Week/Month Ending April 30, 2021
On Monday, 03/29/2021 and throughout the month of April, excavation and preparation work continued for the installation control panels, feeder lines, rough outs for all of the electrical equipment including switch gear, station power, transformers and the 2 CAT G3520 engine generators.
We met with our mechanical engineering contractor to review the material list and schedule the rough in plumbing, including building drain, oil & water separator, health & safety and water main installation prior to pouring the concrete housekeeping pads and floor.
We selected and ordered the water cooling tower. We analyzed cooling tower configurations and manufacturer designs for sizing and matching of heat loads to the condensing heat exchanger. We also compared winterization of cooling tower using an elevated design that drained the cooling tower sump to winterization utilizing an immersion heater. The decision was to utilize the immersion heater system. This simplified the cooling water circuit by using the cooling tower sump and circulating pump for both the cooling tower and the condensing heat exchanger.
We reviewed safety and code requirements for engine room design utilizing a natural gas leak detection system. We reviewed startup procedure with Caterpillar for interfacing the engine fuel train with the engine controller to prevent an engine start up when there is a pressure drop in the fuel supply. We also reviewed location and layout of remote radiators and cooling tower with our mechanical engineering contractor to ensure there is no interference with the installation of gas lines being installed by HG&E.
The remote, high resolution cameras, NVR System and wireless communication equipment has been installed. They began real time, monitoring and motion sensing recording on 04/15/2021
We met with our acoustical design engineers and approved final designs of the sound attenuated room and mezzanine.
We approved final design layouts and location layouts of remote radiators and cooling tower with our mechanical engineering contractor to ensure there is no interference with the installation of gas lines that will be installed by HG&E.
Two 50′ “high – cube” open top storage containers were delivered on 04/14/2021 that will store, on-site the 2 CAT G3520 engine generators, prior to installation and commissioning.
We had all of the rebar and forms necessary for the pouring the concrete housekeeping pads delivered on 04/22/2021. It is expected that the 2 “housekeeping” pads (14″ pour) for the CAT G3520Cs will begin as soon as possible.
The 2 CAT G3520 engine generators were delivered and off-loaded into secured open top, high-cube containers on Thursday 04/22/2021 at 2:00pm.
All excavation work for the rough in plumbing, including building drain, health & safety and water main installation prior to pouring the concrete housekeeping pads and floor has been completed. All rough plumbing was inspected on Friday, 04/23/2021.
ESG met with Milton CAT to have them perform on-site to inspection of the 2 CAT G3520 Engine Generators and inspect all conduit runs and engine generator “stub-ups” prior to the pouring of the house keeping pads.
The scheduled delivery of the 2 remote radiators will be on or before May 5, 2021.
We are still waiting on a date for the delivery Selective Catalytic Reduction Systems (SCRS).
This is a very fluid environment with respect to a multitude of technical and engineering designs that are necessary to meet a variety of requirements for producing and selling electricity, manufacturing distilled water and capturing CO2.
If anyone has any questions or concerns, we kindly ask that you contact ESG at (413) 272 – 2135.
