It is not self-propelled. Has twin variable speed slurry pumps installed in series, often saving the need for installation of a booster pump into the discharge pipeline.
The vessel was completely re-fitted in 2014 during which the whole power system, electrical system, positioning system and the hydraulic systems were completely exchanged with the latest in in technologies.
Other upgrades were done to the engine room, filtration systems, exhausts (changed to water cooled), floating lines, keel coolers and others.
The quietness of this dredge allows it to work in sensitive areas.
