A description is given of the SIMOS 31 (Siemens Monitoring System), a microcomputer-based integrated system for monitoring a ship's machinery installation and cargo handling with analogue and binary sensors. The system is modular, so that small or comprehensive monitoring systems can be realised. Recording equipment for an alarm recorder, data logger, and manoeuvre recorder are provided. Alarm systems are given by audible and visual indications, transmitted to the bridge, mess, and engineer's cabin in the case of unmanned engine rooms. The integrated cargo system used on LNG/LPG gas tankers monitors the following conditions: Custody transfer (in co-operation with Simmonds Precision, USA) for accurate tank level, temperature, and density. Temperature especially of the hull and insulated spaces. The pressure in the cargo tanks and insulated spaces, and the cargo-pump discharge pressure. The gas content in the atmosphere in the insulated spaces and service rooms. The system is also used on reefers and refrigerated containerships for temperature monitoring and data logging for cargo holds and refrigerated containers.
