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



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



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
