AVIC Shipyard in Weihai, China, has delivered Multipurpose Vessel Daniel Bernoulli, the sister vessel of the Adhémar de Saint-Venant, to Jan De Nul Group.
Both vessels will be provided with Dynamic Positioning (DP2), a fully diesel-electric machinery arrangement, a comfortable accommodation for 60 persons and a SPS notation.
While in the Subsea Rock Installation mode, the vessels will be able to 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.
The second newbuild, Adhémar de Saint-Venant, will also be delivered to JDN in the coming period, after which they will both be sent off to their first job: one for rock installation works in Denmark, the other as trenching vessel in the Persian Gulf.
