Suction and Discharge Valve Repair and Renewal

· The two 8 inch Suction Butterfly Valves shall be rebuilt renewing all soft parts.

· The two 6 inch Discharge Stop Check Valves shall be rebuilt with new seats and discs or renewed. Current valves are Bronze 150 angle stop checks manufactured by Pima.

· For estimating purposes consider supplying new Butterfly valves and Stop Check valves versus removal and repair of same. Contractor should designate their preference with this quotation. If new valves are to be supplied rig and store the old valves to a place designated by the Chief Engineer

New Pump Installation

· Rig the new pumps from the midships stored location to the lower engine room. Ship’s cranes can be used but must be operated by ship’s personnel

· New pumps will require modification or replacement of the support base. Contractors should bid to renew the support base if they do not feel that they can reuse same to fit the foot print of the new pumps. Manufacturers specifications and instructions will be made available at the time of the ship walk or earlier if necessary. The new pumps can also be viewed aboard the vessel

· As a possible option, New pumps can be supported by plate “Saddles” bolted to pump suction and discharge flanges and bolted to existing 6” x 6” angle iron support structure which crosses fore and aft at pump flanges. Saddles can be fashioned in an inverted triangular shape so as to spread load of pump across more of support structure

· Target the new pumps discharge flanges to the existing 6 inch discharge elbows if at all possible . If new pump dimensions are not possible to align same, change the piping to fit up to the pump without putting same in any stress or misalignment

· Under all circumstances, the pump must be made up so that the connecting piping does not have to be forced into position. This line up must be proven to the Chief Engineer and MARAD surveyor before final welding or attachment.
