1.0 SCOPE 1.1 These Detail 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 ships 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.
1.3 The work items in the repair specification are identified well in advance of the performance period in order meet the contracting lead times. Additional work items (emergent work) may arise during the period between the work package submittal, contract award, or even prior to the start of or during the contract performance period. In accordance with Commerce Acquisition Regulation (CAR) clause 1352.271-72, the Contracting Officer may order additional changes during the contract period of performance to address any additional work items identified as necessary to ensure the intent of the drydock or dockside repair contract is met; that is, that the vessel shall be able to safely perform its mission, that it will meet all habitability requirements and regulatory body requirements, and that such repairs will be timely performed to ensure to the maximum extent practicable that the ship's schedule is not adversely impacted.

20 of 22 MOC-000-1G August 2004 permitted to make in order to meet the minimum underwater clearance requirements. 4.29.3 At no time will the ship transit a waterway which has non-opening bridge or other overhead structure that would cause less than one-foot clearance over the ship's highest projection. In order to permit passage of the ship under bridges or other overhead structures in the waterway, the government will lower masts which have hinged connections for that purpose. However, the government will not remove, and will not permit the Contractor to remove, any part of the ship's structure or equipment for the purpose of providing the required overhead clearance. 4.30 Ship's Moorings. Whenever the contract requires work to be performed at the Contractor's facility, the Contractor shall provide adequate pier or dock space acceptable to the Contracting Officer for safely mooring the ship. The following requirements and restrictions apply: 4.30.1 The facilities and services shall be sufficient to permit the Contractor to comply with all other requirements of the contract. 4.30.2 Contract award is based, in part, on information provided by the Contractor during the pre-award survey regarding the pier or dock facilities which will be used to moor the ship. Unless specifically approved in writing by the COTR, the ship shall not be moored at any pier or dock space other than those proposed during the pre-award survey. 4.30.3 Shifting of the ship from one mooring berth to another causes disruption of services to the ship and interferes with work and schedules of the crew. Unless specifically approved by the Contracting Officer, no more than one mooring shift (drydocking and refloating excluded) of the ship shall be made during the contract period. a. When shifting of the ship is required, the COTR shall be given a minimum of three days advance notice of the proposed shift. b. Except when drydocking and refloating the ship, all shifting of the ship shall be performed only during regular work days and hours. 4.30.4 All mooring spaces to be used by the ship shall be under the complete and legal control of the Contractor. If the Contractor proposed to use any mooring space which is not owned by the Contractor, a legally binding lease or agreement must be signed by the owner which clearly gives the Contractor complete control of the mooring for the entire period of the contract, including any time extensions which may be approved by the Contracting Officer. A copy of the agreement will be required to be submitted as part of the pre-award survey.

4.31 Disassembly and Inspections. Whenever equipment, machinery, systems, or other system components are required to be disassembled, opened or overhauled, the Contractor shall complete all disassembling and inspections during the first 25-percent of the work performance period. All tanks required to be opened shall also be opened and gas-freed during the first 25-percent of the work performance period. No time extension of the work performance period will be granted for delays caused by the Contractor's failure to comply with this 25-percent time requirement. 5. NOTES. 5.1 The requirements and provisions of this specification are additions to or amplification of the requirements and provisions set forth in other specifications, solicitation, or procurement documents. In the event a conflict should occur, the requirements of the other documents take precedence over those contained herein.
