Ballast tanks

Nov 17, 2016 · There are 12 main water ballast tanks (WBTs) onboard, which line up with the 12 main cargo oil tanks (COTs). Six of each on each side. The WBTs are empty when the ship is loaded with cargo, and are filled with seawater as cargo is discharged to keep the ship at a safe draft. They wrap around the cargo tanks, effectively acting as a double-bottom.

Sep 15, 2023 · Ballast Tanks. Ballast tanks are at the heart of any ballasting system. These containers hold the ballast material, and their design and functionality play a pivotal role in the ballasting process. Ballast tanks are situated at different parts of the ship to reduce the stresses onboard the ship due to movements like rolling or pitching. Pumps ... The first is a variable ballast system. This system consists of two pressure tanks. One is in front of the pressure hull and the other is near the batteries the back (both inside the exostructure.) They will be variable by 200kg.
