  3. Learning Objectives Define the JFMM and TRIDENT Refit Facilities requirements for a WAF Familiarization with the references used to properly fill out a WAF How to identify WAF boundaries and work to be accomplished Accurately fill in all applicable blocks on the WAF

  4. Keep This In Mind!! Above all else it must be understood that Work Control is a Safety Program! This must remain fresh in our minds at every step in the process. The fundamentals must be considered sacred

  5. The main purpose of a WAF: To formally control and safely authorize work WAFContract Think of the WAF as a contract between Ship’s Force and the Repair Activity Identifying the scope of work and work boundaries Complete and thorough descriptions are important in developing and verifying proper isolation

  6. TRF Work Control Group S/F Work Control Centralized Work Control Team Repair Activity Ship

  7. For availabilities where a repair activity is assigned responsibility for work authorization control by MOA, the requirement regarding when Ship’s Force must submit a WAF shall be specified in the Work includes all maintenance, repairs or modifications, and MOA. installation or removal of temporary support systems and The repair activity performing the work (or SF) shall prepare the equipment. WAF unless specified otherwise by the MOA signed for that availability. Unless defined by MOA, contractors are responsible for the preparation and submitting the WAF to Ship’s Force. WAF process for routine maintenance Preparation for work A WAF is required to authorize the start of work on all ship systems and equipment.

  8. WAF process for routine maintenance • Joint Fleet Maintenance Manual Requires a WAF for the following: • Planned Maintenance (PMS) • Troubleshooting • Corrective Maintenance • Alterations • Removal of System Components for repairs • Modifications • Installation or removal of temporary support • systems and equipment. Repair activity non-intrusive work (e.g. painting, lagging, Sheet metal work, deck plate, structural foundation) that does not affect ship or personnel safety does not normally require a WAF.

  9. TRF requires a WAF for: • Work which could cause personnel injury or equipment damage if the component or system could be normally operated while work is in progress. • Any work requiring Code 350 review prior to performing work per the Local Nuclear Power Manual, Chapter 2 . • Any work requiring entry into a periscope or mast well while the scope or mast is installed. • Making connections to systems, disconnecting from systems, removal of valves, removal of piping, removal of mechanical components or opening a pressure boundary for authorized work or interference removal. • Cutting or removing foundations from propulsion plant equipment. • Removal of, or work accomplished on non-pressure hull plates (ex. sail plates) ballast tank flood grates, valve strainer plates, framing, or any other components on the external hull of a submarine.

  10. TRF requires a WAF for: • Installation or removal of TRIREFFAC systems to or from ship systems. • Any work which requires the use of divers,for example, installation or removal of adapters, fittings, or other attachments to ship sea valve hull pads. • Removal of electrical cables and amphenols from any components. • Removal of switchboard or other electrical panels for access to install TRIREFFAC temporary electrical services or to perform repair work. • Disconnection of ship's lighting and other electrical fixtures/components • Repairing, troubleshooting and grooming of electrical/electronic equipment. • Entering energized electrical equipment when not specifically identified by test or other working document.

  11. TRF requires a WAF for: • Hot work as defined in NSTM Chapter 074, section 074-10.8.2. • Installation or removal of blanks that will see pressure during normal system operation. • Installation/removal of staging in the area of equipment, that if operated, could cause personnel injury or equipment damage due to interference with the staging (i.e., mast, antennas, fairwater planes, SPU). • Work that affects ships general announcing (1MC) capability for fire alarm announcing purposes. • Work that affects reactor plant containment boundary. • Work requiring the installation of cleanliness plugs or blanks in sanitary tanks and fuel tank systems for any purpose (i.e., sandblasting, tank cleaning/ painting, etc. not already specifically covered in the “scope of work” section of another approved WAF). Ship’s Force, WPC, orEngineering should be contacted to assist in identification of these penetrations if required.

  12. TRF requires a WAF for: • Work requiring the establishment of freeze seals, installation of piping pressure blanks, electrical control system jumpers or other similar safety devices. • Opening access covers for machinery or electrical equipment. • Any work requiring access to internal tanks. • All work, intrusive or non-intrusive, requiring entry into or on the sail by TRIREFFAC employees.

