Guideline for ship -Procedures for taking and storing the Fuel Oil Samples
FO sampling method (taken by ship):
The Chief Engineer shall extract proper volume of samples representing the qualities of the fuel oil delivered in the following items. The sampling method shall be continuous dripping at the shore connection on board the vessel, in general. Regarding each sample bottle, the sample label shall be filled necessary items and signed by the Chief Engineer and the suppliers representative and the samples shall be sealed.
If the FO supplier refuses to sign the samples extracted, the Chief Engineer shall inform the company Technical Superintendent of the fact immediately.
The samples should be kept in a safe storage location, outside the ships accommodation.
(a) Sample bottle required by MARPOL :
One bottle of sample (Approx. 1 liter/bottle) shall be extracted from the FO collected by the abovementioned continuous dripping and shall be retained with the seal intact under the ships control until the fuel oil is substantially consumed, but in any case for a period of not less than 12 months from the time of delivery. MARPOL sample and Bunker Delivery Note shall be kept on board properly for Port State Control etc.
(b) Retained SAMPLE :
Two bottles of sample (Approx. 1 liter/bottle) shall be extracted from the FO collected by the abovementioned continuous dripping, and one bottle shall be delivered to the supplier and the other shall be kept on board.
The sample for the vessel shall be kept on board for six months with the seal intact. It shall be taken ashore on the Company's instruction, if necessary.
Note: It is a commercially accepted practice to understand that the newly loaded oil is affected by the remained oil in the ship's tank to be different in qualities, when it is put into the ship's tank. (Even if the new oil is put in an empty tank, it is assumed that the new oil may be affected by dead oil or remained oily components in piping.)
Therefore, in the case of an engine trouble caused by fuel oil, the only evidential object that represents the qualities of the loaded fuel oil is such retained samples extracted by the above method
(c) SAMPLE for Analysis (DNV, VISWALAB, etc) :
In case, FO sample is be analyzed by third party, C/E shall collect sample in line with the Sampling Procedure instructed from the third party then send it to the designated address. The technical superintendent in charge shall inform the vessel of the result of analysis, putting necessary comment on it.
(d)One sample for the bunker surveyor, if engaged
Retained Sample (by supplier)
Chief Engineer shall receive one bottle of retained sample from the FO supplier and keep it on board in the following manner.
(a) If the FO supplier refuses to submit the retained sample, the Chief Engineer shall inform the Chief Technical Superintendent of the fact immediately through the Captain.
(b) When the retained sample from the supplier is collected other than continuous dripping (for example, dipping up from the barge tank or collection from a sample cock and the like during a short period of time), this fact shall be noted on the samples with signature by both the parties. Chief Engineer shall report of the matter without delay in this case as well.
(c) The retained sample submitted by Bunker supplier shall be kept intact with the seal onboard for a period of 6 months from the time of delivery.
