We could records the tank gauging for determining the quantity, the temperature at the thermometer available on each tank, and the Oil Density from the Engine Log Book. The Service and Settling Tanks are not accessible due to the oil on that tanks were in heating condition at the high temperature. Taken Oil sample, check temperature and oil density, for the accessible tank only. Check the Ship’s Draft Marks to get the Ship Trim for Trim correction, and check the ship Inclination or Listing for List Correction, that is required to calculate the Tank Quantity Table. Attached the sounding Tape with Oil Paste to make easy and clear to show of oil level (recommended for Light Oil). Sounding each Oil Tank and records the level of Oil on the tank. In case we used Ship’s Sounding Tape, please checking the tape.
Checking the accuracy of the Sounding Tape, it is recommended to use your own Sounding Tape. Records the quantity of bunker onboard when the ship arrives at Port (arrival Condition) as per Engine Log Book. Record the Last Bunker Report, Time and Place of last Bunker supplied, includes the Oil density. The both methods will point to the same result. Sounding Pipe) to the liquid surface (typically applied for heavy liquid). Ullage means to determine the level of liquid of tank by measured the empty space from top of the Tank (the mouth of Sounding is determined the level of liquid tank from the bottom of the tank to the liquid surface (typically applied for light liquid). Steps for Conducting Bunker Survey Identify and records the number and Depth of Tank, Reference Height, and Measuring Method recommended to use (Ullage or Sounding) for each Oil Tank. Survey Tools required for Bunker Surveyor Notes Book, Sounding Tape, Thermometer, Density Meter for Oil (0.750 -1.000), Oil and Water Paste, Petroleum ASTM Table 54B (for Product Oil) and Table 56, Google and Glove, Flashlight, Sampling Can, Bottle or Can for Sampling (if required taken samples).

In this post limits to how to conduct the Bunker Survey on the ship tanks only. This job is associated with Ship’s Chief Engineer, the Person who responsible for bunker onboard. This survey is produced the report that states the amount of bunker, usually Fuel Oil (FO) and Diesel Oil (DO), and sometimes Lubricating Oil (LO) is included.Ĭommonly this is done prior to and after a time charter period than mentions as On Hire Bunker (prior) and Off Hire Bunker (after), the Bunker Survey is required to check the amount Bunker transferred or supplied onto the Ship’s Tanks. How to Conduct Bunker Survey What is Bunker Survey? Survey? The survey is carried out to measure and ascertain the quantity of Bunker onboard at the specific time.
