Typical Class Notation: Self-elevating Wind Turbine Installation Unit SPS Crane Unit OPP-F E0 DYNPOS-AUTR DPS2 NAUT-OSV(A) CLEAN DESIGN Some WTIV being upgraded (leg extension, crane higher capacity) due to trend for larger Turbines from 4 (2010) to 8 (2016) to 12MW (near future). Typical 5-6MW, 150m dia, 400T, 110m height. Unit name Build Year Flag Unit manager Yard name SEA CHALLENGER 2014 DNK A2SEA A/S COSCO (Nantong) Shipyard Co., Ltd.

10 Many different concepts on drawing board 10

11 WTIV Class and Statutory Regime Class: fit for purpose Rules developed from Heavy Lift ships and Jack-ups Statutory: :? Jack-up? Cargo ship? Special Purpose ship? No mutual approach for certification amongst the Flag states Commonly MODU-Code and SPS-Code applied simultaneously 11

12 WTIV Classification Regime cont d Decision about slider position currently prerogative of the competent Flag State As clear IMO guidance is currently missing, early consultations between all involved parties required (owner, yard, class, flag) Meanwhile DNV GL supports owners / yards finding the most suitable regulatory approach for maximized availability of their particular vessel and obtaining flag state agreement of this approach 12

13 12m ~8m righting lever [m] Examples of Exemptions justified to Flag Challenges in applying SPS-Code to WTIS: WTIS Hull cross section Geometry of WTIS: WTIS relatively much wider than conventional vessel Solution: ``maxgz`` 40.00m PAX / SPS 2 1 ``Area 3040`` Hull cross section 32.20m heel [ ] -1 13

14 12m 8m Examples of Exemptions justified to Flag cont d Challenges in applying SPS-Code to WTIS: WTIS PAX / SPS Hull cross section 40.00m Hull cross section Double bottom: h=b/20 required by SPS-Code Pan-max Cruise Ship (B=32.20m): h=1.61m WTIS (B=40m): h=2.00m WTIS higher DB-requirements despite lower speeds and much smaller length than pan-max cruise ship Problems for WTIS such as weight (jacking) space above double bottom Solution: 32.20m 14

15 WIND FARM SERVICE VESSELS or CREW TRANSFER VESSELS (CTV) Windfarm service vessels (typical smaller service crafts), are on the range 20m to 40m length. There is a large number of these vessels classed by DNV GL, ranging from catamarans over SWATHs to trimarans. Typically in aluminum, high speed. Typically used for day transfer or day service. 15

16 WIND FARM Service Operation Vessels (SOV) 16

17 WIND FARM SOV FLEET SOVs are recent trend in Europe for larger, dedicated, fit for purpose mother vessels to service wind farms w/ technicians living on board, using special gangway systems and some having helideck, typically 60+ people onboard (in addition to crew) All 6 current operating and 4 under construction Wind Farm SOVs are classed by DNV GL Typical Class Notation: Offshore service vessel SPS BIS BWM(T) Clean(Design) COMF(C-3, V-3) DK(+) DYNPOS(AUTR) E0 HELDK LCS(DC) NAUT(AW) Recyclable SF Unit name Build Year Unit manager Yard name Operator TBN 2018 Østensjø Rederi AS Astilleros Gondan (hull 470) DONG TBN 2017 Østensjø Rederi AS Astilleros Gondan (hull 471) DONG Bibby WaveMaster Bibby Marine Services Damen Shipyards Galati WINDEA Leibniz 2017 Bernhard Schulte Shipmanagement GmbH & Co.

26 Cost of offshore wind has fallen faster than anyone was expecting External factors - reduced material prices Technology development larger and more reliable turbines Increased competition / Lower cost of capital Project learning & operational excellence 142 UK %? LCOE ( /MWh) 2010/ Target 2015/ Since 2010, over 9.5bn has been invested in offshore wind in the UK, another 18bn will be invested in projects by 2021, making offshore wind one of the biggest infrastructure programme in the UK.
