The ShipWeight system serves two main purposes: Weight monitoring and estimation. During the weight monitoring process, data from weight take off during construction is structured and stored together with relevant parameters for the project.
When the project is complete and the weight data is corrected according to the results from the weighing or inclining test, the project is ready to be exported to the historical database.
As long as the weight monitoring of a project is ongoing, the data is stored in a project database, and cannot be used for estimation. The project database can contain several projects, and is separated from the historical database to prevent doing estimates based on incomplete project data.
When a project in the project database is complete, the data should be exported to the historical database. The historical database should contain data from all completed projects. When a new estimation project is started, estimation can be done on basis of the past project data in the historical database.
Usually the estimation progress continues until a construction contract is signed and there is a contract weight to relate to. Then a new ShipWeight project should be created and you can start weight control activities and weight take off.
During the weight control activities, the current project file can be compared to estimate and previous project revisions to find deviations and to measure the progress in the project.
When the project is complete, a new file is ready to enter the historical database, and the experience basis of past project data has increased. As more and more projects are exported to the historical database, the better the system will be to estimate new projects.
