About this file
This document provides responses to questions regarding Solicitation Number N4019223Q5003 from the Department of the Navy Naval Facilities Engineering Command for portable boiler rooms. The solicitation requests packaged boiler units with onboard fuel oil storage and compressed air atomization utilizing No. 2 fuel oil for pilots and main burners. The units must have a working pressure of 150 psi and MAWP of around 250 psi. Startup and commissioning of the new boiler units is required, and the vendor must provide a certified technician and inspector. While the solicitation calls for shipping in a 53-foot container, the Port Authority of Guam can accommodate this but special handling coordination will be necessary with a Guam-based logistics company due to size restrictions of 45 feet elsewhere.

RFI QUESTIONS AND ANSWERS ‐
The following is provided in response to a request for information:
QUESTION (Q) 1: 1. What does the government mean by "Unit comes with PA, jurisdictional boiler inspection at completion"? Does this mean you need someone certified to do the inspection of the unit?
Answer (A) 1: Upon completion of fabrication and installation into the shipping container, a certified inspector with local jurisdictional authority will have inspected and certified that all codes and regulations have been satisfied prior to shipment.
Q2: What does the Start‐up and commissioning mean? Can you elaborate more on what is required and needs to be done?"
A2: As a new boiler unit, it is always best to have the supplier of the unit provide a certified technician for the initial Start‐up and boil‐out. There are many steps and settings which need to be verified prior to a light off, sufficient draft, fuel pressure, and burner control settings to name a few. For the initial commissioning usually, the vendor will supply a certified boiler inspector as well. He will witness and verify all safety devises operate as they should also that the fuel air ratios are correct. Authorization or submission of credentials as boiler inspector may need to be provided to Naval Facilities Engineering / BUPV Program Manager.
Q3: What is the MAWP (design pressure) of the boiler?
A3: MAWP should be around 250 psi. as this would reflect the Safety Valve Set Points provided with the units.
Q4: What is the operating pressure of the boiler?
A4: Unit working pressure needs to be 150 psi.
Q5: Ø System design is based on a Cleaver‐Brooks Boiler. CBEX Steam Firetube Boiler 300HP, (460/3/60) 10350lbs/hr output (from and at 212F), fuels natural gas and #2 Oil. Siemens gas train. ∙ Fuel Series:
100 ‐ No. 2 Oil which is it? Natural gas and #2 fuel oil or just #2 fuel oil?
A5: a. We have found that CB units with incorporated burner assemblies operate with the least number of problems utilizing #2 fuel oil for pilot and main burners (Fuel Series: 100‐ No. 2 Oil). Utilizing compressed air for atomization and not high fuel pressures is also more desirable.
b. A Siemens gas train, I believe for the use of natural gas, is not required in this application. As the requested packaged units should have an onboard fuel oil storage Convault.
Q6: If it is #2 fuel oil only how will the pilot be established? Direct spark ignition? Oil pilot? Propane pilot?
A6: As mentioned above, this should be an oil pilot with compressed air, not high fuel pressure, for atomization. Also, of course a spark ignition.
Q7: The solicitation calls for a 53’ shipping container and my logistics company is telling me that the Guam port will not accept a container larger than 45’. Is the co tract flexible on this spec?
A7: The Port Authority of Guam is capable of handling 53’ shipping containers. However, there are special handling requirements which will require close coordination with a Guam based shipping/logistics company.
