1. Scope

1.1 These detailed specifications contain requirements for NOAA Ship Henry B. Bigelow (R225) FY23 Dry Dock Repairs.

1.2 Scope and Intent of the Drydock or Dockside Ship Repair

Contract

1.2.1 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. The work items in the repair specification are identified well in advance of the performance period in order meet the contracting lead times.

Additional work items (emergent work) may arise during the period between the work package submittal, contract award, or even prior to the start of or during the contract performance period. 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 drydock or dockside 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.

a. Provide dry docking and routine dry dock work in accordance with Reference (a) and the following:

1. Dry dock the ship within 72-hours of ship’s arrival at the contractor’s facility.

2. Provide a tug(s) to assist in bringing the ship from the pier into the dry dock and to remove the ship from the dry dock to the pier. The tug(s) shall be of sufficient size to easily control the ship to/from the dry dock.

3. Use Reference (b) blocking position 1. Keel block heights shall not be lower than the heights shown on reference (b) to allow for access to transducers and centerboard. Use References (c) through (f) as guides. The blocking must be done as shown on Reference (b) with the aft keel blocks lower than the forward keel blocks. This allows the decks to drain when the ship is on the blocks. Having all the keel blocks being the same height will not be accepted.

4. After positioning and before hauling the ship, conduct a diver’s inspection of underwater keel block positions relative to hull mounted transducers and associated fairings to verify that keel blocks will not come in contact with these fixtures.

5. Ensure that all transducers (hull mounted and centerboard mounted), the 3 temperature probes on starboard side of the ship near frame 38 and the anti-foulant reference cells and anodes, located between frames 24-25 and 81-82 port/starboard sides (4 total) are covered in accordance with Reference (a), paragraph 3.11.6, prior to cleaning the ship’s hull via high pressure spray. Use Reference (g) as a guide for the locations of all the hull mounted and centerboard mounted transducers. DO NOT SPRAY ANY TRANDUCER FACES OR WINDOWS WITH

HIGH PRESSURE SPRAY.

6. While the ship is in drydock, clean each transducer, including centerboard transducers, face or window from the hull bottom using a normal, mild, synthetic soap, water and a soft bristle brush. Only under extreme conditions use a piece of dull wood or very fine grade sand paper (by hand).

a) Do not use strong solvents,

b) Do not attempt to scrape with sheets of metal, screwdrivers or other metallic tools,

c) Do not use high pressure water to clean the transducers or windows.

7. Carefully inspect each transducer, transducer window, mounting hardware and seals for evidence of cracks, scrapes, blistering, corrosion or other anomalies that would indicate an unsound unit. Notify the COR immediately should any of these conditions are found.

8. Photograph and submit a report to the COR on each transducer and window cleaned. Photos should provide enough detail to clearly see the details of each transducer or window surface. Report should include transducer name, location, and condition remarks.

9. All transducers are installed through to the hull in the Transducer room (4-23-0) located between frames 23 and 29, reference 2.1.3. The transducers and types are arranged as outlined in reference (b) and listed in table 3.2.1. All acoustic windows are ¾ inch Plexiglas.

c. Measure and record stern tube bearing wear down readings, specifically the shaft-to Thordon stern tube bearing clearance in accordance with reference (i).

d. Inspect rudder sections to the extent possible without removing rudder welded access plates in accordance with reference (j). Remove bolted covers or obstructions, measure Neck Bearing, Rudder Hinge, Link System slide bolt to slide bushing clearance, completing the BEARING CLEARANCES table in reference (j). Perform an inspection of the rudder with COR, providing for a man-lift or scaffolding to reach all rudder areas. Provide results on a condition report. Notify ABS surveyor of availability for inspection.

e. In addition to feeler gage measurements of bearing/shaft/pin clearances taken above, perform a test of the rudder and the rudder flap clearances by jacking the rudder forward, aft, port and starboard to determine amount of travel at a convenient location to attach dial indicator measuring travel of the rudder with respect to the hull. Measure and record travel and dial indicator location(s) on a condition report.

f. Remove rudder and rudder flap drain plugs and inspect for water leakage into the rudder and flap. Renew and reinstall plugs upon receipt of condition report response.

g. Inspect existing hull mounted zincs for wastage.

These are nominal 23 pound bolted strap type measuring 1-1/4 inch x 6 inch x 12 inch. Check all bolts for tightness.

Reinstall void drain plugs using ABS approved thread anti-seize sealant on all plugs:

1. Skeg drain plug frame 87-88 starboard,

2. Aft stern tube structure,

3. Port & starboard bilge keels,

4. Rudder and rudder blade/flap.
