The maritime sector frequently refers to a 'shadow fleet', also known as a 'dark fleet', to describe a specific category of vessels. These include tankers and various support ships engaged in methods designed to conceal the actual origin, ownership, or final destination of the cargo they carry.
Such practices are typically employed when moving sanctioned or high-risk commodities, aiming to circumvent regulations or avoid scrutiny. While this definition is widely understood within industry circles, it is important to note that the term 'shadow fleet' lacks a formal legal definition or official governmental listing.
This lack of legal codification and the inherent clandestine nature of its operations contribute significantly to the difficulty in accurately identifying and counting the vessels that constitute this fleet, as reported by Hellenic Shipping News Worldwide.
