Viswa Lab Fuel Oil Analysis

Testing bunker fuels is a necessity and not a luxury. Every well-run shipping company should test fuels routinely. This is as important as insuring your car against accidents. Even though, fuel related machinery problems are caused by only a small percentage of all the fuels supplied, the importance of regular fuel testing should not be underestimated. It is not only about fuel related problems but also about a more serious issue, namely the safety of lives onboard, where there can be no compromise.

Yes, there was a time when there were no residual fuels. All heavy fuel oils were straight run products. Today, all kinds of secondary refining processes are employed to extract the maximum quantity of lighter fractions, which provide greater price benefit to the refinery operator. The consequence of this is a residual fuel that is continuously deteriorating in quality. This is not the only problem.

New regulations have been enforced to cut down the NOX & SOX emissions and even CO2emissions. These new regulations compel the refineries to make changes in their refining processes, which result in residual fuels that cause problems that are even more serious to the fuel user.

Fuel oil analysis protects ship operators by forewarning them about fuel-related troubles, and independently documents' fuel quality for insurance purposes. Moreover, this aspect is checked during oil major vetting inspections.

Furthermore participation in a fuel testing program is proof that operators in marine industry is following industry's best practices advocated by the Tanker Manager Self-assessment (TMSA) programme.

Fuel Oil Analysis comprises of a series of tests to determine the quality of the marine fuel supplied. Viswa Lab tests samples by both the ISO 8217:2005 and ISO 8217:2010 standards.

The analyses conducted determine the characteristics of the fuel. More comprehensive testing, in addition to the tests recommended by the standard, may be required based on the initial findings and any problems faced by the vessel. Please refer to our section on Forensic Analysis of Problem Fuels for further information.

Important notice for sampling

In order to obtain a representative sample of the fuel delivered to the ship, the sample has to be drawn continuously throughout the entire bunkering process. To achieve this use of the continuous drip line sampler together with clean cubitainers is recommended. The line sampler should be sealed to prevent tampering during the sampling operation. Please note that the use of a continuous drip or auto-sampler is required by resolution MEPC.182(59) "Guidelines for the Sampling of Fuel Oil for Determination of Compliance with the revised Annex VI of MARPOL". It should be noted that bunker sampling practices may vary from supplier to supplier, country to country and even port to port. In most ports, other than Singapore and Gibraltar who have their Code of Practice for Bunkering, the legal and binding commercial samples according to the supplier’s Terms and Conditions are usually the samples taken by the supplier and the sampling point of these commercial samples may not be the vessel manifold. It is therefore important to review both local requirements as well as the supplier’s Terms and Conditions/Charter Party agreement to assess where the legal and binding commercial samples as per the supplier’s Terms and Conditions/Charter party agreement are to be taken during bunkering operations. If these samples are not being taken at the ship’s manifold, it is important to have a ship representative/surveyor witness the sampling and sealing of supplier’s commercial samples even though another set of samples are being drawn from the ship’s manifold by the vessel crew. It is also recommended tocounter-seal the supplier’s commercial samples but only in case the sampling has been witnessed and the samples are considered to be representative.

Overview of Samples

The diagram below describes the purpose of each of the fuel oil samples to be taken routinely under the Fuel Quality Testing (FQT) and Fuel System Check (FSC) programme, as well as the associated labels accompanying these samples.

Sample to laboratory This sample should be sent immediately to a VISWA laboratory for fuel quality testing. Ship’s retained sample This sample sealed with a security seal should be retained on board. In the event of a dispute, the sample may be required to be sent to a laboratory for testing.

Sample to supplier This sample should be given to the supplier. If the supplier declines or discards the sample, make sure that this is recorded in the ship's log. Please note that each sample should be duly filled (i.e. “FILL TO THIS LINE”), sealed and the respective labels.

Line sampler

Obtaining a representative sample from each bunkering is an essential part of the fuel management procedure on board the vessel. It requires the use of appropriate equipment which makes it possible to take a sample that is representative and acceptable for all parties involved. The reliability of test results from fuel quality analysis and fuel density used in calculations for quantity measurements are dependent on correct sampling procedures being followed. Please ensure that the vessel is equipped with a MARPOL Annex VI compliant line sampler sampling device installed at the point of Custody Transfer, i.e. at the ship's bunker manifold. If your vessel is not fitted with a proper sampling device, it may not be possible to take a representative sample as required by MARPOL 73/78 Annex VI. The Line Sampler consists of a sampling probe assembly complete with needle valve, security cap, Teflon cap and metal cap. Sampling is carried out by the continuous drip method throughout the duration of the bunkering. Installation is extremely simple using the two fully threaded long bolts provided to secure the sampler to the bunker manifold. The diameter of these two fully threaded long bolts is slightly smaller such that the sampler can be “permanently” fitted to the outer flange of the bunkering manifold. The remainder of the provided bolts is half threaded and are long enough to penetrate the bunkering manifold, the sampler as well as the bunker hose flange; hence there is no need to remove or install the sampler at each bunkering. The needle valve is used to control the rate at which a continuous drip sample can be drawn. It also serves as a stop valve for the sampling. The anti-tamper security cap prevents unauthorized changes in the adjustment of the drip rate during sampling. The sample is collected in a disposable 10-litre or 5-litre cubitainer, which is screwed onto the sampler and threaded with the seal. The cubitainers watertight system prevents contamination from rainwater, dust and cargo such as bauxite, grain etc. The Line sampler has proven itself as a tamper-evident, reliable and cost effective sampling device for obtaining representative fuel samples.

