What is a main concern of OBO vessels?

A significant concern for OBO (Ore/Bulk/Oil) vessels revolves around damage to tank coatings and the high stresses these ships experience during their varied cargo operations. OBO vessels are designed to transport multiple types of cargo, including dry bulk (like ore) and liquid cargo (like oil). This dual capability means that the vessel's tanks are frequently switched between different types of cargo.

When these tanks are used for transporting oil, they require specialized coatings to prevent corrosion and damage that can be caused by the oil. The transition to carrying different cargo types, particularly dry bulk, can subject the tank coatings to wear and tear that may not be compatible with all cargoes, increasing the likelihood of damage. Additionally, OBO vessels often endure high stresses due to the nature of their cargoes and the loading/unloading operations, which can impact the ship's structural integrity and lead to further complications.

Understanding these concerns is crucial for maintaining the vessel's safety and operational efficiency, as well as ensuring compliance with regulations related to cargo handling and environmental protection.
