1 Development and demonstration of the Operation & Maintenance Cost Estimator (OMCE) to estimate the future O&M costs Dutch Offshore Wind Conference Session Keep on running René van de Pieterman Rotterdam, 23 January

2 Contents Introduction O&M cost modelling Operation & Maintenance Cost Estimator (OMCE) FLOW OMCE project Summary Objectives & Work Packages Progress and planned work Questions

3 Introduction: O&M cost modelling Why O&M cost modelling: O&M costs offshore account for 25-30% of KWh costs Optimizing O&M is essential; requires accurate estimates of (1) averages and (2) uncertainties Vestas, 2011 EWEA, 2011 NREL When O&M cost modelling: Deciding on new O&M contracts Either OEM or owner/operator Making reservations for future O&M budgets Either OEM or owner/operator (in-house maintenance) Optimise O&M at end of warranty period Continue with OEM or maintenance in-house Periodically for optimisation of accessibility Better vessels, new contract with shipowner 3

4 Introduction: O&M cost modelling Preventive: Condition based: Corrective: How often, how long? Time to failure? Failure frequencies of components Repair strategy: - maintenance actions (reset, visit, repair, replacement?) - # of maintenance actions - duration of maintenance actions - crew (size, length of working days, shifts) - types of access and hoisting equipment - spare parts used Weather conditions (wind speed, wave height and direction, current) 4

5 Introduction: O&M Cost Estimator (OMCE) Many inputs are required for O&M cost modelling These inputs can be derived from operational experiences ECN s conclusions from experience in the past: Data from offshore wind farms is being collected, but in an unstructured way Data needs to be analysed for reliability engineering and O&M optimisation (data information!!) Operators and OEM s own the data responsible for data collection and analysis Approach: Operation & Maintenance Cost Estimator (OMCE) 5

6 Introduction: O&M Cost Estimator (OMCE) Raw data Structured data Processing of data Information O&M strategy Strategy analysis Results Event List OMCE-BB Operation & Maintenance Component failure rates Unplanned Corrective Maintenance OMCE-BB Logistics Equipment and spare parts use Raw wind farm data OMCE-BB Usage & Load Monitoring Condition Based Maintenance OMCE Calculator Annual downtime and O&M Costs Remaining lifetime OMCE-BB Health Monitoring Preventive Maintenance 6

7 FLOW OMCE project Project objectives: A. Development of a baseline model of the OMCE by development of software and working procedures using data and feedback from an existing RWE wind farm. B. Make baseline model available to other offshore operators (commercial). C. Apply model for analysis of expected O&M costs FLOW demonstration (or alternative) offshore wind farm. D. Validate the model by implementation of the OMCE in the FLOW demonstration (or alternative) wind farm.

8 Introduction: Work packages Project Coordination ECN WP0 Knowledge Dissemination ECN WP1 Structured data collection RWE & ECN WP2 Development of OMCE BB s ECN WP3 Development of OMCE-Calculator ECN WP4 Implementation of OMCE concept ECN & RWE WP5 Quantification of uncertainties ECN and Ecofys Five work packages defined: 1. Structured data collection ( Event List ) Review data sources and Event List format Develop data capture procedures 2. Development of OMCE Building Blocks BB Operation & Maintenance and Logistics BB Loads & Lifetime & Health Monitoring BB Weather Conditions 3. Development of OMCE-Calculator Finalisation OMCE-Calculator demo Review specifications Programming OMCE-Calculator 4. Implementation of total OMCE concept Set-up baseline model OMCE for FLOW demonstration wind farm Implement OMCE in FLOW demonstration wind farm Evaluate and validate OMCE concept 5. Quantification of consequences uncertainties 8

9 FLOW OMCE project: Overall progress: Highlights Project kick-off meeting at in Amsterdam First O&M data was made available by RWE by July 2012 Updated Event List specifications drafted based on analysis of O&M data The OMCE Building Blocks O&M and Logistics demo software is updated During the project OMCE-Calculator demo was finalised and updated specifications are drafted and partially implemented based on feedback by RWE and demo users

10 Progress: WP1 Structured data collection Objectives: 1. Review data sources and existing Event List format 2. Develop automated procedures to update Event List with new operational data Progress: O&M data supplied by RWE as input for WP1 for 3 month period March-May 2011 ECN assessed O&M data to fill and further develop Event List format. Sufficient data available for further development of OMCE BBs (~92% of fields; Go/NoGo 1 = Go) Drafted updated Event List specifications Investigate possibilities to export maintenance data to Event List from CMMS (WP1.2) Raw data RWE Raw wind farm data Structured data ECN Event List 10

11 Progress: WP2 Development of OMCE BB s Objectives: Development of OMCE BB data analysis tools to obtain: 1) Component failure rates and logistics 2) Information on remaining lifetime Progress: Based on reviewed Event List format existing demonstration versions of BB O&M and BB Logistics updated for reviewed Event List format. BBs O&M and Logistics integrated in single software tool and send to RWE for review. Further development of new specifications ongoing Processing of data OMCE-BB Operation & Maintenance OMCE-BB Logistics OMCE-BB Usage & Load Monitoring OMCE-BB Health Monitoring Information Component failure rates Equipment and spare parts use Remaining lifetime

12 Progress: WP 3 OMCE-Calculator Objectives: 1. Finalisation OMCE-Calculator demo 2. Review specifications 3. Programming new specifications Progress: Q4 2011: ECN finalised demo version (v2.0). More work than expected. To compensate for delay in project ECN developed detailed specifications for selected new features and implemented these based on demo users feedback in version 2.1. O&M strategy Strategy analysis Results Unplanned Corrective Maintenance Condition Based Maintenance OMCE Calculator Annual downtime and O&M Costs Further development of new specifications based on review and feedback of RWE. Software Preventive Maintenance training given by ECN in May

13 Planning: WP 4 Implementation Objectives: 1. Set-up baseline model OMCE 2. Implement OMCE in wind farm 3. Evaluate and validate OMCE concept Progress: Work is scheduled to start in 2014 Request for project extension due to delays and at least 1 year of O&M data is preferred to evaluate added value OMCE (update input parameters and run OMCE-Calculator) 13
