foreign invasive species across the oceans. This spreading
of species has been recently identified by the IMO as
one of the four greatest threats to the world’s oceans. In
addition, the vessels carry the NAUT-AW notation that
indicates the vessels are equipped to avoid bridge system
failures by addressing both technical and human-related
issues, with a particular emphasis on tasks related to
navigation in narrow and congested waters, as well as
areas with complex offshore infrastructure.
Statistical data have shown that grounding and
collisions account for almost 50 per cent of all serious
shipping incidents and the majority of these are
categorised as being due to human error. l
