The Way

In this research, the achievable precision level using mechanical datums for manufacturing has been studied. Specifically, the effect of how a datum is secured in a mechanical alignment system was studied with the aid of a high-resolution multidimensional optical position monitoring system developed for the purpose. The study shows that the way datum is secured can be a major factor affecting the alignment precision of a mechanical alignment system. For a datum prepared by randomly inserting dowel pins into precision bored holes, a common practice in industry, the precision level was found to be worse than 10 μm. The results also show that the precision level can be readily improved by addressing this major cause of inaccuracy. Different methods depending on manufacturing requirements and constraints have been proposed. Some of these simple procedures lead to more than an order of magnitude improvement in alignment precision. [S1087-1357(00)02001-3]

The ship escort mechanism and system in KRI / KAL in reporting the position of the ship beingguarded at this time is only limited to reports via radio communication equipment / HT. This causedthe KRI / KAL Commander's decision to be reconfirmed manually between the ship's escort Personneland the KRI / KAL Guard Officer. Therefore it is necessary to have a system that can monitor theposition of ship escort personnel periodically by applying LoRa (Long Range) technology integratedwith a GIS-based information system (Geographic Information System). The position monitoringsystem for ship escort personnel can send coordinate data from the Client transceiver device that iscarried by the ship escort personnel periodically with the 915MHz LoRa TM protocol and receive theclosest Gateway transceiver in KRI / KAL with the same frequency with an average time of two once asecond transmits, the coordinate data received is stored in the application server database monitoringthe position of ship escort personnel in the form of markers, so that the position of personnel ismonitored periodically and can be immediately reported to the KRI / KAL Commander as decisionmaker. This system can also receive coordinate data from several Client transceiver devices.Keywords: LoRa / GPS shield, ship personnel, GIS (Geographic Information System).

Position Monitoring

Floatover method has been proven a competitive installation technology in last thirty years. However, floatover installation is subject to a variety of technical challenges. Apart from weather restrictions, motions and position of the topside and deck transport vessel (DTV) should be strictly controlled during the entire installation operations. Therefore, a field monitoring system is essential to guarantee the installation safety. In this paper, a comprehensive introduction to the monitoring system developed by Shanghai Jiao Tong University is presented. The subsystems, including environment monitoring system, motions and position monitoring system, deck support units (DSUs) separating monitoring system, closed-circuit-television (CCTV) monitoring system as well as the integrated monitoring system (IMS), are proposed. Besides, the pre-installation surveys are also presented.
