Not applicable.

3.1.3 Protective measures. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces near 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.

3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences).

3.2 Key personnel. The Contractor shall determine key personnel and require their presence during all drydocking phases.

3.3 Docking requirements. The Contractor shall perform drydock and undock in accordance with SFLC Std Spec 8634, using Coast Guard Drawings 87 WPB 085-011, 87 WPB 085-012, and 87 WPB 085-013 for guidance.

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): 90.39.

· VCG (FT ABL): 7.62.

· LCG (FT aft of Frame Zero): 51.96.

· Length (Molded) (FT): 86.92.

· Length of supported keel (FT): 61.05 (Position 1)

· Length of supported keel (FT): 50.88 (Position 2)

3.4.1 Cable, sling, or strap tension calculation. If the Contractor plans to use a vertical lift, crane, or travel/mobile lift to haul out the vessel, the Contractor shall submit the cable, sling, or strap tension calculation specified in Table A1 and paragraph A2.7.2.7 of SFLC Std Spec 8634 with the Pre-Award calculations, using the loading condition specified in paragraph 3.2.1.

3.4.2 Blocking. The Contractor shall facilitate docking the vessel in block position 2 by arranging keel and side blocks and ensuring minimum block heights as shown on the vessel's docking plan. Contractor's use of a cradle, built to Coast Guard Drawing 87 WPB 085-12, shall require the fitting of keel blocks with soft wood wedges, based on the docking positions noted in Coast Guard Drawing 87 WPB 085-013, after lifting.

Table 1 - Blocking

Awareness

3.5 Pre-award calculations. The Contractor shall provide to the KO a set of pre‑award 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."

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.

3.7 Fuel offloading. The Contractor shall be aware that fuel offloading is mandatory to drydock the vessel.

3.7.1 Fuel offloading exception. The Contractor shall remove and dispose of up to 3000 gallons of fuel from the vessel.

3.8 Fleeting. Not required.

3.9.1 The Contractor shall drydrock the cutter with all tanks empty.

3.9.2 The Contractor shall empty all tanks in order to fulfill the drydock requirements, shown on Coast Guard Drawing 87 WPB 085-013. Dispose of all fluids in accordance with Federal, State, and local regulations.

3.9.2.1 Dirty oil and oily water. The Contractor shall remove and dispose of up to 85 gallons of dirty oil and up to 85 gallons of oily water from the vessel.

3.9.2.2 Sewage and grey water. The Contractor shall remove and dispose of up to 363 gallons of sewage and up to 55 gallons of grey water from the vessel.

3.10 Inaccessible voids.

3.10.1 Inaccessible void inspections. In the presence of the Coast Guard Inspector, the contractor shall accomplish the following tasks for all non-accessible voids and submit a CIR:

3.10.1.1 Remove and dispose of the existing drain plugs.

3.10.1.2 Submit a CIR noting any liquids draining from any of the voids – indicating the presence of a leak.

3.10.1.3 Dispose of any drained liquids in accordance with all federal, state, and local laws and regulations.

CAUTION

Some liquids that are drained may be classified as hazardous materials or hazardous waste depending on state and local regulations. The vessel environmental coordinator may assist with determination of waste category.

3.10.2 Plug renewal. Upon completion of all work on appendages, the Contractor shall accomplish the following task:

3.10.2.1 Chase the hull inserts threads of all plugs.

3.10.2.2 Install new stainless steel, Type 316, or Monel drain plugs, in place of original plugs.

WARNING

Do not machine the shaft taper.

3.2.3.3 Hand clean the new propeller hub bores and shaft tapers to remove all foreign particles for a clean metal-to-metal fit. Install the new propellers onto the propulsion shafts. After the propellers are installed on the tapers, install the propeller nuts. Using the propeller nuts, drive the propellers onto the tapers.

3.2.3.4 Lock each propeller nut in place with new Contractor-furnished, stainless steel 3/8” x 6” cotter pins.

3.2.3.5 Reinstall the fairing plates as shown on Coast Guard Drawing 87 WPB 243-001.
