1. SCOPE

1.1. These Performance Specifications contain the requirements for drydock repairs and modifications to NOAA Ship Oscar Elton Sette .

1.2. The National Oceanic and Atmospheric Administration (NOAA) operates a fleet of research vessels that supports research and mapping for the National Marine Fisheries Service, National Ocean Service, Office of Atmospheric Research and the National Weather Service, as well as provides support to other Federal agencies. These research missions are time sensitive and therefore the data must be collected at specific times during the sailing season to be meaningful. At the end of each sailing season the vessels enter a repair period (drydock or dockside) to address repairs that have been previously identified, perform upgrades to mission systems or ship systems that either extend the life of the ship or provide new data collection capabilities or for safer operations of ships systems as well as address any emergent work that would adversely affect the ship's ability to safely perform its mission on schedule, while meeting all regulatory body requirements (American Bureau of Shipping and United States Coast Guard) and all habitability requirements, including any that may be required as a result of contracts for personnel to augment ship staff.

The contractor may use their own weight report form for documenting weight changes. All the information required must be tracked and documented on any form provided.

2.4.13. Unless otherwise stated in the individual work items, prepare and coat all new steel, all existing steel surfaces identified to be cleaned and painted, and all paint systems disturbed while accomplishing work items, in accordance with Reference 2.1.4. Finish coat colors and paint type shall match those of the surrounding, unmodified area.

2.4.14. Ship’s force will maintain a minimal presence during

accomplishment of work to these specifications. Their availability to operate ship’s equipment will be limited.

Unless specified elsewhere in the detail specification, all replacement parts shall be new parts from the OEM.

2.4.19. These Detailed Specifications are a combination of

“performance specifications” and “design specifications.”

Whenever possible, the Government has provided performance specifications, giving the Contractor the opportunity to accomplish the work requirements as best as he or she sees fit, while providing a fully functional repair and/or equipment/system installation in accordance with all work requirements. When specific details are required, the Government will provide design/detail specifications; this will be more the exception, than the rule.

2.4.20. Frame numbers and space names are derived from ship’s drawings. All equipment changes and space modifications over the ship’s life span may not all be reflected in the referenced drawings. Contractors are encouraged to review all referenced drawings and to perform a field inspection of the ship prior to submitting a bid.
