Replace A/C Chillers on M/V Fort Jefferson
Dry Tortugas National Park
1. The implication is that the vessel is three phase power but in the pictures, there are VFD's? I'm assuming it’s single phase 240 in and the VFD generates to three phase power?
Response: We do know that that we have 460 volt 3 phase that enters the ship. It goes through a transformer in which it is knocked down to 220 volt. It is our understanding that the power being supplied to the HVAC system is 220 volt 3 phase.
2. The pictures regarding the raw water manifold looks like two different pictures. It looks like the manifold was cut and adapted to fit from three chillers to two chillers. Is this something that you’re going to need remedied to install three chillers?
Response: The existing manifold will need to be entirely replaced to accommodate 3 chillers. The current configuration only shows two because we removed a chiller and modified the manifold to bypass the space where the middle chiller was located.
