FLAGSHIP, the Pan-European maritime
transport project part-funded by the EU,
has successfully developed software that
enables comprehensive suppression of
audible warnings in order to avoid large
cascades of alarms on the bridge and in
the engine room.
Called iCAS (intelligent Central Alarm
System), the system is designed to provide
a precise overview of the situation on
board as it develops while freeing up staff
to address the situation and follow the
vessel's routines without disturbance.
This element of the FLAGSHIP project
included both a theoretical analysis and a
practical exercise in the development of a
new integrated alarm system complete
with display. Proven methodology from
the offshore industry was used to create
an alarm shelving-and-grouping function.
The resulting system was used in a
simulation of a real incident on an LNG
tanker, where a full blackout generated
many thousand alarms over a few minutes
and more thousands during the next few
days. The system focuses on alarm
grouping in order to give overview and
criticality and also use temporary shelving
of spurious alarms to allow much-reduced
disturbance and more focussed operations
on board. Tests were made with
experienced bridge officers and the system
was very well received.
Geir Hasnes, Principal Engineer at
Kongsberg Maritime, commented: "In
addition to introducing the grouping
and shelving capability, we have created
a central alarm screen which delivers
an instant overview and situation
summary. The noise reduction in critical
situations is almost unbelievable. We are
confident that the concept will be
integrated into standard products over
the coming years.
"A full demonstration bridge with a
simulator incorporating the iCAS system
has been built at the Kongsberg Maritime
facility in Norway so that ship owners can
see the system operating in lifelike
conditions. Responses have been very
positive so far," he said.
Tage Thorsen of Teekay Shipping said:
"We had an initial demonstration of
the system in our office and the group
that joined the demonstration was
astonished by the "silent" bridge concept.
We look forward to seeing the system
demonstrated on the bridge simulator at
Mr Herman de Meester, Coordinator of
FLAGSHIP, commented: "FLAGSHIP has
pursued the twin objectives of reducing
still further both risk and the
environmental impact of the world's
commercial fleet whilst generating the
opportunity for real commercial benefits.
FLAGSHIP-iCAS is a further example of
the maritime industry collaborating to
improve performance and efficiency in
everyone's best interest."
The FLAGSHIP-- iCAS project was led
by Kongsberg Maritime in Norway and
was supported, delivered and trialled in
conjunction with MARINTEK, Teekay and
Autronica also of Norway, and ASME and
Minoan of Greece.

The Alphaconnect marine telephone
exchange, varying from eight to 256
internal phone lines, has received a
DNV type approval.
All relevant IEC 60945 tests, such as
vibration tests and electromagnetic
interference tests, have been successfully
passed by the Alphaconnect and its
marine telephone units P220, P411 and
P421. The certificate for the type approval
was received on March 13, 2011.
The Alphaconnect is a two-wire system,
making it an ideal telephone exchange for
the retrofit market. Because the ship's
cabling can be re-used in most cases it is
the most time and cost efficient way to
replace an old exchange.
