a. The due date for the submission of quotations is unchanged at 15 August 2018 and no further extensions will be considered.

b. Incorporate the questions and answers as shown below.

SOW Item 22410 CPP Electric Pump Conversion:

Question: Paragraph 4.4.3 states to fabricate and connect the piping connections to the pump. During the ship check, the Chief Engineer stated that he wanted the CPP lines to the new pumps to be hard piped. The existing is hose. Will you please clarify how to proceed with the connections to the new pumps?

Answer: Clarified by adding paragraphs 4.4.3.1 through 4.4.3.4 to Item 22410; reference SOW changes below.

Question: Can you provide a drawing or piping diagram of the existing CPP piping to the CPP pumps?

Answer: Drawing SA9002 Rev G provided via email to all contractors on 2 August 2018 has a piping diagram of the existing system.

SOW Item 15050 Misc. Piping Repairs:

Question: Paragraph 4.2.2 states to perform a hydrostatic test of piping from the hull to the first inboard flange for 5 min @ 150 LBS. Is the SOW as per this paragraph still the same? During the ship check this work was discussed and was being considered to be rewritten due to the complexity of the testing as related to achieving SAT results.

Answer: Paragraph 4.2.2 in Item 15050 is modified to change the testing requirements; reference SOW changes below.

Question: Paragraph #4.5 states to weld a ½” schedule 80 seamless pipe and valve into the lower sea chests. What kind of valve should be installed?

Answer: Paragraph 4.5 in Item 15050 was modified to provide valve type; reference SOW changes below.

SOW Item 12430 Tail Shaft Survey and CPP Inspection:

Question: Are the GFE bearing housings not made and machined to the proper outside diameter size from the factory to fit the existing bores of the struts and stern tubes?

Answer: The bearings are remanufactured bearings that were spares for the Rainier and Fairweather. They were remanufactured by the OEM in accordance with the bearing drawing.

Question: Will the GFE bearings inside diameter dimensions be to the proper size to accommodate shaft journal diameters with the proper clearances? Or will the inside bores of the bearings have to be machined to proper size?

Answer: The inside bearing diameter will be correct.

Question: Are any of the current shaft bearings installed with Chockfast Orange for alignment purposes?

Answer: It is not known if Chockfast was used on the last installation.

SOW Item 15620 Port & Starboard Rudder:

Question: The replacements of the lower rudder bearing (reference 2.1 – Drawing: FA-S2201-1 Rudder and Rudder Stocks) says they are Bronze Rubber lined with a MIL-B-17901 (SHIPS) CL.2 in the description and that they are 16 7/8” long. Do you have any more information on these bearing (brand name, model number, part number, Outside diameter, Inside diameter, flange size, split shell housing)? Are these bearings a long lead time to get them?

Answer: Drawing FA-S2201_1 was provided via email on 2 August 2018 to all contractors with additional pages that were previously missing.

Question: Are any of the current shaft bearings installed with Chockfast Orange for alignment purposes?

Answer: It is not known if Chockfast was used on the last installation.

SOW Item 11100 Miscellaneous Structure Repairs:

Question: 4.1.7 Please provide additional definition to the requested repairs; location (frame #), dimensions, plate thickness etc.

Answer: The SOW was updated to change paragraph 4.1.7 of Item 11100; reference SOW changes below.

Question: 4.1.8.3 Please confirm that an "air box test" of plate seams will satisfy the intent of this requirement (this method is accepted by ABS).

Answer: Air box testing will be acceptable to NOAA if ABS accepts it.

Question: 4.1.10 Without specific definition of the individual applicable interferences, it is impossible to accurately estimate the cost of servicing this requirement. Please make removal and restoration of these interferences the subject of a negotiated change order.

Answer: Paragraph 4.1.8 of Item 11100 was updated to clarify insulation removal; reference SOW changes below.

Question: 4.1.11 Without specific definition of the location of repairs, it is impossible to accurately estimate the cost of performing coating repairs (If underwater hull coatings, repairs may require up to six coats of paint. If in way of an uncoated tank, repairs may only require 3 coats of paint. Painting within a confined space is significantly more difficult than an open area). Please make application of coatings the subject of a negotiated change order.

Answer: Paragraphs 4.1.10 thru 4.1.12 of Item 11100 were updated to include clarification on paint, interferences and insulation; reference SOW changes below.

SOW Item 14430 Machinery Control Updates:

Question: Item 14430: It's understood that specified parts and/or vendors are no longer in existence, are equivalent items acceptable? (4.1-4.1.2)

Answer: The material procurement was removed from this item in paragraph 4.1; reference SOW changes below. Both vendors listed should still be open for business.

SOW Item 15050 Misc Pipe Repairs:

Question: 150lb testing will be difficult to accomplish. Will interior pipe cleaning and visual inspection suffice? ASTM B-467 is a copper-Nickel Procedure; can the proper ASTM procedure be provided?

Answer: Paragraph 4.2.2 of Item 15050 was updated to include new testing requirements; reference SOW changes below.

The ASTM in the spec was updated to ASTM A53.

SOW Item 15620 Rudder Inspection:

Answer: Reference 2.3 was provided as part of the first delivery of references 19 July 2018. Sent via AMRDEC File. Pipe routing is intentionally left open to allow for field routing.

SOW Item 25290 Oily Water Storage Tank Modification:

Question: SOW is vague, how to quote on interferences? Model of TLI required for this system? The chief engineer requested this same model as existing TLIs on other systems but this is not specified in this work item.

Answer: Design drawings FA-528-001 and FA-593-001 have been updated to include the TLI. They were provided to all contractors via email 2 August 2018.

SOW Item 15330 Potable Water Tank Recoat:

Question: Item 15330 Please provide square footage, if more than 2 tanks how many in total?

Answer: The tank drawing has been provided as part of the first submission of references 19 July 2018, via AMRDEC File, and sqft may be calculated from it. The drawing # is FA-S1101-2. Both potable water tanks shall be fully blasted and recoated.

SOW Item 16310 under Water Hull Preservation:
