As an IT Company, we have developed spreadsheet based files that have customised cargo work calculations (Oil Software) for crude oil and product tankers. Our standalone products (oil software) are designed for the business of shipping cargo (chemicals, oil or products) via shipping vehicles (tankers) or storing them ashore or in floating storage units (FPSO). We prefer to work with Microsoft Excel (images in site are snapshots of Lotus 1-2-3 files).
