Strukton

1921 Established under the name: “ NV Spoorwegbouwbedrijf ”, as a subsidiary company of Dutch Railways (NS)

1974 Renamed to “ Strukton ” after the merger with the Danish company Christians & Nielsen

2010 Acquisition by Oranjewoud NV, a private entity of Sanderink Invest

Operational Asset Management

• Define & Select: Your network and your network needs

• Measure & Monitor: How to get the data you need

• Data Management & Interface: How to manage data and make it user-friendly

• Analyse & Interpret: How to make sense of all that d ata

• Organise & Plan: How to put that data to good use

• Maintain & Feedback: How to keep improving your network.

The challenge

Introduction of Performance based contracts (PGO) :

• Competition : need for continuous improvement

• Focus on availability : reduction of failures

• Focus on costs : preventive maintenance

POSS® monitoring

Worldwide

Strukton’s Preventive Maintenance and Fault Diagnosis System

Over 10.000 assets are monitored by POSS®

point monitoring

Frequently obstructed movements due to:

• Poor adjustment of rolling construction

• Lack of grease on slide chairs

• Bent blades

• Electrical problems

(worn-out brushes, motor, etc.)

Fault diagnosis

Locking problem Motor problem

Functional point model

Data analysis

The next step

Railway maintenanceTo achieve further reduction in failuresand optimize maintenance (costs),we need to make the next step towards predictive maintenance

To enable this we need a set of tools to detect and predict failures in a veryearly stage in order to be able to plan/act (as possessions are restricting).

The predictions are to be accurate, reliable and provide information about whatfailure mode is going to occur.

Data Science ?

2015: Introducing Data Science

2015 : Pilot on POSS dataGoal: Discover what Data Science can bring to railway maintenance

2015/2016: POC

2015/2016 : Proof of ConceptGoal: development of a failure prediction model

Testcase:algoritm based on T-7dys behaviour

2016: Production

2016 : Development towards ProductionGoal (1): System architecture and code

Goal (2): Development of a ‘pipeline’

2016: Failure prediction

2016 : Failure predictionGoal (3): Improvement of algoritm

Lessons learned

• There´s lots of data

• Valuable information can be extracted

• (mechanical) failures can be predicted

• Enormous potential,we´ve just started

Think big, start small

Connecting data science todomain knowledge is essential

There’s always a correlation…. The challenge is to predict whatfailure mode will occur

Reliability and availability of (labelled) data is crucial
