Operation and Maintenance Management Software for Off-  and Onshore Windfarms

Organize spatially distributed maintenance activities on windturbines, ensure troublefree operations and manage projects cost-effectively: GS-Service supports operators of wind turbines in their various tasks.

This way benefit from the Maintenance Management Software by using intelligent deployment planning and efficient task processing of technicians, in clear warehouse management and the deployment of transport vehicles. Engineering and service tasks for off- and onshore windturbines are so complex in their implementation and subsequent operation, they increasingly require the introduction of maintenance planning software. This software should be able to initiate and map the various topics. 

At the same time, a software solution has to fit the specific requirements of the industry and offer the best possible support in resource planning and execution and in documentation of service assignments.
 

 

We have been supporting the Meerwind Süd/Ost wind farm since 2013 with our maintenance management software GS-Service for the administration of their 80 wind turbines. Up to 2,000 documented components are installed on each wind turbine.

Each component is integrated into a structure according to RDS-PP and can be identified quickly and unambiguously. In addition, each possible activity is assigned to a component of the wind turbine.

By now, our management software is being used at three additional offshore wind farms and by onshore service providers.

Origin of the Maintenance Management Software

As part of the publicly funded research project "DispoOffshore", operator requirements for a maintenance management software were recorded in detail. Subsequently, the required topics were integrated into a software solution so the management software offers the site manager maximum assistance during planning.

In cooperation with the Forschungsinstitut für Rationalisierung (FIR) e. V. at the RWTH Aachen and the Hochschule Zittau Görlitz (FH), a suitable software solution was developed in which a meaningful daily planning is calculated from the multitude of requirements by using a parametrizable algorithm.

The software takes into account travel times and employee qualifications as well as priorities of the tasks and the workloads of the teams. The site manager has the option to change planning manually. The tool can also be used to create the necessary documents and proofs, for example for customs, so legal security is guaranteed as well. The employees receive their assigned work orders, which are then completed on site on the wind turbines with notebooks or tablet PCs.

Workflow Management Software - Task Management and Disposition

During operation, status messages are generated via the central control system, which result, for example, in a troubleshooting task. The tasks must be given high priority in daily planning. Planned recurring inspections and defect rectification orders are also available. Several hundred tasks are quickly completed at a wind farm.

The site manager´s or scheduler´s job is to decide which repairs and maintenance are to be carried out on the following day and in the next few days. They have to consider all necessary parameters in the task management.

A controlled and good overview of handy technicians and teams, available spare parts and means of transport enable efficient resource planning and profitable task management.

Due to the large number of systems, the site manager must also keep an eye on spatial distribution of employees so travel times are as short as possible and the sequence of assignments is carried out in the most economical order possible.

Factors of workflow management

Many parameters need to be taken into account in task management: 

  • Different qualifications of the employees required and their resulting responsibilities
  • Availability of technicians according to the operating calendar
  • Necessary and available resources from materials management
  • the necessary prioritization of the work orders to be completed

At the same time, site managers and logisticians must take into account which means of transport are available to the employees for their tasks when managing measures, since changes in the weather may require them to redeploy to other workers.

For an offshore assignment it is often considered whether a helicopter should be used in urgent cases - for example, when increased wave height no longer permits CTV deployment.

  • RDS-PP Structure Library
    The RDS-PP structure has established itself in windfarm management for the identification the turbine structure and components. The Reference Designation System for Power Plants (RDS-PP) is a further development of the power plant designation system KKS with extensions for new technologies in electricity and heat generation.
  • Certificate examination of employees
    In the area of HSE (Health and Safety Executive), consistent monitoring of personal training and certificates is required. You can immediately see which employees need to renew important qualifications.
     
  • PPE - Personal protective equipment
    The regular safety checks of all personal equipment required by law guarantee a high standard of safety. Each inspection is electronically documented and automatically rescheduled according to its validity period.
     
  • Electrical testing of portable equipment according to DGUV
    The check of portable electrical appliances according to DGUV regulation 3, in the sense of accident prevention regulation, concerns all objects which serve the application of electrical energy. Each check is documented in the software application and automatically rescheduled according to its validity period.
  • Capacity calculation for planned operations
    The availability of the employees depending on their individual qualifications and the quantity of planned work orders enables a capacity calculation to determine the utilization of resources.
     
  • Shift planning as daily or weekly planning
    The dispatching of emergency forces and the distribution of teams takes place via a partially automated planning board in which much relevant information such as wind and weather data can also be made available.
     
  • Route optimization for mission planning
    In onshore deployment planning, the route is automatically optimized. Locations can be approached in an efficient sequence. The travel times are directly calculated to the timetable.
     
  • Creation of customs lists and deployment documents
    Depending on the area of the wind farm various documents must be generated automatically, usually immediately before the trip. They serve as orientation for daily scheduling, e.g. for the captain, but also as official documents for customs or other authorities. 
  • Work preparation and warehouse management
    A warehouse clerk receives a picking list before deployment and assembles the necessary spare parts for each team. A barcode controlled warehouse app supports them doing their daily work.
     
  • Control of external service providers
    A dedicated web portal enables communication with external service providers. Workorders can be created or retrieved there. Release takes place as permit administration for the respective assignments.
     
  • Troubleshooting by using notifications from SCADA systems
    Unplanned requests usually result from errortickets in the condition monitoring system. Work orders can be triggered automatically and displayed to the site mananger for planning purposes.
     
  • People Tracking 
    The current location of the employees is documented in real time by the software solution and is visualized by an overview map, particularly for coordination in cases of emergency.
