| 032 | 6/19/20 | RFP, Section L | Page 154, 2.4.2.1.4 | Will the government consider removing the verification cross reference matrix/table from the page count. This matrix/table will take up several pages but does not add additional information about the offer to the technical volume. | Solicitation N0002420R4112 Section L paragraphs 2.2.4 and 2.4.2.1.4 have been modified to clarify the requirement. | |
| 033 | 6/19/20 | RFP, Section L | Page 154, 2.4.2.1.4 | Will the Government be identifying what it considers "performance requirements" for the development of a verification cross reference matrix/table or is it the intention that the offerer will extract what they deem "performance requirements" from the Section J Attachments. | Solicitation N0002420R4112 Section J Attachments B through H include Navy approved Technical Performance Specifications which will be used to evaluate proposed design and eventually verify performance of designed and built hardware. Solicitation N0002420R4112 Section L paragraph 2.4.2.1.4 has been modified to clarify the requirement. | |
| 034 | 6/19/20 | RFP, Section C | Page 14, 0.3.2.1 | An FRD document is referenced as Government Furnished but no specific FRD was included in the data package. While several attachments are tagged with FRD numbers, was it the intent of the Government to provide a separate FRD or have the offerer create their own? Will the Government provide an electronics database of requirements? | No. The Government furnished Energy Magazine Functional Requirements Document (FRD) is a Microsoft Excel depiction of the language fully contained within Solicitation N0002420R4112 Section J Attachments B through H and will be provided as Government Furnished Information post contract award to avoid any ambiguity on the requirements. All FRD references made in the solicitation N0002420R4112 Section J Attachments B through H documents are word for word identical to what is written in the RFP. | |
| 035 | 6/19/20 | RFP, Section L | Page 155, 2.4.2.1.6.1 | "The Government will not consider any technical solutions for which the following subsystems are TRL 5 or lower: Power Electronics at the component level...". To help "normalize" our TRL assessment, does the Government consider >6kV SiC TRL 6 or higher? If not, how does the Government reconcile the stated goal (Section 0.2, pg 12) to incorporate "wide band-gap power electronics devices (such as Silicon-Carbide (SiC), greater than 6KV rating) into the power conversion equipment" against the TRL requirement in 2.4.2.1.6.1? | Solicitation N0002420R4112 Section C paragraph 0.1 contains program goals and not explicit requirements. The assessment of technology maturity is the responsibility of the Contractor to correctly identify and provide an accurate TRL for each major energy magazine subsystem. | |
| 036 | 6/19/20 | RFP, Section C | Page 26, 1.1.4; Page 37, 1.3.1.1 | The Government is requesting a number of battery assets necessary to complete S9310-AQ-SAF-010 and SG270-BV-SAF-010 testing. Can this list of required test assets be reduced depending on the level of qualification previously achieved, under this same qualification criteria? | No. Any presumed exemption from providing these test assets may assume a level of qualification that may not be verifiable as part of the offer. | |
| 037 | 6/19/20 | RFP, Section C | Page 28, 1.2.1 | "If insulating material is being considered to reduce the creepage and clearance distance...material...process...shall be submitted to the Government as a Request for Variance for approval by the Government". All insulating material by definition is to reduce creepage and clearance, even on commercial wire. Can the Government better define where approval for insulating material is required? | Solicitation N0002420R4112 Section C paragraph 1.2.1 requirement is applicable to the Offeror's designed/selected/installed insulation systems between conductive parts at different electrical potentials or between an energized part and ground to comply with the solicitation N0002420R4112 Section J Attachment B paragraph 3.3.1.4 and not pre-insulated components (wire, transformer windings, laminated busbar, etc.) that are procured by the Offeror which meet all applicable requirements contained in solicitation N0002420R4112 Section J Attachment B. Any location in the Energy Magazine system that is not in compliance with the requirements of solicitation N0002420R4112 Section J Attachment B paragraph3.3.1.4 would require Navy approval through the Request for Variance process. | |
| 038 | 6/19/20 | RFP, Section C | Page 35, 1.2.1.6 | Modeling and analysis activity as part of the Preliminary and Detailed Design Reports shall include "...e. EMI radiation and susceptibility". The effort involved to produce a model to predict EMI radiation and susceptibility would seem excessive, and its validity questionable. Was the intention to provide a model that predicted conducted emissions and conducted susceptibility? | Solicitation N0002420R4112 Section C paragraph 1.2.1.6 requires the Offerors to include documentation of EMI analysis activity and identify any tools used in the analysis of Energy Magazine conducted EMI and EMI susceptibility. | |
