Oil Tanker
The biggest feature of the structural layout of the oil tanker is that there is a longitudinal bulkhead in the cargo oil tank. There is a longitudinal bulkhead at the center line of the small coastal oil tanker, which is divided into two horizontal cargo oil tanks: left and right. Large oil tankers are equipped with 2 to 3 longitudinal bulkheads, which are divided into 3 to 4 cargo oil tanks laterally. The function of the longitudinal bulkhead is to reduce the influence of the free liquid surface and increase the stability of the ship.
Nowadays, oil tankers are required not to adopt a single-hull structure, but should adopt a double-hull structure, that is, the bottom is a double bottom with a hopper tank, the sides are double-layered, and the deck is single-layered. Generally, each part is required to adopt a longitudinal frame type. Structure type. The oil tanker adopts a double-layer side structure, which not only increases the safety of the ship and reduces marine pollution, but the smooth inner surface of the oil tank makes it easier to clear the tank.
