Shadow Fleet Accounts For Majority Of Strait Of Hormuz Transits

Strategic Transits Under Siege

A tanker operated by Greece-based Dynacom Tankers Management exited the Middle East Gulf through the Strait of Hormuz, highlighting limited activity among conventional oil carriers in the region. Transit volumes remain low as geopolitical tensions continue to affect shipping flows through one of the world’s key energy routes.

Mainstream Vs. Shadow Fleet Dynamics

Data from Lloyd’s List Intelligence show that the Malta-flagged suezmax Marathi arrived in India’s Gulf of Kutch on March 26. The vessel had previously transited the strait on February 28 and loaded 1 million barrels of crude from Ras Tanura. Marathi became the 10th non-shadow fleet tanker to exit the strait since March 8, indicating reduced activity among traditional operators.

Control And Revenue Through The ‘Tehran Toll Booth’

Shipping data indicate that part of the traffic is being routed near Iranian-controlled waters around Larak Island. Industry sources describe this route as increasingly influenced by the Islamic Revolutionary Guard Corps. Reports suggest some operators have faced pressure to comply with local conditions, including financial demands, although details vary across sources.

Dynacom’s Navigation Through Uncertain Waters

George Prokopiou said the transit was completed without payment and credited the crew’s actions. Another Dynacom vessel, Pola, has also completed passages through the area, reflecting continued operations despite elevated risks.

Broader Implications For Global Energy Supply

Around 20% of global oil shipments pass through the Strait of Hormuz, making disruptions in the area significant for energy markets. Some vessels have reduced tracking visibility or adjusted routes, while activity linked to non-traditional fleets has increased.

Conclusion

Ongoing tensions in the region continue to affect shipping through key maritime routes. Activity by conventional tanker operators remains limited, while alternative fleets play a larger role in current transit flows. These conditions introduce operational risks and uncertainty for energy transport. Market participants continue to monitor developments that may affect supply flows and pricing.

OpenAI Brings Unlimited Text Chats To Free ChatGPT Users

Unlimited Text Conversations Roll Out

OpenAI is removing limits on text-based conversations for all ChatGPT users, following the platform’s recent milestone of surpassing one billion weekly users.

The update introduces GPT-5.6 Luna as the default model for Free and Go users, replacing GPT-5.5.

New “Think” Button For More Complex Questions

Alongside unlimited text chats, Free and Go users will gain access to a new “Think” button, allowing them to use additional reasoning power for more complex queries.

OpenAI noted that separate usage limits will continue to apply to file uploads, image generation, voice features and other multimodal tools.

Faster Responses For Paid Subscribers

The update also brings improvements for ChatGPT Plus and Pro subscribers. They will receive access to GPT-5.6 Sol, an upgraded model designed for everyday tasks such as web research, planning, writing, decision-making and answering questions. According to OpenAI, the model delivers shorter, more robust responses.

The company noted that this version is separate from the GPT-5.6 Sol model used in Codex and Work, which remains unchanged. Plus and Pro subscribers will also receive a new thinking slider, allowing them to adjust how much reasoning the model applies before generating an answer, depending on the complexity of the task.

OpenAI Reports Fewer Errors

According to OpenAI’s internal testing, GPT-5.6 Luna produces 62% fewer factual errors than GPT-5.5 Instant, while GPT-5.6 Sol reduces factual errors by 68%.

The updated GPT-5.6 Sol model is available to Plus and Pro users starting today. The remaining features for Free and Go users will roll out throughout the week, with unlimited text chats and the new Think button becoming available next week.
