LNG CARGO SURVEY REPORT GENERATOR

Program for Windows

The LNG CARGO SURVEY REPORT GENERATOR is a fourth generation Integrated software package for the Cargo calculation of a LNG Tanker Ship. The package is a menu driven and does not require any previous experience on the use of computers. The LNG CARGO SURVEY REPORT GENERATOR has been designed and is ideally suited to assist ship’s officers for the Cargo calculation of a LNG Tanker Ship. The examples that will be shown and described are hypothetical and do NOT correspont to the ship’s tank Sound and Volumes from the Tank Ullage Tables. The example bellow is refered to a Demo LNG Vessel
