IBS:Integrated Bridge System

As defined by IMO:-
"An integrated bridge system (IBS) is defined as a combination of systems which are interconnected in order to allow centralized access to sensor information or command/control from workstations, with the aim of increasing safe and efficient ship's management by suitably qualified personnel."

According to SOLAS, the Integrated Bridge System should be arranged in such a way that failure of one sub system does not cause failure of any other sub system. It should also be possible to operate each other equipment attached to the IBS individually or as a part of the system.

Moreover, on failure of any sub system, an integrated alarm system must provide a suitable warning to the officer on watch (OOW) of the potential threat.

An integrated bridge navigation system is generally connected to

1.Autopilot
2.Radar
3.Gyro
4.Position fixing systems
5.ECDIS
6.Power distribution system
7.Steering gear

8.AIS

9.Echo Sounder 

10.Navtex

Other inputs may be provided on different vessels.

though this system is still not mandatory but its still very useful in reducing workload of officer of watch. Providing a centralized control of the vessel navigation equipments helps to act OOW in quick and can say in no time with respect to current traditional navigation.

This system do have some drawbacks as all other systems like over reliance may lead to a catastrophic situation. If any of the input sensor is faulty it will result in faulty information.

After all the visual lookout,cross checking of informations and if not paperless position verification on paper charts must be carried out to keep vessel safe and efficient.
