STATEMENT OF WORK

Justification: Cruise FY14 presented multiple sewage system problems that were complicated due the fact that individual areas of the ship could not be isolated which required a complete system shutdown to accomplish the work. Ship's aging saltwater piping requires continued maintenance and repair work. There is presently no means to isolate smaller zones of the living spaces rather than using existing valves that isolate an entire house.

In addition, one section of piping shall be removed from the overhead of an 02 port side fwd house state room living space and re-routed through the overhead of the adjacent passageway.

A hydrodynamic tank shall be installed on the end run of piping that serves the 03 deck forward house. This tank shall serve as a cushion to dynamic shock that salt water flushing pipework in the forward house presently endures.

The following areas are targeted as best places in the saltwater flushing pipework to install new “Ball Type” isolating valves.

01-151-02 ( passageway overhead ) - 1 1/4" 150# flanged brass ball valve

1-122-02 ( passageway overhead ) - 2" 150# flanged brass ball valve

1-137-01 (passageway overhead ) - 2" 150# flanged brass ball valve

1-121-01 ( stbd passageway overhead) - 1" brass ball valve brazed union connection

01-136-01 (cleaning gear locker overhead) - Crop out existing 1 1/4 gate type valve ....install new 1 1/4 brass ball valves brazed union connection

01-66-00 (Linen Locker overhead) - 2" 150# flanged brass ball valve

01-72-02 (passageway overhead ) - 2" 150# flanged brass ball valve

01-57-02 (passageway overhead ) - 2" 150# flanged brass ball valve

02-137 -01 (cleaing gear locker) - crop out existing 1 1/4" gate valves ....install new 1 1/4 brass ball valves brazed union connections.

02-110-01 (passageway) - 1 1/2 " ball valve brazed union connection

02-77-02 (passageway) - crop out existing gate valve and replace with new 1 1/2" brass ball valve brazed union connection.

03-119-02 ( passageway overhead ) - 1 1/2" brass ball valve brazed union connection

03-119-01 ( passageway overhead ) - 1- 1/4" brass ball valve brazed union connection

03-53-02 proposed space to install hydro tank on piping run

TBD – 4 Each Master shutoff valves (2 each in forward house and 2 each in after house) These are to supplement the individual area shutoff valves but are to be placed in the main supply lines feeding the forward and after houses
