(Master thesis; Mastergradsoppgave, 2019-05-31)The mandatory Polar Code is now set into force with strengthened requirements for vessels operating in polar waters. There are many challenges, and the polar environment adds an increased risk level. The preventive actions towards mitigating risks are more important due to the harsh environment, long distances and limited options for assistant rescue. Most accidents and incidents have pre-occurring ... -
Lean Production og sikkerhet i forsvarsindustrien. En teoretisk fortolkende casestudie av en norsk forsvarsbedrift
(Master thesis; Mastergradsoppgave, 2019-05-31)I følge Arbeidstilsynet er industrien en næring med mange registrerte skader og ulykker, og er en av fire næringer med flest arbeidsskadedødsfall. Bedrifter tilknyttet forsvarsindustrien håndterer blant annet ammunisjon, kjemikalier, sprengstoff og eksplosiver. Feil i denne type industri kan derfor medføre ulykker med alvorlige konsekvenser for liv, helse og miljø, og er dermed avhengig av et høyt ... -

Advocates of resilience argue that in a high risk environment, resilience is necessary for organization to avoid potential disasters and to prevent smaller events from escalating (Weick & ... -
Generisk beredskap - adekvat for å håndtere den neste store krisen? En casestudie av beredskap for hendelser med lav sannsynlighet-høy konsekvens i en kommune
(Master thesis; Mastergradsoppgave, 2019-05-31)Norgeshistorien er full av større naturhendelser, ulykker og kriser, det være seg både samfunns- og menneskeskapte. Vi ser at fokuset på disse har økt i nyere tid, særlig etter terrorangrepene i regjeringskvartalet og på Utøya 22. Juli 2011. Forberedelsene for å unngå slike hendelser, håndtere de dersom de skulle inntreffe og gjenoppreise samfunnet i etterkant, er en oppgave som jobbes med både ... -

Unprecedented Vessel-Icing Climatology based on Spray-Icing Modelling and Reanalysis Data: A Risk-Based Decision-Making Input for Arctic Offshore Industries
(Journal article; Peer reviewed, 2019-04-11)Marine icing is considered a major concern for vessels operating in the Arctic Ocean. Interaction between vessels and waves is the major source of sea spray that, under certain conditions, can lead to ice accretion on the vessels and thus create hazardous situations. Various models have been developed for the estimation of ice accretion rate using meteorological and oceanographic parameters. Various ... -
