1. SUCTION CHAMBER DEWATERING SUCTION CHAMBER DEWATERING THERE MAY BE UP TO 3 FEET WATER IN THE SUCTION CHAMBER. THE CONTRACTOR SHALL DEWATER AS NECESSARY TO INSTALL THE SUCTION BELL COFFER DAM. IF THE WATER IN THE CHAMBER HAS NOT COMINGLED WITH CONSTRUCTION OR INDUSTRIAL ACTIVITIES, IT CAN BE PUMPED TOPSIDE AND DISCHARGED TO THE RIVER THROUGH OUTFALL 92 WITH APPROVAL FROM C106.31. CONTACT C106.31 AT LEAST 30 DAYS PRIOR TO THE NEEDED DISCHARGE DATE TO ALLOW ENOUGH TIME FOR DISCHARGE COORDINATION AND NOTIFICATION TO REGULATORY AGENCIES. IF THE WATER IN THE CHAMBER HAS COMINGLED WITH CONSTRUCTION OR INDUSTRIAL ACTIVITIES, IT MUST BE COLLECTED AND DISPOSED OF AND IS NOT AUTHORIZED FOR DISCHARGE TO THE STORM DRAIN SYSTEM OR RIVER.

RDRY DOCK 8 MAIN DEWATERING PUMP SUCTION BELL MATERIALS EVALUATION SCOPE OF WORK: THE PURPOSE OF THE EVALUATION WILL BE TO DETERMINE THE REMAINING USEFUL LIFE OF THE EXISTING SUCTION BELL. THE EXISTING SUCTION BELL WAS INSTALL IN THE EARLY 1940'S (1942). THE SUCTION BELL IS PART OF THE DOCK DEWATERING PUMP INTAKE PIPING AND ARE EXPOSED TO PERIODIC SUBMERSION DURING DOCKING EVOLUTIONS. THE SUBMERGENCE IS OF RIVER WATER, WHICH IS CONSIDER TO BE BRACKISH SEA WATER OR SALT WATER. DOCKING EVOLUTION MAY BE UP TO A WEEK AND UP TO SEVERAL TIMES A YEAR. THE SUCTION BELL EVALUATION MUST INCLUDE PROFESSIONAL METALLURGICAL ANALYSIS AND SUBSEQUENT REPORT, TO INCLUDE THE FOLLOWING TESTS: 1. VISUAL INSPECTION VISUAL INSPECTION 2. ULTRASONIC TESTING (UT) ULTRASONIC TESTING (UT) 3. MICROSCOPIC IMAGING (SEM) MICROSCOPIC IMAGING (SEM) 4. MACROSCOPIC IMAGING MACROSCOPIC IMAGING 5. MOLECULAR SPECTROSCOPY TO INCLUDE IDENTIFICATION OF ANY MOLECULAR SPECTROSCOPY TO INCLUDE IDENTIFICATION OF ANY FOREIGN MATTER NOT CONSISTENT WITH CAST IRON 6. REPORT MUST INCLUDE SUMMARY OF TESTING CONDUCTED, REPORT MUST INCLUDE SUMMARY OF TESTING CONDUCTED, TEST RESULTS, MATERIAL CLASSIFICATION INCLUDING STRUCTURAL PROPERTIES SUCH AS YIELD AND IMPACT AND ULTIMATE STRENGTHS, A LIST OF COMPARATIVE PROPERTIES TO VIRGIN CAST IRON, AND LIFE EXPECTANCY PROGNOSIS. THE CONTRACTOR MAY REMOVE A SAMPLE FROM THE MAIN DEWATERING PUMP 1 SUCTION BELL AS REQUIRED TO COMPLETE TESTING. THE SAMPLE MUST BE TAKEN FROM THE BOTTOM OF ONE VANE OF THE SUCTION BELL AS INDICATED ON M-202. THE SAMPLE SIZE MUST BE LIMITED TO 1”X 3”. SIZES BEYOND THIS MUST BE X 3”. SIZES BEYOND THIS MUST BE . SIZES BEYOND THIS MUST BE REVIEWED AND APPROVED BY NAVFAC PRIOR TO CUTTING. THE ORIGINAL THICKNESS OF BELL COMPONENTS IS APPROXIMATELY 1.5”. VERIFY WITH THE LAB THE SUFFICIENT . VERIFY WITH THE LAB THE SUFFICIENT AMOUNT OF MATERIAL REQUIRED FOR TESTING AGAINST THE ABOVE CONSTRAINTS. SAMPLE MUST BE CUT IN A MANNER WHICH LEAVES A SMOOTH CONTOUR. SUBMIT SAMPLE TO NAVFAC FOR EXAMINATION PRIOR TO SENDING TO METALLURGICAL LAB FOR ANALYSIS. FOR ANALYSIS PURPOSES, THE SUCTION BELL SHOULD BE CONSIDERED TO BE IN A 100% RELATIVE HUMIDITY WHEN DOCK IS ON OPERATION AND THE SPACE DEALS WITH DRAIN WATER AT ALL TIMES. STATICALLY, THE BELL IS SUBJECTED TO FLUID PRESSURE WITH A ΔH=63.23FT. AS A MINIMUM, THE SUCTION BELL MUST BE ΔH=63.23FT. AS A MINIMUM, THE SUCTION BELL MUST BE H=63.23FT. AS A MINIMUM, THE SUCTION BELL MUST BE STABLE AND INTACT UNDER THIS PRESSURE. THE REPORT MUST INCLUDE ALL IMAGING AND TEST RESULTS TO BE REVIEWED BY NAVFAC ENGINEERS. ANY CALCULATIONS COMPLETED IN THE COURSE OF ANALYSIS PERTAINING TO STRUCTURAL INTEGRITY MUST BE INCLUDED IN THE REPORT. THE REPORT ANALYSIS MUST PROVIDE A DETAILED DESCRIPTION OF THE CURRENT CONDITION OF THE MATERIAL AND DESCRIBE THE RATE OF DETERIORATION OVER TIME WITH SUPPORTING GRAPHS AND/OR CALCULATIONS THAT SHOW DETERIORATION OF THE MATERIAL WITH A PRECISION OF 1X10^-6 METERS. THE CONCLUSION OF THE REPORT MUST ESTIMATE THE REMAINING USEFUL LIFE.
