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.

Following the divestment of Wärtsilä Water & Waste to Solix Group AB, Hamworthy recently launchedas an independent specialist in marine water and waste systems. The business enters its next chapter with full operational continuity for customers worldwide, bringing together more than a century of engineering heritage, established installed-base expertise and global lifecycle support capabilities under the historic Hamworthy name.The launch marks the return of Hamworthy as a standalone marine environmental systems company and brand, with Serck Como, the freshwater generation business previously operating within Wärtsilä Water & Waste, continuing as Serck Como – A Hamworthy Business.

Anemoi Marine Technologies and its partners have completed a joint development project aimed at simplifying the integration of Rotor Sail wind propulsion systems on medium-range (MR) tankers, with classification society DNV granting Approval in Principle (AiP) for the design.The project was developed in collaboration with Guangzhou Shipyard International (GSI) and tanker operator Hafnia and focused on integrating two folding, explosion-rated Rotor Sails into an MR tanker design.The approval provides shipowners with a verified design basis for installing wind-assisted propulsion systems on product tankers, a vessel segment where deck space

Hydrogen of Dutch Origin (H2DO) and its partners have launched a feasibility and concept study for a 30-50 MW offshore green hydrogen project in the Dutch North Sea, aimed at demonstrating how offshore hydrogen production could support the expansion of offshore wind capacity while reducing pressure on onshore infrastructure.The study, funded under the Dutch Topsector Energie (TSE) program, will evaluate the development of an offshore hydrogen production facility connected to shore by pipeline.
