Blue H Engineering B.V.

The design engineer, system integrator

and technology provider

for

floating foundation systems and

multi-purpose platforms at sea


Blue H Engineering Profile Blue H Engineering is the expert design engineer for heavy dynamic loaded super structures at sea. In specific experienced in the design and engineering of floating foundations for offshore wind energy and single- and multi-purpose platforms for wind-, wave-, tidal power generation and aqua cultures, fish- and seaweed farming, including energy storage at sea. Our team is active in design and engineering of: - Tension Leg Platforms (TLP’s) - Semi-submersibles - Spar Buoys - Multi-purpose platforms and are specialized in the integration of offshore wind turbines on floating platforms. Technology provider by performing technology transfer and manufacturing-, transportation- and installation support, maintenance and operation Smart Offshore Wind energy design, integrated generation with storage at source.


Blue H Engineering floating offshore wind expertise and technology Since 2004, the Blue H has been the pioneer in developing deep water floating foundation technology for offshore wind turbines, designed to unlock the vast potential of offshore wind at an economical cost. The performed design and engineering we can disclose: As the first in industry, Blue H developed the floating foundation technology for offshore wind, and constructed the 560 tons offshore wind TLP and installed this prototype in 2008 and tested up into 2009, moored in the Adriatic Sea 113m deep.

The goal was to show the world that floating offshore wind is feasible and to learn from experiencing the engineering, manufacturing and erection of turbine at the yard, loading-out, towing-out and installation at sea, of such a complex structure. Blue H started then to design a 1,5–2.0 MW TLP (FCU project) with an own development of an offshore wind turbine. As the market developed rapidly to larger multi MW offshore wind turbines, this development project was stopped end of 2010.


During 2010 an extensive R&D study Diwet5, as ordered by the British ETI (energy technology institute) has been performed. This concept was based upon an hybrid (concrete–steel) TLP which resulted in an economical and technical feasible 5MW design, which have been in depth reviewed by the experts of:

With the result that ETI concluded in 2010 that such a floating foundation system would reduce the cost price of generated electricity to a level of GBP 105/MWh delivered onshore. This was substantially lower than at that time achieved by fixed foundation offshore wind farms. The hybrid concrete–steel Blue H design ETI-Diwet5 with its own two-bladed wind turbine technology.


Currently, Blue H Engineering developed floating foundation technology for commercial available offshore wind turbines for the capacity range of 5–12 MW and developed an attractive cost effective design with unique “self-installation” method at sea, delivering lowest Levelized Cost of Energy for offshore wind power delivered onshore. Its generic TLP model for 5MW offshore wind turbine installed at sea deeper 50 meters, is already a more cost efficient solution then fixed jacket foundations.


Blue H Engineering floating foundation technology benefits

Innovative cost effective technology Robust and optimal integrated design for harsh marine environments generating substantial more energy than possible at shallow water sites (benefiting from higher and more consistent wind speeds further off-shore) and best floating stability Wind turbine assembly at yard (avoiding expensive installation at sea) Wind turbine pre-commissioned at yard (low onshore cost) Offshore wind TLP design for efficient serial manufacturing Transportation by towing out with one AHTS vessel (anchor handling tug and supply vessel) only Self-installing process and method Several cost efficient anchoring methods available depending on the type of seabed Easy and low cost decommissioning of wind farm by reversed process.


Environmental attractive technology No need for seabed preparation works No hammering and piling Complete and easy removal of equipment at the end of its life (by reversed installation process) Small footprint (minimal use of sea and maximum available area for fishing industry) No visual pollution (sites to be positioned much further from shore) Potential of multiple use of platform (aqua cultures, fish and seaweed farming)

Blue H Engineering services and technology providing Blue H Engineering has the capability and capacity to serve clients with design, engineering and project management for their heavy dynamically loaded applications of multi-body superstructures at sea.

Blue H Engineering’s expertise is to deliver a design optimized for: • manufacturing capability of the region (use available capacity) • logistic capability of marshaling harbor (minimum infra structural

adjustments) • regional available transportation and installation capacity (prevent

heavy investments in heavy lifting and installation ships) • offshore wind turbine • metocean conditions at the site • extreme local conditions (earth-quakes, tsunamis, typhoons) • sea depth • type of seabed (ranging from hard rock to solid sand)


and to serve by providing project management, procurement, logistic and quality control services. Blue H designs, based on proven oil and gas exploration TLP technology, are offering:

• the industry most stable floating foundations and so highest offshore wind energy yield,

• floating foundation designs for 5 to 12MW for deep-water applications,

which are more cost effective than 45 meters deep jacket foundations,

• an environmentally friendly installation process

• minimal foot print of use of sea

• lowest costs for the installation at sea

• lowest cost for complete decommissioning at the end of the wind farm life.

The final design will be owned by the client (transfer of IP Rights) Blue H Engineering has a core competence team with expertise on:

• Hydrodynamics, hydrostatics and response analyses

• Loads and dynamics for system integration (wind turbine – floating foundation)

• Structural design, engineering and certification

• Strategic purchasing and procurement

• Project management manufacturing and wind turbine erection

• Project management superstructure transportation and installation at

sea and has an extensive offshore engineering network to support the team. Blue H Engineering has developed its own unique numerical/computational design tool to optimize designs of heavy dynamically loaded multi-body superstructures.


Blue H Engineering economical designs are characterized by:

• Pre-commissioning erected offshore wind turbine at yard harbor (low onshore cost)

• “Self installation method” using detachable stabilizers or installation

transportation (ITS) system and no heavy lifting installation vessels

• Semi-submergible gravity anchors (if gravity anchoring is preferred)

• Robust integrated designs for 5 – 12MW

• Design for serial manufacturing

• Design for turbine erection and installation at harbor (low onshore costs)

• Mooring with anchor designs for different seabed types of: mud, sand,

clay, limestone, gravel, rock (hard and soft)

• Grip-lock system to hold the tethers during life time

• Cost reviews and CAPEX comparison reports from DNV GL

• State of the art engineering documentation and asset management control set-up.
