Hi, I am looking for a title of a movie I watched on t.v. back in late 70's early 80's. There's a crew on I think abandoned oil rig or oil boat. Alien lifeform impregnates one of the crew and the alien starts hunting the rest of the crew after birth. This is all I remember of this movie. Does anyone know the title of an older movie that fits this description?

Inseminoid??

Perhaps The Intruder Within (http://www.imdb.com/title/tt0082565/usercomments)?

I think that is it.
