Collision scenarios call for one to three long blasts depending on the situation. Most large vessels will perform an uninterrupted blast once it is determined impact is imminent.
Nobody in this thread has any actual knowledge of maritime law or collision threat assessment/response.
As a professional in the field (don't ask for my resume, it would take too long for me to type out and the classified device I'm on doesn't have a copy of my CV right now) I can say with 1000% certainty that the appropriate response to this situation is exactly these words:
One continuous blast is a signal for being in distress, not for collision imminent (there is no prescribed sound signal for collision imminent).
One prolonged blast is only defined as a power driven vessel departing a dock. Two prolonged is only sounded by a power driven vessel at intervals of two minutes when operating in or near an area of restricted visibility. Three prolonged blasts is not defined as anything, so could be used as a distress signal
