Acknowledgements

First I would like to thank my main supervisor Alfred Hanssen. I am very grateful for the opportunity I was given by you and Aker Solutions in Tromsø to work with such a relevant and exciting theme for my master’s thesis. Thank you for all of the advise, motivation and fruitful discussions. Also thank you to my co-supervisors, Gunnar Noer and Odd Erik Garcia, for much appreciated advise and help when needed. A huge thank you should also be extended to Chantal Claud for providing me with the data set that formed the entire basis for my thesis. Allowing me to use this data set is highly appreciated. During my work I received help with various tasks, and for that I wish to express ap-preciation to the following persons: Robert Jenssen, Jonas Nordhaug Myhre and Georg Elvebakk. Thank you so much for taking the time to help me. To my family, thank you for all of your love and encouragement, and for always sup-porting me in any way you can, from food deliveries to tire changes! Last, but not least, my wonderful boyfriend Jon, thank you so much for your tremen-dous love and support, which literally stretched to great lengths- I don’t know what I would do without you
