Emissions 2008: Netherlands Continental Shelf, Port Areas and Ospar Region II
report
Since 2005 all merchant vessels over 300 Gross Tonnage are equipped with an Automatic Identification System (AIS). These systems transmit information about the ship, its voyage and its current position, speed and course. Static information, such as name, IMO number, ship type, size, destination and draft, is transmitted every six minutes. Dynamic information such as position, speed and course is transmitted every 2 to 10 seconds. Although meant for improving safety at sea, dynamic AIS information offers great opportunities to gain insight into the spatial use of sea and waterways. Local traffic intensities and densities can, for example, be calculated very precisely. By linking the AIS data with ship databases, additional characteristics about the ship can be used, allowing for calculations of emissions during movements. In 2008 a pilot study [1] has been performed, commissioned by the Ministry of Transport, Public Works and Water Management, DCMR and the Netherlands Environmental Assessment Agency, (PBL), in which the ship emissions were quantified for the port of Rotterdam area. The pilot study was successful. The knowledge about the level and spatial distribution of all emissions was improved, which is used for making policy with respect to emissions.
