AVIC shipyard in Weihai, China launched Jan De Nul
Group's new multipurpose vessel Adhémar de Saint-Venant. The
sister vessel, Daniel Bernoulli, will be launched in March 2017.

To perform a variety of functions, different mission equipment is
available and can be installed on the vessels: subsea rock
installation through an inclined fall pipe or a flexible fall
pipe; subsea trenching, installation of cables and umbilicals;
installation works by means of a heave compensated crane etc ...
This definitely makes them unique.

To safely and efficiently perform these functions the vessels are
provided with Dynamic Positioning (DP2), a fully diesel-electric
machinery arrangement, a comfortable accommodation for 60 persons
and a SPS notation. The Adhémar de Saint-Venant has a
'STRENGTHBOTTOM' class notation; this allows the vessel to be
beached, enabling e.g. cable installation works in very shallow

Over the past eight years Jan De Nul Group has considerably
expanded its fleet and as a result the group now owns the most
state-of-the-art dredging fleet in the world. Nowadays Jan De Nul
Group is adjusting its investment strategy and is now more than
ever focusing on niche markets. The construction of multipurpose
vessels allows Jan De Nul to better meet the clients' requests to
have a project executed by one contractor or one vessel and to
reduce the mobilization costs for its clients.
