Case Study: Princess Cruises – Life Safety
Application
Integrating life safety equipment, control system and
annunciator using Lonworks and Modbus.
Problem
To implement a functional life safety system for less
than then $300,000 our customer was quoted by a major Building Automation
company.
To do so without major installation work.
To do so without interfering with the operation of the
ship.
Solution
There are 20 cold storage units in different locations
on the ship used for the storage of food, beverage and some other items. The cold rooms are effectively confined
spaces and a human can only enter the room if there is a life safety system. The ship is 25 years old. The life safety
system failed and no replacement components could be obtained.
By reverse engineering the cold room controls CAS was
able to design a fail safe system which utilized existing cables and installed
components which had not failed. A new annunciator in the engine control room
was implemented.
Results
Customer saved over $220,000 on each of two ships. CAS designed and built the annunciator, provided written instructions and drawings for installation. During installation support for the cruising ship was provided by phone and email. Installation and testing were completed in 2 days by 2 people.
