Performing surface maintenance on submarine and aircraft carrier bilges and tanks is often done in hazardous environments, exposing workers to multiple safety hazards. The Navy Metalworking Center (NMC) is working with Norfolk Naval Shipyard (NNSY), International Climbing Machines, NAVSEA 04, NAVSEA 05, and the other naval shipyards on a solution that will save money and improve worker safety. The project will modify an existing, remotely operated crawler to perform a wide variety of inspection, de-coating, and preservation tasks in hazardous or inaccessible shipboard areas. This project is being funded by the NAVSEA Paint Center of Excellence.

In addition to challenges posed by potentially toxic atmospheres, some of the surfaces are physically inaccessible to the average shipyard worker. In order to reach these locations, shipyards must remove a significant amount of piping or equipment, causing additional work and cost.

Use of a remotely operated crawler can reduce labor and personnel exposure by 80 percent and can eliminate the labor needed to remove interference to allow human access to the surfaces to be maintained. Total five-year cost savings from the use of this system on two Moored Training Ships maintained by NNSY is expected to be $2.67 million. The modified crawler will be implemented at NNSY in the spring of 2014.
