Boskalis HIRDES

Heinrich Hirdes was a pioneer in German hydraulic construction and founded his company in 1912 with a focus on hydraulic construction and dredging. In the 1950s, it expanded to include coastal protection, shipping channel development and maintenance on the coast and land reclamation. The pioneering spirit and passion for these specific engineering areas are still a part of the corporate culture. Alongside efficiency and quality, even today the subjects of sustainability, safety and environmental protection drive our actions and the further development of technology and processes. Even the specific demands in sensitive areas, such as conservation areas and national parks are always fulfilled by us when realising projects.


Heinrich Hirdes GmbH has belonged to the Royal Boskalis Westminster N.V. Group since 1991, a globally leading maritime services provider for dredging work and infrastructure, offshore services for oil, gas, as well as renewable energies and salvage work. Different specialist providers from the above service areas combine in the Boskalis Group and supplement each other with technical knowledge, experts and specialist technology. In the Boskalis Group we share our commitment to quality, sustainability, environmental protection and expand our spectrum of knowledge and technology. For this reason, we are also proud to carry the name Boskalis HIRDES, under which we combine the three business divisions of Heinrich Hirdes:


Heinrich Hirdes GmbH

Heinrich Hirdes GmbH is responsible for the entire area of dredging and hydraulic construction, including coastal protection and environmental engineering. With locations in Hamburg, Bremen and Rostock we are represented along the entire German coast and are always close to our customers.


Heinrich Hirdes Kampfmittelräumung GmbH

As a hydraulic construction company, we recognised the danger of legacy ordnance early on and built up our expertise in this area. Because of the increasing demand for sounding and salvaging ordnance as well as because of the experience gained since 1978 in this area, we founded Heinrich Hirdes Kampfmittelräumung GmbH as an independent company. Ordnance experts, analysts, safety experts, planners and specialist administrative experts are ready at the locations in Hamburg and Teltow for deployment throughout Germany.

Heinrich Hirdes EOD Services GmbH

The conditions for locating and recovering ordnance in the coastal area or onshore differ strongly from those on the high seas. What was originally considered to be a separate group of experts lead to the founding in 2012 of the independent Heinrich Hirdes EOD Services GmbH, which deals specifically with locating and recovering ordnance on the seabed. Our locations are in Hamburg and Fareham (UK) – the deployment locations around the world.


Innovation and promotion of new talent

As an innovative company, we also see ourselves obliged to work outside our operative core business. For example, we cooperate in numerous expert panels in the creation of new future solutions in hydraulic construction and in ordnance clearance and commit to promoting new talent through cooperation with higher education institutions and universities. We contribute our experience from international projects and participate actively in the further development of work processes and their technical solutions.

Social commitment

We are especially proud of the fact that it is not just us as a company that feels a social responsibility – our employees also show great commitment when their social environment involves shipping or other charitable projects. We would therefore like to emphasise some of our commitments here.

  • Since 1992 we have been supporting the Technische Denkmal Forst- und Köhlerhof Rostock-Wiethagen
  • We have been a supporter of the Deutsche Meeresmuseum Stralsund for many years
  • For the school year 2020-2021, we have adopted a reading partnership with the German department of the Heisenberg-Gymnasium Hamburg-Harburg.

  • In addition, we also support other social, civic projects. During the Christmas party our colleagues donated Euro 7,500.00 to charity. The donated amount was shared between the following organisations:
    • German Maritime Search and Rescue Service (Euro 3,000.00)
    • German Seamen's Mission (Euro 750.00)
    • Hände für Kinder e.V. (Euro 3,750.00)
