Quite a lot of robots crawling in, on and under a decommissioned U.S. Navy destroyer, in addition to alternative elements being additively manufactured on web site, comprised only a small a part of the exercise that happened in the course of the first-ever U.S. Navy Restore Know-how Train, or REPTX, held Aug. 22-Sept. 1 at Naval Base Ventura County (NBVC) in Ventura County, California. Groups from numerous firms in addition to educational and authorities laboratories arrived from all over the world with their expertise purposes to conduct demonstrations and area experiments aboard the decommissioned Spruance-class destroyer, referred to as the Self Protection Check Ship (SDTS). The ship is operated by personnel from Naval Floor Warfare Middle, Port Hueneme Division (NSWC PHD) in Port Hueneme, California, a area exercise of Naval Sea Methods Command (NAVSEA) and positioned at NBVC. NAVSEA’s Naval Methods Engineering and Logistics Directorate Know-how Workplace (NAVSEA 05T) sponsored REPTX 2022, which was hosted by NSWC PHD and held each pierside and aboard the SDTS, which took to the ocean for the second week of the occasion.
“Our priorities as a warfare middle are to ship and maintain readiness, modernize and preserve the present fleet, and area the floor fleet of the long run,” stated Capt. Andrew Hoffman, NSWC PHD commanding officer. “REPTX demonstrates these priorities by permitting each business, authorities and academia to work side-by-side whereas exploring modern upkeep ideas that we are able to quickly ship to our forward-deployed warfighters.”

“The format offers a practical fielding surroundings, each pierside and underway, permitting groups the possibility to area, modify, study and retest their options,” stated Janice Bryant, sustainment expertise program supervisor at NAVSEA 05T.
“REPTX didn’t simply showcase expertise however utilized it to unravel Navy challenges,” Bryant added. “It was a problem-centric occasion that promoted collaboration quite than competitors. Many issues require a posh answer, and a number of individuals have impartial items of that answer.”
The aim of the inaugural train was to see if the expertise can sort out real-world fleet upkeep and battle-damage associated repairs of ships whereas working in a real maritime surroundings — boosting the Navy’s skill to maintain ships at sea by aiding sailors in finishing up wanted repairs. The greater than 60 REPTX individuals demonstrated applied sciences designed to handle 4 focus areas: visualization, command and management aids, ahead manufacturing and expeditionary upkeep. The expertise additionally wanted to be able to taking over a “day job” — in different phrases, serving a function that provides worth to Navy ships and crew on a routine foundation. And, it needs to be user-friendly sufficient for a ship’s crew to study rapidly. Roughly 20 reservists from the Navy’s Surge Upkeep (SurgeMain) program offered that ship’s crew perspective as they bought hands-on with a lot of the expertise, studying learn how to function the remote-controlled robotics, carrying augmented actuality (AR) headsets to view restore directions and movies, measuring corrosion on the deckplate of the SDTS, and extra.
Situations the place reservists had been in a position to remotely management robots included figuring out unknown objects on the aspect of the ship’s hull, detangling a fouled propeller, measuring the depth of steel wastage resulting from corrosion utilizing ultrasonic waves, and inspecting tight areas that may be tough or harmful for a human to enter. A number of firms introduced AR expertise to the SDTS, offering each communication and real-time visuals throughout simulated battle harm evaluation eventualities in addition to restore work directions and movies that may be considered by the headset whereas concurrently trying on the broken space. Additive manufacturing expertise put in in compact transport containers each pierside and aboard the SDTS offered the aptitude to 3D print alternative elements as wanted in quite a lot of supplies. Different eventualities concerned ship-to-shore communication techniques, inspection and restore instruments, and above- and below-water visualization units.

Know-how suppliers assisted SurgeMain reservists in utilizing and demonstrating the expertise aboard the SDTS throughout week two — this time in a real maritime surroundings because the vessel went underway off the coast of Port Hueneme. Unmanned aerial car (UAV) operators bought an opportunity to fly their camera-equipped drones across the ship to examine it. The principle objectives of the UAV demonstrations throughout REPTX had been to establish points like corrosion and misplaced gadgets and to check the UAVs’ capabilities to assist in battle harm evaluation and restore — a key focus space for the Navy — by quickly creating digital fashions, amongst different issues. In a single state of affairs, a flange with a leaky gasket was the main focus of a collaborative effort on the final underway day of REPTX. The SDTS crew had recognized the difficulty within the ship’s state room, and several other expertise suppliers labored on a repair with SurgeMain sailors. A reservist used an AR headset in the course of the state of affairs to attach remotely with a subject knowledgeable elsewhere to assist examine and measure the defective flange.
Armed with measurements of the flange meeting, two additive manufacturing firms collaborating in REPTX later 3D-printed elements that could possibly be used to interchange the flange and gasket within the state room. Different underway demonstrations examined, repaired and monitored very important tools on the ship. Contributors and organizers agreed that a number of the greatest issues to return out of REPTX had been the spontaneous collaborations between attending organizations that exposed extra environment friendly makes use of of their particular person applied sciences when used collectively. Together with the give attention to collaboration, organizers designed the occasion to be instructional for everybody concerned. The educational expertise was impactful in that it was arms on, operationally based mostly and held aboard an energetic ship. Bryant stated that subsequent steps embody figuring out learn how to make investments $2 million in follow-on funding to additional develop applied sciences for fielding within the fleet. The REPTX crew will even launch to the general public a complete after motion report on the occasion.
