Questions

WJs are still listed and approved under SFLC Std Spec 6310.

WJs are acceptable only when remaining surface profiles still meet standards and requirements.

Otherwise, any surface prep areas failed to meet standards and requirements must be corrected/implemented by SP-10 or SP-10 (WAB) or equivalent.

2. For estimating purposes, please provide surface areas for the regions shown in Table 1 as well as the "adjacent structural members" referenced in paragraph 3.4 & 4.1. Total Overall Preservations ~ 25,500 sqft Freeboard ~ 18,000 sqft Transom ~1,800 sqft Other miscellaneous surfaces 1,800 sqft Visual safety and identification markings ~ 300 sqft Touch Up ~ 1,800 sqft Please see "Tap WI4 Freeboard" for Tables and Details

2. For estimating purposes, please provide surface areas for each location listed in Table 1, Table 2, and Table 3 as well as all the structures noted in paragraph 4.1 and 4.2. Total Overall Preservations ~ 14,762 sqft Partial : All Top Coat Layer ~ 11,012+ sqft, and Primer & Mid-Coat ~ < 30% Other miscellaneous surfaces 1,500 sqft Visual safety and identification markings ~ 150 sqft Touch Up ~ 2,100 sqft Please see "Tap WI5 Superstructure" for Tables and Details 6 U/W Body Hull, Preserve (Full) 1. Paragraph 3.1.7 notes that "The Contractor may have the option of using either “Wet Abrasive Blasting” or “Dry Abrasive Blasting” to achieve the required surface preparation…" The note in this paragraph states that "Water jetting without abrasive addition does not provide any additional anchor profile to the surface, beyond what was present after the previous surface preparation.". Contractor requests that the USCG consider revising the work specification to allow for Water jetting without abrasive addition. With new construction, abrasive blast media is needed to achieve the required anchor profile, but with repair the anchor profile already exists, and Water jetting without abrasive addition is generally an acceptable surface preparation method; the Navy and other government agencies allow for this surface preparation method. Water jetting without abrasive addition will provide the government with a better value.

WABs and DABs are requested and preferred respectively.

2. Sea trials should be able to be accomplished during transit from cutters homepier to to DD facility. Once formal awards are made, and the gov. is provided with the production schedule and required pre-work inspections, planning and scheduling of trials can be discussed and formalized.

17 Propulsion Shaft Coverings (MIL-STD-2199B), Inspect and Repair 1. A level of effort cannot be determined based on the information provided for paragraph 3.31 & 3.32. Paragraph 3.4 is only required if repairs are required. Please confirm that paragraphs 3.3.1, 3.3.2, and 3.4 are all subject to and pending the contract modification noted in paragraph 3.3. 1. For bidding purposes the contractor must estimate up to 10 sq/ft of repairs per shaft.

18 Propulsion Shaft Seals (Mechanical), Overhaul 1. Please confirm that the operational tests noted in paragraph 3.6.2 & 3.6.3 will be replicated prior to the start of the work associated with this Contract. It is important that the Government and the Contractor have a deep understanding of the conditions found prior to executing the overhauls/repairs associated with this work item. 1. Sea trials should be able to be accomplished during transit from cutters homepier to to DD facility. Once formal awards are made, and the gov. is provided with the production schedule and required pre-work inspections, planning and scheduling of trials can be discussed and formalized.

19 Controllable Pitch Propeller Hub Assembly, General Maintenance 1. Please confirm that the operational tests noted in paragraph 3.12 will be replicated prior to the start of the work associated with this Contract. It is important that the Government and the Contractor have a deep understanding of the conditions found prior to executing the overhauls/repairs associated with this work item. 1. Sea trials should be able to be accomplished during transit from cutters homepier to to DD facility. Once formal awards are made, and the gov. is provided with the production schedule and required pre-work inspections, planning and scheduling of trials can be discussed and formalized.

20 Controllable Pitch Propeller System, Perform General Maintenance 1. No flushing procedure or detailed procedure for refilling the oil into the system are provided with this work item. Please confirm that the flush per the requirements of Work Item 19, paragraph 3.7, is all that is required relative to the CPP System. 1. Flush and fill outlinbed in WI 19 3.7 meets requirements for this WI. 3.7 Fill and flush the propeller hub. The Contractor must fill and flush the propeller hub in accordance with Section 7 (Maintenance Instructions), Paragraph 2.7.1 of CG TP 7153A.

3.7.1 Process any new oil added to the hub or hydraulic system through a non-bypass filter assembly prior to its introduction into the CPP hydraulic system. Filter assembly must utilize new clean disposable filter elements with a minimum Beta 10 = 75 ratio rating. Do not exceed filter assembly and/or element flow ratings or pressure ratings (both maximum collapse as well as delta across) during filling.

3.7.2 The Contractor must refill the CPP System using new Contractor supplied oil in accordance with Section 7 (Maintenance Instructions), Paragraph 5 of CG Tech Pub 7153A. Ensure that all air is vented from the system, and that the hub, shaft, hydraulic power unit and CPP gravity head tank are all filled to their proper levels. See Table 1 for approximate oil capacities. The minimum level of oil cleanliness must be 16/13 per ISO 4406. Submit a CFR documenting oil filling records.

It is applied in Pre-award Drydocking Calculations to check and evaluate the Contractors' abilities.

2. Please confirm whether it is the Government's or Contractor's responsibility to adjust loading conditions, relative to the "Estimated Drafts/Loading Conditions" to provide an acceptable docking condition for the Contractor's Drydock. Cutters ( Government's) will only adjust required Liquid Loads/Loading Conditions/Arrival Drafts to meet Safe Conditions for Drydocking. (e.g ~ 0 List, Min Trim, Adequate Stabilities) In the other hands, the Contractors must also provide Docking Calculations at Arrival Drafts/Loading Conditions, and accomplish Safe Docking at Arrival Conditions accordingly.
