O link que coloquei abaixo explica estes dois conceitos nestes termos:
"As the cargo operation is taken as the initial point of the design conception, the expected final product is a ship able to safely take loading rates as high as 16,000 tons of ore per hour, with each hold loaded in ***one pour*** and the ship fully loaded in ***one pass***, resulting in fewer pours into the holds of the ore carrier, faster loading operations and, consequently, a significant economy for the ship owner and for the port." |
