“…sailing in harbours, requires continuous adjustment of speed and course, monitoring ship systems, and communicating with both crew and external contacts. These scenarios range from the monotone to the highly complex (Norros, 2004;Nilsson et al, 2009). Maritime accidents occur in either scenario (Nilsson et al, 2009), mostly as the result of human error.…”

“…These scenarios range from the monotone to the highly complex (Norros, 2004;Nilsson et al, 2009). Maritime accidents occur in either scenario (Nilsson et al, 2009), mostly as the result of human error. Research shows that 49 to 96 percent of all shipping incidents or marine causalities are caused by human error (Rothblum, 2000;Hetherington et al, 2006;Tzannatos, 2010).…”

We present an experiment investigating concepts of affective state and workload in a large ship manoeuvring context. It is run on a consumer ship simulator software where student participants (N=31) perform two ecologically valid scenarios: sailing on open sea and in a harbour. Results from surveys show highly significant changes in terms of both affect and workload between the scenarios. Thus, one should consider varying affects and workloads from users in varying contexts, consequently demanding new design paradigms for product development, such as dynamically adaptive interfaces.

“…The ships today are technologically advanced and highly reliable (Rothblum et al 2002;Stoop 2003). Still, statistics are indicating that not only is the number of shipping accidents increasing but also the reason may well be the advanced technology, as well as human factors (Nilsson, Gärling, and Lützhöft 2009;Bambulyak and Frantzen 2011). In Norwegian waters, at least 8 out of 88 groundings in 2006 were influenced by watchkeepers falling asleep (Gould and Koefoed 2007).…”

Common patterns in aggregated accident analysis charts from human fatigue-related groundings and collisions at sea

Research has shown that there are potentially disastrous outcomes of human fatigue at sea. The conditions in which the seafarers have to operate are becoming more and more demanding. The study in this article attempts to aggregate accident charts derived from in-depth studies of human fatigue-related accidents to determine common patterns of interlinked fatigue factors. The accidents are analyzed by means of the Cognitive Reliability and Error Analysis Method (CREAM), which in the article has been modified for maritime accidents. The main fatigue factors identified are 'shift work', 'irregular working hours', 'inadequate task allocation', and 'excessive demands'. The study reveals several differences between ship collision and grounding accidents and their corresponding fatigue factors. Human fatigue-related collision accidents are characterized by wrong/badly timed decisions, misconceptions, and poor communication between the vessels. Right before the collision the crew is often panicking and mistakes are easily made. In human fatigue-related groundings, the conditions are often monotonous and the navigating officer has either overlooked the upcoming seabed or simply fallen asleep. Safety climate issues are also identified as important contributors to human fatigue.

“…Indeed, this aspect has been investigated through various experimental simulation studies, where it was concluded that technology advancements related to information collation and processing proved to be beneficial, that is, reduction in total response time when experience and familiarity with the encountered situation are less, as well as better course‐keeping performance in terms of efficiency with significantly lower cross‐track error and smaller maneuvering actions (Aarsæther & Moan, ; Gould et al., ; Nilsson, Gärling, & Lützhöft, ). Furthermore, the inclusion of decision support systems, such as automated course planning, has contributed successfully in decreasing the cognitive effort required to generate the path and offer advice to the navigator regarding the best solution to implement in certain situations (Cummings, Buchin, Carrigan, & Donmez, ; Xue, Clelland, Lee, & Han, ).…”

Poor lookout, lack of situation awareness, and delayed response have been continuously recognized as contributory causes of navigation accidents (i.e., collisions and groundings). It is claimed that such negative behavioral characteristics can be corrected when the navigation system is equipped with the automation capability to intervene upon their detection. Building on the results of my previous work, this study sets the starting line in exploring this technological innovation under a conceptual framework, where it is attempted to employ simple, quantifiable, and measurable ways to assess the deck officer's (navigator's) complex aspect of mental task reliability. To deal with this challenge, the navigator's behavior when performing navigation tasks is described by the Markov method and the uncertainty, ambiguity, and weakness in perceiving accurately the environment and traffic conditions is determined by fuzzy logic. The proposed concept is demonstrated through its practical application in collision and grounding accidents, where it is argued that further research is required for its validation.