Sampling Procedure for Bunkering Safety Considera_ons during Sampling The following safety precautions should be taken during any sampling:

Protective equipment should be worn by personnel involved in the sampling

H2S detection device should be worn by personnel involved in the sampling

Oil spill prevention procedures should be adhered to

Oil spill containment equipment should be available at the bunker manifold

Regulations regarding entry to and equipment used in hazardous areas should be strictly observed

During the bunkering process check for leakage from the bunker hose connections and the sampler

Do not attempt to remove the needle valve during the bunkering process

Smoking and naked lights should be prohibited in the vicinity of potential oil vapour sources Note: For each bunkering the line sampler has to be clean and in good working order. When different fuel grades or products are required to be sampled using the same sampling device, the ship’s staff should take precautions to ensure the manifold line is flushed of previous product to avoid cross contamination so that the samples taken are representative of each delivery.

Installation and adjusting the line sampler Carefully connect the line sampler to the bunker manifold, keeping the ARROW mark on top and following the bunker flow direction. Use the two fully threaded bolts and new gasket to secure the sampler to the bunker manifold through the two threaded holes in the flange. Make sure the drain holes of the sampling probe are not obstructed. Connect the bunker hose using the new gasket and half threaded bolts. Tighten the bolts as per the torque requirement and bolt size. Remove the safety cap from the drain probe and attach a new and clean cubitainer to the probe. A tell-tale hole is provided on the metal cap of the cubitainer connector. This also acts as an air vent. Make sure it is not blocked as otherwise the cubitainer may be filled with air during the initial start of bunkering.

Align the sealing hole on the cubitainer with the line sampler security cap. Insert the cord of the security seal and pull hard to make sure it is taut. A needle valve is located on the lower end of the drip sampler. This needle valve is used to adjust the rate of drip according to the bunker flow rate.

Commence pumping of bunker and adjust the needle valve of the line sampler until achieving a drip rate that will give a slow continuous drip lasting throughout the whole bunkering period. Ensure that the drip rate is set to give sufficient volume of fuel sample in the cubitainer by the end of the bunkering. The barge master and vessel's chief engineer should be invited to witness the adjusted drip-rate and sealing process, which is as follows: i. Cover the adjustment screw of the needle valve with the security cap. Wrap the free-end chain of the security cap around the stem of the needle valve. ii. Insert the cord of the security seal into its locking device and pull hard to make sure that it is taut. iii Record the security seal number and get both the barge master and vessel's chief engineer initials on the document. Any required adjustment on the flow rate of the needle valve requiring breaking of the security seal should be witnessed by the barge master and by the vessel's Chief Engineer and replaced afterwards with a new seal.

Request To Witness Sampling Form Invite the supplier's representative to witness the sampling procedures. Complete a ‘Request to Witness Sampling' form and ensure that it is signed by both parties. Give the top copy to the supplier's representative. The blue copy is for the ship’s files. If the supplier declines to attend the witnessing of sampling, you must note this in the ship's log-book. Such a record can serve as contemporaneous evidence should a fuel quality dispute later arise. Please ensure that full details such as barge, cargo officer, supplier, _me, date and circumstances are recorded.

Ship's Retained Sample It is important to retain one bottle of sample onboard in a secure location, because in most cases this may be the only sample left which represents the fuel delivered to the ship. Note: If offered a sample by the supplier representative and if taking this sample has not been witnessed, please use the rubber stamp provided in the kit to indicate “For Receipt Only, Source Unknown” on the sample bottle.

MARPOL Annex VI Sample MARPOL Annex VI refers to MEPC.182(59) “Guidelines for the Sampling of Fuel Oil for Determination of Compliance with the revised Annex VI of MARPOL” which states that a sample of the fuel delivered to the ship should be obtained at the receiving ship’s inlet bunker manifold and should be drawn continuously throughout the bunker delivery period. This MARPOL sample has to be retained under the ship’s 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. It is the supplier's obligation to provide a representative MARPOL sample, continuously drawn throughout the entire bunkering process. The sample is to be sealed and signed by the supplier’s representative and the master or officer in charge of the bunker operation on completion of the bunkering operation. In the event that the supplier does not fulfill the obligation to provide a MARPOL sample or in case it is not taken as per the guidelines in MEPC.182(59) the following actions should be taken: - Inform the supplier about the fact that the sample is non-compliant, referring to MEPC.182(59), and propose to prepare the official MARPOL sample from the cubitainer as used for the three routine bunker samples taken at ship manifold. The sample has to be sealed and clearly marked as MARPOL sample. It is recommended that the seal number of the MARPOL samples is registered on the BDN for cross-reference. If this is accepted by the supplier a Notification is not necessary. - If the supplier does not accept to take the MARPOL sample from ship manifold, a Notification highlighting the non-compliance with MARPOL Annex VI requirements should be issued. The Notification is to be forwarded to the relevant Port State and the Ship’s Flag State. - In addition to the Notification and in the absence of a properly taken MARPOL sample provided by the supplier the crew may optionally prepare a SHIP's MARPOL sample from the cubitainer as used for the three routine bunker samples taken at the ship's manifold. This additional fourth sample should be sealed and clearly identified as SHIP's MARPOL sample on a white label and documented as such for retention on board. The suppliers' sample should be countersigned with the appropriate reservations e.g. “For receipt only-source unknown” (using the rubber stamp supplied in the sampling kit). - If there are technical reasons as to why a sample cannot be taken at the receiving ship's manifold (e.g. vacuum problems and/or extreme weather conditions), then such reasons should be recorded in the ship's log book and the sample taken elsewhere. For example at the barge manifold.
