(1) Statement of Requirement HML Seawater Pumps - Amendment 0002.pdf

Statement of Need Brand Name or Equal to Fybroc Pump Assembly, Power frame, Motor, Parts and Installation

Objective: Acquisition of two (2) new Fybroc or equivalent Pump assembly, Motor, Parts, and Installation

Background: The seawater system at the Hollings Marine Lab provides a continuous supply of seawater for NOAA and four other partner institutions. This seawater is integral in the life support of thousands of marine species used by NOAA and the partner organizations. Initially, four Fybroc fiberglass self-priming centrifugal pumps were used for pumping seawater; the system requires two that are in operation, with the other two being backups. Currently, two of the pumps have been removed from operation due to multiple part failures, and parts have been salvaged to keep the other two pumps operating. Recently, one of the 18-year-old self-priming pumps in operation broke down, and a teardown diagnosis revealed that the bearing in the power frame was damaged beyond repair. Additionally, the fiberglass impeller, back-plate, volute insert, and seal were worn beyond repair and were replaced with less damaged used parts from another damaged pump. This leaves the seawater system without the necessary backups for sustaining the critical life-support for several thousand marine species, plus one of the two operational pumps has slightly damaged parts and is operating at a reduced capacity. There are no more usable parts from the two non-operating pumps that can be salvaged for any other repairs to the two operating pumps. Therefore, the Contractor shall furnish and deliver two new complete Fybroc pump assemblies and motors so we can replace the current damaged pump that is in operation and have one backup.

Specifications: The Contractor shall furnish, deliver, and install Two (2) Brand Name or Equal to Fybroc 1600 Pump Assembly w/15hp motor which shall meet the following specifications and salient characteristics:

Installation

Site Visit:

Offerors are strongly encouraged to conduct a site visit to review all existing conditions affecting the requirements in this statement of work, and to familiarize themselves with site conditions for purposes of formulating quotes. It is the Contractor’s responsibility to confirm existing conditions and evaluate requirements listed in the Statement of Work herein. Failure to determine existing conditions will not be considered a basis for granting additional compensation. Offerors wishing to schedule a site visit shall contact the below Government Technical POC:

1. Pump & Piping Mechanical Scope

A. Match existing baseplate and coupling layout

The pumps sit on grouted steel bases with Fybroc-style spacer couplings. New pumps must be supplied with the same footprint, anchor-bolt pattern, and coupling type (including spacer and guard) to avoid extensive civil and mechanical rework.

B. Alignment & vibration isolation

a. Grout pads must be cleaned and level to < 0.005″/ft before grouting the new base.

b. Shall provide shims and grout under each sole plate.

c. Shall install flexible-element couplings per manufacturer’s specs and perform laser-alignment to within

0.003″ TIR.

d. Shall add or reuse the neoprene (or spring) vibration isolators under the feet if present.

C. Valve & strainer provisions

Each pump is isolated by a full-port valve on both the suction and discharge sides (either actuated or manually).

Contractor shall:

a. Verify valve type/rating and re-use or replace gaskets (chlorine-resistant).

b. As required, install a suitable suction strainer or diffuser upstream of each pump to protect the impeller from debris.

c. As required, provide a check valve (or triple-duty valve assembly) on the discharge side to prevent reverse flow and allow safe isolation.

D. Material compatibility & coatings

a. All wetted parts (volute, impeller, shaft) must be bronze, 316 SS, or engineered FRP rated for seawater.

b. Shall re-coat steel bases and exposed piping with marine-grade epoxy to inhibit corrosion.

c. Shall consider sacrificial anode or cathodic protection if piping spans sections of dissimilar metallurgy.

2. Electrical & Controls

A. Motor starter and wiring mailto:richard.sparkman@noaa.gov mailto:ronald.skelly@noaa.gov

On-site fused disconnects labeled “MSP-1” and “MSP-2” supply power to these pumps.

Contractor’s electrician must:

a. confirm voltage/phase (460 V/3/60 Hz) and full-load amperage from motor nameplate.

b. Match or upgrade over-current protection and conduit seals to NEMA 4X in this coastal environment.

c. Re-terminate control-circuit leads (flow switches, motor starters, safety interlocks) into the existing junction boxes.

B. Integration with BAS or local interlock

The seawater pumps are integrated into the building automation system for sequencing and alarm purposes.

Contractor must:

a. Confirm the flow-switch, pressure-transmitter, and level-sensor locations on the suction/discharge headers.

b. Reconnect these instruments and verify their calibration.

c. Witness a complete start/stop sequence with the control vendor to ensure the new pumps “hand-off-auto” correctly.

3. Site & Environmental Considerations A. Temporary bypass/continuity of service

It may be required to avoid shutting down all seawater services to install a blind flange or temporary jumper on Pump #1 while #2 is out, and vice versa. Confirm the remaining pump(s) can carry the baseline flow.

B. Flood and splash protection

The pad sits at grade on the waterfront—Contractor shall confirm adequate slope/drainage and consider adding a lip or curb to keep storm surge from overtopping.

C. Salvage and storage

The contractor shall maintain the old pumps to the maximum extent possible without damage during disassembly. We will store the old pumps and provide dry, sheltered storage space, labeling all parts (impellers, seals, and couplings) for future reuse or inspection.

4. Permitting & Regulatory A. Acquisition & salvage clauses

Since these are Government-owned assets, the contractor must comply with DFARS/FAR clauses for equipment removal, custody, and potential re-installation of old pumps or parts for spare-parts inventory.

5. Unforeseen Issues to Watch For:

A. Flange face corrosion or misalignment

The current white-painted PVC/FRP piping exhibits visible pitting; flange faces may be out of tolerance and require re-machining or replacement spool pieces.

B. Hidden piping supports

Some branch take-offs under the pad are supported by buried steel posts; excavation for removal may uncover corroded supports needing replacement.

C. Instrument tubing deterioration

The clear plastic tubing for level and flow sensors is UV-brittle; plan to replace rather than reuse.

D. Coupling guard interference

The bright orange coupling guards fit tightly; however, new pumps may have slightly different shaft-center spacings, and guards might require offset brackets.

E. Control signal incompatibility

Verify the BAS analog/digital I/O matches existing Metasys mapping before final installation. (This most likely does not apply, but mentioning just as a precaution.)

Delivery Date: Delivery and installation shall be completed no later than November 14, 2025
