Design of PH/PJ Wellhead platforms at Panna field with water depth of 40.6m & 52.3m and new Wellhead Platform STD at South Tapti field at a water depth of 22.8m |
|
|
| |
Design of two Wellhead Platforms N9/N10 consisting of each 9 30”/20” well slots |
|
|
| |
Design of jacket substructures of N9/N10 with skirt piles stands at a water depth of 70.5 & 66.4m respectively with a topside lift weight of each platform up to 812 MT |
|
|
| |
Design of PS-2/PS-3 Wellhead Paltforms at a water depth of 36 & 20m respectively |
|

Pile Instrumentation during installation |
|
|
| |
Instrumented where hard driving/pile refusal was anticipated. The major objectives were |
|
| |
|
Monitor Hammer performance (energy transfer) |
|
| |
|
Mobilized capacity by re-strike after delay |
|
| |
|
Pile Integrity assessment |
|
|
| |
Four bridges has been designed & analysed with 3 bridges for PS2 and 1bridge for PS3 field. The span of the bridges being 117.6m, 42.307m, 35.574m and 62.308m for bridge between 2Q-2J, 2G-2J, 2C-2J & 3Q-3G platforms respectively |
