Our company has been using Navatom for a very long time. Navatom has nice charts, graphs and other analysis capabilities. These analysis show all of the data we have input into the software very fast.
It is also very easy to plan maintenance, and drydocking tasks. All the modules in the software are integrated together which helps. As an example, you can create an equipment deficiency and tie it to an equipment, and report downtime that occurs in that equipment due to that deficiency, then postpone that deficiency and the maintenance of that equipment to a drydock, and you can track them on the calendar, then add an invoice to that tasks, and now it's in the running cost.
These integrations are amazing and very intuitive to use, and yield amazing combined analysis which clearly shows the weak points you need to improve upon.
