Bunker Report

Download PDF Open the original PDF guideline

The Bunker Report records every bunker lifting — fuel supplied from a barge, ex-pipe from a terminal, or ship-to-ship from another vessel. It is submitted in addition to the usual Noon / Arrival / Departure reports for the same day, never as a replacement.

When to send: At the completion of every bunkering, before the next scheduled performance report.

Note

The submission flow (Submit → copy encoded block → paste into a plain-text Outlook email) is the same as for every other Metaweave form. See the Forms Guidelines → Submission of Metaweave Forms for the email template, recipient list, and subject-line rules.

Bunker Event Timeline

flowchart LR
    A[Barge Alongside] --> B[Bunker Hose Connected]
    B --> C[Commenced Bunkering]
    C --> D[Bunkering Completed]
    D --> E[Bunker Hose Disconnected]
    E --> F[Barge Cast Off]

All six timestamps must form a monotonic chain — each event must be at or after the previous one. The validation layer will block submission if they are out of order.

Fuel Type & Quantity Lifted

Add one row per fuel grade lifted.

BDN row fields

Field	Meaning
Fuel Category	Drop-down — HSFO, VLSFO, VLSFO (≤40 cSt), LSMGO, ULSFO, etc.
BDN Number	Bunker Delivery Note number from the supplier.
BDN Quantity	Quantity per the BDN, in MT.
Vessel Received Quantity	Quantity per the vessel’s own measurements, in MT.
Viscosity	From the BDN / Certificate of Quality.
Density	From the BDN / Certificate of Quality.
LCV	From the BDN / Certificate of Quality.
Sulphur %	From the BDN / Certificate of Quality.
Water %	From the BDN / Certificate of Quality.

Bio Fuel and Blends

When the BDN delivers a biofuel or a blended grade (a fossil base mixed with one or more bio components), use the + Add Bio Fuel button below the Fuel Type table. There are two cases:

BDN delivers	What to enter
Pure bio fuel (e.g. 100 MT HVO)	One parent BDN row + one Bio Fuel entry tagged with the bio category. No blend dialog.
Blend of fossil + bio (e.g. 500 MT B30 of VLSFO + FAME)	One parent BDN row + one “Blend” Bio Fuel entry + one component row per blended fuel (2–3 components allowed). Component quantities must sum to the parent BDN quantity.

Add BioFuel dialog fields

Field	Meaning
Vessel Code	Auto-populated from settings.
Bunkering Port	Auto-copied from the main bunker report header.
Bunkering Date / Time	Auto-copied from the parent BDN row.
BDN Number	Same BDN number as the parent row — links the bio fuel entry to the parent BDN.
BDN Quantity	Total BDN quantity in MT. For a pure bio delivery this is the bio quantity itself; for a blend this is the total delivered including the fossil base.
Fuel Category	Select Blend if the BDN is a mixture, or pick the specific bio category for a single bio fuel (see list below).

Supported bio fuel categories:

Code	Name
(ETH)	Ethanol
(BD)	BioFT-Diesel
(HVO)	Hydrotreated Vegetable Oil
(LBM)	Liquefied Bio-Methane
(BM)	Bio-Methanol
(PVO)	Pure Vegetable Oil
(DME)	Dimethyl Ether
(BH2)	Bio-H2
(ED)	e-diesel
(EM)	e-methanol
(ELNG)	e-LNG
(ELPG)	e-LPG
(EH2)	e-H2
(ENH3)	e-NH3
(EDME)	e-DME
(FAME)	FAME Diesel
(HTL)	Hydrothermal Liquefaction Oil
(UPO)	Upgraded Pyrolysis Oil
(UCO)	Used Oils and Fats
(ALO)	Algae Oil

Blend Component dialog fields

Field	Meaning
Blend Component 1	First component fuel type — the fossil base (e.g. (VLA80)VLSFO>80, HFO, LFO, MGO). Mandatory.
BDN Quantity (Component 1)	Quantity of the first component in MT. Mandatory, must be > 0.
Blend Component 2	Second component — usually the bio part (e.g. (FAME) Diesel, (HVO)Hydrotreated Vegetable Oil). Mandatory.
BDN Quantity (Component 2)	Quantity of the second component in MT. Mandatory, must be > 0.
Blend Component 3	Optional third component for a ternary blend. Leave as None for a 2-component blend.
BDN Quantity (Component 3)	Required only if Component 3 is set.

Caution

The sum of all component BDN quantities must equal the parent BDN Quantity from the Add BioFuel dialog. The shore pipeline computes the bio percentage from component masses — do not enter percentages, only mass in MT.

Worked Examples

Scenario	BDN Qty	Component 1	Component 2	Component 3
Pure HVO bunker	100 MT	(no blend dialog — pick (HVO)… as Fuel Category)	—	—
B24 FAME / VLSFO bunker	500 MT	(VLA80)VLSFO>80 380 MT	(FAME) Diesel 120 MT	None
B30 FAME / VLSFO bunker	500 MT	(VLA80)VLSFO>80 350 MT	(FAME) Diesel 150 MT	None
Tri-fuel HFO + HVO + FAME	800 MT	HFO 600 MT	(HVO)Hydrotreated Vegetable Oil 100 MT	(FAME) Diesel 100 MT
Pure UCO bunker	80 MT	(no blend dialog — pick (UCO)… as Fuel Category)	—	—

Editing or removing a Bio Fuel entry

• Each row in the BDN Bio Fuel table can be deleted using the trash icon at the end of the row. Deleting a parent Blend row also removes its components.
• To correct a quantity or component selection, delete the parent row and re-enter via + Add Bio Fuel. There is no direct in-line edit — the dialog flow is the only path that keeps the parent/component link consistent.

Documents & Remarks

Field	Meaning
Letter of Protest	Yes / No — select Yes if any LOP was issued during the bunkering.
Cert of Quality Rec’d	Yes / No.
Remarks	Any discrepancies, delays, or quality observations.
