During the construction of the new harbor section at the Port of Lindø in Munkebo, Denmark, large stones and clayey soil made it difficult to set the sheet piles. These were severely damaged during driving and there were many sheet pile lock cracks. read more »

Mining activities are in decline, and not only in Germany. Mines are being closed down all over the world. But what exactly happens to the tunnels, galleries and shafts? Occasionally, stories surface in the press about abrupt subsidence or, as recently happened in France, the flooding of cellars in houses located in a valley in a former mining region. In March 2004, Nordseetaucher was contracted by INSERBAT of Forbach, France, to investigate the cause of the increasing water pressure in the vicinity of a decommissioned mine. read more »
Geotextiles are commonly used as cost-effective construction materials in hydraulic engineering. Over the past decades, woven and non-woven textiles, geogrids and composite materials have emerged to play a key role in canal and waterway engineering, the construction of man-made lakes, barrage engineering and coastal protection. They perform a wide range of tasks, including separation, filtration, drainage, protection, packaging, reinforcement and sealing. read more »
The 7,500 tdw floating dock at the Schichau Seebeck shipyard in Bremerhaven was built in 1964; due to the gradual closure of shipyards it had not been used for many years. In 1986 the dock was lengthened by 30 metres and widened by 6.6 metres, meaning that it no longer fitted through the Fishing Port lock. The dock was put up for sale and a buyer was found. The challenge faced by the engineering firm contracted to arrange the handover was to establish the exact cutting procedure for the longitudinal bisection to enable the dock to be moved. Nordseetaucher was contracted to carry out all cutting work above and below water. read more »
Nordseetaucher was contracted by Hochtief AG, through their Civil Engineering and Construction North office, to assist on the "Schleibrücke Kappeln" bridge-building project. For the very first time, load-bearing seams were welded under water with an a-dimension of up to 10 mm. read more »
The Seeschleuse Leer consortium, which consisted of Bitek Bergungsdienst GmbH and Nordseetaucher GmbH, won a contract in 2001 to renew the slide rails at the Leer sea lock. read more »
A few months ago, we received an enquiry whether it would be possible to clear a mine shaft underwater, build a steel platform and then a cement bridge, and if it was feasible, what tools and materials would we need. read more »
