This software is designed for Marine Bunker Surveyors to minimize time in bunker quantification following API-MPMS guidelines. It also contains some other conversion tools which are really important to calculate the fuel characteristics like Shell CCAI, BP CII, Net and Gross Specific Energy, Injection, Temperature based on measured viscosity, density conversion tools and much more.

“TankerCalc”
For Bunker Surveyors

2. Bunker Quantity Determination Software “TankerCalc”
This is the software designed to automate entire bunker calculation process without
compromising with any standard. All of the petroleum measurement tables required to
work with Density, API Gravity or Specific Gravity are embedded in this software. This is light
weight and can be used without installation in any windows based system.
This is applicable for, Crude Oils, Gasolenes, Transition Zone, Jet Fuels, Fuel Oils and Lubricants
The main feature of this software is interactive conversion capabilities. With a single click one
can switch from one measurement standard (say, Density based measurement to APIG
based measurement) to another standard without changing the existing values. The
accuracy of the calculation is tested by comparing with DNVPS software “Bunker Master
2.0” and with Shell’s “BunkerCalc”. This software can be used universally to calculate the
actual fuel quantity. Additionally this software contains energy calculation tools, density
conversion tools, VCF calculation tools, WCF calculation tools, MT calculation tools and
much more.
The software is featured with OFF HIRE BUNKER SURVEY, BUNKER ROB SURVEY, ULLAGE
REPORT GENERATION, BUNKER STEM SURVEY and much more

23. Bunker Quantity Determination Software “Excel Based”
This is an excel based software designed to automate entire bunker calculation process without compromising with any
standard. All of the petroleum measurement tables are embedded in this software. There’s no need to carry the
ASTM petroleum measurement tables (ASTM 53B, 54B and 56D). The accuracy of the calculation is also tested
comparing with DNVPS software “Bunker Master 2.0” and with Shell’s “BunkerCalc”. This software can be used
universally to calculate the actual fuel quantity in any tanker.
