1.0 SCOPE. These Detail Specifications contain the

requirements for dockside repairs to NOAA Ship Oregon II.

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.

2.2. Requirements

2.2.1. References 2.1.1 through 2.1.10 form 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. Some asbestos-containing materials are known to exist

on the ship and generally identified in Reference 2.1.3. The original asbestos survey was performed in 1992. Other report documents have been added based on other asbestos abatement jobs which had been performed on the ship since the original survey.

A copy of the asbestos survey report may be reviewed on board the ship and at the Gulf Marine Support Facility, Port Engineer’s Office, 151 Watts Avenue, Pascagoula, MS. The contractor shall be responsible for all removal, handling, repair, and disposal of Asbestos Containing Materials (ACM) that are identified as ACM, or presumed to contain ACM based on the test results of samples analyzed in the asbestos survey reports.

ACM abatement and removal necessary to perform other contract work in these specifications shall be in compliance with reference 2.1.2.

2.2.3. On a weekly basis (on the day preceding the Weekly

Progress Meeting) provide revised and updated copies of the Production Schedule to the COTR, to reflect the actual work progress.

2.2.4. Schedule, provide and maintain a status report of all

American Bureau of Shipping (ABS) surveyor inspections and technical reviews required by ABS, during the course of the contract to ensure the ship’s ABS Load Line Certification requirements are in compliance. An ABS field surveyor is required to be on site for work items requiring ABS inspections and technical reviews. NOAA will pay ABS directly for their services under a separate purchase agreement.

2.2.5. All Welding, visual examination, hydrostatic testing, air testing, and non-destructive testing shall be in compliance with ABS Rules for Building and Classing Steel Vessels, Surveys After Construction, Part 7, and the ABS Load Line Technical Manual. All contractors performing NDT and hull gauging shall be certified under the ABS external specialists program.

2.2.6. 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 any paint system disturbed while accomplishing work items, in accordance with Reference 2.1.6. Finish coat colors shall match those of the surrounding, unmodified area. Prepare and coat all new aluminum, all existing aluminum surfaces identified to be cleaned and painted, and any aluminum paint system disturbed while accomplishing work items, in accordance with Reference 2.1.7.

2.2.7. Drawings shall be updated only when specified in the

individual work item. All CAD drawings shall be updated in AutoCad 2000. All paper drawings shall be red-lined. The red-line and CAD updates shall include a complete list of new parts used, to the level of detail shown on existing parts lists on the referenced drawings. The Government shall provide either a full size copy of the drawing to be redlined or a copy of the CAD drawing. The updated drawings shall be returned to the COTR prior to the completion of the performance period. 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 are required.

2.2.8. All new equipment and furnishings purchased by the

Contractor for installation on the ship shall be provided with four sets of 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 and prior to completion of performance period. 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.

2.2.9. 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. All operational testing of equipment shall be performed dockside (Dock Trials) prior to any scheduled sea trial.

2.2.10. 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.

2.2.11. All tests and trials of equipment and systems shall be witnessed by the COR, Ship Representatives, ABS as applicable, to ensure compliance with regulatory body requirements to maintain the ship’s ABS Load Line Certification, and to complete all requirements of these specifications.

2.2.12. These Detail 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 the work requirements. When specific details are required, the Government will provide design/detail specifications; this will be more the exception than the rule.

2.2.13. 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 which will be issued in .pdf format with the solicitation. Contractors are advised to perform a field inspection prior to submitting a bid offer. Copies of other ship’s drawings and technical manuals that are not issued with the solicitation will be made available for review during scheduled pre-bid inspections, at the Port Engineer’s office at the Gulf Marine Support Facility, 151 Watts Ave., Pascagoula, MS and during the performance period as needed.
