The introduction of Emission Control Areas (ECAs) in August 2012 created zones around Europe and North America that are now more expensive to transit. Eventually these areas of low sulphur emission are likely to be extended to most shorelines in the world.

These are not 'no-go' areas since eventually all ports in the world will lie inside them. But it does mean that another cost factor must be taken into account when planning voyages. Optimum routing already takes into account piracy convoys and risk areas as well as weather conditions.

Emission Control Areas require a precise costing of route alternatives which must take into account all elements of cost in order to see the comparative cost. This means that a route costing that did not include hire for example would be erroneous. Such calculations can not be left to the vessel which in any case may not have the necessary data. Optimum routing advice from a knowledgeable consultancy has probably never been more important.

We have therefore developed a calculation service that can properly compare two routes using data input by the user as well as data supplied by Marincom. In addition you can use this calculator yourself by simply sending us a request for an Excel copy.

The route comparison must of course be made before any routing advisories are given to the vessel.

Where no routing preference has been given by the client Marincom's policy is to use cost estimates when formulating route recommendations. For the purpose of finding the comparative cost we have found this procedure to be acceptably accurate.
