STATEMENT OF WORK (SOW)

Milford, CT Laboratory Salt (Sea) Water Pump and Electrical Infrastructure System Upgrade

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 Milford Laboratory and the Northeast Oyster Breeding Center’s 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. The scope of this requirement is directly tied to the success of the Oyster Breeding Center’s spawning cycle and research missions. Due to the severe operational impact of any delay, the Government requires strict adherence to the deliverables schedule.

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 (Two spare impellers, one for each pump model) directly to facility inventory.

1.3 OBJECTIVE

To safely remove legacy infrastructure and deliver an operational, highly reliable, and corrosion-resistant salt water pumping system that offers precise local motor control for the Main Building at the Milford Laboratory.

2.0 SPECIFIC REQUIREMENTS / TASKS

2.1 Critical Sequence of Operations (reference section 9.0 Deliverables)

Due to the severe operational impact of current seawater system, the Contractor MUST adhere to the following mandatory sequence of execution:

● Phase 1 (Procurement): The immediate order of the WEG VFDs and Vanton Pump assemblies to be delivered within 4 weeks of NTP.

● Phase 2 (Pre-Demolition Verification): The Contractor shall not initiate any legacy demolition (Task 2) or shut down the existing pumps until all new VFDs, pump assemblies, and critical electrical components are physically on-site and verified by the

COR.
