Have you ever wondered why oil tankers are made so large?
An oil tanker makes empty trips after unloading because it cannot load cargo. As the ship's size increases, its deadweight decreases based on the total weight it carries annually. For this reason, oil tankers are built with a large tonnage.
However, there’s a problem here! Let’s say you’ve loaded a 100,000-ton ship with oil. The ports it can enter are limited. Due to its draft, it can’t dock at every port. If there isn’t a tank available for 100,000 tons at the port it visits, you’ll be forced to struggle with STS operations.
In short, as the ship grows, so do the problems.
What if this ship could carry cargo on its deck as well?
What if, after unloading the oil, it could carry water in bags on its deck?
This would solve the issue of empty trips, and you would be able to transport oil more efficiently without building such a large ship.
By the way, there is no Oil-Water trade route today. You could become the key player in this new route.
