If you are specifically looking for the (Interpretation 1), I can provide the specific mathematical derivation used in their papers to calculate fuel quality.
FOBAS is a service provided by Lloyd's Register that tests marine fuel oils. A "FOBAS calculator" typically refers to the calculations used to determine fuel quality parameters, specifically the Carbon Residue (MCR) or Calculated Carbon Aromaticity Index (CCAI) .
Using a FOBAS calculator typically involves the following steps: fobas calculator
The operator must enter the following parameters into the calculator: Current sulfur content in use (e.g., 2.50%).
: The total volume of the fuel circulation system, including pipes, mixing tanks, and heaters. If you are specifically looking for the (Interpretation
The FOBAS Calculator is a specialized software tool, usually provided in Microsoft Excel format, that simulates the linear blending process of fuels within the ship’s service system. It is not merely a timer; it is a simulation tool that uses ship-specific data to determine when to start the fuel switchover process, factoring in: Sulphur content of the fuel currently in use. Sulphur content of the target low-sulphur fuel.
The latest versions of the FOBAS calculator (e.g., version 6 or 8) are simplified to allow for rapid calculations by the engine crew. 1. Data Input Using a FOBAS calculator typically involves the following
As the maritime sector continues to prioritize decarbonization and emission reduction, tools like the FOBAS Fuel Changeover Calculator are indispensable. By bridging the gap between complex chemical blending and real-world engine room operations, it ensures that global shipping remains compliant with international law while protecting the mechanical longevity of the world's fleet.

Since "FOBAS" is not a widely recognized standard acronym in general mathematics or computer science, it is most likely a typo or a specific term from a niche industry. Below are the three most likely interpretations of what you might be looking for, along with a summary of what a paper on that topic would cover.
A FOBAS calculator is a valuable tool for:
