2. We all know that the cost of delivering offshore wind projects can
be negatively affected through design and development inef-
ficiencies, piecemeal operations and environmental constraints.
So it is generally accepted that an integrated approach to design
and project development is desirable and in fact presents one of
the best ways to remediate issues quickly and keep costs down.
But do you know how to do this in a way that will work best for
you and reduce the cost of energy right from the very beginning
of your project?
At Royal HaskoningDHV and ECN, we understand precisely
where your real challenges are likely to be with such approaches
and how these are linked to the success of your bids. That’s why
we start by tailor-making solutions that:
• are right for you/your business
• will generate cost savings from project start, and
• continue to save you money throughout the project
5 Ways to Reap the Benefits
and Save Costs
Through our collective engineering and consulting experience
in wind energy, we have identified 5 areas where you can start
the cost saving process and improve your bid success. Each is
backed with a portfolio of world-class services and the exper-
tise to help you transform the integrated design approach from
standard concept to financial reality:
• Design that is well-tuned, efficient and embedded in O&M
• Constraint management from concept to development
• Financing efficacy to keep the cost of borrowing down
• Risk identification and management from design
and procurement, to construction and operation
• Insurances and warranties – selecting the options
that are right for you

5. Mitigating the pitfalls, minimising your costs
To create a strong business case and ensure delivery of the
lowest cost energy, we know how important it is for you to have
a tho-rough understanding of the co straints and limitations
of a site.
By focusing on analysing the risks, we can help you avoid unex-
pected expenditures once development has started.
We offer the comprehensive and cost-effective site feasibility
assessment services you need to support early decision-
making on wind farm development.
Services and solutions
for site feasibility:
• Wind resources and yield modelling
• GIS (geographic information system) based consent
and project constraint analysis
• Integrated environmental, physical, infrastructure,
economic and social feasibility assessment
• EIA (environmental impact assessment),
consent strategy, stakeholder engagement
strategy and survey strategies
• early technology advice
• early assessment of buildability and likely capital
cost-modelling
• capital funding feasibility and options appraisal
Enhancing wind farm design and operations
Achieving the maximum output from wind farm while mini-
mising the deterioration of equipment and O&M costs during
their lifetime takes planning.
A piecemeal approach can lead to waste, inefficiency and an
asset which fails to operate at full capacity.
To get it right you need to start at the design stage and follow it
through. We offer a package of services to help you do just that
– ensuring optimisation at each stage of development.
Services and solutions for wind farm
optimisation:
• layout optimisation to ensure efficiency and reduced
deterioration of turbines
• wind resource and yield modelling
• bankability reports and risk apportionment to
reduce borrowing costs
• design and location (bases and ports)
• EIA and consent negotiation – flexibility in requirements
• ensuring efficiencies adopted by D&B (design and build)
contractors
• O&M strategy development

6. Lowering your capital costs with smart decisions
Expert procurement and risk management strategies deployed at
the earliest stages of a wind farm project can result in savings of up
to 50 per in capital costs.
We understand that the key to reducing the cost of risk is to build
confidence. Relying on our expertise, experience and know-how can
help raise confidence in the risk assessment and as a result make a
significant contribution to reducing the capital cost of the project.
By taking a risk-based approach to construction cost management,
we can help drive down capital cost through effective costing and
allocation of risk that is based on an informed assessment of risk

7. Strengthening your business with
integrated strategies
During the development of a project it’s easy to forget
the impact of O&M in the long term. It’s often the ‘poor
and forgotten relation’ when it comes to planning, and
yet ignoring it can lead to spiralling costs down the line.
We know it’s vital to develop a single O&M plan and
strategy early on in the design phase of a project, and
then to continue to refine it during the project consent,
FID (final investment decision) and construction stages.
We offer a range of solutions and services to develop
an overarching strategy. In addition, we also offer
complementary support services including regulatory
compliance, data availability and agree structuring.
Services and solutions for O&M:
• O&M modelling for equipment and components
• proven wind farm management modelling to maxi-
mise power yield across the life of the project
• development of project specific environmental
management systems to ensure full regulatory and
reporting compliance
• health and safety management services to ensure
safe procedures are embedded in O&M and the
projectis fullycompliantwithregulationandreport
ing requirements
• project data management systems design based on
BIM (building information modelling) systems

