Back in Houma, La., the completed topsides were loaded onto a barge. After a 10-hour trip through a canal, the barge arrived in the open water of the Gulf of Mexico. Another voyage of more than 20 hours brought the topsides to the TBells site, 135 miles southwest of New Orleans. There, huge twin cranes lifted the topsides from the barge and placed them in their final home atop the floating spar.
