Product Portfolio
  • Concept

  • The BARD Group as contractor offers turn-key offshore wind farms, including the engineering and construction of all necessary components for highly productive offshore wind farms - starting with internally developed steel foundations which are custom-made for the specific locations of the seabed and ending to the rotor blades which are installed with a customised jack-up vessel. Service and maintenance come also from the BARD Group. The so-called SWATH tender enables our service technicians to quickly call at our wind energy converters. We are glad to present our knowledge and our technique to potential investors. We are awaiting your questions. Please contact us.
      • WEC

      • Our Wind Energy Converters have been designed specifically with the rough environment of the high seas in mind. We rely upon tried and trusted concepts and components, thus balancing safety and innovation.
          • Rotor blade

          • Our blades are in their dimensions aerodynamically ideal and are designed for an optimal output at high average wind speeds. A relatively slow rotation speeds and state of the art production techniques ensure an especially long lifespan. BARD blades rotate on average approximately 20 percent slower than conventional rotor blades, minimising the abrasion at the top of the blades and thereby reducing the maintenance effort substantially.
            We rely on glass fibre reinforced plastic components on basis of expoxy resin which is a material which has proven itself for the construction of rotor blades since more than a quarter of a century. All three-dimensional blade components have a core of plastic foam.

          • Nacelle

          • The rotor shaft revolves in a two-rowed tapered roller bearing which is mounted together with the gearbox upon the main bearing which is made out of vibration-reducing nodular cast iron. The three-bladed rotor is arranged towards the windward side. A ‘”BARD 5.0” achieves its nominal output already at a light breeze and does not need to be turned off before the wind reaches a wind force of 11 Beaufort (equivalent to heavy storms of 30 m/s). Five azimuth drives between tower and nacelle insure that our wind energy converters are always ideally positioned in the direction towards the wind. The performance is controlled by the blade angle. As the controls of the blades are buffered by battery power, they are able to turn the blades in a resting position.

          • Foundation

          • Our ‘Tripile’ foundation system has been patented and is produced in series by our subsidiary Cuxhaven Steel Construction GmbH in Cuxhaven. It is suitable for water depths of 25 to around 40 metres and is compacter, lighter and cheaper than other offshore foundation systems. The supporting crosspiece and struts are welded from flat steel elements. The joins between the supporting crosspiece and the three foundation piles are glued with special cement. All the assembly work can be done with the heavy-duty crane on our construction vessel.
        • Installation

        • For the installation and operation of our wind farms, as well as their service and maintenance, we utilise our own self-elevating crane vessels. This makes us independent from the availability of such vessels in the market. The particular features of our jack-up vessel permit continuing with the installation works even during adverse weather conditions.
              • Jack-Up-Barge

              • This means that we possess the key tool for building an offshore wind farm. Having our own jack-up platform makes us flexible and gives us the time leeway we need for installation and operation. The ‘Wind Lift I’ provides a secure and stable work platform even with wave heights in excess of 3 metres and up to wind force 7. It has a helicopter landing deck and offers accommodation for up to 50 people.

          • Operation

          • A tailor-made service and maintenance concept is of utmost importance for the safe and reliable operation of an offshore windpower plant. We offer an integrated concept with a permanently crewed platform in the windfarm itself and dedicated access and logistics solutions.
              • Transformer Platform

              • The offshore wind power plants are electrically connected to the accommodation and transformer platform.
                On “BARD 1” the alternating current from a total of 80 wind turbines is converted from 33kV to 155 kV and then transferred to the neighbouring converter platform “BorWin 1”.
                “BARD 1” was installed in the North Sea in the summer of 2010. It is a floating and self-installing platform. Several tugboats were needed to tow the platform to the project area where it was positioned. The “substructure,” as the foundation is called, was then lowered to the seabed, whereby the topside of the construction lifted itself out of the water automatically. The “topside” – the actual platform with the accommodation unit and the two transformers – was completed at the Western Shipyard in Klaipeda, Lithuania. The installation of the foundation structure and the hydraulic components took place at the Harland & Wolf shipyard in Belfast, Northern Ireland. Currently, a commissioning team is stationed on the platform. Later on the platform will accommodate service technicians working around the clock at the offshore wind farm “BARD Offshore 1”.

              • SWATH Tender

              • Our special vessel for transferring service and maintenance personnel at the offshore wind farm will be delivered in spring 2010.
                The wind farm tender is being built at the Abeking & Rasmussen shipyard using SWATH@A&R technology. SWATH refers to a special hull shape that is less affected by swell. This means that the SWATH wind farm tender will be able to carry personnel to the wind turbines and back to the accommodation unit on the transformer platform safely even in rough seas. The special vessel will be stationed at the wind farm. It will have a crew of three and be able to carry a maximum of twelve passengers plus a payload of around 4 tonnes.

