WE HAVE TO EXECUTE A 48 INCH DIA CROSS COUNTRY ONSHORE PIPELINE 625 KM LONG APPROX.ACCORDINGLY WE HAVE TO SELECT/FINALISE THE SPECIFICATION OF THE FOLLOWING PIPELINE CONSTRUCTION & INSTALLATION EQUIPMENT :-
1) DOZERS FOR ROW CLEARING
2) GRADERS FOR ROW CLEARING
3) HYDRAULIC EXCAVATORS FOR TRENCHING
4) HYDRAULIC EXCAVATORS AS ROCK BREAKERS
5) EXCAVATORS AT THE LOCATION OF PADDING MATERIAL
EXCAVATION AND LOADING FOR TRANSPORTATION.
6) TIPPERS / TRACTOR TROLLEYS FOR SHIFTING PADDING MATERIAL
7) DOZERS FOR BACKFILLING
8) BACHOE FOR SPREADING THE TOP / BOTTOM PADDING MATERIAL
INTO THE TRENCH
9) SIDE BOOMS FOR BENDING (IE BENDING MACHINE )
10)SIDE BOOMS FOR WELDING (MAINLINE WELDING)
11)SIDE BOOMS IF ANY FOR TIE IN LOCATIONS
12)SIDE BOOMS FOR LOWERING
13)CRANE FOR STRINGING
14)BORING MACHINE FOR X-INGS
15)COMPRESSORS , PUMPS ETC FOR HYDROTESTING AND FINAL COMMISSIONING.
THE PIPELINE HAS A NORMAL TOP COVER OF 1M AND A NORMAL TRENCH SECTION WITH 45 DEGREE SIDE SLOPES.SIDE CLEARANCE FROM PIPE SIDEWALL IS AS PER NORMAL PRACTICE.TRENCH DIMENSIONS ARE
i) Bottom width of trench = 2.3 m
ii)Depth = 2.5 m (from NGL)
iii)Top width = 7.45 m
iv)Side slopes = 45 degrees inclination
v)Volume of trench per m length = 12.57 cubic metres.
vi)CSA of trench = 12.57 sqm
AVERAGE LENGTH OF SPREAD HAS BEEN ASUMED AS 70 KM.PLEASE SUGGEST AND PROVIDE ALL POSSIBLE INPUTS ; BASED ON PREVIOUS EXPERIENCE IN 48 INCH PIPELINE EXECUTION ; REGARDING THE SPECIFICATION AND NUMBER OF EQUIPMENT PER SPREAD OF 70 KM AVERAGE LENGTH.
ANY LOGICAL DEDUCTION ETC , FOR EXAMPLE , ABOUT THE LOAD CAPACITY OF SIDEBOOMS , COMPRESSOR CAPACITY FOR HYDROTESTING OR THE SELECTION OF RATING OF EARTHWORK EQUIPMENT ETC ; SHALL BE HIGHLY APPRECIATED AS A SUPPORTING DOCUMENT.ALL THESE DATAILS ARE REQUIRED BY US FOR FINALISING THE PURCHASE ORDERS FOR THESE EQUIPMENT ETC AND ANY ASSISTANCE IN THIS CONNECTION SHALL BE HIGHLY APPRECIATED.
