and Ultramax, then tests Panamax/Kamsarmax where the ports can genuinely use the larger class. On the current nominal planning DWTs, 50,000 MT is about 91% of Supramax DWT and 79% of Ultramax DWT. That is a planning comparison only—not a statement of actual cargo intake.
50,000 MT coal: compare the parcel against the class
| Planning class | CharterPulse nominal DWT | 50,000 MT / nominal DWT | Planning interpretation |
|---|---|---|---|
| Supramax | 55,000 | 90.9% | Close to nominal capacity; actual intake margin, bunkers, draft and vessel particulars matter. |
| Ultramax | 63,000 | 79.4% | Strong first-pass parcel fit in the CharterPulse comparison model. |
| Panamax | 76,000 | 65.8% | More spare DWT; economics depend on whether the larger ship and ports justify it. |
| Kamsarmax | 82,000 | 61.0% | Potentially workable but usually needs a port/cost reason to prefer the larger class. |
Nominal class figures are CharterPulse planning defaults. Actual vessel intake can be lower or higher depending on the nominated ship, bunkers, stores, draft, cargo density and port restrictions.
The inputs worth confirming before asking the market
Indonesia coal stems may depend on the actual terminal, jetty or anchorage rather than a broad city/port label.
Confirm the parcel, grade/specification and any cargo-condition or acceptance information relevant to the voyage.
Gear, grabs, shore equipment and productivity assumptions can affect both vessel suitability and time exposure.
A larger class only helps if the nominated load and discharge facilities can accept the ship at the required intake.
Prompt or firm timing changes which ships may realistically fit the stem and can move commercial appetite.
For short regional voyages, a few extra port days can materially change unit freight economics.
Indonesia → Philippines coal route intelligence
CharterPulse currently maintains 15 canonical coal planning routes from Samarinda, Balikpapan and Banjarmasin into Subic, Manila, Batangas, Cebu and Davao. The route pages combine distance and vessel economics with destination-port intelligence where authoritative updates are available.

Port intelligence can matter as much as the sea leg
A freight model should not freeze port costs or operating assumptions when an authority has issued a newer tariff, restriction or operational notice. CharterPulse keeps those developments on living port pages and leaves the estimator inputs editable until the actual terminal/agent pro forma is known.

Frequently asked planning questions
What vessel class should I compare for 50,000 MT of coal?
Start with Supramax and Ultramax. In the current CharterPulse planning defaults, Ultramax provides a more comfortable nominal-DWT utilisation for 50,000 MT, while Supramax is closer to nominal capacity. Actual selection still depends on the specific vessel, port draft, gear, cargo intake and market position.
Does a bigger vessel always mean cheaper freight per tonne?
No. More DWT can improve theoretical unit economics, but a larger vessel can lose that advantage through poor parcel utilisation, port restrictions, extra waiting, unsuitable gear, or a less favourable vessel position.
Does CharterPulse show a live coal freight quote?
No. CharterPulse produces a market-calibrated planning range: transparent voyage economics adjusted by bounded current market evidence. Use the market-check workflow when you need executable owner ideas, suitable tonnage or broker follow-up.
