  "heading": "Method B: Bunker fuel tank monitoring on board",
  "text": "(1) In this Schedule, a reference to method B is to be construed in accordance with this paragraph.\n(2) This method is based on fuel tank readings for all fuel tanks on board. The tank readings must occur daily when the ship is at sea and each time the ship is bunkering or de-bunkering.\n(3) The cumulative variations of the fuel tank level between two readings constitute the fuel consumed over the period.\n(4) The period means the time between two port calls or time within a port. For the fuel used during a period, the fuel type and the sulphur content need to be specified.\n(5) Fuel tank readings must be carried out by appropriate methods such as automated systems, soundings and dip tapes. The method for tank sounding and uncertainty associated must be specified in the emissions monitoring plan.\n(6) Where the amount of fuel uplift or the amount of fuel remaining in the tanks is determined in units of volume, expressed in cubic meters, the maritime operator must convert that amount from volume to mass by using actual density values.\n(7) For the purpose of sub-paragraph (6), the maritime operator must determine the actual density by using one of the following—\n(a) on-board measurement systems;\n(b) the density measured by the fuel supplier at fuel uplift and recorded on the fuel invoice or BDN;\n(c) the density measured in a test analysis conducted in a fuel test laboratory, accredited in accordance with EN ISO/IEC 17025 as updated from time to time, where available.\n(8) The actual density must be expressed in kg/cubic meter and determined for the applicable temperature for a specific measurement. In cases for which actual density values are not available, a standard density factor for the relevant fuel type must be applied.",
