AIS ANALYSIS OF IDLE TIME IN DIFFERENT SCANDINAVIAN OIL REFINERY PORT AREA
Conference contribution, 2018
This study has been conducted based upon analysis of AIS-data from the year 2016. The total amount of time the vessel that arrived or departed from the selected ports are measured and classified as active or idle time. The majority of the idle time is when the vessel is entering the anchorage area which means that the idle time occurs under an “inward voyage”. The fact is that more than two vessels are often calling to a refinery at the same time, thus the build-up starts. Every ship owner or charter want as many sailing days pr. ship since this when they are making their money, not when the ship is at anchor, also known as idle time. The paper presents the extent of idle time in oil ports by the use of AIS data.
The study is performed on two ports, one in Sweden and one I Norway. The paper presents a comperative study between ports in Norway and Sweden. In Sweden the choice of port landed on Brofjorden, an oil port owned by the largest fuel company in Sweden, Preem AB (Preem AB, 2017). In Norway Slagentangen refinery owned by Norwegian Esso was selected.
