2 Integrity, Health, Safety and Environment Always most important our core values Integrity Code of conduct Regular trainings Personal responsibility Leadership and culture Health, Safety and Environment (HSE) Hard work, never relax Leadership and culture Personal responsibility Focus on full value chain Risk assessments and mitigation Regular trainings 24/7 right balance Resource efficiency Slide 2

3 Offshore Wind Markets - Global Installed offshore wind mainly in Europe, China offers highest growth Europe Current activity mainly in UK, DE, and DK FR, NL and BL emerging - projects in development, large grid connections expected 2018/19 North America Limited to small demonstration projects, no significant projects until 2020 or later 1.2 GW 11.2 Europe 2025: 42 GW 24.4 China 2025: 46 GW China S. Korea Taiwan Japan 2015 GW Installed & grid connected GW 2025 GW Expected grid connection Expected grid connection Asia Current activity concentrated mainly to CN, fast growth expected starting in 2018 KR, TW, JP emerging (albeit slowly) Offshore Wind Market Slide 3 Source: MAKE, Global Offshore Wind Power Market march 2016

YE 2015 (Source: Make) Installed capacity by countries. YE 2020 (Source: Make) Installed capacity by countries. YE 2025 (Source: Make) 12 GW 33 GW 95 GW Slide 4

5 Offshore Wind Connections ABB offering Offshore and onshore AC and DC stations including buildings Reactive power control systems (FACTS) HV-Cables including land and subsea cable laying Training and advise on operation System studies including grid code compliance solutions and advise on connection to onshore main grid Maintenance contracts Slide 5

6 ABB Offshore Wind Connections Grid code compliance AC faults are not propagated through the HVDC system Grid code compliance done by HVDC Relaxed requirements on wind turbines Slide 6

7 ABB Offshore Wind Connections Fault ride-through Fault in the main AC grid No shut-down of the wind park Reduce stress on the turbines Increase energy yield Slide 7

8 ABB Offshore Wind Connections VSC technology Voltage sourced converters Self-commutated IGBT valves Multi-level topology ensures low losses < 1 % Requires no reactive power compensation Slide 8

13 An HVDC offhore wind solution concept Objective and customer benefits Objective Customer benefits Reduced total cost and delivery time Ensure predictable execution, based on defined scope/concept including well defined interfaces Modular approach A conceptual platform design, enhanced flexibility with regards to different requirements, site conditions and general business models Minimize offshore hook-up work and offshore commissioning Direct connection of Wind Turbine Generators Significantly (50-60%) reduce the topside weight as compared to the platform used in DolWin 2 (award date 2011) Increased number and smaller lifting vessels offshore can be utilized Increased number of yards for manufacturing Minimized interface work Pre-approved technical systems, smooth handling authority approvals No need for AC collector platforms Slide 13

14 Modularized platform 2 concepts 4A 3A REF DWA Model 3A 2 valve hall modules 1 ABB/YARD General Module 1 Jacket Minimize number of systems onboard. Planned to be built modular onshore, tested as far as possible Assembly of modules can be completed onshore or offshore, as best fits the project. HVDC functionality similar for 3A & 4A. One module common among yard and ABB Model 4A 2 valve hall modules 1 ABB General Module 1 YARD Module 1 Jacket Planned for client options and more systems is therefore added in the base case. Planned to be built modular, integrated onshore and tested, lifted offshore as a single lift. HVDC functionality similar for 3A & 4A. ABB scope in dedicated ABB Modules and YARD scope in separate module Slide 14

15 Evaluation of HVDC Platform Structures REDUCED WEIGHT AND VOLUME MODULAR TOPSIDE & JACKET Slide 15

16 Modular Approach The key benefits with a modular approach Parallel Engineering and manufacturing, Many potential yards/workshops and lifting vessels Equipment on ground level, separate testing. Reduce complexity / Manage Interfaces Dedicated ABB and yard module Easy to adapt options Drawbacks with a modular approach To a certain extent Increased Weight Some more engineering required.
