Since the beginning of this year, we have been working with several companies on an offshore project to
store hydrogen.
The hydrogen is to be produced and stored on a floating platform off the coast. Several storage units are planned that can be exchanged. The storage units are planned to be made of UHPC concrete.
For the construction, it is currently planned to use UHPC concrete with a compressive strength of over 200 MPa. Currently, the static and constructive calculations are being worked on. The first drafts are expected in two months.
UHPC Ultra High Performance Concrete is a material with immense possibilities. WPE DK International has more than 30 years experience in the development, production and industrial applications of UHPC Ultra High Performance Concrete materials. We produce UHPC Mortar, UHPC Castable, UHPC Shotcrete, UHPC Offshore, UHPC Security, UHPC TopLayer und UHPC Wear Protection
Offshore hydrogen storage system made of UHPC
New use of recycled windmill rotor blades as aggregate for UHPC concrete
UHPC grouting material is used worldwide in the
in the offshore and onshore industry worldwide for more than 25 years.Mostly, UHPC Grout has been used to make transition pieces and foundation systems for wind energy, oil production, tidal power plants and floating windmill platforms. There are also plans to use UHPC concrete as corrosion protection for the systems in these areas. It would be a safe, easy to install, cost effective and durable solution. Another development for the future is the combination of UHPC concrete and recycled rotor blade material. Several thousand used rotor blades from offshore and onshore wind turbines are lying on the ground around the world to be recycled or disposed of. Storage has become a very big problem in some countries. In many industrial
applications we use glassglass fibres, carbon fibres or plastic fibres asaggregates to our UHPC concrete.
In order to carry out reuse, recycling and upcycling as standard in the near future, special UHPC concretes are the ideal combination partner. It should also be possible to add construction material from wind turbines to our UHPC with appropriate processing. This could then possibly be used again as foundation material for new onshore or offshore wind turbine.
UHPC in alternative and regenerative energy production
Hydroelectric power plants or storage power plants
Due to the extreme corrosion resistance of UHPC concrete constructions with a much higher reinforcement density per volume can be used. This can significantly increase the strength of the construction or the wall thicknesses or layer thicknesses can be reduced while maintaining strength.
In the right combination UHPC is very resistant to wear and cavitation.
Since UHPC already reaches 70% of its maximum nominal strength in the standard quality after 48 hours and in the special quality after only 12 hours.
UHPC is available as mortar, casting material and shotcrete material.
Some tidal power plant systems are already being used in Europe and Asia. There are now a lot of technical variations of tidal power plants for the coasts but also for directly in the sea. One thing all needs a stable seawater resistant and durable foundation.
Based on the experience gained with the foundation systems of the offshore wind power plants, high quality UHPC materials are ideally suited for this purpose. In particular, the enormous adhesive power of UHPC in anchoring and bolt system is required here. What is once shed in a UHPC foundation can no longer be removed from the foundation, even with enormous forces. Not only in this regard, UHPC is many times superior to normal standard concrete.
UHPC - Use in recycling plants
UHPC Ultra High Performance Concrete
application in recycling plants for
- Synthetic substance - Recycling
- Plastic - Recycling
- Military equipment - Recycling
- Paper - Recycling
- Metal - Recycling
- Precious metal - Recycling
- PCBs - Recycling
- Nuclear - Recycling
The reprocessing of paper, plastic, chemical
waste, rubber and metals has become an
extremely important commodity market for
the producing industry. Much more metal
raw material is recovered from reprocessing
than mining.
The material required for reprocessing is
stored on large exterior and interior surfaces.
Here, the bearing surfaces are mechanically
attacked as well as the corrosive liquids
extremely.
Many existing concrete surfaces show
considerable damage, which does not
guarantee the smooth and safe transport
of the stored goods for reprocessing.
UHPC floor systems are best suited for
these loads due to their hardness and
wear resistance. These floor systems are
laid without joints. Due to the very high
material density, penetration of corrosive
liquid with professional installation is
almost impossible.
UHPC floor and pavementsystems are
UHPC Phalt and UHPC TopLayer.
UHPC Phalt is a combination of traditional
asphalt with UHPC concrete. The result is a
ground or street blast with the flexibility of asphalt
and the very high compressive strength and
wear resistance of UHPC concrete. The
processing and processing time is extremely
easy and cost effective.
UHPC TopLayer are floor coverings made of
UHPC concrete for very high mechanical loads.
The material thickness is only a fraction of
standard screeds or concretes.
UHPC TopLayer are extremely corrosion
resistant and can be installed almost on any
flooring. UHPC TopLayer achieve compressive
strengths of far more than 140 MPa

UHPC - Alternative engery power plant
All of our UHPC special concrete products have a minimum compressive strength of 120 MPa / 17400 psi. UHPC concrete can install on concrete and steel structures, for new constructions as well as for repairs. UHPC concrete for wear and corrosion protection can be processed as mortar, grout or shotcrete.

The future of offshore wind energy with UHPC
Jackets, Gravity base, Tripods and Tri-piles systems are also used depending on requirements and needs.
UHPC is used in all foundation techniques.
Monopiles
UHPC grouting material is used for the connection between monopile and transition pieces.
Monopiles have been deployed with even larger turbines in even deeper waters, currently up to 41 meters. 9 diameter monopiles are now in production. We estimate that more than 2000 monopiles worldwide have been installed with UHPC grouting and transitions pieces.
- Very good fatigue properties
- Minimal shrinkage
- Extreme bond between UHPC grouting material and steel
- Fast setting development
- Very high inner cohesion
- No mixing with sea water
- Absolutly seawater resistant
- Very low hydration heat
- No corrosion
Jackets
Jackets are generally considered to be better than monopiles for seabeds where the substrate is poor or deeper water. So here UHPC can be used in the "transition piece" and in the lower foundation.
Gravity foundations
Are well suited for rocky sea beds. The complete foundation system can be manufactured on land and then pulled into position with a ship and then sunk. Depending on the design, the entire foundation piece can be made from UHPC
The future - with floating foundation design
This includes- Spar
- Semi-submersible
- Barge
- Tension-leg platform
Spars
First systems are already being tested. In the near future, a wind farm with spar systems is to be built off Scotland.
These systems can reach total lengths of over 90 meters, with about 75 m of them underwater. The entire underwater area can be made of UHPC.
Semi-submersible
Similar to the Spars, the whole underwater construction can be made of UHPC.
Barge
Barge systems are actually classic pontoon systems. There are now UHPC concrete available which in addition to their high strength also swim without the large cavities inside the barge must be generated.
