• DNV GL Approach for Risk Management B
7
DNV GL © 2013
What are the significant risks?
Development Phase:
• Cost to reach to a financial decision
• Lack of reliable wind measurement for feasibility study
• Fix planning conditions without thorough engineering study
• Lack of logical engineering steps to obtain competitive bids
• Lack of rigorous design for electrical infrastructure
• Lack of O&M strategy
Construction Phase:
• Availability of installation vessel
• Weather
• Health & Safety
Operation Phase:
• Availability of service vessel
• Weather
• Health & Safety
8
DNV GL © 2013
Development Phase: Pre-Feasibility Study
Theme: Obtain key information with minimal development cost for a
sensible financial decision
a) Desktop review of available data
b) Preliminary Constraint Identification
1. Wind Resource
2. Water depth (bathymetry)
3. Distance from coast
4. Geology
5. Electrical infrastructure
c) Wind resource mapping – Mesoscale Modelling
d) Site visits
e) Wind turbine selection and wind farm layout
9
DNV GL © 2013
Pre-Feasibility Study: Technical Considerations
a) WTG Foundation Type Screening – considering the following data:
• Water depth, Scour potential;
• Geophysical & geotechnical data;
• WTG MW Class, and;
• Local vessel availability.
b) Construction Risks
c) Operation & Maintenance (O&M) Risks
d) Electrical topology risks
e) Implementation Plan – typical approach and timeline
f) Technical feasibility of the selected project – high-level
recommendations
10
DNV GL © 2013
Development Phase: Energy yield projection and interconnection
a) Energy yield projection – based on the wind map from the initial stage
b) Recommendations for wind monitoring campaign (location and method)
c) Recommendations for improving forecast data reliability
11
DNV GL © 2013
Cost Estimation
High-level development cost estimate, based on DNV GL’s in-house
European Offshore Model:
Taking into account:
• DEVEX
• CAPEX;
• OPEX;
• DECEX
• Project generation
capacity factors, and;
• Wind farm energy availability.
12
DNV GL © 2013
Environmental and Social
Environmental and Social (E&S):
a) E&S impact factors and affected stakeholders
b) E&S impact review for proposed offshore wind farm sites
c) Mitigation options
13

Front End Engineering and Design (FEED)
Purpose:
Explore the options available and evaluate their subsequent
technical and commercial implications
A FEED study will deliver:
Early understanding of project costs and economics
Optimal selection of design concepts
Identification of project specific supply chain and evaluation of its
capability to deliver
A well defined procurement strategy and the basis for an
effective tendering process
DNV GL Energy provides:
Project managers and a team of experts that are at the forefront
of their individual disciplines
Significant practical and commercial experience from the
development, construction and operation of numerous offshore
renewables projects.
