JML #: 9050-9550

RCP#: N4523A19RC23881

Ship/Activity: SSGN-727 Title: Rental Chiller and accessory equipment to support production comfort cooling Place of Performance: Puget Sound Naval Shipyard, Dry-dock #2, Bremerton, WA.

Period of Performance: From June 1, 2019 through September 30, 2019

REFERENCE:

(a) Local Standard Item 099-01NW, General Occupational Safety

1. BACKGROUND: In support of maintenance being conducted on USS MICHIGAN (SSGN-

727) during the MND project availability, PSNS & IMF requires one (1 ea.) portable water chiller unit capable of 150-Ton capacity, air-cooled, with accessory equipment. The chiller will be installed in the weather in the dry-dock basin next to a submarine to provide chilled water (CW) to portions of the ship with widely varying chilled water flow rates and heat loads. The contract shall also include setup, startup assistance, operator training, and all maintenance. Throughout this specification, the completed system, including all components, is referred to as “the chiller”

2. SCOPE: The chiller and accessory equipment shall be delivered and set up by the contractor.

The vendor shall provide training to three government personnel who shall operate the equipment during the rental period and change the chilled water filters as needed. All other maintenance and repairs shall be the responsibility of the vendor. The government will connect electrical power to the chiller and pumps, connect temporary freshwater to the surge tank and connect the supply and return hoses to the government distribution system.

2.1 Chiller supply parameters:

2.1.1 The chiller shall be rated for at least a 150-ton nominal and 150-ton design refrigeration capacity and shall be capable of supplying at least 300 GPM with a pressure loss of 40 psi in the customer loop (i.e. from the chiller CW discharge to the chiller CW inlet). The chiller shall be capable of being operated from no cooling load up to 150-tons continuously where compressors shall automatically come on and off line as required and the automatic recirculation valve shall open to maintain the required minimum flow through the chiller during low flow conditions and close during high chill water demand conditions. The water to be chilled is freshwater.

2.1.2 The chiller controls shall be capable of being adjusted to supply chilled water at a temperature of 42ºF with a temperature difference (Delta T) of 10ºF. The controls shall be capable of being adjusted to maintain the temperature within a 1ºF modulating band between 40 and 50ºF.

2.1.3 Only equipment generating 90 dBA or less when tested IAW ANSI S12.16 is acceptable. The contractor shall identify any product being offered that is certified as a low-noise-emission product per 42 USC 4907.”

2.2 Equipment Requirements:

2.2.1 The chiller shall be air-cooled and electrical-powered, suitable for a 460-volt, 3-phase power supply. The chiller package shall be self-contained so that it is capable of chilling water and circulating the chilled water in the customer’s loop without any additional utilities or equipment once the electrical power supply, freshwater supply, and chilled water supply and return lines are connected.

2.2.2 The required accessory equipment includes, the following so that the package with accessory equipment connected functions as a self-contained chiller once the government-provided utilities are connected and the package is connected to the government distribution system as shown on the attached diagram.

a. Two pumps, 300 GPM minimum at a TDH of at least 115 feet.

b. (10ea) 4” LPA flanged Tee assemblies, (4ea) 4” 90 degree elbows, (1300 ft)

4” hose assemblies, (5ea) 4” LPA flanged isolation valves with 4” LPA flange x 2-1/2 male camlock, (5ea) 4” LPA flanged isolation valves with 4” LPA flange x 2-1/2 female camlock fitting, and (3ea) 4” isolation valves as necessary to connect the accessory equipment to the chiller as shown on the attached diagram.

c. One 500-gallon minimum surge tank with a float-operated valve for freshwater make-up supply and an atmospheric vent.

d. One automatic bypass recirculation valve.

e. Cam Lok to Terminal Lug Pigtail Adapters (25 feet) for electrical connections.

2.2.3 The chiller shall include a strainer or filter which handles the entire chill water flow. There shall not be any bypass around the strainer. The strainer shall be designed for the rated flowrate.

2.2.4 The chiller shall have electric condenser fans which cycle on and off as needed, to accommodate the varying load and varying outdoor temperature.

2.2.5 The chiller unit shall be self-regulating with fully automatic controls, alarms, and indicators so that the chiller package requires monitoring no more than once every three days by the chiller operator.

2.2.6 Required instrumentation: chilled water flowmeter, chilled water inlet and outlet temperature gages, chilled water inlet and outlet pressure gages, and other instruments as necessary to monitor the operation of the unit.

2.2.7 The connected load will consist of cooling coils and industrial equipment, all of which will be cycled on and off. The total load will vary from nearly no load to 150 tons. Each chiller shall include controls and flow components to permit the chiller to automatically accommodate these widely varying loads and flow rates.

It is permitted for the refrigeration equipment in the chiller to automatically cycle on and off to accommodate the varying load.

2.2.8 The inlet and outlet chill water connections shall be 4” LPA with exception of the 4” tee fitting isolation valve discharge shall be 2-1/2” M/F camlock fitting as specified in paragraph 2.2.2.b.

2.2.9 The chiller package shall be suitable for operation in an outdoor marine environment.

2.2.10 The chiller package shall be capable of being operated, continuously, 24 hours per day, without requiring shut down for maintenance, except the chiller may require shutdown to change or clean the chilled water strainers/filters.

2.2.11 The chiller package and accessory equipment shall be constructed to permit lifting by a crane and forklift or mounted on a wheeled trailer and shall comply with the applicable ASME Boiler and Pressure Vessel code.

2.2.12 A backpressure regulator shall be installed as shown in Figure 1 to provide the minimum required chiller flow rate if the flow in the government distribution system is zero. The set point shall be the matching point on the pump curve. The backpressure regulator shall be similar to a Jordan Valve Model 50 or equal.

2.2.13 Hose assemblies shall be 4” with LPA flanges and 25-ft long to be equivalent to Goodall N325 except that hoses installed on the pump suction side shall be non-collapsible rated for full vacuum. Shorter lengths are acceptable to facilitate connecting contractor –provided accessory equipment together shown on the attached diagram.
