(HFO)
DM = Distillate Fuels (MGO / MDO)

Blends = Mix of RM

General definition
MGO = Marine Gas Oil
MDO = Marine Diesel Oil
HFO = Heavy Fuel Oil
FO = Fuel Oil

Sulphur limits
HS (high sulphur) 0,5 % < 3,5 % sulphur
VLS (very low sulphur) 0,1 % < 0,5 % sulphur
ULS (ultra low sulphur) < 0,1 % sulphur

In future you will receive many different types of fuel!

Elements

Carbon — 83 to 85%
Hydrogen — 10 to 14%
Nitrogen —

Crude oil is a mixture of organic molecules, characterized by paraffins, naphthenes, aromatics

The elements are stored in different type of molecules

a mixture of hydrocarbons chains
The main types of molecules are:

CH4, Methan (LNG)

C8H18, Super Gasoline

C16H34, Cetan (Diesel)

Residues products

Destillate products examples

Aromatics and Naphthenes
All remains from cracking
Long paraffin chains with high carbon
Asphaltene and Resin

Destillate

Residual

S Fuel
Density vs Viskosity
Density [kg/m3]
Viscosity [cst]
800 850 900 950 1000
Cetan C16H34
Asphaltene
Docosan C22H46
Paraffins
Benzol
Naphthalin
Aromaten
Asphaltene

S Fuel

S fuel
Class A: More Aromatics Fuels
A blend with high

Class B: More Paraffinic Fuels
A blend with high content of long paraffinic chains
Low density and higher viscosity  Middle CCAI
Stable fuel

Class AB: Straight Run Fuels (also called hybrid fuels)
A the residue product of the first distillation (Atmospheric)
The used crude oil has very low sulphur
Medium density and medium viscosity
Quite stable fuel

Fuels with high density and low viscosity most unstable fuel!

Most important document is the “Fuel Management Plan”

Fuel Management Plan

qualities
Heating to be done carefully
Segregation of Sulphur (PSC detention)
Mixing
Some fuels

Treatment
Heating in storage tank to be done carefully
Settling tank temperature ????  to be confirmed from suppliers
Purifier temperature  to be confirmed from suppliers
Service tank temperature

Change over from 0.5% S fuel to next 0.5% S fuel
Settling tank must be fully empty
Service tank as much as possible empty (in case of doubt change over to MGO and drain service tank)

3 Samples

Usually 4 Samples are taken on barge:
One for the vessel (handed over to vessel)
One for Marpol (handed over to vessel)
Two for the Barge

?

(BDN)
Only sample/ seal numbers from BDN are official in case

Always watch sampling on bunker barge!

Claim to supplier

Letter of Protest

Call Operator

After confirmation stop bunkering

If sampling will be
done on barge

does not agree to take official BDN samples on vessel

The samples at barge manifold are not taken correctly
Contact your operator/ stop bunkering????
Letter of protest
In any case samples to be taken on vessel manifold as well
Don’t sign the BDN with remark or written approval by operator

No drip sampler
Wrong adjustment of valve
Wrong position of sampling

Always check carefully the BDN before signature!!

MARPOL
As per MARPOL 73/78 Annex VI, Regulation 18, Chapter 8.1

Due to the „should“ we can not request to take samples at the vessel manifold

Bunker flange with adjustment valve
End of bunker line
Cubic container to be sealed water tight
Correct adjustment of the adjustment valve

MARPOL

The following documentations has to be done
- Bunker Checklist Bunker

To be noted
- F23, BDN, Pictures, LOP to be send to your inspection group
- request witness for sampling and vessel samples to be signed by barge
- If BDN is not correct and charterer has instructed you to sign, please sign with remarks:
+ “for receipt only”
+ “LOP has been issued”

the supplier if the official samples can be taken at

the supplier if the official samples can be taken at

Note: In any case also samples at vessels manifold to be taken and send to laboratory.

be found in circular T57

To be signed by the bunker
