CONDUCTOR CASING INSTALLATION BY ANCHOR HANDLING/TUG/SUPPLY VESSEL |
摘要 |
An anchor handling/tug/supply (AHTS) vessel is employed to engage conductor casings with the seafloor. The conductor casings initially penetrate the seafloor to a first depth under their own weight. The conductor casings may optimally be further engaged with the seafloor to a second depth by the application of suction to the interiors thereof or by the use of a drop hammer. The conductor casings are driven to grade by a hydraulic pile driving hammer deployed from the deck of the AHTS vessel the previously deployed conductor casings to grade before being recovered to the deck of the AHTS vessel.
