Taktiskt ruttutbyte / Tactical route exchange

Thornberg, Markus, Manukyan, David January 2017 (has links)
Den tekniska utvecklingen har gjort att nya möjligheter har tillkommit för att säkra framförandet av fartyg och effektivisera ruttplaneringen. Ett av de effektiviseringssäten som för närvarande utvecklas är ruttutbyte. Syftet med studien är att med hjälp av ett simulerat scenario samt frågeformulär belysa eventuella risker förknippade med ruttutbyte till sjöss. Studien speglar deltagarnas upplevelse av den kritiska situationen som simuleringen återger och visar även skillnaden i beslutsfattandet mellan erfarna och oerfarna navigatörer. Tidigare forskning betonar till stor del fördelar med taktiskt ruttutbyte men mindre angående nackdelar med systemet. Med hjälp frågeformulär insamlades deltagarnas erfarenheter och upplevelser angående taktiskt ruttutbyte. Enligt scenariot var det planerat att ett av fartygen i trafikflödet skulle avvika från sin planerade rutt. Ruttutbyte har simulerats genom att visa fartygsrutter i ECDIS. Resultatet av studien visar att det finns ett klart mönster mellan olika gruppers beslutsfattande och graden av pålitlighet till de i ECDIS visade rutterna för andra fartyg. Studien visar även att det finns en påtaglig risk för kollision om navigatörer följer ruttutbytet utan vidare kritisk granskning på grund av falsk trygghet. / The technical advances in the maritime sector have led to new possibilities to secure the safe passage of the vessels and improve the process of route planning. One example of such advances is route exchange. The purpose of this study was by means of simulation to pinpoint whether there are any probable risks connected with the tactical route exchange. This study reflected the experience of the participants of the critical situation portrayed in the simulation. It also takes in to account the difference of the decision-making between the different groups. These groups are composed of experienced navigators and unexperienced navigators. The study also describes the simulation from a fact-based standpoint. Earlier research describes mostly advantages of the tactical route exchange and in less degree the disadvantages of the tactical route exchange. The study has been composed by means of simulation at several occasions. With the help of questionnaires, a general picture has been compiled of the participants’ background, experience and the general opinion about the tactical route exchange. According to the prepared scenario there was one vessel which was intended to deviate from its intended route. The route exchange was projected in the ECDIS console. The result shows that there is a pattern between the different groups´ decision-making and the degree of reliability of the projected routes. The study also points out the obvious risk of collision dependent on the incompleteness of the system and weaknesses for the worst-case scenario which should be taken into account in the future upgrades of the system.
