An articulated boom can spread cargo over a wide area. Here, a CSL International Pool vessel unloads coal at Salem, MA (USA). 

By placing cargo where it is needed, CSL self-unloaders reduce port congestion and demurrage costs because they:

• Eliminate many time-consuming steps in the handling process
• Eliminate need for cleanup
• Discharge much faster than conventional dry bulk carriers
• Reduce turnaround time by freeing up congested berths, reducing port costs and demurrage while providing more cargo in a shorter time
