BUNKERING

Chief  engineer received a mail from company.In that mail,how much tonnes are taken at which port and which oil (H.F.O OR D.O) are mentioned.

 Chief engineer organized tool box meeting for bunkering. In this meeting duties are discussed with as Ass.4th engineer,which tank to be empty.Make sure bunker tank should be 90% of tank capacity.

On the day of bunkering first of all fill the bunker checklist.

Bunkering tank and overflow tank to be empty.

Then shut all the storage tank valve.

Stop the purifier.

H.F.O and D.O transfer pump.

Bunker barge  are arrived.

Bunker barge should be secured with ship.

Bunker survey will check all the sounding in E.C.R.It should be note.

And heel,list and temperature are noted.

Bunker survey and 4th engineer are do the same procedure on barge also.especially temperature and density should be noted.

Make the proper communication with bunker barge and emergency sign should be discussed.

Bunker connection is made with bunker manifold and  in between the sampling flange is fitted to  to collect sampling fuel.

Put the tray below the manifold connection and scrubber plug are pluged and SOPEP KIT should be placed.

Check and line up the connection of filling tank.

Slowly start the bunkering.

Now the pressure and temperature should be checked.

check the filling tank sounding.If there is no problem then slowly increase the problem then slowly increase the speed of bunkering.

In case we filling the 2nd tank.

First we will filling tank nearly 90% of capacity.

Reduce the speed of bunkering and open the 2nd valve.

Slowly close the 1st tank valve. 

Complete the bunkering with 2 or 3 air kick.

Finally the bunker survey check all the tank sounding,list,trim and temperature.

Disconnect the bunker manifolds.

Sampling should be collected in four sample bottle. 1. Marpol sample 2.ship sample 3.lab  sample 4.Bunker barge

Fill the bunker checklist with the sigh for barge officer.

B.D.N (bunker delivery notice) and M.S.D.S(material safities and data sheet) are received.

Oil record book should be filled and signed by 4th engineer and chief engineer.

Ideal properties of a Marine Refrigerant


Low Boiling Point (for easy system start).

High Enthalpy of vaporization ( to gain more heat from the evaporator).

Low Condensing Pressure (easy condensing).

Less specific volume in vapor state (to accommodate less space in line).

High Critical Temp (temperature above which vapor cannot be condensed).

Non Corrosive (system loving)

Non Solvent (to oil and impurities)

Non Miscible (to lub oil (possible to a certain extent)).

Non Flammable (for obvious reasons).

Non Explosive (Obviously).

Non Toxic

Easy Leak Detection (by odor or color).

Cheap and Easily available.

Environment Friendly.
