3. BACKGROUND:

a. Reference (a) reported defects in an anchor, anchor chains, and chain appendages found during the visual inspection.

b. Therefore, ESR MCM7-395 was issued requesting SRF-JRMC Det. Sasebo Design Branch Code

S245 to evaluate the reported defects and provide appropriate direction.

ELM255094A CUI 1 of3 k.

ICN 3807G58201_A07

CUI

4. GENERAL NOTES:

a. The purpose of this ELM is to provide recommended actions for the defects found in the anchor, the anchor chain, and chain appendages.

b. SRF-JRMC Det. Sasebo LTA Code S200 approves the recommendations in required actions below.

c. All general notes in references (d) thru (f), (i), and (j) apply.

5. REQUIRED ACTIONS:

Recommended actions for each component are as follows:

[Anchor Assembly]

a. For linear indications in the anchor assembly [reference (a), #1, 11, 12 and 13 of VISUAL

INSPECTION ANCHOR],

i) Perform PT or 5X VT inspection to identify all indications in the immediate area

(Approximately 1 inch in circumference) instead of MT stated in paragraph 581 ofreference (c).

ii) Grind the linear indications in stages and stop when sound metal is reached.

• The maximum grinding depth is 1/4-inch. If the linear indication remains after removing 1/4-inch, submit a CFR to receive further direction from the Project Team.

• Grinding shall be accomplished so that there are no unnatural irregularities on the metal surface.

iii) Perform either PT or 5X VT inspection, and ifno linear indications are identified, the anchor can be reused.

b. A broken split key, PC NO 9 ofreference (d), [reference (a), #14 of VISUAL INSPECTION ANCHOR] shall be fabricated and replaced in accordance with references (d) and (e). The use of K-Monel is acceptable in place of Hadfield Steel as per General Note 11 in reference (e).

c. Dents and pits reported in reference (a) [#2 thru IO of VISUAL INSPECTION ANCHOR] are considered to have occurred during the initial manufacturing of the casting. None of them fall within the scope of the repair requirement specified in paragraph 581 c of reference ( c ). The above mentioned defects are considered acceptable as-is. Therefore, no further action is required.

[Chain Stopper Assemblies]

a. A broken chain [PC NO 13 ofreference (f)] shall be replaced in accordance with references (e) and

(f). The use of K-Monel or CRES 316 is acceptable in place of Hadfield Steel.

b. Six (6) missing locking plates and six (6) cotter pins [PC NOs 19 and 20 ofreference (f)] in the chain stopper assemblies shall be fabricated and installed in accordance with references (e) and (f).

The use ofK-Monel or CRES 316 is acceptable in place of Hadfield Steel.

c. For an eyebolt with linear indications [PC NO 18 ofreference (f)], procure a replacement [Item 7d in this ELM] and replace the existing with a new one in accordance with references (e) and (f).

d. No repair action is required for cracks in the bail pin end [PC NO 11 ofreference (f)] of the pelican hook in one of three (3) chain stopper assemblies. It will be documented in a minor permanent DFS, MCM-7-1000-2025. The rationale is as follows: Similar issues previously

ELM255094A CUI 2 of3

ICN 3807G58201~A07

occurred on MCM-14 & MCM-9, and were authorized to leave the as-found condition permanently as documented via references (g) and (h), respectively.

[ Anchor Chain]

a. For the two (2) anchor chains with linear indications (reference (a), #23 in No. 5 shot and #204 in

No. 6 shot), replace with a detachable link [Item 7e in this ELM] in accordance with paragraph 581-5.4.3 ofreference (b).

b. For the anchor chain with ark strike (reference (a), #89 in No. I shot), remove ark strike and perform visual inspection. If there is any defect, submit a CFR.

c. Structural integrity is not affected by the pinhole in the welding (reference (a), #86 in No. I shot), the crack in the weld between the link and the bridge (reference (a), #183, 184, 188 in No.I shot, #55, 78, 79, 153, 169 in No.2 shot), and the larger than normal forging cleft (reference (a), #160, 166 in No.6 shot, #51 in No. IO shot). Therefore, no further action is required.

6. TEST NOTES:

@ a. For the chain stopper assembly with the replaced eye bolt, a proof test and inspections shall be performed in accordance with general note 6 in reference (f) as follows:

I) Perform proof test incorporating the required number and type of detachable links and held 15 second without developing any rupture or surface crack.

• The proof load shall be in accordance with table No. I of reference (f).

2) After completion of the proof test, perform visual testing (VT) for dimensional conformance.

3) After completion of VT, perform penetrant testing (PT) in accordance with T9074-AS-GIB

O 10/271 . Acceptance standard in accordance with MIL-STD-2035A, class 3 shall apply.

• Since the chain stopper assembly is non-magnetic, it is acceptable to perform PT instead of magnetic particle testing (MT).
