Agenda









Issues and Concerns

13




Shift from MSMO Cost plus Incentive Fee contract vehicles to Firm Fixed

Price contracts in all AORs.

• Package lock date moves from A-99/A-75 to A-170.

Single deferral letter required at A-220 ISO Firm Fixed Price availabilities

and earlier package lock.

• Previous requirement was one deferral letter at A-240, another at A-120, in

support of A-99/A-75 package lock.

• New requirement is only one letter at A-220. Response from Ship Design

Manager should be back to MT prior to A-170 package lock.

• This cuts the admin burden of deferral letters in half.

• As before, Type Commander MAY write additional deferral requests any time,

as needed.

14




Branding Review (“AR” Category of Work) from A-150 to A-250

• First SURFMEPP review of CSMP will still be at A-440, ISO A-410 Mid-Cycle

Review.

• Second SURFMEPP review of CSMP will be at A-250. This will give MT time to

put “AR” branded items into work package OR into A-220 Deferral Request.

• No new jobs are pushed to the CSMP – this is a review of existing CSMP jobs

for SSEOC impact items. We will notify MT before changing Category of Work.

CMP Situational Periodicity Code change from A-150 to A-360

• All CMP tasks with SPC of A-150 will now be due at A-360. Goal is earlier

completion of assessments and earlier work identification ISO earlier package

lock.

• No additional assessments, requirements or workload. Just changing WHEN.

15




Non-Mandatory TSRA tasks Closure Method = MA COMPLETE

• 811 (A1), 816 (A6), 832 (AR), 833 (AH), and now 849 (B9) Type Sequence

Number are all changed to “MA COMPLETE” via VSB script.

• Port Engineer should not have to Customer Close these jobs when MA

executes and closes these jobs in TAAS, AIM or NMD.

Removal of CDNS – Per PE requests, SEA05 has also concurred

• First step: All CDNS notifications will be EXEMPT (no auto-generated emails). Deferrals of

MTRs will all be via letter process (AWPM/TDCA can assist).

• You will get the pop-up window as a notification but it won’t stop you from screening

• 2nd step: remove from VSB altogether

Class Standard Work Templates with

“Front Load”

Method:

Obtain relevant historic maintenance data from NMD. We

started with the SWLINS with the most growth in CNO avails.

Review current CSWT to identify functional area coverage

Look for repeated /recurring maintenance actions

Compare maintenance actions to the current CSWT:

• If maintenance actions are covered adequately by CSWT, no

modification needed

• If maintenance actions are not covered, generate recommendation

based on average/median of data

• If an existing reservation is not required, it will be removed

23



Top Growth for all Surface

Ships

24



Example: CG Gas Turbine

Exhaust Repair

Developed Two CSWTs - One for 1A and 1B and One for 2A and 2B - to

include the following reservations:

• 10 linear feet of Vee-out and weld repair

• 10 manhole cover studs replaced

• 10 manhole cover bolting ring holes repaired

• 450 ft2 of interior insulation replacement

• 100 ft2 of perforated sheathing panel replacement

• The following CSWTs have been modified to include the reservations:

• CSWT 259-008 1A and 1B Gas Turbine Exhaust; repair

• CSWT 259-002 2A and 2B Gas Turbine Exhaust; repair

MSA Definition

Created and codified via the NMPT in NDE

MSA ALTS identified in NDE by selection of the “Mandatory

Safety Alteration” field

Safety risk assessment provided by ALT sponsor

Currently SURFMEPP uses a list of MSAs provided by

SEA21 (vetted by SEA05)

27

Official Definition of “MSA” Approved - NDE Being Populated



MSA ID, Tracking and Deferral

SURFMEPP reviews LOA and IDs MSA

Pushes MSA JSN to MT and brands “AS”

• “AS” in JFMM as “Mandatory Safety Maintenance”

- Volume II, Part I, Chapter 3

- Being added to Appendix “AN” at next JFMM BoD

• Set Due Date to end of CNO avail and notifies stakeholders

Reviewed at E2E meetings (LCPC, A-410, IPTD, and C+70)

