Produce a variety of reports, including:



  • Ullage reports

  • Transfer (executive) summaries for both ship and client

  • Bunker survey reports

  • Notices of apparent discrepancy

  • VEF reports

  • Slop reports

  • Sampling reports

  • Pre-loading reports

  • Master's receipt of samples reports

  • Reference heights and raw measurements reports

  • OBQ and ROB reports

  • Time sheets

Essential Tools Included


Tools available in the app include:



  • Bottom Lines Calculator

  • Wedge Calculator

  • Pre Cargo Matrix for advice on required tank cleaning prior to loading the next cargo

Email and Transfer Reports


Reports can be emailed directly from the app as a PDF or JPG attachment and can also be transferred to a desktop computer for printing.

Customizable Standards


All reports can be generated using either SI Metric or Imperial standards, allowing for mixed units as per user requirements. For example, users can enter temperatures in degrees Celsius while producing an ullage report, but have the report printed using degrees Fahrenheit by setting the environment to Imperial standard.

Calculations for Various Products


Weights and volumes can be calculated using both SI Metric and Imperial standards, with both the ASTM 1980 and 2004 version tables included for user selection. The app can calculate for:



  • Crude oil

  • Products

  • Lubrication oils

  • Chemicals (e.g., vegetable oil)

  • Special applications (e.g., denatured ethanol)

Configurable Wedge Calculator


A configurable wedge calculator is included to assist with OBQ/ROB quantity calculations, accepting input in both SI Metric and Imperial units. Users can choose to use either table volume data or tank dimensions for the wedge calculation.

General Settings and Customization


In the general settings screen, users can select whether calculations are performed using SI Metric or Imperial units, and which ASTM tables version (1980 or 2004) is utilized.

Company Logo and Email Settings


Users can import their company logo by transferring the logo picture to their phone. At any time, two logos can be saved: one as the default and one as the active logo. Additionally, four default email addresses can be entered using the address book.

Templates and Customizable Reports


The notices of discrepancy and statement of facts section contains a variety of templates, along with a fully customizable version for each. Ullage reports are fully configurable, accommodating up to 53 tanks with as many grades as required. Ullages, temperatures, volumes, and densities can be entered in either SI Metric or Imperial units, with inline conversion available within the app.

Unlimited Report Saving


There is no limit to the number of reports that can be saved. Existing reports can be copied and used as templates for future projects. Users can name all reports as desired, keeping in mind that spaces are automatically replaced with underscores, and names must start with a letter, not a number or other character.
