Maritime Security Briefing: Shadow Fleet Under Fire, Hormuz Threat Escalates, and Training Failures Exposed in Bass Strait

## Maritime Industry Briefing: Security and Safety Risks Mount Across Key Waterways ### Ukraine Intensifies Drone Campaign Against Shadow Fleet Tankers Ukraine has dramatically escalated its campaign against Russia's so-called 'shadow fleet,' with Ukrainian drones striking approximately a dozen tankers over a 48-hour period, according to gCaptain. The vessels were reportedly delivering fuel to Crimea as Kyiv intensifies efforts to sever supply lines to the Russian-occupied peninsula. The strikes represent a significant uptick in Ukraine's maritime interdiction strategy, targeting the opaque network of tankers that Western governments allege has been used to circumvent sanctions on Russian energy exports. The attacks underscore the growing vulnerability of vessels operating in the Black Sea region and raise fresh questions about the insurance and flag-state exposure of ships participating in shadow fleet operations. ### Strait of Hormuz Threat Level Raised to 'Severe' The Joint Maritime Information Centre (JMIC) has elevated its threat assessment for the Strait of Hormuz to 'severe' — its highest category — following a recent series of incidents in the waterway, Seatrade Maritime reports. JMIC indicated that an attack on commercial shipping in the strait is now considered 'highly likely.' The Strait of Hormuz remains one of the world's most critical maritime chokepoints, with an estimated 20% of global oil trade transiting the passage. A severe threat designation will likely prompt operators to review transit procedures, increase naval escort requests, and reassess war-risk insurance premiums for vessels calling at Gulf ports. Shipowners and operators are advised to consult the latest JMIC advisories and flag-state guidance before scheduling transits. ### ATSB: Training Gaps Left Cargo Vessel Adrift in Bass Strait In a separate safety development, Australia's Transport Safety Bureau (ATSB) has published findings revealing that a cargo ship was left without steering for more than eight hours in the Bass Strait after crew members were unable to operate an available backup steering system — due to inadequate training, according to gCaptain. The incident highlights a persistent and industry-wide concern: that emergency equipment is only as effective as the crew's ability to deploy it under pressure. The ATSB's findings are expected to prompt renewed scrutiny of onboard emergency drills and competency verification procedures, particularly for vessels operating in the challenging conditions of the Bass Strait. The bureau's report serves as a timely reminder that human factors and training deficiencies remain among the leading contributors to serious marine incidents, even when technical redundancies are in place. --- *Sources: gCaptain, Seatrade Maritime.
