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). Known interferences include, but are not limited to the following:

Anchor assembly

Load conditions

U/W body appendages

3.2 Key personnel. The Contractor shall determine key personnel and require their presence during all drydocking phases as required by SFLC Standard Spec 8634. Submit list of key personnel to the COR.

3.3 Docking. The Contractor shall perform all drydocking procedures in accordance with SFLC Std Spec

8634, using a cradle built as shown on Coast Guard Drawings 110 WPB 085-002 or 110 WPB 085-010, as applicable (see “NOTES” under paragraph 3.4.2).

NOTE:

When a cradle is not available and only on a case-by-case basis, the

Contractor may submit a blocking proposal to the KO for approval for docking via a floating, graving, or vertical lift dry dock. Blocking shall be in accordance with Coast Guard Drawing 110 WPB 085-010.

Due to the 110 hull sensitivity to deformation, docking via cradle is the preferred method when a cradle is available. A cradle shall be used when using a travel lift or crane lift.

This note supersedes the mandatory cradle use note under paragraph C2.4 of

SFLC Standard Spec 8634, 2014. All other requirements of SFLC Std Spec

8634 shall apply. Blocking calculations shall be provided for the blocking proposal.

3.4 Cutter conditions. The Contractor shall use the Full Load Condition values listed below all in inches, for purposes of performing Pre-Award calculations as described in Appendix A (Requirements for

Calculations) of SFLC Std Spec 8634.

Displacement (LT): 169.65.

VCG (FT ABL): 8.93.

LCG (FT aft of amidships): 5.15.

Length Over All (FT): 110.0.

Length of supported keel (FT): NA

3.4.1 Blocking. The Contractor shall facilitate docking the vessel in designated block position by arranging keel and side blocks and ensuring minimum block heights as shown on the vessel's docking plan.

NOTES:

Many of the cradles used to dock the 110's were built to the early drawing

085-002. The newer cradles have been built to 085-010. The drawings show minor variations in dimensions. It should be noted that while the Standard

Spec calls for the cradle to be built just to 085-010, a cradle built to 085-002 is acceptable.

There is a discrepancy between the SFLC STD Spec 8634 and the CG

Drawing 110WPB-085-002 concerning drydock block thickness. SFLC STD

Spec 8634 requires a minimum thickness of 2 inches, while the drawing has the block thickness at 1.5 inches. The Contractor shall disregard the 1.5-inch thickness shown on the drawing, and use the 2-inch thickness as specified in

SFLC STD Spec 8634.

CG Drawing 110 WPB 085-002, Sheet 3, Section F-F (Position 2, only), the height above blocking line at 2’-0” from center line should be 3’ and 3-3/32”.

3.4.2 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 3.4.

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 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 Submit an alternate blocking arrangement, as part of the pre-award calculation submission, to compensate for any changes from the docking plan.

3.5.2.1 If the alternate blocking arrangement interferes with U/W hull plate inspection or 100% preservation of U/W body surfaces required under separate work items in this specification package, the

Contractor shall include a plan of how inspection/preservation will be accomplished. Plan shall include

15 (Rev-1) any modifications necessary to the prescribed docking plan including removing, shifting, repositioning blocks, or fleeting the vessel at no additional cost to the Government.

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) is to be identified on pre-award calculations (Paragraph 3.5.2); an alternate docking plan and mitigation strategy will 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 Planned availability, immediate work and routine inspections. The Contractor shall perform designated routine drydocking work, in accordance with SFLC Std Spec 8634, paragraph 3.5.4 (within twenty four hours after docking).

3.6.1 Upon the COR convening the Coast Guard Underwater Hull Inspection Board (UWHIB), the

Contractor shall facilitate and participate in the UWHIB inspections of the underwater hull. The

Contractor shall provide a designated hull repair supervisor to accompany the UWHIB and mark on the hull proposed repairs areas, as necessary.

NOTES

1. The COR will convene the UWHIB as soon as possible after the vessel has been dry-docked and the hull has been cleaned. No other work shall take place until the UWHIB completes their inspections.

2. The 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. The Contractor shall accomplish the work in this paragraph in lieu of the work described in SFLC Std Spec 8634 paragraphs

3.5.4.1 and 3.5.4.2. 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

16 (Rev-1) pressure of 7,000 psi. Complete the hull cleaning before marine growth hardens. Removal of gratings is not required.

- Provide option to clean hull in the water, and inspect for further cleaning after cutter is undocked. (Environmental concern)

WARNING

Do not use chemical additives in the freshwater wash. Take extreme care to avoid damaging or removing existing intact underwater body coating.

3.7 Fuel offloading. The Contractor shall remove and dispose of up to 9300 gallons of fuel from the vessel.

3.8 Fleeting. Not required.

3.9 Fluid removal and disposal. Refer to Table 1 – Tank Information, in the Notes Section, paragraph 4.2

Tanks.

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 110 WPB 085-010. Dispose of all fluids in accordance with Federal, State, and local regulations.

3.9.3 Dirty oil and oily water. The Contractor shall remove and dispose of up to 155 gallons of dirty oil and up to 155 gallons of oily water from the vessel.

3.9.4 Sewage and grey water. The Contractor shall remove and dispose of up to 550 gallons of sewage and up to 130 gallons of grey water from the vessel.

4. NOTES

4.1 Arrival conditions. The COR will advise the Contractor of the actual tank and draft readings when the vessel arrives, and will discuss with the Contractor any liquid loading changes necessary.

4.2 Tanks. The tanks identified in Table 1 below require fluid offload.
