3.1.6 Water used in preparation and washing procedures. The Contractor shall ensure that water used in all surface preparation tasks, including pre-surface preparation wash and water jetting, is of sufficient purity and quality that it does not prevent the surface being cleaned from achieving the required degree of surface cleanliness or non-visible contamination criteria.

Achieving greater productivity.

Achieving the required surface profile.

NOTES

1. Existing coating system on the U/W body surfaces may have a nominal thickness in excess of that which was originally installed, because of “patch-coats” applied during past drydock availabilities.

3.5 AF system protective measures. The Contractor shall employ coating system manufacturer’s recommendations to prevent AF coating damage if immersion time requirements are not met.

4. NOTES

4.1 Definitions.

4.1.1 U/W Body.

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

31 (Rev-0) 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 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.

3.6.1 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.

32 (Rev-0)

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 pressure of 7,000 psi. Complete the hull cleaning before marine growth hardens. Removal of gratings is not required.

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 be aware that fuel offloading is not mandatory to drydock the vessel.

3.8 Fleeting. At the Arrival Conference, the Contractor shall submit a second set of Drydocking calculations in accordance with SFLC Std Spec 8634, Appendix A for the alternate blocking position from that indicated in paragraph 3.4.1 Blocking position. Ensure the plans include any risk mitigating efforts necessary associated with other U/W body work items to ensure availability completion is not delayed.

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.
