Abstract

During scientificstudies on reciprocating self-ignition marine engines, varying data are often needed. Such data are often in various collections and obtaining some of these is very difficult. Therefore, as it was elaborated in the electronic database about the important marine reciprocating combustion engine producers for the needs of operating scientific investigations aiming at gathering the essential information and technical data in one set. This article also presents a reference to existing databases. Important and globally known companies, as well as their constant and variable data, were described. These data were obtained from various printed and virtual sources of information. These data were selected and compiled in the environment of the Microsoft Access computer program. The collected information was divided between main propulsion and auxiliary engines, containing data about manufacturers, types, and technical parameters of slow, medium, or high-speed combustion engines. This database is constantly updated and rebuilt according to the constructions and changes on the engine production market as the result of economic and ecological functions. It is a relative type database, which contains information about technical data of combustion engines. Marine combustion engines are usually operated for dozens of years after they have been produced, whereas producers merge, change their names, or stop existing. Therefore, a digital-knowledge-management platform was developed in the virtual space in which information on scientific and technical resources was integrated of competing manufacturers with the option of introducing updates.

Highlights

  • Any information is characterized by its content and form

  • Wärtsilä NSD was next to company MAN Diesel the largest company engaged in the production of marine internal combustion engines

  • The indicators used by manufacturers of marine internal combustion engines were distinguished: energy, comparative, natural and operational risk rates, etc

Summary

Introduction

Any information is characterized by its content and form. Because of its usefulness, information is divided into [1] useful, redundant, and parasitic, whereas the useful information can be divided into: basic, secondary, and additional. The database is an orderly collection of data, including thematic categories of data which are designed, grouped, and archived for customer satisfaction information on the needs of organization and that represent the current state of the objects [2,3]. These databases are appropriately arranged computer representations of existing (not necessarily physical) fragments of the real world, which is of interest to database users [4].
