3.1 General.

3.1.1 CIR.

None.

3.1.2 Tech Rep.

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).

3.1.5 Dive notification. The Contractor shall provide the Coast Guard Inspector 24 hours advance notice of when the diver inspection will occur. Before diving procedures are commenced, meet with the COR and the Coast Guard Inspector, to discuss diving safety requirements and the securing of cutter machinery, as applicable.

NOTE

Coast Guard preference is to schedule diving operations as near as possible to the end of the availability in order to minimize development of new growth prior to sea trials.

3.2 Pre-diving requirements.

3.2.1 The Contractor shall, in accordance with 29 CFR 1910.401-440, provide a certified diver and a tender team, as well as necessary support personnel and equipment, to accomplish the tasks specified herein.

WARNING

Mixed gas diving and live boating are not permitted.

3.2.2 The Contractor shall ensure that the diving team shall obtain clearance from the Officer-of-the-Deck (OOD) before beginning diving operations. Ensure the Coast Guard Inspector has capability for maintaining continuous two-way communication with diving personnel at all times, during the performance of the this work item.

3.3 Inspection requirements. Using the drawings listed in Section 2 as guidance, the Contractor shall perform the following inspections and fill out forms provided in Section 4. Submit CFR with results of inspections.

13 (Rev-1)

3.3.1 Conduct a pre-clean biofouling inspection. Fill out Form 4-1, including fouler rating for each component (see Table 1 for fouler rating descriptions).

NOTE:

When completing the fouler rating, ensure that all (100%) of the area of the component/surface being inspected has a fouler rating. For example, if only 50% of the rudder has growth at a FR-20 rating, then there should be another rating on the rudder that is FR-0 rating over 50% of the area. All ratings should equal 100% of the area/component being inspected.
