1.0 GENERAL

1.1 BACKGROUND

The Northeast Fisheries Science Center (NEFSC) operates under the National Marine Fisheries Service (NMFS), a part of the National Oceanographic and Atmospheric Administration (NOAA). The agency’s core mission is the stewardship of living marine resources.

To support ongoing facility resilience, process fluid infrastructure, and reliable laboratory operations, the facility requires a complete replacement and modernization of its salt water pumping system and associated electrical infrastructure. The existing system must be decommissioned to make way for corrosion-resistant equipment capable of surviving a harsh coastal environment.

1.2 SCOPE

The scope of this project is the complete decommissioning of existing system, and procurement, installation, and wiring of a new corrosion-resistant salt water pumping system and its supporting electrical distribution and plumbing infrastructure. The Contractor shall furnish all labor, materials, equipment, transportation, and supervision required to execute the following transitions:

● Removal of legacy disconnects, starters, wiring troughs, wiring, breakers, enclosures and plumbing piping.

● Procurement and installation of a Vanton Chem-Gard® non-metallic horizontal centrifugal pump assembly or equivalent.

● Installation and configuration of four (4) active WEG variable frequency drives (VFDs/Inverters) and associated NEMA 4X enclosures or equivalent.

● Upgrading local field instrumentation, current transducers, and electrical distribution wiring.

● Delivery of required on-site backup components (spares) directly to facility inventory.
