Bauer celebrates Bauma innovation award win

Development of a new offshore piling technique helped Bauer Spezialtiefbau to win the construction process category at this week’s Bauma Innovation Prize event.

Award of the prize to Bauer was announced during the opening ceremony of the Bauma construction equipment trade show, which was held in Munich this week.

Bauer engineer Paul Scheller accepted the award on behalf of the successful team.

The company has said that the award is recognition of the joint efforts of Bauer’s construction and equipment divisions to develop an entirely new underwater drilling rig through in just a few months.

The system was developed to sink a pile into the sea bed as the foundation base for a tidal turbine in the North Sea, close to the Orkney Islands.

The new-style drilling rig was lowered to the sea bed from a special ship but the rig could only be used in calm tidal conditions, limiting work to an hour between the turn of the tide. Multiple drive units held the ship in position with the aid of GPS to allow the drilling, which was carried out using a roller bit and torque provided by a BG 28 rotary drive, to be carried out accurately. The system successfully enabled Bauer to construct a 23m long, 2m diameter mono pile with an 11m rock socket in 37m deep water to support the 1MW turbine.
