Overview
HEGEMANN GRUPPE (Hegemann Group) is a German industrial and services group headquartered in Bremen. Its parent company is Detlef Hegemann Aktiengesellschaft, which acts as the group holding. The group operates across three main divisions: Construction, Industry and Tourism, and is active beyond its home region in Germany as well as in the Netherlands. The origins of the group lie in the construction sector. In 1914 August Reiners founded the construction firm of the same name in Bremen, specialising in civil engineering works. From 1973 to 2006 the Hegemann Group was led by Detlef Hegemann, the grandson of August Reiners. After the political turnaround in East Germany, the group expanded into the new federal states. In 1992 it acquired the Wolgast-based Peene-Werft and four companies of the ELBO-Bau-Gruppe, which had emerged from former state housing construction combines. Of these four companies only August Reiners Bauunternehmung GmbH still exists today. Until 1994 the group held a 30 percent stake in Stralsund's Volkswerft, which it then sold to Bremer Vulkan. In 2007, as part of a strategic realignment of the group's construction activities, August Reiners Bauunternehmung und Naßbaggerei GmbH Wolgast merged with the Schälerbau Berlin GmbH branches, August Reiners Bauunternehmung GmbH and Alfred Kunz Untertagebau München. In the same year the Hegemann Group took over Stralsunder Volkswerft GmbH from the Danish A. P. Møller-Mærsk group, which was to pass to new owners in 2010. Also in that year Detlef Hegemann Rolandwerft GmbH & Co. KG was sold to the Bremen-based Lürssen group. Today the sole shareholders of the Hegemann Group are the two charitable foundations of Detlef and Ursula Hegemann. The group's Construction division focuses on road, civil and sewer construction, bridge and tunnel construction, and structural and engineering construction. Over time the portfolio has been extended to include industrial piping and plant construction for utilities and industrial companies, as well as building preservation. The division's service offering is complemented by real estate management in project development and real estate marketing. The Industry division covers services in dredging, such as the maintenance of harbours and waterways as well as land reclamation and beach replenishment. Environmental technology activities include solutions for the recycling of residual materials, their dismantling, processing and reuse in other economic sectors. Environmental technology also includes the treatment and immobilisation of water sediments, sludge dewatering and soil mechanical investigations. The group also offers services in steel processing, slag processing and internal coil transport. Its in-house shipyard covers not only the classic profile of an inland shipyard but also innovations in maritime manufacturing. With Stern und Kreisschiffahrt GmbH, a Berlin passenger shipping company belongs to the Tourism business segment. Companies and branches of the Hegemann Group include, in Construction: August Reiners Holding GmbH, Bremen; August Reiners Bauunternehmung GmbH, Bremen; and Detlef Hegemann Immobilien Management GmbH, Bremen. In Industry: Hegemann GmbH, Bremen; Detlef Hegemann GmbH, Bremen; Detlef Hegemann Umwelttechnik GmbH, Bremen; Detlef Hegemann B.V., Winschoten; and Metallverarbeitung GmbH, Groß Plasten. In Tourism: MV Hotel + Touristik GmbH, Rostock; Stern und Kreis Gastronomie und Service GmbH, Berlin; Stern und Kreisschiffahrt GmbH, Berlin; and Stern und Kreis Wassertaxi GmbH, Berlin. Former subsidiaries include Rolandwerft (until June 2010), Volkswerft Stralsund GmbH, Stralsund (July 2007 to June 2010) and Peene-Werft GmbH, Wolgast (until June 2010).
