Maritime Industry Briefing: Shadow Fleet Oil Spill, Hormuz Shuttling Revival, and Europe's River Crisis

## Shadow Fleet Tanker Leaks Oil Off Oman Coast A sanctions-hit vessel linked to the so-called 'shadow fleet' is leaking oil off the coast of Oman, with satellite imagery showing the spill has spread significantly in recent days, according to gCaptain. Shipping specialists analysing the imagery have raised growing concerns about potential environmental damage to coastal areas in the region. The incident underscores the mounting risks associated with ageing, under-insured tankers operating outside conventional regulatory frameworks to move sanctioned crude. Shadow fleet vessels frequently lack adequate insurance coverage and maintenance standards, making spill response and liability recovery deeply problematic for affected coastal states. ## Hormuz Oil Shuttling Picks Up After Lull The ship-to-ship oil transfer operations that have become critical to moving crude cargoes through the Strait of Hormuz are picking up again following a recent slowdown, gCaptain reports. The shuttling trade — in which cargoes are transferred between vessels to circumvent restrictions or logistical constraints near the strait — has helped move millions of barrels as hostilities in the broader Middle East region continue to escalate. The revival of this activity signals sustained demand pressure on alternative routing solutions, and traders and operators will be watching closely for any further disruption to one of the world's most strategically vital energy chokepoints. ## Europe's Shrinking Rivers Hit Transport and Power Output Record low water levels across Europe's major river systems are causing significant disruption to inland waterway freight, electricity generation, and corporate earnings, according to gCaptain. Searing heat and erratic rainfall patterns have combined to reduce navigable depths on key arteries including the Rhine, Danube, and Elbe, forcing operators to reduce vessel loads or suspend sailings entirely. The knock-on effects extend beyond shipping: hydroelectric output has fallen and industrial supply chains reliant on river transport — including bulk commodities such as coal, grain, and chemicals — are facing mounting cost pressures. The situation is stoking broader fears about the long-term economic consequences of climate-driven hydrological change for European industry and energy security.
