Request for Information Notice Q A

1. Existing High-PAC Booster: The specification states that the high-pressure booster compressor shall match the make and model of the command’s existing High-PAC fleet. Can you provide the manufacturer and model number of the existing High-PAC booster equipment?

Answer: The Make is American Compressors Model# 55H75 Model Name: Universal High PAC

2. Bottle Bank Configuration: The specification calls for approximately 36,000 SCF of highpressure storage. Does PSNS have a preferred bottle size, quantity, rack configuration, or number of independent banks, or would you prefer that we propose the optimal configuration?
Answer: Like the container the solution proposed needs to be able to be safely moved with cranes and forklifts. The goal with the external bank configuration was to alleviate the design constraints of the main systems footprint/volume (20’ ISO Containier) by making the storage system more open to a COTS bottle bank solutions that could meet our supply needs.

3. 100 SCFM Requirement: Can you confirm whether the 100 SCFM continuous delivery requirement at 350 psig is intended to be supplied from the high-pressure storage banks during the 40-minute draw cycles, with the nitrogen generation/compression system replenishing the banks between/during draws? Or is the generation/compression equipment itself expected to continuously produce 100 SCFM? Answer: The peak demand on the supply is 100 SCFM in 40min cycles. The bank capacity will provide supply for a full shift. 350 PSI is the solely final supply pressure and does not control SCF capacity.

4. Grade D Feed Air: For the shipyard-provided Grade D breathing-air connection at 90– 125 psig, can you provide the available flow capacity (SCFM) at the intended connection point?
Answer: The commands Grade D supply air capacity can meet the systems demand.

5. 20-ft Container Configuration: The specification indicates that the complete system should preferably be contained within a single 20-ft ISO 668 Type 1C container. Is the 20ft configuration expected to be a firm requirement for the eventual solicitation, or would PSNS consider an alternate configuration if necessary to optimize performance, maintenance access, or safety?
Answer: The intent with the 20ft container is the need for a common and easily transported system within our command. The main concerns are a mature storage/transportation system that is well suited for safe system storage and operation in an outdoor marine environment while being transportable via crane, forklifts, and
