Avoiding failure at seaInvesting just the right amount in maintenance
A carefully planned and risk-based maintenance strategy: minimises risk of unexpected repairs costly off-charter
Achieved through: preventive maintenance proactive equipment condition monitoring corrective interventions

Avoiding failure at seaInvesting just the right amount in maintenance
ABB assessment delivers: complete strategic maintenance plan for on-board equipment tailored to customers market, vessel operating profile and
budget
ABB service contract: predictable annual costs that clarify maintenance budget allocates maintenance tasks optimally between supplier and
crew

Avoiding failure at seaPlanned preventive maintenance
Co-ordinated and planned maintenance programmes are: designed to provide lifetime reliability to electrical plant and
systems customised with:
technical support correct spares maintenance kits for upgrades
planned around a vessels sea-going time and plant schedules

Avoiding failure at seaPlanned preventive maintenance
Benefits include: Minimising risks of lost operation Improving environmental and safety issues Premature replacement of parts is avoided Extended life cycles reduce capital spend
investment can target more critical areas
Unplanned disruption avoided

Avoiding failure at seaInspection technologies lower maintenance needs
Failure or unplanned maintenance of large generator or induction motors must be avoided
Lead time for replacement units can be long and capital cost high
Cost is higher if vessel: is taken ‘off-charter’ cannot operate to performance levels

Avoiding failure at seaCondition monitoring
Provides valuable maintenance information Can be carried out while equipment is running Measuring on a regular basis, trends can be observed Allows overhaul to be planned ahead ABB has range of service technologies that:
analyse condition of many electrical items avoids need for costly dry dockings avoids general system outages accurately pinpoints condition of rotating machines offers new ways to:
improve operations increase vessel availability reduce maintenance costs

Avoiding failure at seaLEAP (Life Expectancy Analysis Program)
Provides precise information on remaining lifetime of stator windings of a high voltage machine
Significantly reduces risk of shut downs caused by unforeseen failures
Standard preventive maintenance can be planned around a vessel docking
avoids rigidly sticking to manufacturer’s preventive maintenance guidelines

Avoiding failure at seaMACHsense P
New condition monitoring service for large machines Holds three patents Provides early-warning to plant engineers Saves considerable costly downtime Detects potential failure well in advance including:
trouble with bearings rotor winding defects imbalances internal misalignments voltage abnormalities

Avoiding failure at seaMACHsense P
Available as: ‘Standard’ service - part of regular 6-month maintenance plan
‘Advanced’ service - one-time intervention to troubleshoot a specific problem
Key is ABB's intelligent software Analyses vibrations and other data collected from motor
with remarkable accuracy Analysis system uses algorithms that pick out specific
signals Algorithms used to estimate defect indices and criticality for
each specific machine Service extends working life of thousands of motors
running in critical applications worldwide

Avoiding failure at seaMACHsense P
Service provides accurate diagnosis reports quickly, with a summary delivered on-site includes integrated analysis for current, voltage and vibration rates defects clearly, by severity recommends specific repairs considers machine design in judging defect severity reduces unplanned downtime issues early warnings, allowing time for planning maintenance

Technicians at ABB service centres in 35 countries Technician attaches sensors to motor being tested at
customer’s site Certain sensors, using accelerometers, convert vibrations
into electrical signals Others measure electrical data Signals are picked up by a data collector, which is
connected to laptop In one day, a technician can usually test between four and
six motors

Customer immediately receives an on-site summary of motor’s performance
Presented as a colour-coded report rating four key areas anti-friction bearings cage rotor installation power supply
Customer receives more detailed report for those motors highlighted in initial site summary as being of concern
