Scope of an Electrical Officer at Shore

Hey frnds, I, Joganand working as Electrical Officer/Electrician on a dredger for the past 2years, after my successful completion of my graduation in Electrical and Electronics Engineering. I would like to work mainly in core sector, but every where electronics,communication and instrumentation playing major role in leaving very less scope for electrical. (is what I feel). Kindly guide me, what subjects/courses knowing better can really help me out with latest growing technology.
