Sir a question regarding ror.. As we know alteration of course is best way to avoid close quarter situation & other one is to reduction of speed & in further take all her way off .. But sir when ship is in open waters the engines are not in maneuvering conditions like we have before approaching port or departure & etc.. so we have manual controls of engine so we can use teligraph from bridge but in open waters when we don't have manual control over teligraph or engine because engines are not ready for maneuvering & to get that engineers need some time to do that so after that we can control quick speed alterations using teligraph.. but if we are in a situation that we have to reduce engine speed to avoid any danger to navigation may be to avoid close quarter situation but engine is not ready for maneuvering so how we can alter speed ?

Sir, the easiest way to reduce speed will be to do rudder cycling. Just keep doing hard port to hard stbd continuosly. Your ships speed will reduce drastically.

@@prasobhsugadhan ok.. but sir if we do this to reducing speed for avoiding close quarter situation the other vessel will be in doubt, no sir?!

Ofcourse sir. That's going to be an issue, but its manageable. Also, do not let your ship swing too much to cause confusion. You will have to keep going port-stbd without large heading change. This is an emergency manoeuvre, if all options fail. Also, load on your engine will be extremely high. If you have any other way, try altering rather than rudder cycling. Please remember, this is not an authorised manoeuvre. I just told you this only since you asked the specific query. In all situations, altering your course is the best way rather than speed reduction. Also, remember sir, the moment Close Quarter situation arises, there is no more stand on and give way vessel. At that point, both vessels are give way. Hence, altering a few degrees a bit early will definitely solve the issue. I guess I'm confusing you with my reply. Kindly repeat any thing you need to get a better explanation with. Thank you.

@@prasobhsugadhan ok sir 👍👍.. But if we look for proper way to alteration of speed for avoiding danger situation, ask engine room for maneuvering & may be after 20 min we are in control on teligraph for reducing speed is the only way ? Or is there any other way to avoid this 20min of delay ? & In open sea can we control teligraph (say like if it is in full ahead & we get teligraph in slow ahead )without engine in maneuvering condition ?

Negative sir. They will have to reduce the RPM slowly to maneuvering RPM. Else, there is an option of directly reducing it in an emergency, but most probably the machinery will get damaged. I have worked on CPP ships, where there is no issue of reducing speed from sea speed, since you only change the propeller blade angle, as the engine is always rotating at constant speed. That is not normally found on bigger ship's, and hence the delay in reducing speed is a pressing issue for us deck officers.
