Side stone dumping vessels are self-propelled vessels that are typically used for scour protection for offshore wind turbines and offshore rigs, the construction of breakwaters, and subsea pipeline protection. The vessels are capable of transporting and installing a wide variety of different sizes of rock, varying from gravel to rocks weighing up to 800 kg.
A side stone dumping vessel has worked on the construction of a 2,200-m-long breakwater. The construction is part of a new container terminal in Costa Rica, which will boost the Costa Rican economy. Read about this project in progress in our magazine.
Van Oord has 2 side stone dumping vessels in its fleet:
- HAM 602

The Jan Steen is a multipurpose construction vessel. It is suitable for deployment on a variety of tasks, such as side stone dumping, rock installation by flexible fallpipe and diving support activities. The vessel is fully self-supporting, has accommodations for 45 persons, and a maximum loading capacity of 1,750 tonnes.
