Yes in the late 80's and early 90's Kirby went on there first buying spree. They bought about 7 or 8 different inland companies, here are some of the names I can remember off the top of my head. Scott Chotin, TPT (Thomas petroleum transport), Western towing, Brent transportation, Ole man river transport. Sabine transport, and I can't remember the rest. They already owned Dixie Carriers and rolled all these inland companies into what is now Kirbly inland marine.
cmakin is correct they bought the Sabine tankers along with Sabine towing. All these ships were single hull steam power, and about at the end of there like span anyway. They also bought a small number of tankers from OMI. I think around 4 of them. They did not own them long maybe a couple years and sold them. I can't remember who they were sold to. I worked on one of the old OMI ships named "Ranger" it had Peilstik mains and Cat 398 generators and pump engines. I worked on it as a qmed in 90 or maybe 91. Been to long ago to remember the details. I saw the sister ship to the "Ranger" once, we passed it going in or out of the harbor, but I can't for the life of me remember the name of the thing. By the middle 90's Kirby had sold all the ships and was in the process of selling all there offshore red flag fleet, including the Dixie Carriers ATB's and red flag barges. Which was basically the Dixie Commander and the Dixie Avenger. Now the Sea Raven and Pacific Avenger. Ironic that Kirby wound up getting both boats back 15 years later.
