Boocock, Simon K. | Harris, Joe | Appleman, Bernard R.
This report describes how the NSRP Project 3-94-2, Combined Abrasive Recycling & Containment System, was conducted. The report includes brief descriptions of preliminary tasks involving information retrieval and the selection of a combined abrasive recycling and containment unit suited for shipyard use. The bulk of this report describes the construction of a prototype of the combined abrasive recycling and containment unit. The containment unit was evaluated at Atlantic Marine in Jacksonville, Florida. Details are given of the evaluation and analysis of results from this prototype demonstration. Based on the results of the demonstration, a redesign of the containment unit was developed that incorporates many improvements. From several alternatives the research team selected a mini-enclosure containment system. It used a commercially available rigid space frame construction fitted with waste collection hoppers and aluminum gratings for the working platform. The enclosure gained access to the ship hull from a truck mounted lifting arm. The platform had a 12-foot reach and approximately 125-degree yaw capability. The containment membrane and seals were designed to create a class 1A containment (highest degree of emission control). This required an engineered ventilation system to provide adequate air movement within the enclosure.
