Manewr awaryjnego zatrzymania statku na torze wodnym

The paper deals with the problem of emergency stopping of a large vessel in a fairway, which has been blocked by another big ship. It is assumed that the proceeding vessel must be stopped, or at least its speed must be reduced to such extent that an effect of a collision with an obstructing ship will not be destructive – the stopping vessel, however, must not leave the fairway, as consequences of this may be very serious. There are considered two variants of emergency stopping manoeuvre: to reverse immediately engine to full astern or begin the manoeuvre by putting rudder hard-a-port or hard-to--starboard. Some indispensable corrective procedures while carrying on the emergency manouvre are also taken into account. In the last paragraph accomplishment of the manoeuvre is evaluated and some inferences are given.
