Energy & petroleum maritime operations
Bangladesh runs on imported petroleum products. Tankers deliver them to Chattogram's outer anchorage, with lighter tankers and oil berths beyond. For suppliers and traders, every delivery runs against fixed laytime, and an hour lost at the anchorage or the berth becomes demurrage. AMS gives tanker operators, suppliers, charterers and traders a local desk that watches that clock from nomination to final documents.
Typical BPC cargoes and laytime
| Product | Full cargo | Laytime allowed | Delivery |
|---|---|---|---|
| Gasoil 50 ppm (or + Jet A-1) | 30,000 MT (10,000 + 20,000 combination) | 120 running hours, FHINC | Outer anchorage, lightering to oil berth at seller's cost |
| HSFO 180 cSt | 25,000 MT ±10% | 108 running hours, FHINC | Vessel must come direct to jetty |
| Gasoline 95 unleaded | 25,000 MT ±10% | 108 running hours, FHINC | Vessel must come direct to jetty |
| Marine fuel 0.5% S | 15,000 MT ±10% | 84 running hours, FHINC | Vessel must come direct to jetty |
From a recent BPC international tender schedule. Berth draft at Chattogram oil berths is quoted there as 7–9 m, with LOA up to 186 m and a minimum discharge capacity of 700 MT per hour. Terms vary by tender.
Clean and dirty products
| Category | Products | What it means for the port call |
|---|---|---|
| Clean products | Gasoline, Jet A-1, Gasoil | Tank cleanliness and quality inspection matter most, and buyers look at the vessel's last three cargoes. These products usually discharge faster. |
| Dirty products | HSFO, fuel oil | Heating is needed to keep the product pumpable. Discharge is slower and stripping takes longer, so plan the call around it. |
Where demurrage is won or lost
| Risk point | What we do about it |
|---|---|
| NOR window | At Chattogram outer anchorage a BPC NOR counts only between 06:00 and 18:00. We time the arrival and tender NOR when the window opens. |
| Night navigation | If lightering cannot start on arrival because of the night navigation restriction, laytime waits until 06:00. We plan lighter tankers so the first hose connects at first light. |
| Shore rate restrictions | Terminal limits on rate and pressure confirmed before arrival, so the estimate is realistic. |
| Weather and tide | Stoppages for bad weather and low tide are excluded or counted at 50%, so we log every stoppage in the SOF. |
| Quantity and quality | The ship arrival figure is fixed by the independent inspector at the anchorage. We make sure tanks, ullages and samples are ready for the inspector. |
| Documentation | Cargo documents, survey reports and port papers prepared ahead of arrival. |
Before arrival, we ask the vessel
- Number and type of cargo pumps (deepwell or pump-room)
- Maximum discharge rate and pressure
- Manifold size and connections
- Cargo tank plan and ullages on arrival
- Heating temperature for HSFO / fuel oil
- Stripping pump capacity
- Arrival draft and trim
- Bunker ROB for the expected waiting time
Estimate the discharge
Discharge time estimator
A quick, indicative estimate of how long a tanker will take to discharge. This is the same first check our desk runs when a nomination arrives.
Indicative only. Actual discharge depends on shore pressure and line restrictions, cargo viscosity and heating, number of grades, weather and terminal procedures. Send us the vessel's Q88 and cargo plan for a proper estimate.
Documents we track
Tanker terms, in brief
- Ullage
- The empty space above the cargo in a tank, measured from the top. Ullages before and after discharge show how much has gone ashore.
- Ship arrival figure
- The quantity on board measured by the independent inspector on arrival at the outer anchorage. BPC uses it as the invoice quantity.
- NOR
- Notice of Readiness. The master's notice that the vessel has arrived and is ready to discharge.
- FHINC
- Fridays and holidays included: laytime runs every day.
- Laytime
- The time allowed in the contract to discharge the cargo.
- Demurrage
- The amount payable for time used beyond laytime.
- Stripping
- Pumping out the last cargo from the tank bottoms at a slower rate at the end of discharge.
- CFR
- Cost and Freight. The seller supplies the cargo and arranges the vessel to the discharge port.
