About

IRIS

Read full description

Maritime students are required to accomplish a specific set of activities as part of the requirements for the completion of their academic and on board training. The school must monitor the individual and batch progress for purposes of making any necessary adjustment in time. This crewing monitoring system will greatly simplify this otherwise time consuming task by centralizing the updates in one location and automating the generation of the required statistics for reporting.
