Method for installing a joint of conductor pipe to a conductor string

摘要

A method for installing a joint of conductor pipe to a conductor sting comprises raising the joint of conductor pipe from a non-vertical position with a lifting apparatus, wherein the lifting apparatus comprises: a first lifting ring connected to a lifting point through a first lifting line; a second lifting ring connected to the lifting point through a second lifting line; and an inner profile of the first and second lifting rings configured to receive and secure the joint conductor pipe in the horizontal position; engaging a segmented ring elevator about the raised non-vertical joint of conductor pipe; closing the segmented ring elevator about the raised non-vertical joint of conductor pipe; activating at least one powered slip of the segmented ring elevator to grip the joint of conductor pipe; raising the segmented ring elevator until the joint of conductor pipe is in a vertical position; positioning the joint of conductor pipe atop the conductor string; and connecting the joint of conductor pipe to the conductor string.
