(I) GIN6 Level 2 Structural Inspection Report for Multiple Compartments in LSD-47, dated 12 Sep 2024

3. BACKGROUND:

a. Reference (a) thru (s) required a Level 2 structural inspection as the follow-on inspection to Level

I surveys performed on 21 Mar 2023 thru 7 Jul 2023.

b. Level 2 structural inspections were performed in accordance with references (t) thru (w) on 1 Jul 2023 thru 18 Aug 2023. With concurrence by SRF Sasebo Code S200 (acting), a decommissioning requirement in paragraph 6-9 of reference (u) was applied to the Level 2 inspection. This requirement allowed ships within 5 years of decommissioning to indefinitely defer required repairs not affecting the safe operation of the ship. They are listed in the Level 2 structural inspection report, enclosure (I). However, prior to releasing the report, the ship' s decommissioning date was extended to 2031 , which is outside the 5-year window. All listed deficiencies were re-evaluated to be repaired as the normal requirement.

c. As a result of the inspection, (76) structural defects/findings were identified and evaluated as follows:

• R5/S5 - 6 Items

• R4/S5 - 3 Items

• R3/S5 - 42 Items

• R2/S5 - 6 Items

• Others - 19 Items

4. GENERAL NOTES:

a. The purpose of this ELM is to release a Level 2 Structural Inspection Report, enclosure (I).

b. The repair of non-conformances listed in Level 2 inspection report is planned in accordance with Structural Maintenance Decision Risk Matrix (SDRM) in reference (v). The non-conformances not repaired per SDRM will be documented in a Departure from Specification (DFS).

5. REQUIRED ACTIONS:

a. Perform all recommended repair actions identified in the Level 2 Structural Inspection Report, enclosure (1 ).

6. TEST NOTES:

a. Verify that all tightness requirements to the compartment' s boundaries are restored with the completion test. Testing shall be in accordance with section 192 in reference (x). The alternative methods specified in paragraph 192f are allowed.

LEVEL 2 STRUCTURAL INSPECTION REPORT

ASSESSMENT AND CORRECTIVE ACTION

I. This Level 2 structural inspection was performed as the follow-on inspection of Level I survey, reference (I) thru ( 19).

With a concurrence by SRF Sasebo Code S200 (acting), a decommissioning requirement in paragraph 6-9 of reference

(20) applied to the Level 2 inspection. Therefore, deficiencies not affecting to safely operate the ship are not required to repair. They are listed in herein. However, prior to releasing this Level 2 inspection report, the ship's decommissioning schedule was changed to more than 5 years later. It took the applied recommissioning requirement out. All listed deficiencies were re-evaluated to be repaired as the normal requirement.

a. On 21 Mar 2023 thru 7 Jul 2023, a Level I survey was performed by a qualified surveyor in SRF Sasebo QA Code S 137. On I Jul 2023 thru 18 Aug 2023, the Level 2 inspection was performed in accordance with references (20) thru (23).

3. BACKGROUND:

a. Reference (a) is applicable to all homeport ships at Yokosuka.

b. Historically SRF Sasebo has referred the web and flange thicknesses shown as the fractional value listed in Tables 1-1 thru 1-10 in reference (b ). The fabricated built-up Tee has been made of the equivalent grade steel to the original.

c. ESR MISC-288 requested a Standard ELM for built-up Tees, similar to REF (a), applicable to Sasebo homeported ships.

d. The installation of a built-up Tee as the substitute for a Tee shape is supported by paragraph I 00-

2.8.6 in reference (c).

4. GENERAL NOTES:

a. The purpose of this ELM is to provide guidance for the fabrication of built-up Tees.

b. SRF Sasebo Engineering Branch Code S245 concurs with the use of a built-up Tee as the substitute for the original Tee shape. The built-up Tee must have adequate proportions to ensure its capacity to achieve the necessary strength, while being substantially equal in weight to the original. The following rational was used to figure out all the dimensions for an acceptable built-up Tee.

( 1 ). Per paragraph 7 .2 in reference ( d), the dimensions and properties of US standardized structural members are set by industry standards such as reference (e). In order to achieve the strength levels discussed in section 11 ofreference (d), it is essential that structural sections be of adequate proportions to ensure their capabilities to achieve the necessary strength levels. To prevent premature buckling, tripping, or collapse, stiffener webs should not be extremely slim, and stiffener flanges should not be exceptionally wide. In general , stiffeners complying with the requirements of reference ( e ), and their international equivalents, are of adequate proportions. Stiffeners used as deck beams, bulkhead stiffeners, web frames or shell stringers should be proportioned to prevent lateral buckling or laying over of the flange.

(2). All cross-sectional dimensions of the built-up Tees shown in Tables 1, 2 and 3 of this ELM are rounded from the original ( design) dimensions to the nearest 1/16th of an inch. When the section modulus for the web and flange, or the shear area are calculated and found to be less than 95 percent of the original, the thickness is rounded up to the nearest I/16th of an inch.

(3). All fillet weld sizes in Tables 1 thru 3 in this ELM were calculated for the specific combinations of the web/flange material and filler material in accordance with Chapter 5 in reference (f) with 100 percent joint efficiency. The calculated combinations are shown in the following table:

ELM 235124

Symbol in Tables 1 thru 3 Web and Flange Materia1•1 Filler Material Type (listed in Table 5-3 ofreference (f))

OS - 70XX OS MIL-70XX*2 or MIL-80XX-C3 HS - 70XX HS MIL-7oxx·2

HS - 80XX HS MIL-80XX-C3

* 1: Both of web and flange materials should be same grade.

*2: MIL-70S-1 type in Table 5-3 in reference (f) is considered as the equivalent to figure out the fillet weld size, and is allowed to use by this ELM.

CUI/ /SP-CTI/FEDCON

I 3/ 2 of 10 /J!,

c. When only the web or the flange portion of the Tee shape is to be replaced, the dimensions should follow the guidance in this ELM.

d. Fabrication, welding, and inspection shall be in accordance with NA VSEA S9AA0-AB-GOS- 0l 0/GSO, NAVSEA S9086 CH-STM-010/CH-074 and MIL-STD-1689A. The weld joint design shall conform to MJL-STD-22D.

e. The fabrication guidance in this ELM may be utilized without concurrence by SRF Sasebo Engineering Branch Code S245, as long as the given situation meets the guidance laid out in this

ELM.

f. When SRF or any contractor hired by SRF cannot receive the Tee shape material within the time constraints of a ship maintenance availability, a built-up Tee shall be fabricated per this ELM and applied to the structural repair as substitute.

g. Built-up Tee shall be the substitute for Tee shapes made of ordinary strength steel (OS) or higher strength steel (HS) conforming to reference (g) or any ABS Grades.

5. REQUIRED ACTIONS:

a. Fabricate the built-up Tee using Figure I of this ELM. The flat bar or plate material must be equivalent in grade to the original shape' s material being replaced. The dimensions of the built-up Tee and corresponding fillet weld size are given in Tables 1 thru 3.

(I). If plate material is used to fabricate the built-up Tee, the axis direction of the web or flange member should be cut out along with a rolled direction of the plate material.

b. Consult SRF Sasebo Engineering Branch Code S245 when fabricating any built-up Tee with different material thicknesses other than those listed in this ELM or when fabricating any non-listed Tee shapes.

6. TEST NOTES:

a. VT inspection shall be performed for any welding in accordance with reference (h).