  13. Work typically not requiring a WAF • Preventative maintenance, when integrity of a ship system is not being disturbed (Ship's Force only). • Painting, cleaning or surface preparation for painting (including sandblasting)unless it requires access to an internal tank. • Non-intrusive work inside external tanks (example: painting, inspections) when there is a previously approved WAF to access the tank. • Removal and/or installation of insulation, staging (unless area of equipment, that if operated, could cause personnel injury or equipment damage due to interference with the staging or is within an internal tank), deck coverings, deck plates, ladders, handrails or grabs. • Removal, installation, or alteration of workbenches (not attached to a ship’s system), lockers, non-structural bulkheads, furniture or joiner work.

  14. Work typically not requiring a WAF • Removal, installation or adjustment of label plates, wire way hangers or cable bands unless “hot work” is required. • Installation of temporary systems not connected into ship systems and not installed for the maintenance of ship conditions. • Replacement of fluorescent lamps, regular screw in light bulbs, starters, and bayonet type sight glass light bulbs. • Weapons Systems Office and Electronic Shop shipboard preventative maintenance when conducted in accordance with an approved preventative maintenance instruction that does not require a tag-out. • Entering energized electrical equipment when specifically required by a working test procedure and all appropriate safety precautions are followed.

  15. Work typically not requiring a WAF • Unbolting and reinstallation of electrical components when disconnection or entrance to the component is not required and a temporary ground strap is installed. • Routine diving operations that do not require work to be conducted on the unit. (e.g. security swims, arrival and departure swims etc.)

  16. WAF process for routine maintenance How Does the WAF Get Started? • Non-controlled work – The AWR and associated LTD’s (drawings, maintenance standards etc..) are received in Work Packaging from MDCO and the Tech. Library. The Work Packaging technician assembles the documentation into a work package. • Controlled Work – This work requires a CWP. The AWR, associated LTD’s and required QA forms are assembled by a planner, reviewed by QA and approved by the appropriate department head. A CWP is delivered to Work Packaging by the planner.

  17. WAF process for routine maintenance • The Work Packaging technician reviews the AWR • and determines if a WAF is required. • If a WAF is not required, the technician will stamp • the cover Page of the AWR “NO WAF REQUIRED”. • The Work Package is sent to the LWC. The job is • ready to work. • If a WAF is required, the technician will review the AWR for the scope of work, work boundaries and any precautions and/or restrictions.

  18. WAF process for routine maintenance • The Technician will write the WAF, place it with the • Work Package (or CWP) and route them to the LWC • and AWC(s) (if required). • The LWC shall review the WAF and AWR and sign for • approval of the WAF and, if required, forward to the • AWC(s) for concurrence. • The last work center to approve/concur on the WAF • forwards the WAF and Work Package (CWP) to • Work Control.

  19. WAF process for routine maintenance • The Work Packaging Technician places a “Not a • Working Copy” copy of the WAF with the work • Package,forwards the WAF to Work Control • and delivers the Work Package to the LWC. • CWP’s are filed in Work Packaging until the WAF • has been opened and all required opening signatures • on the QA-9 are made. Then the CWP and WAF are • delivered to the LWC. • A Work Control Technician delivers the WAF to • Ship’s Force to establish ship/system conditions, set • isolation and open the WAF. The Work Control • Technician acts as the Repair Activity Representative.

  20. WAF process for routine maintenance • After the WAF is opened, the Work Control Technician • distributes copies of the WAF as follows: • White (original) – Ship’s Force WAF Log • Yellow Copy - LWC • White Copy(ies) – LWC for distribution to AWCs • Gold Copy - Work Control WAF Log

  21. Tagout Log The Work Authorization Log(s) WAF shall be maintained at the same LOG location as the ship’s tagout logs and administered by the same individuals. WAF process for routine maintenance Preparation for work

  22. WAF process for routine maintenance Preparation for work Administration of the Logs When the repair activity is assigned responsibility for work authorization control by MOA, then the repair activity shall retain original TRF WAFs with a copy of all WAFs and WAF index provided to Ship’s Force. For Ship’s Force and Contractor WAFs, Ship’s Force keeps the original and provides a copy to TRF when they obtain the WAF number. NOTE: When a repair activity is assigned responsibility for work authorization control, that activity will maintain the Work Authorization log and specify the serialization process used by all activities including Ship’s Force for the availability.
