The HOCHTIEF jack-up platform Thor is one of the biggest platforms for installing wind energy facilities offshore. It can set up wind energy facilities of the latest generation. The fixed 500-ton crane has been designed for safe and efficient work from the sea.

Thor is being given its legs. These are 82 meters long and enable set-up in water depths of up to 50 meters. Each weighs 550 tons. The jack-up platform, on which a 500-ton crane has been installed, also offers accommodation for 48 people.

The HOCHTIEF jack-up platform Odin at the transformer station for the alpha ventus wind farm, 45 kilometers off the island of Borkum. For Germany's first offshore wind farm, Odin anchored the entire multi-element structure in the sea bed at a water depth of more than 30 meters.

The jack-up platform Odin was also used for installing six of the twelve wind energy facilities for the alpha ventus wind farm. Since its conversion in 2009, Odin features a 300-ton crane and offers accommodation units for 40 people.

Known as Barwa Commercial Avenue, the project will comprise retail, office and residential units. It is being created beside the urban highway on the southern outskirts of Doha and will have a gross floor area of close on 900,000 square meters – equivalent to around 110 soccer pitches.

Up to 7000 people will work at Barwa Commercial Avenue in peak periods.

"Commercial Avenue is a major success of last year's systematic re-alignment to international growth markets. Here in the Gulf Region, we have plans for further expansion", says Henner Mahlstedt, HOCHTIEF Construction's CEO.
