A Self-Discharging Ships / Cement Carriers (SDCC) or self-unloader is defined as a vessel that has a bulk material handling system on-board which allows unloading at any terminal with a minimum of receiving facilities.
Our Carlsen brand has been a supplier of self-discharging cement carriers (SDCC) for more than a decade. Our systems have continuously proven themselves extremely reliable and easy to operate and maintain. Hundreds of ships and barges worldwide have been equipped with Carlsen loading and unloading systems.
To meet specific project requirement, we supply both pneumatic and mechanical loading and unloading systems. The unloading capacities may range from 100 TPH for barge unloading systems to over 1200 TPH for large self-unloading ships.
Several materials can be transported and conveyed with Carlsen material handling systems, including powders such as cement, fly ash, barite, bentonite, lime, gypsum, and so on. The dry bulk materials are transferred to the receiving storage facility in the most simple and cost-effective way possible.
The self-unloading ships or SDCC have a dry material handling system which allows them to discharge independently of any harbour, side loading or unloading systems, and to keep control over loading and unloading logistics in any weather conditions.
Airslide Loading System
Air slide loading systems use a slope that harnesses gravity to convey fine powders. This is achieved by forcing air through a porous fabric for the required fluidization.
Screw Conveyor Loading System
The Carlsen screw conveyor (or auger) loading system features sufficient design versatility to accommodate loading applications in almost any industry.
Double Re-Loader System
The double re-loader system uses a set of vacuum pressure tanks to pneumatically discharge the vessel. Using two tanks in tandem allows for a nearly continuous flow.
Screw Conveyor System
The screw conveyor system for self-discharging cement carriers uses screw conveyors to transport dry material to and from the holds. The installation of compressors and pressure tanks also enables pneumatic discharging.
Screw Pump System
The screw conveyor system for self-discharging cement carriers uses screw pumps to transport dry material from the holds to the silo. The installation of compressors and the screw pumps enables pneumatic discharging.
The E3-Cargo System uses a minimum of components to transport cement to and from the cargo holds. This makes the system energy-saving, efficient and economical.
