Shipboard Safety Criteria Monitored By Siemens Computer

—Literature Available Marine computers are used to calculate and check shipboard safety criteria, primarily stability and cargo distribution, but also material stresses. The rugged Siemens SIMAC marine computer is this type of microcomputer which runs on the concurrent CP/M-86 standard operating system used worldwide.

A ship cannot be optimally laden without checking the safety criteria. To check the safety of a ship, the classification societies have made such marine computers mandatory for various types of vessels such as container ships, bulk carriers and tankers. A vessel's economic efficiency may be greatly improved by accurate and easy calculations. The COSYMAC (Computer System for Marine Calculations) program system developed by Flensburger Schiffbau-Gesellschaft is the basis for the cargo-dependent calculation of stability and of the structural stressing of the ship.

The operating system of the SIMAC marine computer makes it possible to process several different programs at the same time, thus also allowing the computer to be used for general shipboard calculations such as stores control, spareparts stocking and any kind of administration tasks on board.

Data is entered by interactive communication at the economically arranged video terminal. A printer is connected to the terminal which registers the results in the form of tables and curves.
