DONG ENERGY – LEADING THE ENERGY TRANSFORMATION
Rena Paziorek, Local Stakeholder ManagerAnnual Plenary Meeting Wadden Sea Forum
Wilhelmshaven, 1.&2. November 2017

We have become too green for our name…
– ‘DONG’ is originally short for ‘Danish Oil and Natural Gas’.
– Over the past decade, we have transformed from an energy company based on coal, oil and natural gas to a global leader in renewable energy and a world leader in offshore wind.
– In line with our green transformation we have sought to find a name that reflects the green energy company we are today.
– In 2017, we divested our upstream
oil and gas business, and by 2023, we will be completely coal-free.

Why Ørsted?
– Almost 200 years ago, the Danish scientist Hans Christian Ørsteddiscovered electromagnetism, establishing the foundations for the way we produce power today.
– Hans Christian Ørsted’sgroundbreaking discovery was driven by his curiosity, dedication and interest in nature. These qualities also characterise us as a company –and are essential to changing the way we power the world. From black to green.

DONG Energy at a glance
* Share of the DONG Energy Group’s capital employed** On 24 May. 2017 DONG Energy entered into an agreement to divest its upstream oil and gas business to INEOS. On 29 Sep. 2017 DONG Energy completed the divestment of its upstream oil and gas business to INEOS.*** Following the profound strategic transformation from black to green energy and the recent divestment of the upstream oil and gas production to INEOS, the name DONG Energy does not fit the company anymore.
Consequently, DONG Energy will change its company name to Ørsted from 6 Nov. 2017

Location Distance to shore: ~54km from the German coastWater depths: Ranging from 23m – 30m
Wind resource
Proven technology
Permit and grid
connection
Tariff regime
High fixed price tariff for 8 years after commissioning
BKR01 is fully permitted for 78 turbines for
25 years
77 monopile foundations, one suction bucket jacket
prototype
Strong wind resource and high number of full load hours
Borkum Riffgrund 1
Offshore Converter station
DolWin 1
Export Cable Array cables
Offshore substation
The offshore substation bundles the electricity and sends it via a high voltage cable to the converter station
Monopilefoundations are suitable for sea bed conditions at site
A transition piece is installed on the monopile foundation as the connection piece for the tower and turbine
The turbines will be installed in five lifts: tower, the nacelle and three rotor blades
The array cables transports the electricity from the individual turbines to the offshore substation
Borkum Riffgrund 1: Overview
13
Foundations
The converter station and the export cables are constructed, operated and maintained by the transmission system operator, TenneT
The DolWin1 converter station has a capacity of 800MW and is connected to the substations from BKR01 and neighbouring windfarms. Here the electricity generated by the windfarms is converted into direct current before transporting it to the grid in Dörpen, Germany, where it is converted to alternating current and fed into the grid

It is controlled from shore via a control centre communicating with the station
Via Optic fibre cable
Gross weight of the whole structure 3,500 tonnes
Cross sectional area of the topside structure 465 square meters
The weight of the topside alone 1,850 tonnes
Total height above sea level is similar to that of the London Tower Bridge
app. 65 meters above sea level

Foundations
Status:• All monopiles and transition pieces have been
installed in due time• The German authorities have set strict and
challenging limits for noise production during installation. The successful use of an innovative noise mitigation system resulted in achieving the required limits and therefore an early full release for installation from the authorities
Foundations
Number of monopile foundations 77
Material Steel
Weight of monopile Up to 700 tonnes
Length of monopile Up to 60 meters
Diameter 6 meters
Length of transition piece App. 25 meters
Weight of transition piece App. 330 tonnes

Foundations – Suction Bucket Jacket Structure
Status:• The Suction Bucket Jacket foundation is a new initiative
on the project. It is a jacket structure on top of large buckets which are sunk into the sea-bed using "under-pressure", thereby making ramming obsolete and reducing noise during installation
• Construction site was at Bladt industries in Aalborg• Special measuring devices will be positioned on the
structure to provide detailed analysis of the foundation during operation
Foundations – Suction bucket jacket structure

Material Steel
Weight including transition piece App. 850 tonnes
Length 58 meters
Design Jacket structure with large suction buckets
Invention Well known from the oilindustry

Installation process for a Suction Bucket Jacket Foundation
1) The jacket with integrated suction buckets is lowered to the seabed
2) An under pressure is applied to the buckets by means of individual pumps
3) The hydrostatic pressure difference and the deadweight causes the buckets to penetrate the soil
Suction Bucket Jacket FoundationInstallation Process
The Suction Bucket Jacket is expected to contribute to the strategy of lowering cost of energy:• The installation process without ramming and noise mitigation will
reduce the installation costs• Reduction of the underwater noise level during construction is high
on the political agenda, particular in Germany
