Drilling Rigs Built in U.S. Shipyards

Most recent update: June 25, 2015


The offshore drilling rig was invented in Texas and, until the early 1970s, almost all the world's rigs were built in U.S. yards.  All that has now changed: of the 377 rigs listed here, only 29 were built in a year beginning with a 2.  With regard to the accuracy and completeness of this table, it's a little difficult to track the inactive rigs: some may be cold-stacked, others may have been scrapped.  If anyone has any information that would help, please share it with me by sending it to timcolton@aol.com
