• 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

Risks Management in Construction Phase

• O2C Tool – Construction Modelling

• CapEx Risk Analyser Tool

• Project Certification

• Marine Warranty Survey (for Insurance)

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.

Key offshore wind achievements

First offshore work 1989; first major project commenced in1997

Over 350 separate renewable energy project assignments in the last 10 years across Europe, North

America and Asia

Currently involved in 80% of the largest offshore projects being developed worldwide

FEED studies (over 1,000 MW)

Project management of one of the largest offshore wind farm in the world (Thanet)

Full due diligence of 3 projects

Wind Measurements for over 8,000 MW

Primary provider - project certification services

Met platforms: Rhyl, Arklow, FINO 1, 2 & 3

Revolutionized the modelling of offshore O&M

Project Management for the Borkum West II Phase 1 offshore wind farm project (200MW)

Etc.
