4) Conclusion
Until the day when bathymetric data are portrayed in ENCs with greater density (so that the safe draft always
coincides with a depth contour) each company should choose for itself one of the above workarounds after it
weighs each one's advantages and disadvantages.
It is worth clarifying the fact that the main tool to clearly distinguish between safe and
unsafe waters remains the No-Go Area manually plotted by the navigator.
INTERTANKO, along with other industry stakeholders, will push regulators to legislate measures which will
solve the problem.