11. Wind energy trends
Wind energy projects in the UK are entering a new phase.Turbines are getting larger, capacity
greater, associated infrastructure more complex, regulations more challenging, and – for offshore
developments – waters deeper.
Royal HaskoningDHV has been working at the forefront of the wind industry since its inception, from
early onshore wind farms and Round 1 offshore projects, to the giant offshore farms planned as part of
Round 3.The UK currently leads the world in offshore wind development.
Royal HaskoningDHV has expanded and shaped its experienced renewables team to handle the
demands of this fast-paced wind industry.We make our experience count, and we offer an unrivalled
service covering a wealth of specialist skills.Working alongside developers, from early site prospecting
through to the construction and operational phase, has equipped Royal HaskoningDHV with the
knowledge to provide expert solutions for challenging issues such as consenting, transport and
logistics, health and safety – and many more.We are flexible, experienced, responsive, and ready to
tackle new challenges as more ground-breaking projects are taken forward.

12. Dealing with EIA and consents
Royal HaskoningDHV is probably best known for the work it does on Environmental Impact
Assessments (EIA) for wind energy projects, and rightly so.To date, every offshore wind
energy project for which Royal HaskoningDHV has produced the EIA has been consented
first time.
Royal HaskoningDHV recognises the paramount importance of maintaining flexibility in
project design and within the supply chain at the development stage.We work closely
with project engineering teams to ensure that this flexibility is maintained within a robust
framework of EIA.This provides assurance to regulators and stakeholders that all project
permutations are assessed and that the developer understands and can mitigate the
impacts that arise once the final design has been fixed, thus reducing consenting risk. In
addition, Royal HaskoningDHV recognises that cumulative impacts are now a much more
significant element of the consenting process.We are seeing more instances, both onshore
and offshore, of multiple projects being developed in the same broad area.This brings
new challenges for developers; in particular in relation to potential cumulative impacts on
European designated sites.
The range of technical and support services for EIA that we provide puts us in a unique
position to offer our clients a full end-to-end service, offering expert consultancy and
engineering solutions for every aspect of wind energy developments.The experts in our in-
house team can cover ecology, hydrogeology, coastal modelling, noise, air quality, transport,
health and safety and a number of other specialist disciplines to help ensure the consenting
process is as smooth as possible.

13. The Royal HaskoningDHV team is primed to minimise and manage the risks associated with wind farm development, taking
into account existing conditions and those that the industry will face with the planned Round 3 projects.We want the wind
industry to be renowned as a safe environment for its workers, and we encourage best practice in this area through the
use of Hazid and Hazops workshops. Hazids (Hazard Identification) workshops bring together all the primary players on a
development to identify potential hazards, attribute responsibility to a person/contractor, and explore how those hazards
can be mitigated. Hazops (Hazard Operation) workshops are a more process-driven exercise which looks at the implications
of different scenarios. Conducting these workshops at the outset of a development is critical to establishing what the risks
are and taking early steps to mitigate them.
Developers are bound by the Construction Design Management (CDM) Regulations 2007, which apply to all projects
involving construction work carried out in Britain and its territorial waters.The difficulty is that this legislation has most
often been applied to land-based projects, which do not always readily integrate with marine activities and maritime
legislation.
Managing risk offshore
The regulations therefore need to be tailored to meet the
unique challenges raised by offshore wind energy projects,
such as: managing the risk of deep water, suitability of
vessels, heavy lifting operations, competence of workforce,
and structural integrity of the turbines and other support
structures, as well as the logistics of getting materials and
personnel out to the site under normal circumstances and
in an emergency.
As wind farm sites are proposed ever further offshore
developers will have to use larger vessels for installation
and to support maintenance. Royal HaskoningDHV is
working at Sheringham Shoal to overcome issues associated
with using an anchored, rather than a jacked-up vessel.
Whilst anchored vessels can work in deeper waters they
are subject to wave and tidal motion which makes them
more difficult to keep in position, involving the greater risks
associated with frequent anchor handling. Issues such as
this, and how to replace the use of divers who are currently
regularly used to fine-tune installations, will become more
difficult to overcome as the Round 3 wind farms start their
construction phase.

