1. GENERAL

1.1. BACKGROUND

NOAA’s Pacific Marine Environmental Laboratory (PMEL) is a federal laboratory that makes critical observations and conducts groundbreaking research to advance our knowledge of the global ocean and its interactions with the earth, atmosphere, ecosystems, and climate. Its main office is located at NOAA’s Western Regional Center in Seattle, WA.

PMEL owns and operates the R/V SP Hayes; a 38’ aluminum work vessel used exclusively in the Puget Sound region and Lake Washington. The vessel is primarily used to deploy and test data collection platforms including: buoys, subsurface instrumentation, and autonomous vehicles. PMEL acquired the vessel from the Army Corps of Engineers over 20 years ago. Since acquiring the vessel it has undergone several modifications to increase its functionality for PMEL missions.

Vessel specifications and other details are as follows:

● Year built: 1976

● Manufacturer: Dura Craft, Monticello, AR

● Length overall: 38’ 10”

● Beam: 12’ 10”

● Hull Material: Aluminum

● Superstructure Material: Aluminum

● Engines: Twin 671 Detroit Diesels

● Single station control in main cabin of vessel

● Stern mounted A-Frame

○ 96” of clearance between deck to center padeye

○ 48” of overboard clearance

○ Base width 126”

○ Safe working load 3,000 lbs

1.2. OBJECTIVE

1.2.1. Repair the R/V SP Hayes to a condition that ensures its continued reliability, safety and utility to the lab and its partners until 2031.

1.2.2. Modify existing structures and add features that enhance the vessel's primary mission capabilities including deployment of buoys and instrumentation.

1.3. SCOPE

1.3.1. This Performance Work Statement (PWS) contains the general requirements for work performed by the Small Vessel Repair Contractor (Contractor) for the Pacific Marine Environmental Lab’s R/V SP Hayes. These general requirements apply to all work items contained in this contract including care of the vessel, sea trials, and services provided to the vessel during the contract.

1.3.2. Work under this contract will be performed at the Contractor’s facility. The Contractor is responsible for transport between the NOAA Facility and the Contractor’s facility. Upon completion, NOAA will conduct acceptance testing at the Contractor’s facility.
