Butendiek OWF

Boskalis was contracted by OWP Butendiek GmbH & Co. KG to supply, install and protect (by post-lay burial) the high-voltage inter-array cable at the offshore wind farm of Butendiek. This German wind farm is situated in the German Bight (Nordsea), approx. 35 km west of the island of Sylt. The 33 km2 wind farm consists of 80 wind turbines with a capacity of 3.6 MW each and a total capacity of 288 MW. The inauguration of the wind farm took place on September 8, 2015. It provides renew-able energy to approx. 370,000 households.

The infield cables were loaded in one load-out at Drammen in Norway and then cut down to the correct size on site. The WTGs were connected in a grid of infield cables. 86 individual cables were installed between the turbines, including 6 redundancy cables, amounting to a total length of approximately 90 km for the infield cabling. Cable production commenced in December 2013. The cables were installed in the summer of 2014 using the Stemat Spirit. This vessel was converted to enable the handling of the long cable protection system lengths. Trenching of the cables was performed using a separate trenching spread. Termination, testing and commissioning of the 12 cable strings were carried out using in-house resources.

Coastal protection, St. Petersburg

St. Petersburg is a UNESCO World Heritage City, but its location along the River Neva means that it has been threatened by over 300 floods since its founding by Peter the Great in 1703. The completion of the new 25 km long storm-surge barrier across the Gulf of Finland ensures that the city will no longer be vulnerable to high tides and devastating floods. As a result of the new Flood Protection Barrier, however, the old winding access channel had to be replaced with a new, straighter, more easily navigable channel.

Cleanup, Zellingwijk area

The Zellingwijk quarter of the village of Gouderak was built in the middle of the last century. In the early 1980s it became clear that the soil underneath this residential area was heavily contaminated as a result of the dumping of waste - mainly mineral oils and pesticides. The homes built on the site were subsequently demolished in the mid-1980s. Pending definitive remediation work, a layer of concrete / asphalt was applied to seal the site.

Port expansion, Gijón

The Spanish port of Gijón on the Bay of Biscay processes more than 12 million tonnes of bulk goods annually. With the expansion of global trade and increasing ship sizes, the terminal was lacking capacity to handle the traffic. The maximum draft for the ships of 18 meters is another obstacle to the development of the port. So the Port Authority of Gijón developed a plan for additional modern facilities in an area measuring 145 hectares to the north of the existing port. This includes a bulk terminal with a transfer capacity of more than 25 million tons and a storage area measuring 60 hectares for a maximum of 2 million tons of coal and iron ore a year.
