Shipping Industry Issues Stark New Hormuz Transit Guidance as Risks Mount<\/p>\n
The global shipping industry has released sweeping new guidance for vessels transiting the<\/p>\n
, warning that even if the waterway remains technically open, conditions inside the chokepoint may still be too dangerous for safe navigation.<\/p>\n
, issued jointly by major industry groups including\u00a0BIMCO,\u00a0International Chamber of Shipping,\u00a0INTERTANKO,\u00a0OCIMF,\u00a0INTERCARGO, and\u00a0IMCA, paints one of the clearest pictures yet of the deteriorating operational environment facing merchant ships in and around the Strait of Hormuz.<\/p>\n
The document warns that vessels may face a \u201chigh workload and high-stress operating environment\u201d where kinetic threats, electronic warfare, heavy congestion, mines, drones, AIS spoofing, and navigation hazards could all occur simultaneously.<\/p>\n
\u201cTransit planning must consider both security risk and navigational risk,\u201d the guidance states.<\/p>\n
The advisory comes as commercial shipping through Hormuz remains severely disrupted following months of conflict involving the United States, Israel, and Iran. Industry organizations said Masters and ship operators should continuously reassess whether a transit is necessary at all.<\/p>\n
\u201cWhen based on the latest security threat assessment, should the risk be increased, then deferment of transit should be considered a safer option,\u201d the document states.<\/p>\n
One of the most striking warnings involves the possibility of extreme congestion should transit windows suddenly reopen after periods of closure or heightened threat.<\/p>\n
The guidance says large numbers of vessels attempting simultaneous passages could create \u201cchain-reaction manoeuvres,\u201d unstable CPA calculations, hazardous overtaking situations, and increased grounding or collision risks in the narrow Traffic Separation Scheme.<\/p>\n
Operators are warned that reduced military oversight and limited salvage capability could leave ships largely on their own if propulsion or steering failures occur inside the transit corridor.<\/p>\n
The guidance also highlights persistent concerns over electronic warfare in the region. Industry groups warned that attackers have used AIS spoofing to inject false vessel targets into navigation systems in an effort to manipulate ship movements.<\/p>\n
\u201cVisual and radar observations must be prioritised,\u201d the document says.<\/p>\n
The guidance instructs vessels to prepare for the \u201ctotal unavailability \u2014 or unreliability \u2014 of the GNSS signal for the entirety of the transit,\u201d recommending continuous dead reckoning, radar plotting, paper charts, and manual position fixing.<\/p>\n
\u201cNo single position is universally safe,\u201d the guidance warns in its section on waiting areas and anchorages.<\/p>\n
Among the more unusual recommendations, operators are advised to consider disabling Bluetooth, Wi-Fi, and location services on personal mobile devices amid fears that connected devices could leak vessel position data.<\/p>\n
The document also outlines detailed operational recommendations for bridge teams, including:<\/p>\n
Master or Chief Officer continuously on the bridge<\/p>\n
Dedicated radar plotters and lookouts<\/p>\n
Manual steering where conditions warrant<\/p>\n
Enhanced fatigue management procedures<\/p>\n
Pre-transit drills for GNSS failure, propulsion loss, steering failure, and security incidents<\/p>\n
The advisory further warns of continued risks from unmanned surface vessels, limpet mines, combat swimmer sabotage, missile and drone attacks, unexploded ordnance, and possible errant mines remaining in the water following clearance operations.<\/p>\n
Ships are also advised to maintain at least a 30-nautical-mile separation from U.S. military vessels and to avoid major course alterations or speed reductions during transit unless absolutely necessary.<\/p>\n
Notably, the industry guidance acknowledges that both northern and southern routes through the Strait may carry mine risks, underscoring the lack of any fully secure corridor.<\/p>\n
The advisory stops short of issuing a formal \u201cgo\/no-go\u201d recommendation, but it establishes a decision framework that strongly encourages operators to defer transits if recent kinetic activity, electronic interference, traffic compression, crew fatigue, or unresolved security concerns materially degrade navigational safety.<\/p>\n
The document repeatedly emphasizes that the safety of life at sea remains the overriding priority.<\/p>\n
