3. REQUIREMENTS

3.1 General.

3.1.1 CIR.

None.

3.1.2 Tech Rep.

Not applicable.

3.1.3 Protective measures - general. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces in the vicinity of the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness.

· Before removing Starboard propeller or propeller nut, fit a shore from the floor of the dock to one propeller blade near the root, to prevent shock transmission to reduction gear, as necessary.

· Protect propeller blade edges and blade roots with suitable covers, at all times until reinstallation, to prevent damage.

3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences). Known interferences include, but are not limited to the below-listed:

· Starboard Rudder

3.2 Work to be accomplished. The Contractor shall accomplish the below specified tasks for Starboard propeller, using Coast Guard Drawing 75-WAGL 4400-3 as guidance: as guidance.

3.2.1 Rudder removal and reinstallation. Remove the Starboard rudder.

3.2.1.1 The Starboard propeller cannot be removed without first removing the Starboard steering rudder blade.

3.2.1.2 Using Coast Guard Drawing 65 WD 2200-3, remove rudder blade. Blade is connected to rudder stock with fitted bolts, carefully identify/mark each bolt to its hole, to facilitate later reinstallation.

NOTE

If the contract work package includes work item, “Rudder and Rudder Stock, Remove and Inspect” coordinate this item’s rudder work with that item. In the event “Rudder and Rudder Stock, Remove and Inspect” is being performed include all rudder cost (bid) only in that item.

3.2.1.3 Upon completion of propeller work, reinstall the Starboard rudder blade, replacing bolts in same hole they were removed from and completing rudder installation in accordance with Coast Guard Drawing 65 WD 2200-3.

3.2.2 Propeller Removal. Remove the Starboard propeller. The Contractor shall turn over the removed propeller to the Coast Guard PA as a MTI item.

NOTE

If it becomes necessary to apply heat to facilitate propeller removal, ensure that the hub temperature never exceeds 500 degrees Fahrenheit; in addition, ensure that gland, packing ring, fill and vent plugs are removed, and the adjacent shafting and canvas under the blade edge guards are protected from flame impingement.

3.2.3 Inspection.

3.2.3.1 Strut and structure-Starboard. Because the Starboard propeller was damaged by striking an object, visually inspect the strut for signs of damage. Visually inspect all nearby hull areas, Starboard propeller and rudders for obvious signs of damage, including bends, cuts, upset metal, scraped paint, etc. Submit a CFR.

3.2.3.2 In-place Shaft Runout Readings-Starboard. To ensure the shaft is not significantly bent (from propeller damage/impact) take runout readings in the vicinity of the shaft’s propeller tapered end. Affix a dial indicator to a permanent nearby structure and indicate perpendicularly onto shaft. Contractor may propose alternate techniques to obtain shaft runouts, to the Coast guard Inspector for approval. Rotate shaft and observe runouts. Submit a CFR.

3.2.4 Propeller hub fitting check. In the presence of the Coast Guard Inspector and with the key in place, carefully check the fit of the propeller hub bore to the shaft taper by applying Prussian blue to the shaft taper.

3.2.4.1 Uniform fit. Obtain a uniform fit of 60 percent contact over the taper, with a slightly heavier fit on the larger end. Do not heat the shaft taper to compensate for a poor fit.

3.2.4.2 Propeller fit. If the fit is less than 60 percent, hand grind/stone the propeller hub bore to achieve the required fit.

NOTE

Do not machine the shaft taper.

3.2.4.3 Location inscription. When 60 percent fit has been obtained, make a small inscription on the shaft to mark the propeller location. Use this mark as a reference in final assembly.

3.3 Propeller Installation.

3.3.1 Cleaning. For the final assembly, the propeller bore and shaft taper surfaces shall be clean and free of bluing, lubricants, dirt, foreign particles, or any other substance, which would hinder moving the propeller along the taper. Install the propeller with dry metal-to-metal contact to obtain the maximum frictional force for torque transmission. Renew the rubber O-rings and packing before reassembly, if applicable.

