Pre-delivery Fuel Oil Documentation The purpose of the pre-delivery document is to record agreement on the operational details of the transfer and to ensure safe transfer of the product. This document originates from the seller’s representative and states the grade or grades with the nominated quantity. Ideally the grades will be expressed by reference to ISO 8217, which defines viscosity for residual fuel oil grades at 50°C. Distillate grades, instead of being referenced as DMA or DMB may be referred to as marine gas oil or marine diesel. Having established what is to be transferred, agreement has to be reached on the pumping rate acceptable to the receiving vessel to ensure safe transfer. The next aspect to be considered is witnessing of tanks by sounding or ullage and the approach to this is detailed later in this section. Agreement should be reached on the witnessing of a representative sample and this again is detailed later. The spill prevention transfer procedure must also be discussed and agreed. The key to this is communication and a checklist can be useful to ensure no points are missed
Bunker Delivery Note (BDN) The purpose of the Bunker Delivery Note (BDN or Bunker Delivery Receipt, BDR) is to record what has been transferred. MARPOL Annex VI requires the following details to be included: Name and IMO Number of receiving ship Port Date of commencement of delivery Name, address, and telephone number of marine fuel oil supplier Product name(s) Quantity in metric tons Density at 15oC, kg/m3 Sulphur content (%m/m) In addition the BDN will include: Temperature of product delivered Sample seal numbers The MARPOL BDN must also have a signed declaration by the fuel oil supplier’s representative that the fuel oil is a blend of hydrocarbons derived from petroleum refining that: Meets applicable sulphur limits Is free from inorganic acid Does not include any added substance or chemical waste that: Jeopardizes the safety of ships or adversely affects the performance of the machinery, Is harmful to personnel, or Contributes overall to additional air pollution Alternatively, in the case that the fuel oil is derived by methods other than petroleum refining, as well as meeting the above conditions it must not: Cause an engine to exceed the applicable NOx emission limit Care should be taken before g the BDN. For example, the bunkers should not be signed for in weight form, only for volume at observed temperature. The actual weight can only be calculated after a representative sample of the delivery has been tested for density. MARPOL Annex VI requires the BDN to be retained for at least 3 years from the date of issue. Letter of Protest (should anything go wrong) Should there be any dispute in the quantity of bunkers delivered, the purchaser or his representative should issue a letter of protest, which is properly signed and stamped by both parties. An example of such a letter is shown below. The barge or fuel oil supplier as well as the ship owner or engine operator can use the letter of protest system. Bunkering Check List Bunkering is often carried out when the engineering staff are under pressure in both time and manpower. Key checks are often missed and only come to light when it is too late. A few relevant points are detailed below: The purchaser should obtain specification acceptance from the supplier Purchaser needs to advise ship’s staff what grade of fuel will be delivered and how transferred Fuels from different deliveries should be segregated as far as practical All receiving tanks need to be gauged prior to taking fuel
Don’t sign any documentation unless you have witnessed the actual event Always take up witness offers made by the supplier If the origin and method by which a supplier’s sample was obtained is unknown then sign for it adding the words “for receipt only - source unknown” Wherever possible always take fuel samples using a continuous drip method throughout the bunkering at the point of delivery on the receiving ship i.e. as close as practical to the hose connection At least four-five samples will be required for each barge/delivery/fuel grade: a. The official MARPOL sample which the Port State Control Officer (PSCO) may be required to be analysed. Note the MARPOL sample must be a minimum of 400ml and be retained for at least 12 months. b. The vessel’s own retained sample c. A sample for laboratory analysis d. A sample for onboard analysis e. A sample for the supplier f. Note further samples may need to be provided for any retained bunker surveyors Sign the BDN for volume only, if necessary adding the words “for volume only - weight to be determined after density tests” Ensure good records are kept throughout the bunkering Keep accurate engine logs in the event of any subsequent problems Keep bunkering fuel samples for at least 12 months Use on-site tests to check all fuel on delivery for Viscosity, Density, Water, Stability, Pour Point and Salt (if water present) Use a laboratory to check results in the event of any discrepancies being indicated by on-site test equipment. The master or crew should document any instance of the bunker fuel delivery note or representative sample not being in compliance with the relevant regulations It is also recommended that if laboratory analysis shows sulphur levels to be outside of regulatory limits the vessel’s flag istration, the bunker port istration and fuel supplier are notified -----------------------------------------------------------------------------------------------------------------------------------------------------BUNKER delivery note Clause 18 of MARPOL annex VI requires that all fuel oil taken by a ship must be accompanied by a bunker delivery note. The form of the bunker delivery note is described in appendix V to annex VI. Bunker delivery note checklist Name and IMO number of receiving ship. Port. Date of commencement of delivery. Name, address and telephone number of the supplier. Product names. Quantity (t). Density at 15°C ( test method ISO 3675). Sulphur content percentage (test method ISO 8754). Declaration signed and certified by the fuel oil supplier’s representative that the fuel oil supplied conforms with MARPOL annex VI regulations . The bunker delivery note should be kept on board the ship in such a place as to be readily available for inspection at all reasonable times. It should be retained for a period of three years after the fuel has been delivered on board. Clause 18 of MARPOL annex VI also requires that the bunker delivery note must be accompanied by a representative sample of fuel oil sealed and signed by the supplier. The bunker delivery note is signed by the bunker barge master and the chief engineer or master of the ship receiving fuel oil. It is usually stamped with the official stamp of the ship and/or barge. Because the chief engineer does not have access to an accurate, laboratory-determined fuel density figure (this will be ascertained by laboratory analysis of the bunker sample), the bunker delivery note should only be completed using figures for the volume of fuel oil loaded. Indeed, the engineer should only sign any documentation stating ‘for volume at observed temperature only’ as there can be no certainty of any weight figures for the fuel loaded. Non-compliant ports If fuel oil is taken in a state that has not ratified MARPOL annex VI, the supplier is not required to issue a bunker delivery note that complies with MARPOL requirements. However, the ship may require suitable documentation to satisfy port state control officers at subsequent ports.The recommended procedure when such a situation arises is that the master should notify the port
state authorities at the port where the fuel oil was taken, and the ship’s flag state, and keep a copy of such notification on board to produce to officials at subsequent port state inspections. A draft letter of notification is given in Appendix II of this guide. A bunker delivery note and representative fuel sample should be obtained whenever possible
