NOAA Fleet Motor and Generator Support

1. Scope

1.1. Collect predictive maintenance/condition monitoring data on large propulsion motors and ship service generators in the NOAA fleet.

1.2. Provide data trending, cleaning, motor/generator service

1.3. Ability to provide engineering analysis, testing, cleaning, re-wind service, documentation, and components required to maintain the functionality of the system and for regulatory annual surveys.

2. Background

2.1. The National Oceanic and Atmospheric Administration (NOAA) operates a fleet of 15 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 ship’s systems as well as address any emergent work that would adversely affect the ship’s 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.

4. Government Furnished Material

4.1. None

5. Requirements

5.1. Except as otherwise specified, the contractor shall provide all labor, material, services, tools, supervision, and technical expertise needed to accomplish the work required by this specification within the specified time limits. All repairs shall be made according to the manufacturer’s specifications, clearances, tolerances, and procedures. Further, all work shall be accomplished in accordance with ABS and USCG requirements; refer to reference 3.1, Rules for Survey After Construction 2018 Part 7, Chapter 6, Section 2,

3.1.3 (b) Main Propulsion apparatus.

5.2. Machine inspection and shop work should be performed by a firm that is a member of the Electrical Apparatus Service Association (EASA), and must adhere to the EASA standards and procedures, including reference 3.3. If not contractor is not a member of

EASA, please explain how industry standards are implemented.

5.3. Please provide process related to use of liquid solvents of any kind.

5.4. Do not use ship’s service air for blowing out and cleaning of machines as this has high moisture content. Air from scuba air flask is acceptable.

5.5. Do not use silicone or silicone based insulations, cables, paints, varnishes, laminates, tapes, compounds, rubber, greases, or other silicone products within the interior of the machine. Ensure that mechanics using protective hand creams containing conductive or silicone materials do not handle internal machine parts, as even small amounts of silicone materials will cause greatly increased brush wear.

5.6. Use extreme care to ensure that foreign objects do not enter the machine. A small bolt, nut, or other object in the air gap may cause significant damage requiring weeks to repair at the Contractors’ expense.

5.7. Adhere to the requirements, cautions, and warnings stated in the machine manufacturer’s instruction books.

5.8. Use materials and replacement parts that are new and of equal or superior quality to the materials and parts used by the machine manufacturer.

5.9. After each phase of the cleaning and testing, and whenever any condition is noted which needs correction, contact the COR for guidance before closing machine. At the completion of all work submit a written condition report to the COR which includes all inspection results, test results and measurements, along with recommended corrective actions needed to restore machines to a condition of reliability equivalent to a new machine.

5.10. If brush replacement is required for DC motors, or shaft grounding systems, the entire brush set shall be replaced. Use only machinery manufacture’s recommended brushes with consideration to size, material, quality, spring, and grade. Brush set shall be replaced if worn down to one quarter of original length. New brushes shall be properly seated following machinery manufacturer’s instructions. Do Not Use Emery Cloth.

5.11. Protect all open machines with temporary covers during periods when no work is actively in progress on the machine internals.

5.12. After each phase of the cleaning and testing, and whenever any condition is noted which needs correction, contact the COR for guidance before closing machine. At the completion of all work submit a written condition report to the COR which includes all inspection results, test results and measurements, along with recommended corrective actions needed to restore machines to a condition of reliability equivalent to a new machine.

5.13. Typically NOAA performs repair periods during winter months as such it is possible that several ship visits would be scheduled in a 30-60 day window. Describe ability to perform multiple ‘Annual System Inspection’ in any of the homeport locations identified.

5.14. Annual System Inspection
