Finished only SE/IR in Belgium and what mentioned above ME is required.
It's not unheard of for people to get an offshore job with a SEIR, I know of people on this site who were hired by CHC with exactly that completed on the Longranger (BAC Denmark), but it is not helping your cause, when also with low hours, jockeying against other applicants on paper who have MEIR's (AS355/EC135). They would likely interview people with ME type ratings and MEIR's first unless you have something else enticing on your CV.
