1.0 SCOPE. The National Oceanic and Atmospheric

Administration (NOAA) operates a fleet of research vessels that supports research and mapping for the National 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.

These Detail Specifications contain the requirements for dockside repairs and modifications to the NOAA Ship Gordon Gunter.

2.2. Requirements

2.2.1. Reference 2.1.1 forms a part of these Detail

Specifications. All provisions and requirements contained therein are applicable to all work items, including all additional work items which are authorized by the Contracting Officer.

2.2.2. References 2.1.2 and 2.1.3 are amplifications of the

requirements contained in reference 2.1.1 sections 4.17 and 4.21.

2.2.3. References 2.1.4 through 2.1.8 will be available for review during scheduled pre- bid inspection and during the performance period of the contract. The general arrangement drawings are the original

Ocean Surveillance Ship T-AGOS 13 class drawings produced when the ship was built. Modifications to the ship after re-activation in 1998 for NOAA’s operations, and conversion in 1999 to meet National Marine

Fisheries Service (NMFS) requirements, are not reflected in these arrangements. Some of the drawings and information provided in references 2.1.6 through 2.1.11 reflect some of the ship’s arrangements and construction changes since reactivation as a NOAA vessel. Contractor shall be responsible for verifying all current configuration, construction, and arrangement changes, as necessary, to comply with and perform the work requirements of these specifications.

Contractors are encouraged to review ship’s drawings and to perform a field inspection of the ship and her equipment prior to submitting a bid proposal.

2.2.4. Ship’s drawings and technical publications may be borrowed during the performance period. All reference materials borrowed by the Contractor shall be signed for, and then returned to the COTR after no further use of the reference materials is required.

2.2.5. Provide and maintain a status report of all American Bureau of Shipping (ABS) inspections and technical reviews required by ABS, during the course of this contract, to ensure the ship’s ABS certification requirements are in compliance. Submit weekly ABS status reports to the COTR, along with the preliminary progress reports.

2.2.6. All visual examination, hydrostatic testing, and non-

destructive testing shall be in accordance with ABS Rules for

Building and Classing Steel Vessels, Survey After Construction 2005, Part 7. All contractors performing NDT and hull gauging shall be certified under the ABS external specialists program.

2.2.7. Provide revised and updated copies of the production

schedule to the COTR as required to reflect actual work progress.

2.2.8. All new equipment and furnishings purchased by the

Contractor for installation on the vessel shall be provided with factory supplied technical manuals, or data sheets, complete with parts listings. Faxed copies of this information are not acceptable.

This documentation shall be turned over to the COTR after installation is completed. Equipment technical manuals shall provide detailed information necessary to operate, maintain, troubleshoot, and repair the equipment. The manuals shall include detailed procedures for disassembly of equipment, parts lists, drawings, inspection criteria, troubleshooting, and test procedures. Provide four paper copies of each manual, plus one electronic copy in Abode Acrobat .pdf format.

2.2.9. All inspection, test, and quality reports shall be

submitted to the COTR in Microsoft Word electronic software formats, in addition to providing hard paper copies.

2.2.10. Weigh all materials and items removed, installed, or

relocated on the ship.

Provide a summary report to the COTR indicating the total weight in pounds of items and a breakdown of their locations by space, deck, frame, distance from centerline, and height above the deck. Reference

2.1.7 will be provided by the COTR for the Contractor to identify, record, and document all weight changes for submitting the summary reports. 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.

2.2.11. 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.l. Finish coat colors shall match those of the surrounding, unmodified area.

2.2.12. 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 otherwise specified, provide a minimum of two working days’ prior notice for any equipment operations.

2.2.13. All new and disturbed machinery and services shall be operated for a period sufficient to indicate satisfactory performance, but not less than one hour, after all adjustments and deficiency corrective actions have been made, without further adjustment.

2.2.14. Provide manufacturer’s technical representatives where required in the individual work items, to witness and to provide technical guidance during operational testing of equipment and systems. All tests and trials of equipment or systems shall be witnessed by the COTR, ABS, and/or USCG as applicable, to ensure compliance with regulatory body requirements to maintain the ship’s

ABS class certification, and to complete all requirements of these specifications.

2.2.15. 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.

2.2.16. 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.

Copies of drawings and technical manuals not included herein may be made available for review during any scheduled pre-bid inspection and during the performance period. Contractors my review available drawings and technical manuals on board ship or at the Port Engineer’s office at NOAA’s Gulf Marine Support Facility, 151 Watts Ave., Pascagoula, MS.
