The development of crude oil tankers from single hull to double hull configurations represents one of the most significant advancements in maritime safety and environmental protection. This evolution was not driven by commercial or operational efficiency alone, but was a direct regulatory response to catastrophic oil spills that highlighted the inherent vulnerabilities of the single hull design. The transition, mandated by the International Maritime Organization (IMO) through MARPOL Annex I, has fundamentally reshaped tanker design, construction, and operation.
