ASSET MANAGEMENT CHALLENGES

7

Asset Management Challenges

Initial Statement • It is common knowledge that high-quality data is invaluable to asset managers in decision-making relative to:

• Capital and operational expenditure; and • The scheduling of works in a safe and cost-effective manner.

• In the case of NPPs, this data is already readily available for use by the:

• Owner; • Operator; and/or • Contractor.

• However, the sheer volume of data and ease with which this information can be misplaced is all too

commonplace in the nuclear engineering sector

8

Asset Management – The Data Challenge

In the context of a sequential, document-based, complex engineering feat involving multiple stakeholders (e.g. an NPP), the optimal use of data is hampered due to 3 root causes:

Difficult access to information

No integrated data configuration management

Little use of digital solutions

The sheer volume of data leads to increased time and effort in retrieval and exchange of data amongst stakeholders

Risk of using superfluous data results in complex (also cost-inducing) modifications at later stages

Obsolescence and non-interoperable tools prevent from optimally leveraging asset data, leading to unexploited value

The consequence? Increased Time + Effort + Cost => Overall Lower O&M Performance

9

The Data-Centric Approach (DCA)

Data > Tools and Applications: a shared model is maintained and used as a common reference for applications that are added in to meet specific needs

Reduces quality escapes as synchronisation and updating of data is facilitated

Fosters data addition as the final model can be enhanced and new functionalities easily integrated

Maximises effectiveness when combined with digital solutions

DCA = data is the primary asset

DCA is an enabler

10

Asset management – The Data Opportunity

Engineering Data

Many data types can be collected … … and leveraged for different purposes

• Physical and functional attributes of the asset

Maintenance Data

• Recording of regular and event-driven inspections

• Inventory and spare parts

Asset Register

Asset Condition

Financial Data

Asset Performance

• History and traceability of operational life events

• Real-time data (sensor data…)

• Reliability, continuity

• Real-time monitoring

• Management of maintenance activities

• 3D modelling of post-design modifications

• Optimized work scheduling (4D) and dynamic task allocation

• Predictive maintenance

• Virtual preparation of critical

interventions (VR)

• On-site data access for field workers (portability)

• Data-driven O&M decision making

(ex-post and ex-ante analytics)

• and more …

• Costs and accounting

CASE STUDY: THE STEMA B.I.M. PROJECT

12

The STEMA Project

Project Overview • New-build unit for filtering and cementing radioactive

effluents on CEA MARCOULE site (south of France)

• Currently in commissioning phase

2 separate units for dumping of effluents and cementing process

Nuclear-specific equipment and process

Complex layout due to strong implantation constraints

Advanced safety features (LILW)

Assystem is the EPCm leader of STEMA installation

13

The Case Study

Design & Studies Construction & Commissioning Operating & Maintenance Decommissioning

Address sector-specific concerns such as complex time-critical interventions (e.g. NPP shutdowns), safety-critical systems LTO, asset knowledge management… Focus on business value by choosing data for which the most value can be created for the owner and the operator

Develop an Asset Model of the STEMA installation that will bring value during O&M

Case Study focus: lean, outcome-based DCA

Asset Data

The Output REAL-SCALE ASSET MODELLING REALIZED IN 4 MONTHS END-TO-END

• Simplified and functional 3D model of the installation complemented with an entire building pointcloud scan

• 4000 equipment with an average 30 data attributes per equipment (product data and details, cut sheets, manufacturer information and contacts, etc)

• Can be used as the basis to develop and deploy various utilisation scenarios

16

Utilisation scenarios

Identification of safety-critical systems

Direct access to equipment localisation and properties

Extraction of bills of quantities / bills of materials

Direct link to documents and datasheets

Realistic visualisation and accurate measurements in pointcloud vision

Space management (radiological zones, storage areas…)

17

Immediate Benefits

Reduction in number of surveys

THE ASSET MODEL OPTIMISES COST OVER LIFETIME THROUGH 4 PRODUCTIVITY LEVERS

More effective preparation of interventions

• Measurements are made in the pointcloud scan • Bill of quantities are extracted from the mock-up

• Work-zones are visualised prior to intervention • Quicker access to plant configuration and information

• Easier navigation, traceability and retrieval of information

• 3D mock-up for use by operator but also external contractors to implement modifications, perform early clash management, identify the most efficient and safe order in which to schedule works

Reduction in number of quality escapes

Optimised implementation of modifications
