TITLE:

QUESTION: Para 3.4.2 is titled “Pit measurement” and directs KTR to take 150 UT measurements. Will USG clarify?

A/C Conditioning Condenser Renew

QUESTION: OEM Technical is requesting the last eddy current test report for 3A AC condenser. This report will provide details, including specifying which tubes require replacement, along with information on corrosion levels, coating thickness, etc.

RESPONSE: The identified issues were not seen on the eddy current report, so that will not tell them much. Upon visual inspection when the condensers were last opened, we saw that the ends of the inlet tubes in the tube sheet were eroding away due to high water flow into the condenser. Because these defects were at the tube/tube sheet interface, they did not appear during eddy current testing. The number of tubes to be renewed in the base SOW is all tubes on the lower half of the condenser, which is the inlet side.

Task 10

Anchor Windlass Level 2 Inspect and Repair

QUESTION: Task 10 Preserve leads to STD Spec 5000 3.2.4 Abrasive-blast to SSPC-SP10/NACE No. 2, using grit conforming to MIL-A- 22262 (1.5 to 2.5 mil anchor profile).

3.2.4.3.1 When Preserve is specified in a task description, prepare 100% of all surfaces designed to be coated.

The Level 2 disassembly is not adequate for 100% Blasting, inaccessible areas and sensitive surfaces, seals and bearings would be at risk, in addition, the likely hood of creating potential damage to the surrounding Forecastle areas is likely.

Contractor recommends this requirement to be partially preserve Std Spec 5000 as stated below:

3.2.4.3.2 When Partially-Preserve is specified in a task description, do the following:

Remove coatings only in areas in which mechanical damage extends into the substrate, or where there is evidence of corrosion (see 3.2.4.3 (Surface preparation)).

Roughen/abrade all surfaces of the entire assembly where existing top-coating is intact with 100-grit paper, to provide a suitable surface profile. Feather edges of top coating into adjacent bare areas, to create a smooth transition. Complete Overcoat.

RESPONSE: I concur with FEDMAR’s recommendation. We can change it to a partial preservation as called out in that paragraph of SFLC Std Spec 5000 to include fully abrading intact coatings and applying a full topcoat.
