NEW SHIP TECHNICAL CONTROL SYSTEMS FOR THE ROYAL NORWEGIAN NAVY

In 1975, the Royal Norwegian Navy entered an extensive new construction program. In this connection it was necessary to decide the future policy of machinery control techniques. Working groups consisting of members from the Naval Material Command, Norway, and the Ship Research Institute of Norway have developed a new operational management system including Condition Monitoring concepts and Data Techniques. The system consists of two basic parts, the shipborne system (SHIPCON) and the shorebased system (SHORCON). The principles have up to now been applied to various projects, of which details of two are given. The system is based upon micro-computer techniques and data storage on magnetic tape for Condition Monitoring--and Pattern Recognition processing ashore. Efficient man-machine communication has been accomplished by means of alpha numeric displays and graphic color monitors. For the first project it was necessary to keep weight and volume of the control equipment at an absolute minimum. Due to high speed, light weight, 4-stroke engines, condition monitoring data cannot always be accomplished by direct measurements. Methods for indirect establishment of parameter values are therefore introduced. Additional data processing onboard is provided for special monitoring of certain short trend condition developments. For the second project, graphic color screen monitoring methods are utilized for supervision of remote controlled systems.
