Jan De Nul said in its latest announcement that their new multipurpose vessel Adhémar de Saint-Venant has successfully completed sea trials on the Yellow Sea.

AVIC Shipyard from Weihai, China, launched this new multipurpose vessel for Jan De Nul Group in February.

“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,” Jan De Nul said.

The other JDN’s new multipurpose vessel Daniel Bernoulli, the sister vessel of the Adhémar de Saint-Venant, was launched also in the AVIC Shipyard on April 28.

The vessels will also be provided with Dynamic Positioning (DP2), a fully diesel-electric machinery arrangement, a comfortable accommodation for 60 persons and a SPS notation.

In the Subsea Rock Installation mode, the vessels can install about 5,100 ton of rock in a single load by means of the excavator, conveyor belt and the fall pipe for accurate rock installation at up to 600 m water depth.

Alternatively the rock can be handled through an inclined fall pipe, for secure installation against offshore structures such as jacket platforms, gravity bases or monopile foundations.
