1. SCOPE
1.1 These Detail Specifications contain the requirements for
dockside repairs on the NOAA Ship Thomas Jefferson (formerly USNS Littlehales T-AGS 52).
1.2 The National Oceanic and Atmospheric Administration (NOAA) operates a fleet of research vessels that support research and hydrographic mapping for the National Marine Fisheries Service, National Ocean Service, Office of Ocean and Atmospheric Research, and National Weather Service, as well as provide maritime support to other Federal agencies. These research missions are time sensitive and therefore the data must be collected at specific times during the year to be meaningful. At the end of each vessel’s sailing season, the vessel enters a repair period (drydock or dockside) to address previously identified repairs, perform upgrades to mission or vessel systems that will provide new data collection capabilities, extend the life of the vessel, or provide for safer operation of the vessel’s systems as well as address any emergent work that would adversely affect the vessel’s ability to safely perform its mission on schedule, while complying to all regulatory body requirements (American Bureau of Shipping and United States Coast Guard) and habitability requirements, including any requirement that may arise as a result of contracts for personnel to augment ship staff.
1.3 The work items in this repair specification were identified well in advance of the performance period in order to meet contracting lead times. Additional work items (emergent work) may have arisen following submission of the original work package but prior to award of the contract, after award of the contract but prior to start of the performance period or even during the contract performance period. In accordance with Commerce Acquisition Regulation (CAR) clause 1352.271-72, the Contracting Officer may modify the contract during the Period of Performance to address any emergent work as necessary to ensure the intent of the drydock or dockside repair contract is met; that is, the vessel shall be able to safely perform its mission, the vessel will meet all habitability and regulatory body requirements, and such repairs will be performed timely to ensure, to the maximum extent practicable, that the vessel's schedule is not adversely impacted.
