CIR. None. Tech Rep. Not Applicable. Protective measures. The Contractor must 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 must remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness. The Contractor must 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 At Contractor’s request, Ship’s force will secure and tag out the cathodic protection system, main engines, steering gear, generator set, A/C unit, fire pumps, and all other machinery which may cause a hazard while a diver is in the water. Pre-diving clearance. The Contractor must ensure that the diving team obtains clearance from the Officer-of-the-Deck 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 this work item. The Contractor must, 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. Hull inspection requirements - general. The Contractor must survey the entire U/W body of the vessel to inspect for abnormal conditions or situations, which may include, but not be limited to the below listed. Hull plating and appendage damages. Coating system defects or failures. Welding corrosion and erosion. Deformation in appendages. Zinc performance. Hull plating. The Contractor must inspect the exterior condition of the hull for presence of marine growth, deformation, and any evidence of major corrosion or electrolytic action. Inspect for deformation along the stem and keel areas, condition of butt-welded seams, doubler plates, lap seams, and any signs of damaged plating or unusual waviness in the plating. Coating system inspection. The Contractor must inspect the condition of the U/W body coating system, for signs of the following: Peeling. Blistering. Abrasion. Use the guidelines provided in Table I (Paint Deterioration Ratings (PDR) for Antifouling/Anticorrosion (AF/AC) Paint System) and Table 2 (Fouling Ratings (FR) In Order of Increasing Severity) to assist in proper documentation of the coating system degradation and fouling rate, respectively.
