Shipowner'S Impact On Planned Maintenance System Database Quality Grades Resemblance Equalization

This paper analyzes the shipowner's role in the development process of ship's computerized planned maintenance system database, paying specific attention to his/her impact on database quality grades resemblance equalization. The paper describes the database development process from the realization that the database is needed to the installation on board vessel, and all shipowner's and developer's actions in the process.The computerized databases of five shipping companies were tested using questionnaire developed for this purpose.