3.3.2 Assembly. With the propeller installed on the taper in the same position as when fitted, install the propeller nut and drive up the propeller until it is advanced forward about 1/16" beyond the inscribed mark as specified in 3.2.4.3 (Location inscription). Lock the nut in place with an appropriate locking device.

NOTE

It is prohibited to use grease, oil, or other substances on the taper to help drive the propeller.

3.3.3 Void filling. When applicable, the Contractor shall fill all internal voids in the propeller hub and cap with rust preventive compound conforming to MIL-PRF-16173, Class II, Grade 3. Renew all brass plugs.

3.3.4 Adhere to the following warnings:

· Do not heat the propeller hub, to compensate for a poor fit on the shaft taper.

· Do not machine the shaft taper to achieve the required fit.

3.3.4.1 Lock propeller nut in place with new stainless steel lock washer or monel cap screws.

4. NOTES

4.1 Propeller details. The propeller is made of nickel aluminum bronze. It has four blades, is 48”DIA, has 40” PITCH.

3.4 Cutter conditions. The Contractor shall use the Full Load Condition, listed below for purposes of performing Pre-Award calculations as described in Appendix A (Requirements for Calculations) of SFLC Std Spec 8634.

Displacement (LT FW): 125.98

VCG (FT ABL): 9.15

LCG (FT aft FP): 29.57 LCF (FT aft FP): 32.52 Trim (FT by bow): 0.17 MT1” (LT-FT/Inch): 15.51

Table 1 - Blocking

Awareness

3.5 Pre-award calculations. The Contractor shall provide to the KO a set of preaward calculations, as described in SFLC Std Spec 8634 Appendix A.

3.5.1 The Contractor shall provide vertical side/bilge block offsets for any side blocks placed in a location where vertical offsets are not already defined by the docking plan.

3.5.2 The Contractor shall submit an alternate blocking arrangement, as part of the pre-award calculation submission, to compensate for any changes from the docking plan.

NOTE

1. The USCG has established several approved alternate docking plans for each vessel-class, to facilitate complete access to the entire U/W body structure, for periodic comprehensive inspection and/or 100% preservation. This inspection and preservation pattern and periodicity is a configuration management concern that is a vital requirement of the contract. Intention to deviate from these plans (fewer blocks, block spacing, additional blocks, etc) shall be identified on pre-award calculations (Paragraph 3.5.2); an alternate docking plan and mitigation strategy shall be provided to maintain preservation and inspection configuration.

2. Pre-award calculations may be deemed unsatisfactory - and may adversely affect contract award if they are submitted with the following detrimental factors:

a. No methods have been proposed that meet the requirements for the specified docking plan.

b. Proposed block shifting or fleeting risk-mitigating plan may result in delays in period of performance.

c. Proposed alternate docking plan violates USCG configuration management policies."

NOTE

The Coast Guard Underwater Hull Inspection Board (UWHIB) will recommend the extent of underwater body coating system preservation required based on the conditions found during the underwater hull survey.

3.6 Unplanned availability: Underwater body cleaning-removal of marine growth. Within four hours after the vessel has been docked, the Contractor shall start cleaning the entire underwater hull from the upper edge of the boot top down, including sea chest gratings, sea chest interiors, fairwaters, rope guards, rudder, shaft strut, z-drive, thruster tunnel, and zinc anodes, as applicable. The Contractor shall remove all marine growth, fouling, salt, and dirt from the underwater hull by High Pressure Fresh Water Wash, using a minimum pressure at the nozzle of 3,500 psi and maximum pressure of 7,000 psi. Complete the hull cleaning before marine growth hardens. Removal of gratings is not required. Do not use chemical additives in the freshwater wash. Take extreme care to avoid damaging or removing existing intact underwater body coating. Conduct the work in this paragraph in lieu of the work described in SFLC Std Spec 8634 paragraphs 3.4.4.1 and 3.4.4.2.
