The procedure should be implemented at the beginning of each shift on the bridge by the OOW commencing a watch, after which the Change Shift test should give the OOW an overview of the system functionality to allow them to ascertain whether the system is ready for the shift period.
A set of a dozen tests is carried out during a period of one to three minutes, covering items such as GPS position verification, safety contours, checking safe course and the presence of updated charts for the next watch.
The procedure also contains shortcut buttons, with hints and assistance available where required.
Documentation of all checks is stored in log files, including the date, time, officer’s name and a short summary of the results of each test. The log files are available for replay and review after the test and can be viewed by Master or superintendent, for example.
"This innovative procedure will increase safety onboard and will help to prevent fatal mistakes caused when the officer who just began his watch is unaware of the exact setup of the equipment, possible offsets or different safety contours," said Maya Dagon Saffer, Totem Plus.
"The tests are designed to prevent erroneous decisions based on wrong interpretation or unawareness of the current setup."
