Long for an entry level job offshore on a rig

Im looking to get my foot in the door on an offshore rig but I'm clueless as to where I should start. I worked offshore on a ship in 2001 and 2006 between semesters at college but I'd really like to work on a rig.

I'm in the process of getting my TWIC card right now. Any help would be greatly appreciated.
hey man dont know bout offshore, but check out Kirby marine online. they interview in Baton Rouge send for piss test pass it send you to 2 weeks training in houston (paid and put up at scvhooll dorm) pass school and you will be on an intercoastal tug or seagoing fuel barge. GOOD LUCK!
