Statement of Work For Instrument Cages

Background

The Department of Commerce (DOC), National Oceanic Atmospheric Administration (NOAA), National Marine Fisheries Service (NMFS), Chesapeake Bay Office (NCBO) requires instrument cages to deploy subsurface sensors on data-buoys. The Chesapeake Bay Interpretive Buoy System (CBIBS) employs subsurface sensors to monitor currents and water conditions in the Chesapeake Bay. These instruments are suspended beneath data-buoys by a stainless steel instrument cage in through holes in the buoy hull. CBIBS is implementing a new buoy design with smaller through holes, requiring new instrument cages.

Objectives

Obtain eighteen (18) instrument cages for the deployment of sensors.

Scope

Manufacture and deliver instrument cages in accordance with the attached technical requirements.

Tasks

The contractor shall:

· Manufacture and deliver eighteen (18) instrument cages capable of attaching subsurface oceanographic sensors to NCBO’s next generation of in-situ observing platforms.

· These instrument cages shall be in precise accordance with the provided technical specifications to ensure compatibility with NCBO’s observing platforms.

Delivery

The contractor shall arrange to ship the items to the NCBO field operations facility.

Government‐Furnished Property Government property will not be furnished. Security Considerations Special security considerations are not required.

Travel

Travel is not included in this contract.

Special Material Requirements

The instrument cages shall be constructed from a material and using methods which can resist perpetual exposure to seawater and repeated accumulation of marine life. These materials are listed in the associated technical specifications.

Other Unique Requirements and Considerations

None

Place of performance

The items shall be manufactured at the facility of the contractor’s choice.

Period of performance

The period of performance will be one month following the contract award.
