Abstract The decreased ice extent caused by increased air and sea temperatures has led to a growing interest in the Arctic waters. There are different maritime industries that have plans to expand northwards for various reasons. First of all there are different developments in oil and gas industry in Barents, Kara, Greenland, Arctic sea around the coast of Canada and Alaska. New ship trading ...

Installations and vessels operating in the high North in the winter season are likely to be subjected to marine Icing. To date there are no sensor technology available to accurately measure the total weight or volume of the ice. Photogrammetry is a universal 3-D measuring technique applied in a wide range of interdisciplinary fields. Agisoft PhotoScan is a photogrammetry software utilizing Structure ...

The last years it has been an increasing global interest to reduce emissions of greenhouse gases to the atmosphere. One of the most important greenhouse gases is CO2. To reduce CO2 emissions carbon capture and storage (CCS) is the most realistic approach. With today’s technology absorption by an amine solution is the most developed and applicable method for post-combustion CO2 capture. But this ...

Offshore petroleum drilling in harsh and cold environment, like in the Barents Sea, can be challenging and risky due to the prevailing weather condition. How the physical environment affects systems, components, and working environment has to be enlightened in order to operate safely. The vulnerable environment, remoteness, and possible outcomes if an accident occurs are of great concern. The society, ...

In recent years several serious near-misses with major hazard accident potential have happened on the Norwegian Continental Shelf, many of them hydrocarbon leaks. Research has shown that many of these are caused by manual intervention. Despite this fact, current focus in QRAs and have been for a long time, are on technical systems. This is despite recent trends showing no decline in risk level. A ...

The thesis is done in co-operation with DNV GL Harstad and Schlumberger. DNV GL has provided access to historical accidents data, by using technical documents. Schlumberger has provided technical information about well testing and hazards related to such an event, and an internal risk analysis document, which they use in their operations. This document is modified to suit, and account, for arctic ...

Denne studien skal undersøke hvordan risikokommunikasjon om en terrortrussel og andre mekanismer kan påvirke individers risikopersepsjon av en terrortrussel. Å kommunisere om terrortrusler er utfordrende, ettersom det ligger i terrorismens natur å være en trussel som er uforutsigbar, tilfeldig, kompleks og som kan endre former og angrepsmetoder raskt (Norris et al., 2003). Terrorismens karakteristikker ...

The main purpose of this study was to contribute to understanding of how safety culture affects the performance of safety information systems (SISs). More particularly, to investigate how safety culture can both facilitate and inhibit a SIS to function effectively. The thesis has been carried out as a qualitative, single case study of an onshore facility in the oil and gas industry. Seven ...

Denne masteroppgaven ser nærmere på studien av risikopersepsjon som har til formål å vise at dette er et sentralt forskningsområde i samfunnet vårt. Som konsekvens av de økte klimaendringene ser vi som i min studie hvor sårbart Flåm som bygd kan bli i møte med uønskede hendelser som flom og hvor utfordrende det er for mennesker å imøtekomme flom som risiko. Hovedformålet med denne oppgaven er derfor ...

Oppgaven tematiserer formelle og uformelle læreprosesser i flyhangaren ved teknisk avdeling i et flyselskap. Feltarbeidet har blitt gjort på LT Tech AS ved Lufttransport AS’ hovedbase i Tromsø. Oppgavens problemstilling er «Hvordan bidrar uformelle læreprosesser i utviklingen av kyndighet og kompetanse hos teknisk personell i LT Tech AS?» I luftfart stilles høye krav til sikkerhet. Så lenge luftfarten ...
