Foreword The Global Wind Organisation (GWO) is an association of Wind Turbine owners and

manufacturers with the aim of supporting an injury-free work environment in the wind industry.

This Standard has been developed in response to the demand for recognisable Basic

Maintenance Training in the industry. The development of this Standard has been prepared in

co-operation between the members of GWO and has been based on work done by ATTP

(Adapting a Transparent Training Programme for wind energy) in 2014.

The objective of this Standard is to develop common industry training and Best Practice

Standards for the basic technical and safety skills required for the service and maintenance of

wind turbine generators across Europe and the globe.

This Standard describes the requirements for Basic Maintenance Training in the wind industry

that are recommended by GWO. Where national legislation sets higher requirements for the

training, the Training Provider shall incorporate these requirements into the training

programme. It is anticipated that additional Technical Training Programmes will be required due

to company or country specific requirements.

Introduction

Upon completion of the Global Wind Organisation (GWO) Basic Maintenance Training (BMT)

Delegates will possess an awareness of hydraulic, mechanical and electrical systems, preparing

candidates for working both on and off shore in the wind power industry. Each of these training

modules is not a stand-alone qualification but can be delivered independently of one another.

Target Group

The Basic Maintenance Training modules are targeted at candidates who have no previous

experience of hydraulic, mechanical or electrical systems but may also be used to up skill

candidates who have some knowledge of these areas in other spheres not specifically wind

turbines.

Overview The GWO Basic Maintenance Training is divided into the following three Modules:

Hydraulics

Mechanical

Electrical

Duration of BMT Modules Modules Duration

Hydraulics 16 hours

Mechanical 16 hours

Electrical 20 hours





/ 111

Legal Requirements The Training Provider shall identify whether national legislation sets other requirements for

Basic Maintenance Training. If so, the Training Provider shall incorporate these identified

requirements into the training.

Validity Period The Basic Maintenance Modules are enduring qualifications and therefore a validity period does

not apply to these modules. This is based on the assumption that the Delegate is actively

working in a wind turbine environment. If there is an extended period of absence from applying

the skills, retraining and recertification may be required according to national legislation and

company policy.

Delegate Prerequisites for the BMT All personnel participating in Basic Maintenance Training shall be medically fit and capable of

fully participating.

Training providers shall have a procedure that requires Delegates to sign a statement (see

Appendix 1A, Suggestion for Medical Statement from GWO) stating that they are medically fit

to participate in the Maintenance Training and that they do not suffer from any medical

illness or are under influence of any narcotic substance or alcohol.

Delegates’ signatures shall be collected prior to the start of the training course.

Physical Demands BMT Modules do not have any specific anticipated physical demands.

However, if there is any doubt regarding the medical fitness of any Delegates, the Training

Provider shall stop training the Delegate and seek a physician’s advice.

Note: Practical exercises shall be designed and delivered solely to meet this Standard and shall

not place any physical or mental demands on the Delegates other than those required to meet

this Standard.

modules they instruct. Instructors shall physically visit the tower, nacelle and hub of

the WTGs.

All instructors shall possess the appropriate competencies to conduct/assist the elements of

training they have been assigned to.

all aspects of the delivery of training shall be in accordance with this Standard.

Delegate Performance Assessment Delegates shall be assessed according to the learning outcomes by means of direct observation

and oral and/or written questions, where appropriate.

Training Providers shall have a documented procedure in place for dealing with Delegates not

meeting the stated learning outcomes.

Certification Training Providers are responsible for issuing a certificate directly to the Delegate upon
