Jan De Nul Group
Services
Jan De Nul Group provides services related to the installation of offshore wind farms, including installation of export and inter array cables, fabrication and installation of gravity based foundations, transport and installation of jacket or monopile foundations and high voltage stations, installation of scour protection around the foundations, and installation of the entire wind turbines itself.
Fleet
Through a constant pursuit of quality and technical innovation, Jan De Nul Group has a very modern and wellbalanced marine fleet for all stages involved in the seabed preparation, wind farm installation and ballasting of the structure, as well as in cable and umbilical installation.
The company owns two jack-up vessels Vole au vent and Taillevent that were especially built to install offshore wind farms. The large cargo deck space and payload, and the lifting capacity of their on-board cranes enable swift and safe installation of the heaviest foundations and other components of offshore wind parks.
Both vessels are 140 metres long. The Vole au vent is equipped with a 1,500 tonnes crane and four spuds to lift itself above the sea level for stable working conditions. She can install all kinds of foundations, as well as the latest generation of wind turbines, in water depths up to 50 metre. The Taillevent has a 1,000 tonnes crane, six spuds and a maximum working depth up to 40 metre. The Group also disposes of versatile and most efficient multipurpose vessels and in-house designed trenching tools to overcome unnavigable tidal areas. These multipurpose vessels can be deployed on a variety of projects: installing subsea cables, trench dredging and subsea rock installation, which definitely makes those vessels unique. The multipurpose vessel Isaac Newton in cable-installation mode for instance is able of transporting and laying cable in one single length with a total weight of approximately 10,500 tonnes.
Jan De Nul Group continues investing in its fleet. Beginning 2017, two new multipurpose vessels were delivered: Adhémar de Saint-Venant and Daniel Bernoulli. The construction of multipurpose vessels allows Jan De Nul Group to better meet the clients’ requests offshore wind turbines in the world. to have a project executed by one contractor of one vessel and to reduce the mobilisation costs for its clients.
