Bearing Wear Monitoring system fully integrated into Kongsberg Maritime
AutoChief C20 automation system
For 120k dwt product tankers
Bearing wear monitoring system sensors.
Kongsberg Maritime has been selected to supply its Bearing Wear Monitoring system
for a series of eight advanced 120k dwt product tankers presently under construction
at Hyundai Samho Heavy Industries in Mokpo, South Korea for the Norwegian ship owner
KGJS. Delivery of these sophisticated solutions is from May 2009 through 2010.
Monitors bearings in large two stroke diesel engines
The Bearing Wear Monitoring system is designed to monitor wear down of bearings
in large two stroke diesel engines. It provides an early warning in the form of
an alarm should any of the three crank-train bearings (crosshead, crank and main
bearings) get unexpected wear problems during operation and thereby enable the crew
to carry out preventative maintenance, avoid unscheduled maintenance, reduce off-hire
and ultimately cost.
Standalone or integrated
The system may be delivered standalone or integrated into Kongsberg Maritime's
K-Chief 500 marine automation and AutoChief C20 propulsion control automation systems.
In the case of the Jebsen newbuildings, the BWM system is connected to the AutoChief
C20 system via the common (CAN) network. The system uses the Bearing Wear Monitoring
mimic to display wear and trending measurements.
Optimal engine overhaul intervals
The tankers will be powered by HHI MAN B&W 6S70ME-C M8 main engines, which are
fully electronically controlled and monitored. The Bearing Wear Monitoring system
will be installed by engine builder HHI-EMD in Korea. The Owners consider the Bearing
Wear Monitoring system as logical step in order to introduce a proactive maintenance
system and ensure optimal engine overhaul intervals.
The open architecture of the Bearing Wear Monitoring system provides the opportunity
to add additional engine monitoring systems, such as bearing temperature and cylinder
In addition to using a reliable technical solution that can provide a reduction
in maintenance costs and downtime aboard its eight newbuildings, Jebsen will also
benefit from Kongsberg Maritime's extensive world wide service organisation, which
will ensure the highest possible system availability regardless of where in the
world the vessels are sailing.
