DNV and GL Alignment - Main goals for the next 3 years
All legacy documents transferred to DNV GL system by end 2016
– Old documents will be maintained but to minimum required
– All documents, legacy and new, available on rules homepage asap
DNV GL will have service specifications in the field of:
Wind – Tidal - Wave and Solar energy
For wind two service lines will be provided:
1. DNV GL Certification scheme
2. IEC Certification scheme according to IEC 61400-22
5
DNV GL © 2013 2014-06-19
Alignment of Standards and Guidelines
DNV GL and the IEC based certification service will be provided
1. DNV GL certification service based on legacy GL Guidelines (GL-IV-1 onshore and GL IV-2 offshore)
GL Guidelines to be split into service specifications and several technical standards
2. IEC Certification according to IEC 61400-22 based on legacy DNV
documents (DSS-904 Type Certification and OSS-901 Project Certification)
– DNV-OS-J101 & J-201 to be incorporated into technical standards
Alignment will be performed in combination with technical maintenance

DNV GL Standards
The legacy GL Guidelines are split into several standards (each „Chapter“ becomes one Standard)
– Component certification easier (the client gets what he needs)
– Avoid duplication e.g. onshore / offshore
– Modular structure enables better maintenance
Full review of the content will be performed
– Include findings from harmonization process
– The content should stand for itself, Reference to existing documents possible (To be as self sufficient as possible)
– Extent of guidance as in legacy GL Guideline
– Always to give guidance leading to a safe product (where possible), DNV GL allow everyone to use individual solutions if they fulfil the safety level required

2. The DNV GL/IEC Certification
The IEC approach is harmonised globally within DNV GL, adding the best from both sides without cost increase and practical to work with (on-going projects not affected)
New DNV GL Service Specifications for Type/Component and Project Certifications to be published Quarter 4, 2014
Hearing process of Service Specifications involving technical committees and external parties Quarter 3, 2014

Harmonization of DNV GL Standards and Guidelines
The aim is to harmonise the interpretation and approaches between legacy DNV and legacy GL for
– Added value towards the sector – Incorporate latest experiences from
projects – Efficient way of working with certification – Delivery of same service world-wide Current contracts must be fulfilled with the
existing scheme (GL Guideline, IEC/DNV) National systems and requirements offered
as well 11

Projects will be checked for their
fit-for-purpose, and
trustable quality according to standards
state-of-the-art will be confirmed

Project-Specific Requirements of CVA activities
What is the extent of the CVA activities?
Formal requirements provided in CFR 30 Parts 550, 585 and 290
The requirements are mainly in the form of headings
Detailed specification is desirable for a uniform and consistent CVA approval
17
DNV GL © 2013 2014-06-19
Elements of an Offshore Wind Farm
Wind turbine generator and support:
- Rotor Nacelle Assembly
- Support structure
(Tower – Substructure – Foundation)
Substation
Cables
(Inter Array and Export)
What are the CVA requirements to these specific elements?
18
DNV GL © 2013 2014-06-19
CVA’s Primary Duties for Facility Design Review
Following are CVA’s primary duties as mentioned in CFR § 585.707:
Conduct an independent assessment of the design of the facility.
Certify that the facility is designed to withstand the environmental and functional load conditions.
Conduct an independent assessment of all proposed:
(1) Planning criteria
(2) Operational requirements
(3) Environmental loading data
(4) Load determinations
(5) Stress analyses
(6) Material designations
(7) Soil and foundation conditions
(8) Safety factors
(9) Other pertinent parameters of the proposed design.

Example: approval of the Rotor Nacelle Assembly (wind turbine)
The RNA (wind turbine) is part of the structure
The IEC system provides a way to ensure its structural integrity:
IEC assumes a Type Approval for the RNA (Component Certificate)
a) as part of the Type Approval a load “spectrum” is approved
b) for a specific offshore site loads on the RNA is approved
c) a site specific approval states that loads are within the approved spectrum
25
DNV GL © 2013 2014-06-19
Why is specific Offshore Wind approval requirements relevant?
• Increases investors’ and insurance companies’ willingness to engage
• Enhances competition
• Facilitates evaluation and comparison of proposals
• Drives offshore wind development ahead
• Facilitates trading of offshore assets

Benefits of independent 3rd party – Certification Body
Confirmation of requirements as stated by project developers, investors, operators, manufacturers governmental and non-governmental organizations
Building of trust in the design and construction (confidence in technical integrity) – Quality Assurance
Securing sustainable energy production throughout life-cycle
Secure investments and optimize return of investment
Secure better insurance rates
Minimizing financial project risks
Increasing reliability in the governmentals’ and consumers’ interests
