i am stuck on the ship in splinter cell 1.cant find a route to next bomb. pleace help.

Here is a description of the bomb location on the Xbox 1 version of SCDA. It assumes that you got to the 'bomb' room via the crawlspace in the hall outside the crew quarters.

There are four bombs: two on the lower floor (one on each engine), one bomb just across from where you emerged from the ladder, and the last bomb is on the opposite side on the upper ledge.
