DeepDraft Weekly Maritime Brief | May 24, 2026: Hormuz Permission Risk Meets MEPC 84 Compliance Pressure

The Hidden Cost of Maritime Chokepoints: Hormuz, Malacca & Global Supply Chains

What really happens when a global maritime chokepoint is threatened? The industry often asks if ships can pass through the Strait of Hormuz, but the better question is what happens before they even try.In [http://try.In] this episode, we break down the cascading effects of geopolitical disruptions on the global shipping industry. We explore how a disrupted sea lane doesn't just delay vessels, it completely contaminates the next commercial decision, altering everything from crude oil chemistry to vessel employment.

DeepDraft Weekly Maritime Brief | May 24, 2026: Hormuz Permission Risk Meets MEPC 84 Compliance Pressure

Hormuz remains permissioned, with controlled routing, boarding risk and sanctions exposure still affecting commercial movement. MEPC 84 adds a separate compliance signal through the North-East Atlantic ECA, turning a new chart boundary into fuel planning, records and PSC exposure.

Saving the Oceans vs. Surviving a Ship Fire: The Truth About F3 Foams

Starting January 1, 2026, the International Maritime Organization (IMO) is banning firefighting foams containing PFOS, a toxic "forever chemical" on all ships worldwide. But is the maritime industry actually ready for the alternatives? In this episode, we dive deep into the tension between protecting the marine environment and ensuring shipboard fire safety. For decades, PFOS-based foams (like AFFF) were the gold standard at sea because they quickly formed a fuel-resistant film that thrived in harsh saltwater conditions. Now, they are being phased out globally due to their harmful, non-biodegradable nature.While eliminating "forever chemicals" is a massive win for our oceans, the new generation of Fluorine-Free Foams (F3) brings dangerous hidden risks. We explore why these new F3 foams lack the vital fuel-sealing film, making them highly sensitive to burnback and high winds out on the open deck. We also discuss why simply swapping the chemicals isn't enough, your ship's current proportioners and systems might not even be compatible with these new, thicker concentrates.

Command vs Conn: Why the Master’s Authority Is Never Shared

In pilotage waters, one misunderstood word can blur the line between advice and authority. This DeepDraft video looks at the common claim that a pilot “has the Conn” during pilotage. In merchant shipping, that phrase creates more confusion than clarity. The pilot advises. The Master commands. The Officer of the Watch executes under the Master’s authority. That distinction is not academic. It affects bridge team management, pilotage practice, SMS language, inspection findings, and legal accountability after an incident. The full article explains why command is continuous, indivisible, and never transferred, even when a compulsory pilot is onboard. It also explains why inspectors, auditors, and bridge teams should be careful with naval language that has no proper place in merchant ship pilotage procedures.

MEPC 84 Changed the Map, Not the Rule

A short DeepDraft technical briefing on what MEPC 84 actually changed for ships. The IMO Net-Zero Framework remains unresolved, but the North-East Atlantic ECA is moving toward enforcement from 2028. For Masters, Chief Engineers and operators, the issue is practical: fuel planning, changeover timing, tank segregation, MARPOL samples, engine-room records and Port State Control exposure.
