Statement of Work and Specifications for Hull Repairs to NOAA R/V

Murrelet (F4103) and R/V Siliqua (F4101) Requisition 143041-25-0005

Background:

The NOAA Fisheries Service in Hammond, Oregon operates NOAA R/V Murrelet (F4103) and NOAA R/V Siliqua (F4101). These are 41’ ex-USCG Utility Boats. The vessels have numerous deep pits in the interior and exterior hull and struts caused by corrosion. These areas and struts require replacement prior to the vessel going back into service March 01, 2026.

Prospective Contractors are strongly encouraged to inspect the vessel to understand the entirety of the work being requested. The vessels may be available for inspection in Hammond, Oregon. Access is by appointment only, please contact Brian Fite (503.994.5062) for arrangements.

Place and Period of Performance:

To accommodate regular inspections by NOAA personnel based in Astoria, Oregon and address vessel transportation logistics, the work must be performed in the Lower Columbia River Region, within 200 miles of Astoria, Oregon. The preferred worksite is the NOAA facility at 200 Lake Drive, Hammond, Oregon, though an alternate facility may be considered. Due to height restrictions, the vessel will be transported via waterway only, and the contractor will be responsible for any transportation required from the waterway to the alternate facility. Work is to be completed within the agreed timeline, and not later than 01 September 2025. Completion prior to 01 August 2025 is strongly preferred.

Delivery is contingent on safe weather conditions as determined by NOAA personnel.

200 Lake Drive Hammond, OR 97121

Work Items R/V Murrelet:

1. Remove any interferences and crop out sections of the box skeg as required to gain access to hull plating listed below. Note: The box skeg may have been internally flow-coated with a corrosion inhibitor. See Welding and Allied Processes for specific requirements for working in this area.

2. Crop out and renew approximately 60” X 144” section of 5/16” 5086 aluminum hull plating.

This section spans the keel and extends athwartships to the chine on each side, and fore-aft from 4” aft of FR 11 to the stern.

3. Remove, construct and install new Struts and ⅜” doubler plate ensuring proper alignment, including replacing stern tube bearings and strut bearings. Confirm strut alignment using Optical Scope Alignment or other industry standard procedure. The alignment inspections shall be witnessed by the NOAA personnel. Blueprints for struts provided by NOAA.

4. Renew cropped out section of skeg with .25” 5086 aluminum plate. Welding procedure shall be completed in accordance with references listed above for single sided welding.

5. Perform a liquid-penetrant inspection of the root pass and final pass of all welds and filler welds in watertight boundaries, including bulkheads, shell plate, and frames, at or below the main deck level. The inspections shall be witnessed by the NOAA personnel.

6. A pressure test of the skeg and strut shall be performed and witnessed by the selected contractor prior to any work. Pressure test skeg and strut upon completion of repairs via the existing test fitting. Skeg shall maintain 2 psig of air pressure for a minimum of 10 minutes. There shall be no pressure drop during that time period. Repair all deficiencies and retest until correct. The Contractor shall use a regulator and gauge to conduct the test which shall be calibrated to the proper scale and range to accurately measure the 2 psig air pressure. To prevent over pressurizing the skeg, the test rig shall incorporate a safety relief valve set at no more than 4 psig. The inspections shall be witnessed by the NOAA personnel.

7. Restore all existing coating systems which are affected during performance of work. See Painting for specific requirements.

8. Restore any interferences previously removed.

9. A final shaft alignment shall be performed by contractor within manufactures tolerance and witnessed by NOAA personnel to confirm no additional vibration from the above work.

Sketch shall include adjacent framing members, nearby penetrations, and scantlings of the structure. Radius corners shall be used at all corners to facilitate reinstallation. A description of the proposed restoration configuration, with material and welding details, and a narrative justification for cutting the opening shall be provided. The Contractor shall proceed with the access cut only after NOAA approval.

4. Protective Coverings.

a. Prior to starting work on interior spaces, protect the decks and deck coverings of spaces in which contract work is to be performed and spaces through which workers will traverse by covering the decks and deck coverings with temporarily fitted heavy plastic, cardboard, plywood or particle board.

b. Protect all compartments, machinery, equipment, furnishings, vent terminals, insulation, glass, cables, piping systems, coatings, structures, and other boat components from damage and from entry of dust, dirt, grit, sand, and other foreign particles.

Re-preparation due to oxidation bloom shall be the responsibility of the Contractor at no charge to the Government.

b. All aluminum installed under this contract shall, prior to installation, be free of corrosion.

c. All preparation, cleaning, and painting is to be conducted in strict compliance with the coating manufacturer’s specifications, especially pertaining to recoat and cure times, surface preparation, and environmental conditions of application. The coating manufacturer’s specifications are hereby incorporated by reference.