| 039 | 6/19/20 | RFP, Section C | Page 35, 1.2.1.6 | A switching model with fixed time step of 2.5us and can only contain 30 switches is not going to be a full model and will not faithfully reproduce the switching behavior. Would suggest the Government accept across the board the delivery of only average models, rather than requiring a written request and approval during the contract period and/or remove or adjust the limitations on the switching model. We would recommend a time step of no less than 0.5us and switch count limitations removed to allow the appropriate representation of the system. | The requirements as contained in Solicitation N0002420R4112 Section C paragraph 1.2.1.6 remain unchanged. | |
| 040 | 6/19/20 | RFP, Section C | Page 36, 1.2.1.6.1 | Does the GFI regarding detailed analysis methodology around CM include the testing called out in 1.2.1.6.1? It is unclear what the Government's expectation is for DM and CM characterization and if special test facilities and/or equipment will be required. Can the Government further define the effort involved in characterizing DM and CM? | The methods of analysis required by solicitation N0002420R4112 Section C paragraph 1.2.1.6 can be found in articles entitled "Common-Mode Equivalent circuits for Analysis of Grounding Methods in Naval Power Systems" by Brovont and Pekarek (NEJ No. 126-4, Dec 2014) and "Equivalent Circuits for Common-Mode Analysis of Naval Power System" by Brovont and Pekarek, IEEE 978-1-4799-1857-7/15. | |
| 041 | 6/19/20 | RFP, Section C | Page 36, 1.2.1.6.1 | Should we assume that the detailed switching coupled CM and DM model has the same switching model restrictions stated previously (2.5us and max of 30 switches). It is believed these restrictions will not result in a satisfactory model. We recommend a time step of no less than 0.5us (depending on frequency range of interests) and no switch count limitations to allow for an appropriate representation of the system. | See response for question #039. | |
| 042 | 6/19/20 | RFP, Section C | Page 38, 1.3.1.2 | CHIL must be tested prior to PDR. Contractor shall supply the controller HW and SW for CHIL testing. Release for SW coding is an output of CDR. According to the Government's schedule and development approach, how can controller HW and SW be available for CHIL prior to PDR? Can the Government further define the pedigree of HW and SW required for CHIL to appropriately define the expectation for such items delivered within the first several months of the program? | Solicitation N0002420R4112 Section C paragraph 1.3.1.2 has been modified to clarify the requirement. | |
| 043 | 6/19/20 | RFP, Section C | Page 41, 1.4 | 1.4 states "EM shall be tested to its full power level under load". Does this mean that all aspects must be under full power simultaneously putting out 3.2MW to 3 separate loads? Or can each part of the system be tested to full power but not simultaneously? Considerations could be module full power, groups of modules, cabinets, or by function/load. | Solicitation N0002420R4112 Section J Attachment C paragraph 3.2.5 provides the required operating durations and lineups for the baseline output converter configurations. | |

| 048 | 6/19/20 | Given the developmental nature of the CLIN0001 it would seem appropriate for the Government to specify CLIN0006 as a ROM at this stage of the program. Will the Government consider changing CLIN0006 to a ROM for this proposal? | No. | |||
| 049 | 6/19/20 | Section J Att B, Att D, E & F | Page 16, Figure 2, Figure A1 in Att D, E, F | In Section J, Attachment B, Figure 2, the first Energy Magazine building block shows an "AC/AC Line Frequency" block. This block in current shipboard systems would imply a 60 Hz transformer. That same block appears in Section J, Attachments D, E, and F in Figure A1. Additionally, Figure A2 clearly identifies an AC/AC isolated converter followed by an AC/DC isolated converter (assuming the dotted line represents isolation). Is it the intention of the Government to specify the use of 60 Hz transformers, or are those not permitted in any baseline or variant systems? If the Government was not trying to specify a line frequency transformer the block should be represented by one block; an AC/DC isolated converter stage. This seems to conflict with the statement on page 29 of the RFP "All necessary functionality of the baseline and variant inputs/outputs shall be accomplished by higher frequency transformers contained within the Energy Magazine specified volume." | The figures contained in these references contain functionality that may be required depending on the application. The Solicitation N0002420R4112 Section C reference to higher frequency transformer has been removed in A002. | |
