Wind Europe 2017 status and trends• The windfarm are located further away from shore outside visble range resulting

in deeper water developments.

• The windmill turbine trend is larger production capasity per unit, which in turn requires bigger propell diameter, higher towers and larger foundations.

• Two principal diffent foundation solution; Seabed fixed and Floating. The Productivity, CAPEX /OPEX are considered more favorable for the seabed fixedinstallations at less than 100 meters.

• Europe’s politicians still favors Green energy from wind mills and targets increased development activities with cost reductionsto achieve profitable un-subsideced energy production .

MC-7 market potensials and limitations

1. The MC-7 fundament can be used in approx. 50 to 150 meter waterdepths and covers today’s gap between floating and seabedfixed windmill foundations .

2. The MC-7 fundament can be used for both windmills and manned/normally unmanned windfarm power stations.

3. The MC-7 has it’s best competitive strength when completelyassembled and onshore pre-commisioned units are combined withthe MINT installation.

4. The MC-7 fully equipped unit’s, fundament with or witout towercan be delivered installed offshore .

MC-7 – Windfarm applications

MC-7 Wind - MINT Transport and Installation

MINT - Tool details

Towing from yard to site

MINT capabilities and limitations1. The installation method are by computer

simulations proven conseptually feasible.2. The MINT towing and installation method has

no limitations regarding the structures footprintnor tower heights.

3. The MINT installation limitation is vessel stability.4. Suction anchors has a both technical and CAPEX

advantage over piled structures. However, piledfoundations can be accommodated.

5. The wind turbine producers are in a «reluctantly modus» regarding horizontal transportation.

The Wind turbine designers should be challenged to optimize/reduceweights and size of the Nacelle to lower the CoG. This is challengingas the Ocean Wind market is only 3% of total.

Datasimulated analysis for transport andinstallasjon was based on MC-7 Wind for 120 meter waterdepth. Total weight :Nacelle 500 ton – Substructure 3000 ton.

Initial vessel stability assessment confirmed by the vessel crew. Skandi Acergy has necessarystability but Skandi Vega only stabile for approx.MC-7 -70 meters stuctures.

Simulated Analysis confirms Towing and Installation methode feasible in Hs 2,5 meter. 4 knots Towing speed @ Marin Linge field weather conditions.

(Remotely Operated Wellhead Platform)MC-7 Wind - Windmill

1. The verfied MC-7 Windmill was designed for waterdepths up to 120 meter following an «all internal» philosophy with J-tube pull – in of cables runninginternaly inside the column from seabed to termination point.

2. Tower internals with Main deck. Lower deck, elevator, auxilliary equipment, emergency escape ladder, cablegates and FiFi equipment.

3. Access by crew boat and W2W gangway from service vessel.

4. Ekstendable cargo deck

5. Integrated marine crane.

The shown MC-7 Windmill is for 70 meter waterdepth with a GE 6 MW Haliade turbine

Present deepest seabed founded Windmill developments stops at approx. 60 meter depth. Floating vindmills starts at approx. 100 meter.

(Remotely Operated Wellhead Platform)MC-7 Wind – Normally unmanned power stations

1) Main access by support vessel with W2W gangway and crewboat.

2) Ø9 meter diameter main column allows equipment installed inside upper part ofthe column. This lowers the CoG and reduces size and weight of the top side.

3) Mechanical handling by crane from vessels and through hatches to all levels

4) Helicopeter landing is an available option.

5) Emergency escape by Selantic shute from lower deck and stairs down to boatlanding area.Where an emergency raft is located.

MC-7 Wind – Construction strategy

Construction and commisioning strategy1. The selected structural assembly ,commisioning and load-out yard should be located near the

installation site and posess the required space and crane capasity. The load-out requires up to 10 meter water depth (for 120 meters structures).

2. The top-side and column mating and internal furnishings should be fabricated at the chosenassembly yard. The column structures will be supplied as company provided.

3. The substructures tubulars and suction anchors will be fabricated in specialized workshops and transported to the assembly yard. The top 15 meter of the main column will be produced first and transported to the assembly yard for internal furnishing.

4. The Top-side should be intergration tested and pre-commisioned in parallell with thesubstructure Cathodic protection process and assembly.

5. Upon completed pre-commissioning the Top-side will be mated to the substructure in horizontal mode and prepared for load-out.

The MC-7 substructuretubulares fits for serialmass production in specialized workshops.

(Remotely Operated Wellhead Platform)MC-7 Wind – Development strategy and way ahead

1. The MC-7 Wind strategy targets to install and set in operation; one full scale MC-7 Wind prototype structure for the purpose to demonstrate the technology and give market reference. Our preferred installation is a 6-8 MW windmill at waterdepth around 70 meter.This requires collaboration with end users/wind farm owners.

2. The MC-7 consept with the MINT installation method are in position to receive financial support from Innovasjon Norges Environment technology fund, or alternatively EU’s 2020 SMB program.

3. The participating end user must at the start of the project, committ to purchase/take over the MC-7 windstructure at a discounted price at the point in time when the installed structure is set in operation. The end user must also committ personnel in the steering committy and with technical personnel free ofcharge.

4. The project financing will be one construction loan where the end users financial commitment, together withcommitted contributions from Innovasjon Norge and Green Entrans assets will be used as collaterals. The project loan will be settled with the bank at the MC-7 handover settlement from the end user.

5. When the project is established, the joint organization will tailor the MC-7 design to meet the end user’soperating preferences, the installation sites environment and grid interface requirements.

6. Suppliers for Wind turbine, Substructure construction and Marine services will be qualified/selected. Vendorswilling to share risks and be self financed and insured will be preferred.
