Part A (Design-Bid-Build), the ship support services, included piping distribution systems for chilled water, nitrogen, high pressure air, oxygen, and propane, and installation of exterior electrical and telecom/data services, and included the installation of ship support services piping distribution systems totaling over 16,000 linear feet. This work also included the removal and replacement of existing feeder circuits from the existing Substation B to Drydock 2. Substation B switchgear was expanded and new telecommunications and SCADA were also installed.
Part B (Design-Build) included a 23,000-square-foot central utility plant that holds major equipment, including electrical switchgear, chilled water pumps, air cooled chillers (3 each), high pressure air compressors (2 each), nitrogen tanks, and air receivers, and has space for shipyard-provided portable emergency generators, chillers, and high pressure air compressors. The new utility plant included a CMU building with pre-cast roof planks and a fenced yard area.
