5 SECTION 1 GENERAL 1.1 Introduction Foreword The number of ageing wind turbines which are out of warranty and which need careful maintenance and repair is steadily growing. Therefore the demand from the operators for high quality, effective and flexible services at their wind turbines increases in order to keep the power harvest as high as possible. Accordingly, the number of independent service providers in the wind energy industry is increasing. The industry faces the challenge of the appraisal of service performance by service providers suitable for individual needs. DNV GL supports the wind energy industry in this challenge with its technical expertise and impartiality by certification of services in the area of service, maintenance and repair of wind turbines. This DNV GL service specification (SE) is intended to define and ensure a unique high quality model for the organization and operation of service and maintenance activities in the wind energy industry. The service specification will be revised frequently in accordance with new experiences, findings and future technological developments. It is intended to set up a common understanding of quality of maintenance services Function of document This service specification (SE) specifies DNV GL s services for certification of service performance in the wind energy industry. The document provides: a common platform for description of the scope and extent of assessment and verification activities for the certification of services a reference document for the definition of the requirements for a certification according to the certification scheme a basis for the definition of the scope of work necessary for a certification of the services of an individual service provider in compliance with this certification scheme. A comprehensive scope of work shall be defined and contractually agreed between DNV GL and a service provider willing his service activities to be certified in compliance with this certification scheme Objective This service specification aims to set up a certification scheme for the certification of service and maintenance activities offered in the wind energy industry thereby following the guidance of ISO/IEC 17067:2013 /1/. The objective of certification of service and maintenance activities according to this service specification is to address the needs of interested parties within the wind energy industry by providing independent attestation regarding the fulfilment of specified requirements. This service specification serves as a publicly available description of DNV GL s certification services for service and maintenance activities in the wind energy industry. It defines the technical, managerial and safety requirements for the certification. The service specification will be referred to as a contractual document in the certification contract between the customer (typically service provider) and DNV GL Scope This service specification applies to certification of activities for service and maintenance of wind turbines exclusively carried out by the Society The scope of the verification covers all aspects from organizational, managerial, technical up to health-andsafety matters in connection with service and maintenance performance.

8 SECTION 2 CERTIFICATION PROCESS 2.1 General conditions for certification General Certification according to this service specification ensures a constant high level of professional qualification of service personnel and high quality level of the customer s performance of services. This covers all aspects from organization over working methodology and procedures up to the practical implementation into daily work routines in conformance with the applied rules and standards Quality management system As basis for the certification according to this service specification the customer should have a quality management system fully implemented in his organisation. DNV GL recognizes one of the following options of an customer s quality management system for the certification Option 1: certification according to the ISO 9001 (at least ISO 9001:2008) standard /11/ certified by an accredited certification body. DNV GL reserves the right to verify the customer s quality management system by documentation review or audit. Option 2: documented implementation of a quality management system equivalent to at least ISO 9001:2008 /11/. In this case DNV GL will perform a documentation review and a verification audit of customer s quality management system Deviations Deviations from the requirements and the process of certification of this service specification have to be authorized by DNV GL. Reasons and considerations leading to any such deviation have to be documented thoroughly. It shall be shown conclusively and in detail how the requirements of this service specification can be met in spite of the deviations. Appropriate documents shall be submitted. DNV GL shall assess the documents and decide in each individual case whether the deviation is admissible for the purposes of this service specification. In the case of details for which this service specification cannot be used, DNV GL reserves the right to proceed according to the intention of the service specification Applicable legislation and third party regulations National or regional laws and regulations should be taken into account for the certification. They shall be indicated and requested by the customer for certification for the individual case This service specification shall be observed as the minimum requirement, even if national or regional laws and regulations establish lower level of requirements. This service specification does not replace or substitute national or regional laws or regulations regardless which level of requirements they establish. In the case that the national or regional regulations define higher level of requirements they have to be observed as the minimum requirements. Moreover these statutory requirements may focus on aspects which are not covered by this service specification. This means that the observance of this service specification does not ensure that national and regional legislation and requirements are fully met. 2.2 Certification scheme General The certification process for services in the wind energy industry comprises: an assessment of the documentation of the services regarding organisation and structure as well as Service specification, DNVGL-SE-0448 Edition August 2016 Page 8

