PY-1 Gas field is the southernmost of the four sedimentary basins located along the eastern margin of India. It is bounded in the south by the Sri-Lanka basement massif and in the north and west by the Indian Craton.

The job consisted in delivery of Pile top rig PBA 810 and a complete drill-string to install the PY-1 Sun Wellhead Jacket.

The PBA 810 with 180 meter drill string with a 1240 mm diameter Bottom Hole Assembly was on board as a contingency for the pile driving, for soil plug removal.