14. Site assessment
Royal HaskoningDHV is drawing on its coastal and marine experience to support the offshore
wind industry. Early assessment of coastal processes and seabed conditions can assist a potential
development to identify a preferred site or layout, determine design parameters and assess the likely
risk posed by scour, mobile seabed sediments and features such as sandwaves.
Royal HaskoningDHV has a heritage of
over 100 years of working with maritime
industries to provide metocean, geophysical
and geomorphological analysis of the sea
bed to inform the design or assessment
of the environmental impacts of maritime
infrastructure.
Royal HaskoningDHV’s team uses coastal
modelling techniques, supported by desk-based
analysis, and interpretation of metocean and
geophysical surveys to understand the seabed
and the physical processes that drive the system.
By undertaking analysis of historic maps and
charts, it is also possible to understand the
longer term changes at a particular site.These
techniques are also used to ensure that clients
have a comprehensive assessment of Coastal
Process Impacts in their EIA.
The company uses the latest 2D and 3D
modelling software and data analysis techniques
for waves and tides to help developers‘future-
proof’ their design of structures that will be
placed on the seabed; for example by assessing
the loading conditions and how wave forces and
tidal currents may induce processes of seabed
scour which could affect foundations. In some
cases the seabed can alter significantly in a short
space of time, so it is crucial that developers are
aware of the variability to expect in the seabed
where they plan to site an offshore wind farm.
When it comes to foundations, as the waters
where offshore wind farms are sited become
deeper, new solutions need to be found.The
traditional approach of constructing support
structures using monopile foundations
will become less viable and uneconomical.
Alternative, often more complex construction
methods will present more complex risk
management challenges.We are tackling these
issues head-on using our far-ranging technical
expertise.

15. Grid connections
Onshore and offshore grid connections can be substantial projects in their own right,
with their own complex barriers to consent. Royal HaskoningDHV is a UK market leader
in the Environmental Impact Assessment (EIA) of new onshore buried cable systems and
substation infrastructure.We have recently led the EIA studies for the offshore and onshore
transmission system for the Dudgeon offshore wind farm, including 45km of onshore
buried cables and one of Europe’s largest substations.This experience is being carried over
into Round 3, where we are providing both onshore and offshore EIA services to the first
phases of Seagreen’s Firth of Forth and Forewind’s Dogger Bank developments.
The planned Round 3 offshore wind farms will dwarf anything the UK has done before.
Transmission of electricity will occur over greater distances, potentially creating a range
of environmental, engineering and health and safety challenges to be overcome before
construction. Our team of experts on grid connections will assess the environmental,
technical and health and safety implications of burying cables in the seabed, from inter-
array to export cables, inter-connecting the devices and running the main export cable back
to the grid connection point onshore.

Transport logistics
One of the issues that inevitably arises when creating onshore wind farms or when transporting certain offshore wind farm
components by road is ensuring safe road access to the site, especially regarding the routing of construction traffic and the
abnormal loads carrying turbine components.With extended periods of construction work often necessary, it is vital that
vehicles of various sizes are able to get to the site without causing undue disruption on the local road network.
Royal HaskoningDHV’s expertise in transport and logistics
for the wind industry speaks for itself – we have never had a
project rejected on highway issues.
It’s important to consider every aspect of the route that
construction traffic and turbine transporters will take.
This means looking at the suitability of the existing road
alignment, including whether corners and junctions can be
negotiated by long vehicles. Attention should also be given
to the height of bridges, overhead cables and trees.You also
have to look beyond the existing conditions, for example by
finding out whether road or utility works are planned for the
route during the likely construction period of the wind farm.
Our team is able to advise clients on alternative turbine
choices if the highways infrastructure and access
arrangements will not allow their first choice of turbine.
Getting turbine components out of the ports that they dock
in can be the first challenge, and the wealth of experience
Royal HaskoningDHV has with working with, and designing,
ports often comes into its own.
