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.

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.

Port development, Sevilla

Seville is located 80 km land inwards and it is Spain’s only commercial river port. Access is along the Rio Guadalquivir. The current dimensions and depth of the port impose limitations on the breadth and draughts of the vessels that use it, putting the future of the port at risk. So the Port Authority developed a New Maritime Approach that provides for the deepening and widening of the approaches to the port.
