  3-D Scanning Technology Makes Splash at NNSY Thanks to Partnership with Puget Sound

  By Kristi Britt, Public Affairs Specialist, PORTSMOUTH, Va (NNS) -- Although they have only worked at Norfolk Naval Shipyard (NNSY) for less than 10 months, two employees are already involved in the future of innovative technologies in America's Shipyard. Code 268 Engineering Technician Jason Ewick and Code 2340 Assist Shift Test Engineer (ASTE) Joey Hoellerich were brought into the NNSY Technology and Innovation (T&I) Lab, a group dedicated to bringing the real ideas and technologies of the shipyard to the forefront. With their arrival to the team, both were given the unique opportunity to share knowledge with Puget Sound Naval Shipyard and Intermediate Maintenance Facility (PSNS&IMF), using laser scanning to provide accurate measurements for shipboard work. “The USS Dwight D. Eisenhower (CVN 69) was at NNSY in years past, Naval Air Systems Command (NAVAIR) brought Puget Sound representatives to our shipyard to use their laser scanning technology to cut off all added material from four sponsons onboard the vessel,” said NNSY T&I Lab Lead Dan Adams. Sponsons are the projections extending from both sides of the watercraft to provide protection, stability, mounting locations, etc. “During the time, we observed the process and wanted to learn what we could from our sister shipyard team.” The team from PSNS&IMF returned to NNSY to give guidance on the process, with Code 290 representative Dan Hager, and Shop 11 Mold Loft representatives Jason Anderson and Jeremiah Swain taking charge in sharing what they knew to Ewick and Hoellerich. “The team from Puget was absolutely amazing and shared the ins and outs of the 3-D scanning technology with us,” said Ewick. “I had done laser scanning work in the private industry but it was my first time tackling something like this. Hager, Anderson, and Swain guided us through each step, sharing as much knowledge as they could with us about two different processes we could use to get the results we needed.” The first process is photogrammetry, where you place targets an inch apart on a desired object or space for scanning. Once complete, you take multiple photographs which are then compiled into a software to build the 3-D model. The second process is the 3-D laser scanning, which requires more space for a larger read. The targets would be placed and then someone would operate the laser tracker and scanner from the pier to get the scan needed. Once completed, the 3-D model would be compiled in the software for use. With the knowledge provided by PSNS&IMF and USS George H.W. Bush (CVN 77) in drydock, Ewick and Hoellerich were ready to tackle the process for NNSY. “We began at Colonna's Shipyard in Norfolk where the sponsons are being produced,” said Ewick. “We use the scanning technology to analyze where the sponson would meet the shell of the ship. It helps provide an accurate measurement for our workers when it comes to installation and repair.” Next up was scanning after the pieces were installed. At this time three of the four sponsons have been installed onboard the Bush. “The two forward sponsons were scanned using photogrammetry,” said Ewick. “It was a first for us and required coordination across various shops and codes throughout the shipyard.” The Pipefitter Shop (Shop 56), The Optical Diesel Mechanics (Shop 38), the Shipfitter Shop (Shop 11), the Shipyard Operations Department (Code 300), and partners at Puget all played a part in this evolution. “It was a collaborative effort and we were able to be successful thanks to our shipyard family coming together to make it happen.” This process was a first for NNSY and a first for using the software directly in the drydock instead from piers and barges. “It's amazing to see something come together like this, especially when you think that we were two blank slates coming into the project,” said Hoellerich who had no prior experience working with 3-D scanning and metrology before joining the lab. “We were able to partner with our sister shipyard and work with shops and codes that I never thought I'd be able to do when I first joined the ranks of NNSY. Being able to gain that knowledge from our shipyard family and utilize what we've learned in the field is something those of us working in innovation live for.” The team will be completing the rear scans for the Bush in the future and hope to continue to perfect the process. In addition, they hope to continue to work with other shipyard entities to further expand on the technologies of the future. “This partnership has been a major success for us and we hope to continue to build those relationships with the other shipyards and beyond,” said Hoellerich. “We can all learn from each other and build from each other's experiences. We all share a mission and together we can succeed.” Ewick added, “we've also begun expanding more ways we can use the scanning technology at our shipyard. For example, we are looking into a future project where we scan inside the ship and build a path for extracting heavy equipment from within as to avoid interferences. We've seen more interest from others within the shipyard since we began to do work with this technology, seeing what ways it could help improve what we do here. That's what innovation is all about, taking those first steps in seeing what works. Even if what you try doesn't pan out, at least you gave it a shot. But you'll never know if it works or not unless you take that step. Don't be scared to try out something new.” For more information regarding innovation, contact the NNSY T&I Lab at 757-396-7180 or email the REAL Ideas program at NNSY_REALIdeas@navy.mil. https://www.navy.mil/submit/display.asp?story_id=110422

