... and m1ddle s1zed f1elds. Subsea Systems A few years ago many offshore operators bel1eved that subsea development would be the most l1kely method to be used for the development of deep-water reserves. Th.s.s ,nd,cated by the fact that many of the very f1rst subsea complet10ns were des1gned for...
