The Ocean Corporation

I live in Houston, TX and I want to enter the Oil & Gas industry for employment. To gain entry, I have been seriously contemplating attending a technical school. The Ocean Corporation - (school) touts their training as a way of gaining entry. Of course they make lots of positive claims about their graduates job opportunities, the salaries they command and the high industry demand for their graduates. Does anyone have any first hand experience with the Ocean Corporation School that they can share that might be helpful to in helping me to decide if should make this sizable investment?
