7 Offshore wind market overview / Doc.ID: Revision: Status:

8 OSVs needed for offshore field development / operation 1) Exploration 2) Field development 3) Production / Maintenance 4) Midlife upgrading 5) Abandonment Seismic research Exploration drilling Geotechnical research Drilling vessel Survey Offshore construction ROV support Diving support Pipelaying Heavy lift Derrick lay barge Inspection, maintenance and repair (IMR) Well intervention ROV support Diving support Offshore construction Standby Crane barge Accommodation Diving support Offshore construction Well intervention IMR Heavy lift Accommodation Diving support Offshore construction Well intervention Anchor Handling Tug Supply, Platform Supply Vessels 8 / 28th of July 2015

10 Vessels for offshore wind field development / operation 1) Exploration 2) Field development 3) Operation / Maintenance Survey vessel Guard vessel Jack up crane barge Jack up crane vessel Jacket installation vessel Accommodation vessel Crew transfer vessel (CTV) Cable laying vessel CTV for technicians Service operation vessel 10 28th of July 2015

11 Conversion opportunities for offshore wind market for existing OSVs / Doc.ID: Revision: Status:

12 Conversion from Seismic Survey Vessel Viking II - Eidesvik 12 / Doc.ID: Revision: Status:

13 Wind Innovation C-Bed Conversion into Windturbine accommodation and transfer vessel New equipment Gangway Boat landings Crane Container hangar DP thrusters Machinery Updated SPS Accommodation layout Increased accommodation LSA 13 /

14 Conversion from platform supply vessel - Vestland Cygnus 14 / Doc.ID: Revision: Status:

15 Vestland Cygnus Conversion into Windfarm support vessel New equipment Heave compensated gangway Boat landings Crane Accommodation modul LSA Updated Accommodation layout Increased accommodation SPS Sponsons 15 /

16 Acergy Viking 16 / Doc.ID: Revision: Status:

17 Degree of conversions / Doc.ID: Revision: Status:

18 Degree of conversion Major or minor conversion? Major Major update on the vessel. Ie. New rules at the time of conversion apply Minor conversion Minor change to the vessel function, weight etc Rules at the time of building the vessel still apply Key decision questions for the degree of conversion Will the vessel change operational mode? Will the vessel change the number of persons on board? Will the lightship weight and COG change significantly? Will the vessel change flag? Class / Flag to agree minor vs major conversion 18 /

19 Conversion vs newbuilding for a typical SOV tender / Doc.ID: Revision: Status:

20 Typical SOV design AHC gangway Crane 40 single cabins for technicians in nice cabins Boat landing(s) Container handling Deck area ERN m LOA m B Helicopter deck 20 /

21 Conversion vs newbuilding for a typical SOV tender Conversion Modified to the charter / owner need Shorter delivery time Lower re-investment cost / re-value of asset New or old rules Vessel overall age remain Newbuilding(NB) Tailored according to the charter /owner need NB delivery time NB price of vessel Always new rules New technology better utilized 21 /

22 Summary and conclusive remarks Offshore wind vessel market not yet mature Offshore wind market represent firm conversion opportunities for current OSVs Wind Innovation Vestland Cygnus Acergy Viking Tenders will require new built SOV vessels 22 /