Tracked in A-360, Deferral and Closeout letters

Stakeholders notified if LOA change removes MSA

Deferral through LOA change process vice JFMM

28

Deferral from FRP to FRP may be an SSEOC reportable requirement

CNO Availability Services and

Routines

In an effort to standardize Services and Routines and the associated

processes need to ensure jobs are on the CSMP, SURFMEPP

conducted an analysis to identify tasks needed to support the

planning and execution of CNO availabilities

Tasks were divided into two categories, Core and Optional by AOR

Task review is complete in Norfolk

Task review is ongoing in San Diego

30

CNO Services & Routines Under Review For Standardization By AOR



Core Services and Routines

Core Services and Routines are tasks deemed required to support

the planning and execution of the CNO availability

The AOR specific Core Services and Routines were developed by

SURFMEPP and concurred upon by the TYCOM and RMC

Core Services and Routines will be discussed at LCPC

Core Services and Routines will be pushed with the BAWP but will

not be branded mandatory

31

Core Services & Routines are Pushed with the BAWP



Optional Services and

Routines

Optional Services and Routines are unique package relevant tasks

deemed needed to support the planning and execution of the CNO

availability

The AOR specific Optional Services and Routines were developed

by SURFMEPP and concurred upon by the TYCOM and RMC

Optional Services and Routines will be discussed at LCPC and the

A-410 meeting

Optional Services and Routines will be pushed to the CSMP when

requested by the Maintenance Team

32

Optional Services & Routines Pushed at Maintenance Team Request

Mandatory Safety Alterations &SURFMEPP role in modernization


Issues and Concerns

33



Issues and Concerns

CSMP Management

• Tasks must be completely closed out in VSB – Last Accomplished Date does not update until the

JCN is closed out. Job will continue to appear on “overdue CMP task” list until closed.

• Jobs that are NOT complete must stay on the CSMP – If the job is still valid, leave it open so we

can put on Ship Sheets and ensure you have the budget for it in the next cycle.

• All DFS need a JCN – A DFS can’t be screened and brokered…only a JCN can be screened and

brokered. Without a JCN there is no mechanism to actually get it fixed.

CMP Task Ownership

• If it is in the CSMP with an “A” Category of Work it is PE responsibility to Screen and Broker (or

get deferred by SDM).

• When it is assigned to the RMC it is their responsibility to get it accomplished.

• “Upon completion of a mandatory assessment, the assessment team is responsible for creating

CSMP-ready repair AWRs”

• BAWP report is distributed every 30 month. Full listing of all “A” Category of Work items in the

CSMP with a due date in the current cycle, WITH current status (Avail plus authorized, assigned,

rejected, on hold, etc)

34



Issues and Concerns

CMP Task Feedback / TFBR

• If a CMP task is not right (not executable as written, wrong periodicity,

mismatch with tech manual, etc.), don’t just “live with it” - give us that

feedback so we can fix it.

• If no task exists for a piece of gear, but it should – we can help with that too.

We can work with ISEA / TWH.

• You can write your own TFBR in PMSMIS, or you can talk to / email / call your

local SURFMEPP detachment. We can either show you how to do a TFBR or we

can do it on your behalf.

Deferral Process

• Not being fully utilized. We still see items not accomplished but never

adjudicated on almost every closeout letter. If you know it can’t / won’t be

done, request deferral. Call your AWPM / TDCA.

• Deferral letters can be submitted at any time. RMC Chief Engineer can also

adjudicate tasks during execution, per JFMM.

The Good News about…


ICMP Task Number: Q-58420-A01 MRID: 106245 Periodicity: 72M

Short Description: Overhaul Stern Gate Mechanical System

Cost Estimate: Man-days: 54 Material: $210,910 Associated CSWT: 584-024

Class Applicability: LSD 41/49 First Hull: USS ASHLAND (LSD 48)

CMP

Task at a

Glance:

Background: Stern gate hydraulics and operating equipment are high usage items that are

operated in a harsh exposed environment which can lead to increased corrosion.

System downtime can impact amphibious operations and the ship’s ability to

meet mission tasking.

Strategy: Preserve Stern Gate Foundation and Cylinder to include rebuilding of the Port

and Starboard Hydraulic Cylinders (and associated components).

Benefit: Time directing the maintenance in the CMP will improve the overall maintenance

strategy for the stern gate equipment, provide a budget for better and lower cost of

continuous maintenance, while minimizing the excessive costs of growth and new

work; all of which will increase reliability and support the primary mission of the

ship.

Questions concerning this CMP Task should be addressed to: [email protected]

corrosion of sea chest valves and piping components. Waster sleeve removal facilitates

proper inspection of sea chests. Standard waster sleeve configurations require the sea

valve to be removed, most times damaging the waster sleeve in the process. Sea valve

inspections are preformed to accurately assess the extent of damage requiring repair.

Repairs vary in cost, smaller valves often exceeds 50% of the cost of a new valve.

Strategy: Replace sea valves 2 ½ inches and below, overhaul sea valves greater than 2 ½ inches

within every normal docking interval. Replace waster sleeves in conjunction with the sea

valve task.

Benefit: Additional costs to remove sea valves for repair is eliminated, the cost of valve removal is

rolled into the cost of the waster sleeve repair. Catastrophic failure to sea valves that are

exposed to harsh environments are reduced. Decrease need for costly diving services that

pose logistical challenges affecting ships operational requirements.
