6.0 TASKS

Under this contract the contractor shall complete the following tasks and requirements:

Arrival

6.1 The contractor will dry-dock MV Ft Jefferson at its location with 24- hour security, using its dry-docking equipment to block the vessel on flat ground per its United States Navy/United States Coast Guard (USN/USCG) docking plans. After the vessel is out of the water, it will be placed on land for inspection, where the team will inspect underwater components; Pressure wash, and inspect the vessels bottom, waterline to keel; propeller inspection, remove rudders are shafts (if needed); prepare for painting, and repairs that might be required. Install ground cable from vessel to ground and provide power to vessel to shore power (460V or 240V, 200 amp, three phase A/C) for the hull being on land or docked. In addition, a gangway to access will be secured to the vessel, and fire hoses will be made available in case of emergency. The shipyard Quality Assurance (QA) team will ensure all compliance is within International Organization Standardization (ISO) Quality & Occupational Safety and Health Administration (OSHA) safety standards. Once all the necessary work is completed, the vessel is lowered back into the water using controlled re-launch processes and will be prepared for Sea-Trials.

6.2 After re-launching, the vessel will undergo sea trials to assess its performance and verify that all repairs and maintenance were successful and within compliance, tolerance, and compatibility. Shipyard QA team will sail the vessel for a minimum of 2 hours run in the open water with conditions at 80% load on all main engines to test all components on the vessel per the SoW and GIs.

Vessel Haul-Out

6.3 Safely haul out the 110' Swiftships supply vessel utilizing approved marine lifting equipment such as a travel lift, dry dock, or synchrolift rated for the vessel’s size, weight, and hull configuration.

6.3.1 Prior to haul-out, a pre-lift inspection must be conducted to assess lifting points, weight distribution, and tide or environmental considerations.

6.4 Once the vessel arrives, the contractor will prepare and implement the dry-docking plan per the ship’s construction drawings based on its existing techniques to determine deficiencies, test all mechanical systems: engines, and generators, audit engine hours records, take oil samples, and test electrical systems. In addition, a qualified quality assurance team and hull foreman will inspect the hull and superstructure and perform strength assessment, including plate thickness measurement and load testing of lifting and mooring points. Furthermore, the assigned PM will prepare a complete assessment report, perform an audit against the scope-of-work definition, and document every task to provide an Integrated Master Schedule (IMS) accompanied by a record of photos of observed deficiencies to be relayed to the Contracting Officer (CO)

6.5 Once the vessel is out of the water, it shall be pressure-washed to remove marine growth and debris from the underwater hull. Blocking and cribbing must be performed by qualified personnel to ensure the vessel is securely and evenly supported, with special attention given to structural integrity and load-bearing locations. The vessel shall be chocked and stabilized in a manner that allows safe access to propulsion shafts, rudders, struts, and associated hull penetrations.

6.6 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.

6.7 All cribbing materials must be marine-grade, non-damaging to the hull, and inspected prior to use. Adequate clearance must be provided beneath the shaft line and seals to permit safe removal and reinstallation procedures.

6.8 Sea chests and all other cooling system intake components: Inspect all sea chests, sea beam arrays, tunnels, hull openings, and grates for general appearance, loose, damaged, or missing grates, loose or missing fasteners, condition of sea strainers and lockwire on bolts, marine growth on grating slots, and any obstructions in the openings that might prevent proper suction and discharge of water.

Initial Shaft and Seal Area Inspection

6.9 Inspection: Conduct a preliminary inspection of the shafting system, stern tubes, and dripless seals for visible wear, corrosion, leaks, or misalignment. Document findings before proceeding with removal.

6.10 Shaft Removal: Disconnect shaft couplings, propellers, and any necessary hardware.

Carefully remove propulsion shafts, ensuring no damage to components or hull penetrations during extraction.

6.11 Detailed Shaft Inspection: Conduct a thorough inspection of each shaft for straightness, wear, corrosion, scoring, or other defects. Perform runout measurements and document results. If required, send shafts for machining or reconditioning.

6.12 Inspection and Service of Johnson Dripless Shaft Seals: Disassemble Johnson dripless shaft seals. Inspect bellows, bearing surfaces, O-rings, and face seals for wear or damage. Clean components and replace any defective parts per manufacturer’s guidance. Reassemble and pressure test seals.

6.13 The Contractor shall perform strain gage alignment inspections on the propulsion shafting before drydocking, in drydock before commencement of hot work and/or structural modifications, in drydock after completion of hot work and/or structural modifications, and after vessel refloating.

6.14 Shaft Reinstallation and Alignment: Once reinstalled, perform dockside shaft rotation and seal inspection. Confirm proper function with no leaks or abnormal vibrations.

Record results and obtain sign-off from vessel representative.

Remove and Reapply Antifoulant Paint

6.15 The substrate must be clean, dry, and in sound condition. Remove all oil, dust, grease, dirt, loose rust, weld slag, and other foreign matter to ensure adequate adhesion.

Conduct a high-pressure wash (minimum 5000 PSI) over the entire area to remove any chlorides. The minimum surface preparation for immersion and atmospheric conditions is SSPC-SP7 'Sweep Blast Cleaning' with a 2.0 mil (50 micron) profile. Any corroded or damaged areas must be prepared to SSPC-SP6 'Commercial Blast Cleaning' standard.

6.16 Remove all antifoulant paint from the underwater hull up to white boot stripe at the waterline (WL) using approved mechanical or abrasive methods, in accordance with environmental regulations.
