MARINE MAINTENANCE TECHNOLOGY INTERNATIONAL | APRIL 2016 ⠿ 23CONDITION-BASED MAINTENANCE (^) ⠿
Electrical power and automation
group ABB recently opened an integrated
Operations Center at Billingstad in Norway,
from where its engineers can connect
worldwide to any vessel fitted with ABB
technology. Sensors and software on board
the ship provide equipment condition and
performance data via satellite link allowing
ABB’s experts to remotely troubleshoot and
make informed judgments regarding vessel
and plant performance and maintenance
task planning.
The new center exemplifies ABB’s
marine integrated operations concept,
using the Internet of Things, Services
and People to connect ships, the owners’
technical headquarters and ABB’s support
departments, to monitor critical machinery
and equipment and key parameters. The
Swiss-based group
contends that this
integrated operational
approach offers a way
of working that can save
up to 50% of dry-docking
costs with ABB equipment.
A collaborative
research project by Nippon
Kaiji Kyokai (ClassNK),
Mitsui Engineering &
Shipbuilding (MES) and
MES Technoservice
has developed a next-
generation CBM system.
Designated CMAXS e-GICSX, it assists
in the early detection of abnormalities
in electronically controlled MAN two-
stroke diesel engines. The system detects
irregularities and provides onboard
troubleshooting regardless of the status
of the ship-to-shore telecommunications,
even without an internet connection. A
sophisticated algorithm is employed to
analyze correlations between sensing data.
Real-life big data tests
A seagoing demonstration and verification
program has been implemented, using three
ships managed by Mitsui OSK Lines (MOL).
The Japanese shipping group is investing
in the collection and collation of big data
from its fleet, with the goal of creating a
comprehensive integrated vessel operational
support network.
Tsakos Columbia Shipmanagement
(TCM) is equipping its fleet of around 70
vessels with an SKF condition monitoring
solution. The detailed maintenance program
offers a range of benefits, from preventing
unexpected failures in critical machinery to
giving early indication of potential problems
in auxiliary equipment, including engine
room fans, compressors, purifiers, electric
motors and cargo pumps.
Ships’ engineers have been provided
with a customized version of SKF’s Marine
Condition Monitoring Kit, using a handheld
monitoring instrument installed with
