Abstract

Bridge system on a cruise ship with two shafts and up to 4 bowthursters can have tens of buttons and lamps on its control console for propulsion and steering control.

These buttons and lamps are used to control or show the status of only the most critical systems related to maneuvering and operation of the ship. When an unexpected failure or situation occurs, user might need to use, in a short timeframe, a function that he has never used before. These actions require always user interaction and they cannot be automated.

When engineering a system all fault cases and the corresponding correct procedures to them are known. Therefore available options for the user in these situations are always limited. In the improvement, the amount of options shown to the user is limited by showing only the data that is available or needed (on a touch screen) in the current situation. This will guide the operator to make the right choices on failure situations.

Another option is to highlight the usable buttons on button panels by using a neutral colored light to light up the button frame. Different color can be used to indicate which buttons should be pressed in that current failure situation.

This kind of limitation of options and guidance to the user in difficult fault situations will greatly improve the situation awareness and add safety for both people onboard and to the machinery.

SITUATION AWARENESS IMPROVEMENT FOR BRIDGE CONTROL SYSTEM

Background

Bridge system on a cruise ship with two shafts and up to 4 bowthursters can have as much as 80 buttons and 119 lamps on its control console for propulsion and steering control. These but- tons and lamps are used to control or show the status of only the most critical systems related to maneuvering and operation of the ship.

When an unexpected failure or situation occurs, user might need to use a function in a short timeframe that he has never used before. He might have the training to use it, but to find that one critical button from 80 buttons and situation critical data from 119 lamps makes this opera- tion even more difficult or even impossible to do in time. These actions require always user in- teraction because they cannot be automated.

Current bridge systems have all the buttons and lamps laid out on the console and it is up to the user to know how to use them in every possible situation. There are no guidance available at all.

Improvement

When engineering a system all fault cases and the corresponding correct procedures to them are known. Therefore available options for the user in these situations are always limited. That being said, we can reduce the amount of options shown to the operator by showing only the da- ta that is available or needed (on a touch screen) in the current situation. This will guide the op- erator to make the right choices on failure situations.

Another option is to highlight the usable buttons on button panels by using a neutral colored light to light up the button frame. Different color can be used to indicate which buttons should be pressed in that current failure situation. This kind of limitation of options and guidance to the us- er in difficult fault situations will greatly improve the situation awareness and add safety for both people onboard and to the machinery.

Following advantages are obtained:
