Granted it has been 11 years since I graduated from Texas A&M - College Station with a BS-OE, but when I was looking at schools I found that even though many schools have an OE program, they often concentrate on different areas. Besides researching the quality of the degree program, try to find out what type of OE program they lean towards. I have seen OE's working on everything from subsea equipment, offshore structures, ROV/AUV, diving, coastal, dredging, etc. It sounds like you have a general idea of what you want to do if you are already looking into and OE degree, so make sure the school you pick is heavy on teaching what you want to do when you graduate.
Texas A&M does have a great OE program. If you are looking more for vessel systems design, then look at the Marine Engineering degree at Texas A&M-Galveston.