  Change of plans: Seoul decides to start from scratch with helo competition

  By: Jeff Jeong SEOUL — It looked like Italy's aerospace group Leonardo was going to be an easy winner for South Korea's second batch of anti-submarine helicopters. The procurement program would seek 12 more AW-159 “Wildcat” helicopters, with no other competitors for the $840 million program. But the Defense Acquisition Program Administration, or DAPA, threw a curveball, deciding to accept a U.S. proposal for alternate option and to begin the competitive bidding process from the scratch. The plan for the maritime operational helicopter, or MOH, was originally to sign a direct commercial deal with a foreign helicopter maker, with three bidders — Leonardo, Lockheed Martin and NH Industries — showing interest. The two latter contenders failed to submit their proposals by the Oct. 31 deadline, leaving Leonardo seemingly as the only remaining bidder. According to sources from DAPA, however, the U.S. government in November sent a letter of price and availability of Lockheed Martin's MH-60R Seahawk, causing South Korea's arms procurement officials o rethink the acquisition approach. “We've decided to consider the U.S. FMS option,” DAPA spokesman Park Jung-eun told Defense News. “We're going to weigh in on both options of commercial and FMS contracts.” As dictated by acquisition regulation, two successive failed biddings mean that the agency can make a private contract with a sole bidder, but that's not mandatory. The agency is expected to issue a renewed request for proposals as early as March, according to DAPA officials. Leonardo would be a direct buy, while the Sikorsky bid would be a foreign military sale. Leonardo said in a statement that it would still pursue the South Korean naval helicopter program “in a fair and transparent manner.” A Leonardo spokesman said the AW-159 is optimized for the Korean theater of operations, pointing to an active electronically scanned array (AESA) radar for detecting North Korea's coastal weapon system and a missile firing range that is more than three times longer than Seahawk. “We do not really know about the details of the U.S. Navy's latest proposal,” a Lockheed Martin communications official said, declining to elaborate. “After an RFP is issued, we could be able to discuss with the service.” Pundits here expressed different reactions to the renewed MOH bidding process. Shin In-kyun, head of Korea Defense Network, a Seoul-based private defense think tank, said it's a better opportunity to acquire state-of-the-art naval helicopters with better performances. “The Seahawk is estimated to be more expensive by 20 to 30 percent than the Wildcat, but the former has performances about two times better than the latter,” said Shin. “The unit price of the MH-60R could be lowered through the FMS, as the U.S. and Indian Navies are also said to be procuring more than 40 MH-60Rs.” Shin Jong-woo, a senior analyst at the Korea Defense & Security Forum, said an FMS deal may not guarantee economic benefit for South Korea. “You give up offset programs should an FMS deal be made,” he said. “I'm not really sure how much the unit cost of the MH-60R could be lowered. If lowered, we may have to lose some optional functions of the helicopter.” Moreover, a possible MH-60R selection will bring more work to change the designs of warships, he added. “The Navy's existing warships, including the KDX-III Aegis destroyer, are not able to accommodate the MH-60R, so it's inevitable to change the design should the American helicopter be chosen.” The South Korean Navy currently operates eight AW-159s acquired under a 2012 deal. The helicopters fly missions aboard KDX-series destroyers and Incheon-class guided-missile frigates. The service plans to commission at least 12 more new frigates fitted with a flight deck and a hangar that can accommodate one Lynx helicopter. https://www.defensenews.com/2019/01/23/change-of-plans-seoul-decides-to-start-from-scratch-with-helo-competition
