(vi) Statement of Work BACKGROUND The ship’s service and control air compressors on the T-AO 187 Class vessels need to be replaced. The Nash liquid ring rotary compressor units are inefficient to operate, costly to repair, and maintenance intensive. MSC requires a replacement for the current models with a more efficient, more reliable type of air compressor that has an economically feasible preventative maintenance program. The ship’s service air system requires clean, dry, oil-free air to serve various shops, whistles, atomizing, and tool hose services. The control air system serves various pneumatically operated valves, main engine clutch control, shaft brake, and various control valves. EQUIPMENT REQUIREMENTS MSC has performed an extensive evaluation of the various types of low pressure air compressors and air dryers and has determined that combined with avoiding extensive retrofitting of a new unit to the existing supply and service systems and overall performance requirements, the following requirements are necessary: 1. Screw type air compressor unit 2. 200 scfm or greater at 125 psig 3. Direct Drive 4. Footprint limitations a. Length not to exceed 85 inches b. Width not to exceed 75 inches c.

T-AO Solicitation N00033-04-Q-8000 Questions: · Is the requirement for (2) 100 SCFM compressors or (2) 200 SCFM compressors? Item 14a specs the Ship Service Air System at 200 SCFM. Requirement is for 2 compressors at 200 scfm each. Each needs to be capable of 100% of normal service. · The dryer package to be installed downstream of the compressors is only to be rated at 280 CFM. The air system description is for two compressors to be set up on a lead/lag system, which allows for both units to run at the same time for periods of time. Is the dryer to handle the flow of both compressors? No. As seen in the system drawings, the flow from the compressors goes to 2 air receivers in parallel. When a second compressor is running, its purpose is to bump up the receiver pressure to system operating pressure. The flow between the compressors and the receivers would then be 400 scfm. When the receivers are at operating pressure, the designed flow from receivers to the dryers is 200 scfm. Therefore, dryer should be sized for 200 scfm, 280 max. · If the compressors are 200 SCFM each, shouldn't the dryer be sized for the 400+ flow of both compressors? See previous response. · Does the ship system take air for another usage prior to the dryer? No, all air passes from the air receivers to the dryer before being distributed to the ship’s service air and control air systems. · Do the footprint dimensions, line 4, pertain to both compressors and the dryer combined, or do these dimensions apply to each compressor footprint? Requirement 8 asks for the dryer package as a separate skid mounted item. Line 4 refers to the footprint limits of each compressor only. · Does the weight on item 5 pertain to both the compressors and dryer combined or is that the weight of each compressor? Line 5 refers to the weight limit of each compressor only. · What is the air usage requirement downstream of the dryer? The dryer is asked to be capable of handling 280 SCFM, but this does not limit loses. Is this an inlet flow or a discharge flow requirement? 200 SCFM at 100 psig is the design operating inlet flow condition of the current dryer as originally designed. (280 SCFM max) Current desiccant dryer has 3-5 psig pressure loss. · Will membrane dehydrators be an acceptable alternative for a dual canister, desiccant dryer system? If air quality requirements in RFQ are met, equipment will be acceptable. · For the ABS/USCG requirements, what are they? Which ABS/USCG specs apply, and how do we get them? Please supply a contact we could discuss the requirements with. ABS Steel Vessel Rules 2004, Part 4, Vessel Systems and Machinery is available online at www.eagle.org . Some specific ABS rules that apply include, but are not limited to, section 4-6-7/5.5, regarding control air, and section 4-4-1 may be applicable regarding the fresh water heat exchanger. Requirements can be discussed further with ABS Americas, Alexandria office at 703-519-0801. USCG Regulations are covered in Title 46 of the Code of Federal Regulations, available online at www.access.gpo.gov . · Do the compressors being offered, need to be ABS/USCG approved, in order for the solicitation offer to be considered? Will compressors that are approved for U.S. Navy ship installation be acceptable alternatives for ABS approved? The compressor models offered do not have to be pre-approved by ABS/USCG. However, it must be capable of being approved by ABS upon submittal of unit specifications and a statement that the unit complies with an accepted standard (ANSI, ASME, etc.). Final testing will also be witnessed by an ABS surveyor at installation. Prior ABS approval greatly reduces the risk to the government. U.S. Navy installation improves the government’s confidence in the shipboard application, but is not an alternative to ABS approval. Note, ABS will review on behalf of the USCG. · What are the ship's pitch and roll requirements for this application? Design angles of inclination for shipboard machinery, per ABS Steel Vessel Rules 2004 and 46 CFR are: Athwartship: 15 deg Static, 22.5 deg Dynamic. Fore-and-Aft: 5 deg Static, 7.5 deg Dynamic. · For the central fresh water system on 14b, is 48 GPM flow available to each compressor package or is this the total flow available to be shared by both compressors? 48 GPM is the flow rate available to each compressor. · What constitutes a failure. If dew point is one of them then both dryers will need a dew point analyzer. We could do it with one analyzer but we would look at controlling both dryers with one PLC. That may not satisfy the "dual" nature of this request though. Dew point being out of spec would constitute a failure. One analyzer and one controller for two separate dryer elements would satisfy the redundancy requirement. · For the dryer, is there any preference for a heated vs. a non-heater dryer? Preference is for components with less complexity, electrical load, and maintenance burden that meet the requirements of the RFQ. · Are both stainless steel and painted carbon steel acceptable materials for the dryer? Yes, both are acceptable materials. · AIR DRYER PACKAGE: The "requirements" show dual prefilters and dual afterfilters with "automatic" switching upon element failure. The standard will be manual valve bypasses. Element failure means 0 psi drop to me. But what happens if pressure drop increases above 1-psi? Also, I noticed on the drawing that the wording says (air dryers, #1&2). I am assuming that this = one desiccant dryer package with 2 towers? The requirements state that the main dryer must have dual elements with automatic switching between the two. A dessicant dryer with two towers fulfills this requirement. The total number of prefilters and afterfilters is left to the bidder, so as not to limit the manufacturer's best engineering design and recommendation for the best operation of the system. If dual prefilters and after filters are used, manual switching between filters is sufficient. If a single prefilter and single after filter is used, manual bypass valves around the filters are sufficient. On the existing system diagram provided as GPI, air dryers, #1&2 refers to one desiccant dryer package with 2 towers. · OPERATING TEMP: Temp range is specified as 32F to 120F. The standard package will go to 115F. Will this be OK? The operating temperature requirement is 32F to 120F. The high end cannot be comprimised, as this temperature is often reached during operation. A lower temperature rating could result in lower capacity and increased maintenance. · ABS/USCG Approved: We have installed standard product via MSC in VA on-board vessels (as well as other marine applications). I am not sure how your guys "dealt" with this approval. Will standard product be OK or will it need to go through ABS/USCG approval?? The product and system as a whole must have the ability to be ABS/USCG approved. There are specific requirements for control air located in ABS Rules 2004, but the compressor unit itself does not have to be Type Approved. If similar products from a manufacturer were installed by MSC in the past, then the government has high confidence in ABS approval of this system with that manufacturer's products. NOTE: DATE & TIME OF SUBMISSION CHANGE Offers are due by 1200 hours local time, Friday, 19 March 2004. Proposals may be submitted via fax (202-685-5965) or email (Elyssa.Parana@navy.mil).
