In the day-to-day ship operations, structural and machinery failures may lead to major accidents, endangering crew and passengers lives onboard, posing a threat to the environment and having a great impact in terms of ship performance and business losses. The ship onboard measurement methodology aims in addressing which systems should be monitored, when the scheduling of monitoring should occur, who will carry out the measurements and how. Information is acquired from data for machinery and structures collected from sources such as Classification Societies, ship structural drawings, planned maintenance systems, dry-dock reports and real time monitoring data. Through the examination of the above, the specifications of the various ship system parameters to be measured are conducted alongside the number of sensors to be installed. Different scenarios for monitoring the condition and performance of systems either on a day-to-day basis or periodically using either permanent sensors installed onboard the ship or portable equipment or also a combination of them is evaluated. Moreover, parameter measurements are concentrated on various systems temperatures, pressures and monitoring techniques such as vibration monitoring. The onboard measurement outcome will be further utilised for input in tools capable of calculating and assessing the performance and reliability of the ship, thus ensuring safe and efficient vessel operation. The deployment of the developed onboard system will be studied under realistic operational conditions for three different ship types, i.e. tanker, bulk carrier and container ship.
