This has been an interesting read. I'm a Civil Engineer, and licensed, working in the engineering field for 24+ years (and a diver for >28 years)........ I've dove for work related items a quantity of times that can be counted on one hand......
Now, if you can find a company specifically doing diving (Oceaneering was one I came across years back), you might get the two to mix well. Keep in mind, you are looking at a significant amount of time in school for an engineering degree (5 years for a BS, and a Master's Degree is now highly desired), Commercial Diving School, and then 3-5 years minimum of significantly progressive involvement to obtain a Professional Engineering License.
You will serve an "apprenticeship" in either situation for quite some time as you start at the bottom of the list......
