U.S. forces disabled an unladen oil tanker in the Gulf of Oman on Monday after it attempted to sail to an Iranian port in violation of the ongoing blockade against Iran, the U.S. military said.U.S. Central Command said in a post on X that the M/T Marivex, a Palau-flagged vessel, was transiting international waters in the Gulf of Oman toward Iran when it was targeted.An F/A-18 Super Hornet from the USS Abraham Lincoln fired a precision munition into the ship's engineering and steering spaces after the crew failed to comply with directions from U.S. forces, CENTCOM said."Marivex is no longer sailing to Iran," it said.

A dual fuel combustion system developed by Oak Ridge National Laboratory (ORNL) in collaboration with Caterpillar Inc. addresses the challenge of methanol ignition in diesel engines, with clear relevance for inland and coastal marine vessels.Methanol is typically produced from natural gas, an abundant domestic resource, and converting it into a liquid allows easier storage and handling. However, methanol does not ignite easily, creating a barrier for vessels that rely on compression-ignition diesel engines.ORNL’s approach pairs methanol with a small amount of diesel used as a pilot fuel to start combustion, enabling methanol dual fuel operation across a much wider range of conditions.

Oil prices fell on Tuesday, erasing most of the previous session's gains, after Iran and Israel said they had halted attacks on each other following an appeal from U.S. President Donald Trump, though both sides warned they could resume hostilities.Brent crude futures LCOc1 were down $1.33, or 1.4%, at $92.92 a barrel at 0741 GMT, while U.S. West Texas Intermediate CLc1 declined $1.73, or 1.9%, to $89.57 a barrel.The market has been here before, said PVM Oil Associates analyst Tamas Varga, referring to hopes for an end to hostilities that could then end the three-month war in the Middle East.

Yemen's Iran-aligned Houthis said on Monday that they would ban Israeli maritime navigation in the Red Sea, adding to challenges for global shipping through the Middle East during the Iran war.The group said in a statement it had launched an attack on Israel and enacted a total ban on Israeli shipping in the Red Sea, warning of further escalation.Any Houthi attacks on Red Sea shipping would worry energy markets more than three months into Iran's closure of the Strait of Hormuz, with the war reigniting overnight.

In an open letter to the industry, ABS has set out a measured and data-driven approach to support the development of an effective global framework for maritime decarbonization.Titled, The ABS View: A Practical Path Forward on IMO Mid-Term Measures, it reflects broad alignment across the industry on the need for one international approach to emissions reduction, while recognizing that implementation will be shaped by real-world constraints across the global fleet.The thinking is based on the findings of a detailed ABS assessment of the key drivers influencing the industry’s transition.
