  3. MissionStatement Determine and demonstrate how cable tray technologies can be integrated into ship design to expedite cable installation, reduce safety incidents, and improve first timequality Refer to Title Page for DistributionStatement

  4. ProjectParticipants • BIW • Dave Breton – Project TechnicalLead • Alex Herbert • ATI • Nick Laney – BusinessManager • NASSCO • Paul Hengst –TPOC • HII • Jason Farmer –PTR • Laboratory • TBD • NAVSEA • ChristopherNemarich Refer to Title Page for DistributionStatement

  5. Primary Activity List CompletionSummary • Collect cable installation data – 40%complete • Assess cable tray products – 20%complete • Design demonstrator units – 10%complete • Construct demonstrator units – 0%complete • Conduct a pilot demonstration of a cable tray installation and corresponding cable installation – 0%complete • Conduct time study by measuring the performance of a cable installation – 0% complete • Conduct demonstrator shock testing – 0%complete • Perform a cost benefit assessment – 0%complete • Recommend a technology transition plan – 0%complete Refer to Title Page for DistributionStatement

  6. Advantages/Challenges • Advantages • Install cable tray with other infrastructure; come back to install cable (minimal access issue) • Easier to make changes to cableinstall • May offer protection tocables • Challenges • Weight • Space • Product qualification (needs to bedefined) • Watertight bulkhead interfaces may take the place of traditional transit blocksystems • Increases options for cables and conductor installation (may not need water blocked cable) https://www.google.com/search?q=shipboard+composite+cable+tray&tbm=isch&tbo=u&source=univ&s a=X&ved=2ahUKEwjk4rfFpITfAhUvw1kKHQjtDWMQsAR6BAgAEAE&biw=1347&bih=900#imgrc=QVqBYtKU dtpldM:&spf=1543861988628 Refer to Title Page for DistributionStatement