9 technical, managerial and safety requirements. This is connected with an assessment of the quality management system documentation if the system is not certified according to an international standard, see [2.2.1] verification of the service performance in accordance with the documentation and with the requirements. The verification will be done through audits performed by DNV GL on site at the customer s premises and during execution of the in-field service activities. Figure 2-1 gives an overview of the certification scheme. Figure 2-1 Certification scheme for service and maintenance activities in the wind energy industry by DNV GL Assessment of documentation As first step of the certification process the customer shall deliver his complete documentation of the services provided for assessment by DNV GL. The documentation shall cover all relevant aspects of the organisation, processes and procedures, personnel and resources, technical, managerial and safety issues as required, see Sec.3. The documents delivered to DNV GL for assessment should be written in English language. The use of other languages shall be notified and agreed with DNV GL during the enquiry for certification and before a certification contract is finalized. The working instructions to the personnel shall be in a language familiar to the personnel. This might be the local language of the country where the activities take place. The quality of any translations shall be assessed by DNV GL. This assessment is done by either scrutinising the translated documents or by verifying the qualification of the translator. Associated documents shall be submitted to DNV GL Assessment of quality management system The processes, documentation and recording of the customer s services shall be provided under the control of an implemented quality management system, see [2.1.2]. The complete quality management system documentation shall be delivered to DNV GL for assessment together with the documentation of the organisation and processes etc. as required under [2.1.2]. Service specification, DNVGL-SE-0448 Edition August 2016 Page 9

10 In case the customer operates under a certified quality management system according to the ISO 9001 quality management standard the QMS documentation needs not to be assessed. A copy of the valid certificate by an accredited certification body shall be delivered for evidence Verification audits General The service provider shall deliver objective evidence that his services are performed according to the documentation which has been assessed and in conformance with the applied standards. The scope of the audits shall be the verification of the implementation of the procedures and instructions necessary for an effective and safe execution of internal and external service activities of the customer. DNV GL shall nominate a qualified auditor (based on ISO 19011) for the coordination and performance of the verification. Depending on his professional background the auditor might assign a DNV GL employee qualified for the specific services to attend the verification additionally. The results of the assessment of the documentation, see [2.2.2] and [2.2.3], shall be taken as basis for the audits. During the verification process, the service provider and all his personnel shall closely co-operate with the auditor and shall provide free access to all relevant facilities, equipment, documentation and records. DNV GL shall prepare an audit plan prior to the audit. This audit plan (outlining organisational units, processes and elements to be audited) shall be agreed upon between the customer and DNV GL. The verification audits shall be performed in an effective and formal way. This means that an on-site verification audit shall consist of: an opening meeting with the provider s staff in order to agree on the scope and schedule of the verification collecting objective evidence of the effective implementation of the processes, procedures and instructions as well as of the performance of the services in conformance with the applied standards and with the documentation a verification of the facilities and equipment a closing meeting in order to present and explain the results of the verification audit. Findings from the audit shall be discussed regarding necessary correction, modification and improvements. All audit actions shall be done on spot check basis by witnessing selected processes and activities during normal service operation as well as by interview of the involved personnel. Depending on the size and organization of the service provider the verification shall cover different departments. In case any non-conformities are detected during the verification, the provider shall implement appropriate corrective actions within an agreed time-limit not exceeding 2 months. An additional verification audit may be required by DNV GL depending on the nature of the non-conformities detected in order to verify the implementation of appropriate corrective measures. Failing to comply with the above stated requirements may interfere the issuance of a certificate. The certificate shall only be issued after adequate solution of all open items. In order to thoroughly cover the services, their organisation, coordination and execution, the verification audits shall be divided in a verification at the office and installations of the customer and a verification of the service performance on site in the field Verification audit at the office and installations of the customer The scope of the verification audit at the office and installations of the customer shall be the verification of the implementation of the procedures and instructions necessary for an effective and reliable execution of the administrative and operative internal activities of the customer. DNV GL shall check, on sample basis, documents and records of service activities in the office (such as administration, turbine supervision/control, commissioning, instructions, training of staff and others Service specification, DNVGL-SE-0448 Edition August 2016 Page 10

11 relevant for the services provided) for objective evidence of the compliance with the procedures and instructions as defined in the documentation. Installations, stores and other premises as necessary for the performance of the services under consideration shall be covered by the audit. Sample service orders should be followed in a vertical way from service request over analysis and preparation down to execution and closing with reporting to the customer. DNV GL reserves the right to select one or, if deemed necessary, more of the customer s premises and/or installations for the verification audit Verification audit in the field The verification audit in the field aims to collect effective evidence of the implementation of the procedures and instructions for a qualified and safe execution of the external service activities of the customer in the field. DNV GL auditor shall accompany a service team during the execution of work orders in the field. In-field activities, which are included in the service under consideration (scheduled or unscheduled maintenance, turbine inspections, repair, etc.) shall be covered by the audit. The selection and extent of activities to be audited shall be agreed between customer and DNV GL during the contracting phase. The documents used and the records produced on site shall be reviewed on sample basis. The DNV GL shall observe and record that the performance of the work is in compliance with the instructions according to relevant safety requirements and safety instructions.
