Active learning for enhanced understanding of "ship damage stability"
(Journal article; Tidsskriftsartikkel, 2018)Active Learning has always played an important part of seamen’s education. Transfer of experience have from ancient time been practiced in an active learner-centered field where unexperienced seamen got involved in their own learning by being supervised by experienced seamen, when practicing seaman related activities. This learning practice was supreme before the introduction of “modern” maritime ... -
Analysis of the impact of deploying thermal protective immersion suits on evacuation time for passenger ships operating in polar waters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-22)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, international standards require that TPIS can be donned within 2 min and that walking speeds are reduced by no more than 25%. Clearlythese requirements are arbitrary and do not ... -
Biosignal-Based Driving Skill Classification Using Machine Learning: A Case Study of Maritime Navigation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-19)This work presents a novel approach to detecting stress differences between experts and novices in Situation Awareness (SA) tasks during maritime navigation using one type of wearable sensor, Empatica E4 Wristband. We propose that for a given workload state, the values of biosignal data collected from wearable sensor vary in experts and novices. We describe methods to conduct a designed SA task ... -
An experimental analysis of the impact of thermal protective immersion suit and angle of heel on individual walking speeds
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-16)Background: Incarcerated individuals have poor mental health compared to the general population. Social support has a benefcial efect on mental health. The bufering model proposes that social support facilitates coping under stressful conditions, while the main efects model suggests that belonging to social networks and having positive social interactions are benefcial for mental health. Prisons ... -
Factors influencing the time required to don thermal protective immersion suits correctly
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-10)The cold environment in polar regions introduces additional challenges when abandoning passenger vessels and offshore facilities. The International Maritime Organization Polar Code requires vessels operating in polar regions to be equipped with approved thermal protective immersion suits (TPIS) that can be donned unassisted within 120 s. As time is critical during an evacuation, quantifying the Net ... -
Kinematic motion models based vessel state estimation to support advanced ship predictors
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-14)Advanced ship predictors can generally be considered as a vital part of the decision-making process of autonomous ships in the future, where the information on vessel maneuvering behavior can be used as the source of information to estimate current vessel motions and predict future behavior precisely. As a result, the navigation safety of autonomous vessels can be improved. In this paper, vessel ... -
Maritime safety and the ISM code: a study of investigated casualties and incidents
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-08-27)Abstract In 1993, the International Maritime Organization adopted the International Safety Management (ISM) Code which requires all shipping companies operating certain types of vessels to establish safety management systems. Nevertheless, two decades later, maritime safety remains a concern. This article studies 94 maritime cases investigated by the Maritime Accident Investigation Branch in the ... -
A methodology for collecting donning times of thermal protective immersion suits intended to be worn by passengers on vessels operating in cold environments
(Journal article; Tidsskriftartikkel; Peer reviewed, 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, in particular those requiring the abandonment of the vessel. As emergency abandonment is a time critical process, it is essential to consider the time required to correctly don the ... -
Noise-intensification data augmented machine learning for day-ahead wind power forecast
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-10)The day-ahead wind power forecast is essential for the designation of dispatch schedules for the grid and rational arrangement for production planning by power generation companies. This paper specifically investigates the effect of adding noise to the original wind data for forecasting models. Linear regression, artificial neural networks, and adaptive boosting predictive models based on ... -
Possible COLREGs Failures under Digital Helmsman of Autonomous Ships
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-19)Autonomous navigation will play an important role in the future of the shipping industry. Hence, this study illustrates several concepts that should support the navigation side in relation to the collision avoidance of autonomous ships. The concept of system intelligence, i.e., cloned by human navigators, as the digital helmsman to navigate future vessels is discussed in the first part of this study. ... -
Safety challenges related to autonomous ships in mixed navigational environments
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-30)Digitalization and technological advancements have accelerated the development and emergence of autonomous and remotely controlled ships in the maritime transport sector. This type of vessels consists of highly intelligent and adaptive functionalities, equipped with a variety of external sensors and actuators to gain situation awareness, automated control and adaptive maneuvering for achieving more ... -
Way-finding on-board training for maritime vessels
(Journal article; Peer reviewed, 2018-01-03)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 crew. In fact, international maritime regulations require that all personnel employed or engaged on a seagoing ship receive proper familiarization training. However, several studies ...
