Petroleum Calculation Series: Definition

  Ambient Temperature: The temperature of the surrounding medium such as the atmosphere. API: American Petroleum Institute. API Gravity (Relative Density): A means used by the petroleum industry to express the density of petroleum liquids. API gravity is measured by a hydrometer instrument having a scale graduated in degrees API.  The relation between API gravity and relative density (formerly called specific gravity) is: API...

Draft Survey Software

I have tried to complete the sevensurveyor project and developed one simple software for draft survey calculation named 7S DraftSurvey. This software is made for automatic draft survey calculation such as; quartermean draft, trim, fore and aft draft corrections, Displacement, TPC, LCF, MTC, 1st & 2nd trim corrections, density correction and deductibles. The software could be used to determine the total cargo loading/unloading on...

Draft Survey: The Accuracy and Factors Effecting

Sometimes the accuracy of Draft Survey is a big question, especially when the cargo loaded or discharged from the vessel shown extremely different weight with the references Weight Scale or Counter Weight. Unfortunately, the parties concerns would be doubt on to the weight resulted by Draft Survey, as they have been relying upon the mentioned scales for many years. Draught Survey UN ECE: Code of Uniform Standards and Procedures UN ECE...

Bunker Survey Calculation

The bunker calculation is simple and needs the following: – Tank Sounding data and Tank Capacity Table. The Corrected Sounding means below is the sounding after correcting with vessel’s trim and list. – Temperature of Oil on Tanks, – Oil Density @15*C, – Table ASTM 54B (VCF) and Table ASTM 56 (WCF). Now we could go with sample of 1 tank to test the calculation. ** Question : FO Tank No. 1 Center, Corrected...
