Abstract: |
In this paper we will present a simple
but reliable methodology for short term prediction
of a cruise ship behaviour during manoeuvres. The methodology is quite general and could be
applied to any kind of ship, because it does not require the prior knowledge
of any structural or mechanical parameter of the ship. It is based only on
the results of manoeuvrability data contained in
the Manoeuvring Booklet, which in turn is filled
out after sea trials of the ship performed before his delivery to the owner. We developed this method to support the
investigations around the Costa Concordia shipwreck, which happened near the
shores of Italy in January 2012. It was then validated against the data
recorded in the “black box” of the ship, from which we have been able to
extract an entire week of voyage data before the shipwreck. The aim was investigating
the possibility of avoiding the impact by performing an evasive manoeuvre (as ordered by the Captain some seconds before
the impact, but allegedly misunderstood by the helmsman). The preliminary
validation step showed a good matching between simulated and real values
(course and heading of the ship) for a time interval of a few minutes. The fact that the method requires only
the results registered in the VDR (Voyage Data Recorder) during sea trial
tests, makes it very useful for several applications. Among them, we can cite
forensic investigation, the development of components for autopilots, the
prediction of the effects of a given manoeuvre in
shallow water, the “a posteriori” verification of the correctness of a given manoeuvre and the use in training simulators for ship
pilots and masters. |
