The article presents the origin of Emission Control Area (ECA) zones, a timetable for their enforcement, criteria of their implementation and the principles and rules of navigation in these areas. Plans and areas of the next ECA zones envisaged for the future are presented. Least fuel route programming was presented, together with a description of safety rules during the change-over procedure in operations concerning the main engine and other ship systems. An attempt to identify the problems that may be encountered when programming the routes with the use of on-board routing systems, like Bon Voyage of AWT, leading through the ECA zones, has been made. Examples of such problems, taken from a true voyage of a postpanamx container vessel on a transpacific voyage, have been presented. A generalized algorithm for programming the route leading through the ECA zone according to the least fuel criterion has been presented.

Application of Bon Voyage 7.0 (AWT) to programming of an ocean route of post-Panamax container vessel in transpacific voyage Seattle – Pusan 26.08.2015, 1600UTC – 05.09.2015, 2100UTC

The results of testing the Bon Voyage system for an ocean voyage are presented in this paper. The main assumptions of testing were: ETD – 26.08.2016 and ETA – 05.09.2016, as established by the owner. All the data have been obtained from an actual voyage of a post-Panamax shipping container through the North Pacific. Testing was repeated again after completion of the voyage (post-voyage analysis). The data indicate that improved results with respect to fuel consumption could have been achieved using a different moment of second stage testing. Possible problems at planning, programming, and optimizing of the route leading through the ECA (Emission Control Area) zones with the use of onboard routing systems are also presented.
