PROBLEM STATEMENT:

1. SRF-JRMC Detachment Sasebo has been requested an installation of mechanical joint (MAF) on the fire main OVBD discharge piping (2-1/2" NPS, P-ID of Ref. (A)]. See P/E comment below.

2. SRF-JRMC Detachment Sasebo Design recommends installing a flange. See Attachment-(1).

3. TYCOM Port Engineer for LHA7 reports degradation of sea water piping throughout the ship due to the incorrect type (Grade II vs Grade I of appropriate MILSPEC). Piping for this job currently has two significant leaks which are impacting Fire Pump 15 & 16 (Both are CASREP).

4. Piping to be replaced is located less than 5 feet below No. 10 cargo AMMO MAG (5-97-0-M) which due to scheduling conflicts is unable to have ammo offloaded. This prohibits ability to perform welding onboard.

5. Installation of flange will enable replacement of degraded piping sections without the need to offload ammo and allow ship to meet schedule/mission requirements as well as facilitate easier replacement in future.
