HMI Measures for Improved Sensemaking
bridge systems. This would need to be aligned with the needs of the DPO, possibly
duplicating the display in several locations. The concerns were mainly related to
the fact that information needs vary across circumstances, thus the DPOs need to
be able to reorganize their screens. One of the interviewees felt that if there is an
inexperienced DPO on duty, the captain should take an active role in dictating HMI
layout arrangements.
critical SucceSS factorS
Participants agreed that the design should be clear and as simple as possible, with
great emphasis on early warnings and deviations from expected normal states. The
display should not feel cluttered, there might be a pitfall to include too much content
that is “ nice to have”.
iDeaS for imProving the SketcheS PreSenteD
One commented that perhaps wind presentation could be displayed to more clearly
announce changes in strength and/ or direction, e.g. could the wind arrows change
color to yellow when it is increasing. Many lower level components could perhaps
be presented using a collective “ traffic light” to enrich display content while saving
space. Using trended information as extensively as in the sketches seem promising, but they should not be too s mall – the alarms should be more clear. One speculated that maybe it would be a good idea if some information could be brought
up by the user based on the situation, such as the capability plot ( the sketches in
Figures 15. 8–15.10 actually indicates the possibility of selecting among predefined
“ views”, located at the bottom right). If a vessel is on Posmoor( atar) – a combination
of DP- and anchor-based position c ontrol – more information related to this should
be found on the display.
other inPut or SuggeStionS
All participants stressed the importance of improving the alarm situation. An overview display should acknowledge this challenge, aiming in its design to further
help DPOs notice and correctly diagnose various warnings and alarm situations.
Several of the participants were of the impression that DP is utilized more and
more in the petroleum domain. Some also expressed concern about management
( on shore) pushing operations too far, reducing the safety margins in order to maximize profits.
CONCLUSION AND FURTHER WORK
By analyzing DP-related incidents and interviewing experienced DPOs, captains and
instructors, we have found that there is a potential for making changes to the HMI
design in order to improve sensemaking. We have found that the challenges DPOs
face are similar to the ones operators in other safety-critical industries are experiencing, so there are apparent opportunities for the maritime domain to learn from how
