A dutch maritme pilot is boarding a ship to set course in to the Port of Rotterdam.
We are operating 24/7 - 365 days a year to make sure that the ships get in to and out off the port safely.
Using pictures and sketches, this video finally explains the difference between gross tonnage (GRT) and net tonnage (NRT); the ship spaces that are included/excluded in their calculation; and the importance of these terms to ship owners.
Contents of this video will benefit mariners preparing for exams (written and oral examinations).