              • Bard Control Centre

              • Unique in Europe - BARD Control Centre for Offshore Windfarms

                From today on, BARD Service GmbH is capable of monitoring and managing offshore windfarms with more than 400 wind energy converters and a power output of more than 2.000 MW in accordance with highest industrial standards. With a click on a computer mouse Gabriel remote-started one of the two BARD 5.0 prototypes at the Rysumer Nacken test site at noon. The new control centre is one of the world’s most advanced windfarm management facilities. All relevant data of every single wind energy converter can be called off and shown on a display of several square meters size.
              • Offshore suppliers

              • The former oil platform tender, built in Singapore in 1982, was completely overhauled in autumn 2009. There it was outfitted among other things with a crane and a so-called Passive Heeling System for compensating the movement of the vessel e.g. during crane operations. A dynamic positioning system (DPS) acts like an autopilot for the exact positioning at sea. The “MS Natalie” has therefore been updated to state-of-the-art offshore wind farm tender.

            • Projects

            • We want to build a whole series of offshore wind farms in the German Bight. Three farms, each with 80 5-megawatt wind turbines, are planned for the first phase. Approval has already been granted for the ‘BARD Offshore 1’ project. All the wind farms planned by us are a long way from the coast and islands. They will have a total output of at least 3000 megawatts.
                • Offshore

                • The BARD Group offers the turn-key construction of wind farms. The first commercial offshore wind farm in the German part of the North Sea will be ‘BARD Offshore 1’, followed by our already approved project 'Veja Mate' in Germany and three approved BARD offshore windfarms in the Netherlands. Further seven projects in Germany are currently in the process of approval.
                    • BARD Offshore 1

                    • The project area for the ‘BARD Offshore 1’ wind farm in the North Sea is situated about 90 kilometres northwest of the island of Borkum and covers approximately 60 square kilometres. The water is around 40 metres deep. The installation started in March 2010. We will install 80 wind turbines of the ‘BARD 5.0’ type. Since December 2010 the frist converters are connected to the grid. The rated power of the offshore wind power station will be 400 megawatts. TenneT TSO GmbH is responsible for transporting the power to the mainland and for the feeding into the grid. The project is being supported by the European Commission in the framework of the European Energy Programme for Recovery (EEPR) with a grant of 53,1 Mio. EUR
                    • Veja Mate

                    • ‘Veja Mate’ is the second wind farm to realize after “BARD Offshore 1”. The wind farm will be in the west of the German Bight in the southeastern North Sea within Germany’s Exclusive Economic Zone. The site is northwest of the island of Borkum and around 129 kilometres northwest of Helgoland. A total of 80 'BARD 5.0' wind turbines will be installed in an area of 50 square kilometres in 39-41 metres of water. In the east the wind farm borders the ‘BARD Offshore 1’ wind farm.
                  • Onshore

                  • Onshore site locations are important for testing as well as for research and development. Our onshore plants are employed for training our service personnel in preparation for the optimal deployment on our offshore plants which are identical in construction to the onshore plants
                        • Rysumer Nacken

                        • The BARD Group has installed two offshore wind turbines on the area of reclaimed land known as ‘Rysumer Nacken’ at Knock, west of Emden. The wind turbines are the same as those that are used for BARD’s first offshore wind power stations. The aim is to test the whole design intensively under conditions similar to those experienced at sea. The electricity generated will be fed into the general mains supply. In early 2011 the installation of the next generation "BARD 6.5" converters has started.
                    • Nearshore

                    • Testing of technical workflows and of the logistics requires easily accessible site locations on water. Nearshore plants also allow the training of our employees under nearly real conditions.
                          • Hooksiel

                          • In autumn 2008 we installed a ‘BARD 5.0’ test and demonstration wind turbine in the Outer Jade off Hooksiel near Wilhelmshaven. This involved using a ‘BARD Tripile I’ foundation for the first time. The nearshore wind turbine, which has a rated output of 5 megawatts, is level with the Ineos loading jetty about 400 metres from the dyke line. It gave the BARD installation team and the other service providers involved their first opportunity to practice the nitty gritty of working together on assembling the foundation, the wind turbine and its components from the water in real conditions and subject to external influences with a view to subsequent deployment offshore. The energy generated is supplied to gas- und electric power station in Wilhelmshaven via a 20 kV cable.
