Analysis of the impact of deploying thermal protective immersion suits on evacuation time for passenger ships operating in polar waters
Azizpour, Hooshyar; Galea, Edwin R.; Deere, Steven; Erland, Sveinung; Batalden, Bjørn-Morten; Oltedal, Helle Asgjerd (Peer reviewed; Journal article, 2023)For passenger vessels operating in polar waters, the Polar Code requires that in case of possibility of immersion in polar waters, thermal protective immersion suits (TPIS) should be available for all passengers. Thus, ... -
Comparing the identification of recommendations by different accident investigators using a common methodology
Johnson, Chris W.; Oltedal, Helle Asgjerd; Holloway, C. M. (Journal article, 2012)Accident reports play a key role in the safety of complex systems. These reports present the recommendations that are intended to help avoid any recurrence of past failures. However, the value of these findings depends ... -
Distributed situation awareness in complex collaborative systems: A field study of bridge operations on platform supply vessels
Sandhåland, Hilde; Oltedal, Helle Asgjerd; Hystad, Sigurd William; Eid, Jarle (Journal article, 2015)This study provides empirical data about shipboard practices in bridge operations on board a selection of platform supply vessels (PSVs). Using the theoretical concept of distributed situation awareness, the study examines ... -
An experimental analysis of the impact of thermal protective immersion suit and angle of heel on individual walking speeds
Azizpour, Hooshyar; Galea, Edwin R.; Erland, Sveinung; Batalden, Bjørn-Morten; Deere, Steven; Oltedal, Helle Asgjerd (Peer reviewed; Journal article, 2022)The cold environment of Polar Regions introduces additional challenges to maritime safety in situations where it becomes necessary to abandon a vessel. The Polar Code requires all vessels operating in Polar Regions to be ... -
A methodology for collecting donning times of thermal protective immersion suits intended to be worn by passengers on vessels operating in cold environments
Brünig, Ria; Galea, Edwin R; Batalden, Bjørn-Morten; Oltedal, Helle Asgjerd (Peer reviewed; Journal article, 2021)Adequate thermal protection for passengers travelling on-board vessels in cold climate regions, such as that provided by thermal protective immersion suits (TPIS), enhances passenger survivability in emergency situations, ... -
Situation awareness in bridge operations – A study of collisions between attendant vessels and offshore facilities in the North Sea
Sandhåland, Hilde; Oltedal, Helle Asgjerd; Eid, Jarle (Journal article, 2015)This study examined accident reports (n = 23) for collisions between attendant vessels and offshore facilities on the Norwegian continental shelf during the period of 2001–2011. An initial analysis indicated that the concept ... -
Way-finding on-board training for maritime vessels
Tvedt, Sturle Danielsen; Oltedal, Helle Asgjerd; Batalden, Bjørn-Morten; Oliveira, Manuel Fradinho (Journal article; Peer reviewed, 2018)In the maritime industry, it is of vital importance that personnel onboard ships are familiarized with the ship’s layout, along with safety equipment and processes for safeguarding of the individual seafarer and the ship’s ...
