L'eau d'Issey is a marine projection monster. I strongly dislike marine notes personally, but if they work on you, they are indeed very intense and long lasting. Another monster in the style is Light blue (which I like even less than l'eau d'issey, but it delivers). More well behaved, there are things like New West and Cool water.
You could also check vetivers like Tom Ford Grey Vetiver. They are usually long lasting and intense, but as usual, you need to try on skin.
