Learning objectives

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


Keep this in mind

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


Waf contract

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

WAF process for routine maintenance

Preparation for work

A WAF is required to authorize the start of work on all ship systems and equipment.


Training use only

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.


Trf requires a waf for

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.


Trf requires a waf for1

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.

  • 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.


Trf requires a waf for3

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.

  • All work, intrusive or non-intrusive, requiring entry into or on the sail by TRIREFFAC employees.


Work typically not requiring a waf

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.


Work typically not requiring a waf1

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.)


How does the waf get started

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.


Waf process for routine maintenance

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.


Waf process for routine maintenance1

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.


Waf process for routine maintenance2

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.


Waf process for routine maintenance3

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

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.
