2 Blue H EngineeringBlue H Engineering BV, fully owned by Business Creation Wind Energy AG, is the technology developer and design engineer for TLP based floating foundations.Having an expert team with capacities in: hydrodynamics, aerodynamics, marine contracting, offshore structural design & engineering and related certification works and procurement and project management.Active and available for floating foundation design and engineering applications, such as:offshore windoffshore power transformer stationsoffshore oil and gas rigshydrogen generation and storage at sea
3 Blue H floating wind deep-water foundation Since 2004 has the previous Blue H group been active in the development of the TLP concept for floating wind, as well as in the development of offshore floating wind farms, originally started for deployment in the Mediterranean Sea.Blue H Engineering has been driving its product design process to secure a market acceptable return on investment, in specific for low wind sites at sea as well as for harsh North Sea and Ocean environments for wind turbine capacities over 5MW.The for series manufacturing designed offshore wind TLP is the most stable (for turbine with large rotor diameters), robust and economical attractive foundation model for deep-water (>50m) applications .3

7 Blue H Engineering TLP foundation benefits for Offshore Wind FunctionalMaximum stability for floating wind turbine and so max energy yield generated from wind, transferred to the rotorSecured limiting the tilting angle and the accelerations of the turbine nacelleProven oil & gas exploration technology (deep water TLP’s)Designed for cost efficient series manufacturingNo seabed preparationAnchor design tailored to the seabed (solid sand, mud, rock)Tsunami resistantNo transition piece (as on fixed mono-pile foundations)Simple and robust systemSmall foot print (fishery)
8 Blue H Engineering TLP foundation Benefits for Offshore Wind Assembly at yardIncluding the turbine installation,pre-commissioning,connecting the tethers and anchorsDraught at yard harbor < 10mTransport and installationNo use of expensive installation vessels; towing out by tug-boat onlyLarge weather window: transportation (Hs 3m) and installation (Hs 2m) max 1 installation day neededSmall crew needed as all componentspre-assembled at yardUse of detachable stabilizers (ø10x15m)*during transportation and installation onlyNo use of diversNo hammering or piling
9 Blue H Engineering TLP foundation benefits for Offshore Wind MaintenanceInspective and preventive maintenancewithin the wind turbine sequenceReturn shipment for major repairDecommissioningComplete decommissioning as a reversed installation and transportation process, this includes removal of anchors.
10 Offshore wind farm CAPEX comparison Blue H Engineering TLP to Jackets Results Analysis and Review GL GH for 5MW units10
11 Cost of Energy from offshore wind farm with Blue H Engineering TLP foundations Includes:Price inflationPower delivered onshoreDecommissioning not includedBased on 500 MW wind farm with commercial available 5MW offshore wind turbines, at 100m sea depth, at 120 km off shore and an average wind speed of 10 m/s.
12 Offshore Floating Wind Market potentialAccording Garrad Hassan 6,000GW floating wind is technically, marketwise and economically feasibleEnd of 2011 offshore 3.8GW installed, 5.2GW under construction and 18GW for offshore wind projects has been consented (source: EWEA Offshore wind industry key report 2011)Further off shore and moving to deeper waters (>50m) is recognized as the next growth industry in wind requiring floating solutions (source: EWEA Offshore wind industry key report 2011)
13 Offshore Floating Wind Next steps for Blue H EngineeringComplete the Generic 5 MW Model (2013 – 2014):Proof of the innovation “self installing TLP” and its qualification (QTR).Document wave tank scale testing, and design verificationDesign and engineer, manufacture, install and test the full scale 5 MW Demonstrator (2014 and 2015)Commercial business ( 2016 onwards)
14 Offshore Floating Wind Opportunitydelivering low cost of sustainable energy, green jobs, large export business, environmental friendlyExcellent IRR for investors horizon 3 – 4 yearsConstruction of 350 MW offshore wind farm before the year 2020 and more to come.
15 Offshore Floating Wind Feel free to join the developmentHave an strong position when the commercial business starts.Perform product industrialization with strategic partner.Take a part in the supply chain for part of the GW potential for deep-water offshore wind.Co-operations with Research and Technology Institutes and Industrial PartnersThanks for the attentionNico C.F.
