These general requirements are already part of the ISO 13739 but it is essential that each of our individual surveyor shall duly follow them so as BQS are done with transparency, efficiency, professionalism and independently at following stages.

Before Bunkering

  • Introduce yourself clear as a surveyor, representative of vessel’s principals for Bunker Survey.
  • Conduct the survey as per concordance with ISO 13739/2009 “Procedures for transfer of bunkers to vessels”.
  • Request the barge Cargo Officer not to strip the tanks and to blow the line only after measurements.
  • Go to measure physically all nominated & non-nominated tanks with C/E or his assistant to witness the gauging.
  • The surveyor must go onboard the barge with his own (certified by a competent and contactable authority) hand tape and thermometer.
  • In presence of C/E and Bunker barge Cargo officer; all tanks are measured by HAND TAPE, including ALL non-nominated tanks, settling, service, overflow and sludge tanks. At least three barge tanks are measured for the determination of the supplied fuel temperature. Levels and temperatures were taken to be recorded on the Bunker barge sounding ticket. Remote gauging and indications to be recorded, as an additional reference.
  • Ask the Ship’s Officers to provide the original of the barge calibration tables with a certified stamp from an approved and recognized body.
  • Hand tape measurement and printed form from barge have to be signed by all parties concerned.

During Bunkering

  • We closely monitor the smooth undergoing of the bunkering procedure.
  • We observe carefully the bunker hose for any excessive vibrations and u201cair in liquidu201d specific sounds.
  • We make checks at random intervals on the bunkering barge, verify the levels in the tanks already declared as empty/stripped and verify carefully the bunker piping for any derivation.

After Bunkering

  • We request to C/E a printed form from automatic ships measurement after bunkering, in order to verify if expected volume is approximately received.
  • We take temperature of fuel received immediately after the bunkering (especially in cold waters).
  • When barge Cargo Officer finish the delivery ensure he announces it to the PIC at the bunker station and stop the delivery WITHOUT BLOWING the lines until the measurements are done and the final figures ascertained (again, this must be established and
    agreed upon from the beginning)
  • Volume at observed temperature has to be jointly measured by surveyor and C/E.
  • Blowing must be done in only one tank of the vessel for easy gauging.
  • Request the Barge’s Cargo Officer for a printed form to be signed by parties attending: Barge Captain – C/E – Surveyor.
  • We measure the receiving tanks from seagoing vessel. Ullage can be taken, when good reference to reference height as initial measured (tank height).
  • We ask the barge Cargo Officer to open the hatch to visually check the content of each tank in case of suspicion of fraud attempt.
  • Ensure the CE to record on the BDN “For volumes at observed temperatures only, final quantity subject to lab tested density”
  • Advise the CE not to sign any paper if the barge Cargo Officer stops pumping before the final quantity is reached.
  • ln case of too much discrepancy (more than 0,5%), a LOP – Letter Of Protest has to be issued. in case of any doubts:
    Re-gauge all barge tanks (nominated & non-nominated tanks).
    Re-gauge all seagoing vessels’ tanks (nominated & non-nominated tanks), including setting tank, daily service tank and overflow tank.


  • Pay special attention to abnormal noises and vibration of bunker hose, and make a note in SOF of the possibility of air mixed in the fuel.
  • Sampling during bunkering:
  • MARPOL Annex VI recommends samples to be taken to the closest point of the vessel manifold.
  • We ALWAYS insist in to act with an in-line continuous drip sampler at the ship’s manifold.
  • ln case of dispute, barge sample is final & binding according to delivery conditions of Supplier.
  • If the barge Cargo Officer accepts one set of samples at the vessel manifold, agree with all parties how many samples need to be taken for each barge and grade.
  • As the barge sample remains the Official sample, the surveyor is requested to witness the sampling process on the barge side with a ship’s representative.
  • The way of sampling onboard the barge must be clearly recorded on the survey report. (any abnormality such as spot sampling, poor sampling and no correct in-line continuous drip sampler method)
  • Seal the sampling cubitainer to avoid any tampering throughout the bunkering process.
  • ln case of LSFO / HSFO deliveries, start with LSFO first.
  • LSFO sampling must starts after 5 minutes flush in order to clean the line.
  • Surveyor and C/E have to be present at the distribution of samples.
  • Records seal numbers and write these numbers on “Sample witnessing report”.
  • Sign only the validated sample, witnessed by the surveyor as principal’s representative.

Quantity Disputes

Quantity of the barge alongside is binding for delivered quantity.
C/E is the one only who gives permission that barge leaves alongside. ln case of severe discrepancies, C/E must call an ORDERER bunker desk and ask for P&I assistance with the assistance of the surveyor.
