| Case
study 2 - SM30 upgrades for Pullmantur Cruises |
| |
|
|
|
Pullmantur Cruises is Spain's largest cruise line and one
of the most rapidly growing cruise lines in the world. This
hugely successful Spanish firm was virtually unknown outside
its native country until late 2006 when Royal Caribbean announced
that it had purchased the company.
During 2008 Royal Caribbean transferred the "Empress
of the Seas" and the "MS Sovereign of the Seas"
to the Pullmantur fleet and began a program of planned upgrades
to the fleet.

The renamed MS Empress and MS Sovereign
both had legacy Philips SM30, SQ45 amplifiers and associated
equipment installed as the ship's public address and emergency
sound system.
Although the SM30 and SQ45 is well known within the industry
to be extremely robust and reliable, a planned upgrade to the
SOLAS approved Bosch Praesideo was required to take advantage
of improved digital technology and changes to safety regulations.

Maintenance of critical components was also becoming
an issue as SM30 control equipment and SM30 microphone
Callstations had ceased production and spare parts were
becoming difficult to locate.
In 2002, Robert Bosch GmbH had acquired Philips Communications
and Security Inc (Philips CSI). Continuing its 'evergreen'
policy the Bosch Praesideo was developed as the direct
replacement and upgrade path for the Philips SM30. It
was designed to integrate with existing installed SM30
so that a gradual changeover from SM30 to Praesideo
can be achieved without replacing a ship's complete
safety and evacuation systems.

This project looked at replacing
the SM30 control equipment and custom built SM30 Callstations
with two Praesideo NC's (Network Controllers), to provide full
redundancy, yet retain the Philips SQ45 amplifiers that power
the ships loudspeakers. Minimising disruption and upgrade costs.
The installation of two Praesideo NC's would comply with the
latest maritime standards for evacuation at sea and maintain
full functionality of the system, in the unlikely event of failure
of any single Praesideo NC. |

the installation of Bosch Praesideo emergency sound systems
