The M/V John A.B. Dillard, Jr. is a Debris Removal Vessel for the U.S. Army Corps of Engineers (USACE) San Francisco Bay District. The District has a unique mix of duties, including keeping the navigation and shipping lanes of the greater San Francisco Bay region free of floating debris hazardous to marine vessels. This vessel allows shorter response times, increased capacity and greater range. Key to this enhanced capability is the large aft deck, pedestal mounted grapple crane and robust 15 ton deck load capacity. Operators are able to recover large heavy objects in a single “grab” rather than the hazardous and time consuming process of towing objects to base.
