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

14 (Rev-0)

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 not mandatory to drydock the vessel except when specifically required below.
