Although trailing suction hopper dredgers and cutter suction dredgers are the core of a dredging fleet; however, assistance from other sources is required to execute dredging works. This assistance comes as a small fleet of floating auxiliary equipment such as tugboats, multicats, crew vessels, survey vessels and pontoons.
The importance of the auxiliary vessels cannot be underestimated. For instance, in some cases the anchors of a cutter suction dredger must be placed by means of a multicat. A floating pipeline must be anchored using anchors and pontoons. Otherwise, waves and currents may damage and or break the pipeline. The auxiliary vessels help minimise downtime by ferrying crew members, spare parts, fuel and lubricants quickly and efficiently to the dredger.
These auxiliary vessels are not only deployed on dredging projects, but also on civil and environmental projects.
