All material, unless specifically identified as Government-furnished, shall be furnished by the contractor.

The Swell Compensator Compartments are located between Frames 74 and 76, Port and Starboard. Access to the compartments is gained through an access hatch (approximately 24” x 20”) located on the Inboard Bulkhead of the respective Aft Winch Room. The hatch is bolted and located approximately 6’ above the deck in the Winch Room.

NOTE – The Swell Compensator Compartments measures 6’ x 6’ x 14’.

CHECKPOINT – Coordinate with the crew and the Port Engineer and ensure the electrical systems and hydraulic systems are disconnected, secured, and tagged-out.

The contractor shall provide the services of a Marine Chemist to inspect the compartment and provide a certificate stating the compartment is safe for entry and hot work.

The space shall be made safe for entry and hot work in accordance with all applicable Federal, State, and Local laws and regulations.

The contractor shall also provide the services of a Competent Person to check the Compartment(s) daily prior to the start of the work.

NOTE – The dragarm layshaft motors are located near the access hatches. Extra care shall be taken to protect the motor from damage, foreign matter, contact with contractor’s equipment and material, and fluids. At no time shall the motor be used as a working or step platform. The contractor shall cover the motors with plastic sheeting while any work is being performed in the winch rooms and/or swell compensator compartments.

The contractor shall provide and maintain lighting and ventilation of the Swell Compensator Compartments and the Aft Winch Room. All ventilation shall exhaust to the outside and shall be routed through the escape hatch in the respective Winch Room.

The contractor shall have appropriate Firewatch in place during all burning, gouging, and welding operations.

All welding shall be in accordance with U.S. Coast Guard and American Bureau of Shipping requirements and shall be performed by ABS-approved welders. All welding shall be inspected and tested in the presence of the Port Engineer.

The contractor shall establish and maintain the watertight integrity for the 6” diameter spool piece bulkhead penetration at the completion of the work herein. All watertight penetrations shall be water hose tested for watertight integrity in the presence of the Port Engineer. All watertight penetrations shall be welded on both sides of the bulkhead.

A. Lead Paint/Asbestos Tape Removal

The exterior surfaces of the Aft Winch Room Inboard bulkheads where the 6” piping penetrates the bulkhead were originally coated with lead-based paint. The contractor shall remove all lead paint as necessary to perform and complete all work listed herein and include all costs herein. All lead removal to be in accordance with all Federal, State, and Local laws and regulations. Any steel affected by lead paint removal shall be painted to match the surrounding.

The contractor shall remove the perforated sheathing and insulation as necessary to remove the 6” diameter spool piece (approximately 2’ x 2’ area). The perforated sheathing is attached to the framing with screws and seams with double sided asbestos tape. Removal and disposal of the asbestos tape of the sheathing shall be in accordance with all Federal, State, and Local laws and regulations.

Replace all removed perforated sheathing and insulation with Government-Furnished Material.

B. Piping Replacement

The contractor shall provide all necessary labor, material, services, and equipment to perform, coordinate, test and complete the work listed herein.

The contractor shall furnish and install new steel piping, pipe fittings, flanges, tags, valves, gaskets, reducers, O-Rings, pipe supports, and all associated hardware in accordance with the Drawings and Specifications provided by reference. The contractor shall connect the pipe sections by welding or use flanges where applicable to match original construction

NOTE – The system operating pressure is 150 PSI.

All the sections of the Swell Compensator hydraulic piping are located inside the Swell Compensator Compartments. The 6” hydraulic line from the Swell Compensator tank to the first flange outboard of the Aft Winch Room Inboard Bulkhead shall not be replaced. All the piping to be renewed is shown in the following sketch.

Disconnect the existing hydraulic piping at the 6” diameter spool piece. The spool piece is seal welded all-around to the ring plate on Inboard side of the Aft Winch Room Bulkhead. Remove the ring plate to gain access to Outboard flange.

NOTE – The contractor shall estimate on furnishing and installing 6’ of 6” diameter Schedule 80 hydraulic piping per side.

NOTE – Prior to removing the 6” diameter spool piece, the contractor shall ensure lead paint and double-sided asbestos tape has been removed. See Section A of this Scope.

Start the removal process by disconnecting the 6” piping at the first flange before the cylinder ram, 3” line at the first flange and reducer below the Boat Deck Level, and at the neck flange.

NOTE – The contractor shall estimate on replacing 16’ of 3” diameter Schedule 40 hydraulic piping and 6’ of 1-1/2” diameter Schedule 80 hydraulic piping per side.

NOTE – Extra care shall be taken to protect the Cylinder Ram Housing. Install temporary blanks over flanges where pipe has been disconnected.

CHECKPOINT – Inform Port Engineer that pipe sections have been removed so that compartment can be inspected.

The contractor shall remove all piping including the two 3” Swing Check Valves (MF-M9-18, H- 20), and two 1-1/2” Globe Needle Valves (MF-M9-18, H-21) incorporated within the Swell Compensators and replace with new contractor-furnished valves. The new valves shall have either bronze or stainless steel bodies. Install new valves with contractor-furnished stainless-steel fasteners and new contractor-furnished gaskets.

NOTE – The contractor shall test individual pipe sections in the shop, as access into the compartment will allow.

Chemically clean and treat internal surfaces of all the pipe sections prior to reinstallation. Extra care shall be taken to protect the open pipe sections of the hydraulic system from any foreign material.

The contractor shall reinstall all new piping and valves to match the original. Once completed, the contractor shall flush the system as stated in Section C of this Scope.

Test newly installed pipe sections and valves during flushing and/or operational test. Correct any leaks at no additional cost to the Government.

Reinstall all removals and return to proper working order.

On all new piping and disturbed steel, apply one coat of Government-Furnished Rust Grip. All piping inside the compartment shall have a final topcoat of Government-Furnished Amercoat 385, Black.

The disturbed steel shall be primed with Government-Furnished Rust Grip and painted to match surrounding color.

The contractor shall fill the system with two 55-gal drums of Government-Furnished Shell EcoSafe S3 DU 100 hydraulic fluid to assure full circulation to all components. Connect the filtration pump suction to accumulator drain line. Connect the filtration pump discharge to oil fill line on the top of the accumulator. During the flush, operate the Swell Compensator up and down every 10 minutes. Flush the system for minimum of 4 hours using the 10-micron filtration unit.

NOTE - Care shall be taken during filing operation to vent the entire system to ensure the elimination of trapped air.

If the flushing fluid shows any sign of contamination, repeat the flush again until satisfactory.
