1.

For the purposes of monitoring other relevant information on a per-voyage basis (Article 9(1)), companies shall respect the following rules: the date and hour of departure and arrival shall be considered using Greenwich Mean Time (GMT). The time spent at sea shall be calculated based on port departure and arrival information and shall exclude anchoring; the distance travelled may be either the distance of the most direct route between the port of departure and the port of arrival or the real distance travelled. In the event of the use of the distance of the most direct route between the port of departure and the port of arrival, a conservative correction factor should be taken into account to ensure that the distance travelled is not significantly underestimated. The monitoring plan shall specify which distance calculation is used and, if necessary, the correction factor used. The distance travelled shall be expressed in nautical miles; transport work shall be determined by multiplying the distance travelled with the amount of cargo carried; for passenger ships, the number of passengers shall be used to express cargo carried. For all other categories of ships, the amount of cargo carried shall be expressed either as metric tonnes or as standard cubic metres of cargo, as appropriate; for ro-ro ships, cargo carried shall be defined as the number of cargo units (trucks, cars, etc.) or lane-metres multiplied by default values for their weight. Where cargo carried by ro-ro ships has been defined based on Annex B to the CEN standard EN 16258 (2012), covering ‘Methodology for calculation and declaration of energy consumption and GHG emissions of transport services (freight and passengers)’, that definition shall be deemed to comply with this Regulation. For the purposes of this Regulation, ‘ro-ro ship’ means a ship designed for the carriage of roll-on-roll-off cargo transportation units or with roll-on-roll-off cargo spaces; for container ships, cargo carried shall be defined as the total weight in metric tonnes of the cargo or, failing that, the amount of 20-foot equivalent units (TEU) multiplied by default values for their weight. Where cargo carried by a container ship is defined in accordance with applicable IMO Guidelines or instruments pursuant to the Convention for the Safety of Life at Sea (SOLAS Convention), that definition shall be deemed to comply with this Regulation. For the purposes of this Regulation, ‘container ship’ means a ship designed exclusively for the carriage of containers in holds and on deck; the determination of cargo carried for categories of ships other than passenger ships, ro-ro ships and container ships shall enable the taking into account, where applicable, of the weight and volume of cargo carried and the number of passengers carried. Those categories shall include, inter alia, tankers, bulk carriers, general cargo ships, refrigerated cargo ships, vehicle carriers and combination carriers.
