Along with dredging and offshore oil & gas, offshore wind is one of Van Oord’s three core activities. All activities and knowledge for the construction of offshore wind farms are combined in the Offshore Wind Projects business unit. In more than ten years, Van Oord Offshore Wind Projects has completed several prominent projects as an EPC contractor, being responsible for the engineering, procurement and construction. Innovative solutions contribute significantly to making this form of sustainable energy more competitive. Van Oord and its Marine ingenuity are already meeting this challenge head-on.
In our role as an EPC contractor, we offer our clients the following benefits:
- collaboration on engineering of various designs;
- flexibility in choosing equipment, subcontractors, and suppliers;
- smooth implementation of changes in terms/requirements;
- rapid start and completion;
- risk management;
- a minimum number of interfaces and contracts.
Gemini Offshore Wind Park (2016)
Van Oord is the EPC contractor for the Gemini Offshore Wind Park, one of the largest offshore wind projects in the world. This challenging project consists of the installation of 150 4 MW Siemens wind turbines, which will supply a total of 600 MW of renewable energy to 785,000 households by 2017. With a value of more than EUR 1.3 billion, it’s the largest contract in Van Oord’s history.
The offshore wind park is situated 85 kilometres north of the Dutch province of Groningen. Our activities encompass the supply and installation of the foundations, the entire electrical infrastructure, including the supply and installation of offshore and onshore high voltage stations, inter-array and export cables, and the installation of the Siemens wind turbines.
Windpark Westermeerwind (2016)
Windpark Westermeerwind will be built in the waters of the Dutch lake IJsselmeer, along the dikes of the Noordoostpolder. It will consist of 48 wind turbines of 3 MW - divided into two rows along the Westermeerdijk and one row along the Noordermeerdijk - and a transformer station on the mainland.
In 2013, Van Oord started with the engineering and procurement for the Eneco Luchterduinen wind farm in the Netherlands. The wind farm is constructed 23 kilomteres off the coast of Zandvoort. The wind farm consists of 43 Vestas V112 wind turbines. With a capacity of 129 MW, it supplies green energy to 150,000 households in 2015. Construction of the wind farm started in Spring 2014, and the offshore wind farm was completed in 2015.
The construction of Teesside Offshore Wind Farm off the north coast of England began in January 2012. This is a full balance-of-plant contract for 27 foundations, 18 kilometres of infield cables and the installation of scour protection around the foundations. The 62 MW wind farm became operational in the summer of 2013.
Meteo masts (2011)
In 2011, Van Oord has built two meteo masts as an EPC contractor. These were constructed in the North Sea on schedule in 2011. Both masts are situated approximately 75 kilometres offshore, one off the coast of IJmuiden, Netherlands, and the other off the coast of Cuxhaven, Germany. The masts are used to measure the wind and weather conditions at sea. Sensors track wind speed, wind direction, temperature and changes in air pressure. The information is important for the development of further offshore wind farms in the North Sea.
Prinses Amalia (2008) and Belwind (2012)
Van Oord completed the Prinses Amalia Windpark in 2008. Located off the coast near IJmuiden, it supplies 120,000 households in the Netherlands with sustainable energy. In late 2010, Van Oord completed the Belwind Phase 1 Offshore Wind Farm off the coast of Zeebrugge, Belgium. Belwind 1 has a capacity of 165 MW and supplies green energy to approximately 175,000 Belgian households. Van Oord’s work in both cases consisted of the design, engineering, procurement and construction of the wind farm’s foundations, and the entire electrical infrastructure, such as the export cable, infield cables and offshore high voltage station (OHVS), as well as the installation of the wind turbines. All Balance of Plant activities, meaning all activities related to the construction of a wind farm except for the supply of the turbine, are performed by Van Oord.
Vessels Aeolus and Nexus
To increase and strengthen our position in offshore wind, we have invested in a new offshore installation vessel and a new cable-laying vessel. The Aeolus is 139 metres in length, 38 metres in the beam, and is equipped with a crane that can lift 990 tonnes. The Aeolus is used for the construction of offshore wind farms. The Nexus is 123 metres in length, 28 metres in the beam, and has a 5,000 tonne carousel. The Nexus is used to install the export cables for connecting the wind farms to the onshore electricity grid and connecting the inner array cables between the turbines.
