The ZAKOS SHIP TOOLS CALCULATION is a fourth generation Integrated software package
for the Cargo calculation of a Tanker / Cargo Ship. The package is a menu driven and does
not require any previous experience on the use of computers.
The ZAKOS OIL CALCULATION has been designed and is ideally suited to assist Surveyors
Ship’s Officers for the Cargo / Bunker calculation of a Tanker / Cargo Ship.
