Thanks for your valuable contribution in sharing knowledge for the advancement of the shipping industry in the area of surveying.The Corrected Sounding means below is the sounding after correcting with vessels trim and list.Temperature of Oil on Tanks, Oil Density 15C, Table ASTM 54B (VCF) and Table ASTM 56 (WCF).
Tank Volume at Sounding 3.20 M 157.20 Cubic Meter, at Sounding 3.30 M 163.60 Cubic Meter. ASTM Table 54B T 56 (WCF): Density 15C 0.9903 0.9892 (Quick formula with reducing factor for WCF is Density 15C 0.0011 0.9903 0.0011 0.9892). So, The Quantity in MT is 161.68 x 0.9870 x 0.9892 157.85 MT. Trim is stated the different between fore and aft draft condition, while List for inclination to port (left) or starboard (right). So, to make the surface flat, it need correction to calculate accurately. You should check the post in the Steps for Conducting Bunker Survey you will find the answer. Pls I need a work Example too on Procedure for calculating Bunker Survey. If so how can we do a calculationhandle for VNET situation. How can we get the correct VCF by only using calculationtable 54. Quick formula with reducing factor for WCF is Density 15C 0.0011 example: density 0.9903 0.0011. Your contribution is highly appreciated to all surveyors specially Beginners. ASTM Table 54B by Boriss Grahlovskis (freeware). Good luck. If your tank capacity is 50m x 25m x 10m 12,500 m3, you should find the the quantity in m3 at 1m ullage. As per above tank, you 1m ullage is 50m x 25m x 9m 11,250 m3. The 11,250 m3 is the maximum volume in m3 that required for your tank. Check the astm table for your cargo density and heating temperature. If use astm table 54b, when density 0.910 20c the factor is 0.9962. Then 11,250 m3 x 0.9662 11,207.25 m3 15c. To cope with this issue, you should calculate the final volume m3 after heating where: 11,250 m3 x 0.9886 11,121.75 m3 15c. Just find the ullage that point to 11,164.17 m3. Your cargo will be save at 1m ullage after heating. As you are working with the surveyor company, it would be better to learn directly from your company colleague. Bunker Survey Calculation Software How To Calculate BunkerI would like to know how to calculate bunker in tug boats with the BHP 2500 to 4000 BHP. I need your advice on the best certification I should go as regards Inspection Jobs. As per API MPMS Chapter 11.1 (ASTM D 1250-04 and IP 20004), Table 54B for your density 15C 0.9905 and fuel temp. C the true VCF is 0.9891.
