Assessment of the safety of ship navigating on
NowyŚwiat Canal was carried out based
on two
navigationsafetycriteria,recommendedin[4,5]:
1. Underkeelclearance,
2. Dimensions of the ship’s manoeuvring area
(minimalwaterwaywidth).

Analyses of the results of the empirical method

Minimal underkeel clearance for the maximal
vessel is equal to max. 1,04 m. This reaffirms the
port’s regulations rule requiring speed reduction by
the Port’s Captain to secure the lock and
subsequently, the portspecific harbour
conditions[13].
The
findings suggest that the parameters of the
methodofconstantclearancemightrequirechangeso
thatthesafetydepthconditionasasumoftheactual
ship’s draught (4,5 m for max vessel) and uderkeel
clearanceisfulfilled(butatawaterlevelofmorethan
500 cm). The results
derived from the probabilistic
method and modelling presented in [5,15,16]
confirmedtheabovefindingswiththevalueof0,08m
(the mean exploited underkeel clearance). Further,

The above tabulation provides data and
can be
used to assess the minimal safety width (a 47,05m
mean) for the maximal vessel operating one‐way
betweenVistula Lagoonand GdańskGulf. Thetwo‐
way waterway traffic analysis found the same
outcomes,leadingtotheconclusionthatutilizingthe
empirical method for width waterway analysis
confirms safety
