Situation
The Norwegian
company Unitor was contracted to provide the air conditioning and fire
damper systems for 2 Royal Caribbean cruise liners. The ship is divided
into 9 fire zones. If a fire occurs in one zone, the other fire zones on
the ship are designed to be isolated from the fire. This means that the
control and monitoring systems in each must also be able to operate in
isolation while being able to be monitored centrally from the engine
room and the bridge.
Solution
During the
building and delivery of the ships, Unitor installed a SAIA PLC control
network with a SAIA PLC and a Measuresoft Scada system in each fire
zone. The SAIA PLCs were connected on a dual 485 network while the
Measuresoft Scada systems operated over a dual redundant Windows
networks. The Measuresoft Scada systems were run on embedded systems
with no permanent monitors. These systems in turn are monitored via a PC
network in the engine control room and on the bridge using a Measuresoft
developed graphical interface as shown below. The interface allows each
room on the ship to be monitored using a graphical navigation facility.
The solution also provides alarm monitoring and alarm logging.
Measuresoft staff worked in the shipyards and during the sea trials on
the ships to ensure that the solution was delivered on time.

Benefits
The system
graphical interface is highly configurable.
The system is
highly reliable with the fire zone system not having to be rebooted for
many years.
The graphical
interface has set a standard in the shipping industry for presentation
and screen navigation.
The system is
easily upgradeable to new version of Windows and new PC hardware as was
the case in the refurbishment of the ships in 2005.
