1.0 SCOPE

1.1 The National Oceanic and Atmospheric Administration (NOAA) operates a fleet of 16 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 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.

1.2 The pipe and valve repairs are identified well in advance of the performance period in order meet the contracting lead times. 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 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.

1.3 These Detail Specifications contain the requirements for pipe repairs for NOAA Ship Okeanos Explorer.

2.0 GENERAL

2.1 References

2.1.1 Drawing No. OE-601-101, “NOAA Ship Okeanos Explorer General Arrangement.”

2.1.2 NOAA Form 57-17-09 – NOAA Hot Work Permit

2.2 Requirements

2.2.1 Some of the ship’s drawings have not been updated to reflect modifications to the ship during activation and conversion in 2007. These drawings and reference documents are for planning purposes only. Actual shipboard configurations and conditions may be different from what is listed. 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 and expected to review ship’s drawings and to perform a field inspection to inspect the locations and shipboard conditions where services are to be performed aboard the Okeanos Explorer prior to submitting a bid proposal. This inspection should satisfy potential contractors regarding all general and local conditions, (including locations, interferences, tolerances and necessary “work-arounds, etc)that may affect the cost of contract performance, to the extent that the information is reasonably obtainable. In no event shall failure to inspect the sites constitute grounds for a change order or claim after contract award.

2.2.2 Ship’s drawings and technical publications may be borrowed during the performance period. It would be preferable for the contractor to make copies of these drawing and technical publications if their intended use will be outside an office environment. All reference materials borrowed by the Contractor shall be signed for, and then returned to the COR after no further use of the reference materials is required.

2.2.3 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.

2.2.4 At the request of the COR, the contractor shall have daily production meetings with trade supervisors and the COR to discuss progress, milestones, labor staffing levels and other project issues (at no additional cost to the Government).

2.2.5 Contractor shall clean up all production areas, sweep up messes, clear all trash and debris and roll back all lines and leads at the end of each shift. All overspray shall be removed and any areas damaged by media blasting shall be sanded and repainted to match surrounding area.

2.2.6 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. Crew availability is generally limited to the hours of 0800 and 1500 local time, Monday through Friday. Unless otherwise specified, provide a minimum of two working days’ prior notice for any equipment operations or system tag-outs.

2.2.7 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.

2.2.8 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.

2.2.9 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 may review available drawings and technical manuals on board ship.

2.2.10 Maintenance of ABS Class and Certificates

2.2.10.1 All ABS rules required to maintain the ship’s Class and Certificates shall be adhered to by the contractor. This includes all rules for material, fabrication, quality control, inspection, and ABS on-site survey of work.

2.2.11 In addition to the contractor’s requirements for hotwork and firewatches – Firewatches for hotwork shall be required. Additionally, the contractor is required to fill out, maintain and comply with reference 2.1.2 (NOAA Hot Work Chit) for all hotwork completed on the ship.

2.2.12 The Ship’s crew will empty all tanks to the lowest point possible using the ships systems. All remaining fluid in the tanks that must be removed by the contractor to complete the tasks associated with these specifications will be the responsibility of the contractor at no additional cost to the Government.

2.3 Quality Assurance

2.3.1 All welders performing work aboard the vessel shall be certified and only perform welding or brazing for processes and filler materials in which they are certified. A list of all welders and their respective certifications who will be performing work aboard the vessel during the period of performance shall be provided to the COR within 3 days after the beginning of the period of performance.
