Exmar has taken delivery of MGC ANTWERPEN, deemed by the Belgian shipping company as the world's first oceangoing vessel powered by a dual-fuel ammonia engine.The newbuild mid-size gas carrier is capable of carrying up to 46,000 cubic meters of ammonia or liquefied petroleum gas and can operate with close to zero emissions when fueled by low-carbon ammonia.Exmar said the vessel was developed in collaboration with HD Hyundai Heavy Industries, WinGD, Nord Gas Solutions and Lloyd's Register.

Compute Maritime, the deep tech company behind NeuralShipper, the world's first Al platform for ship design, has revealed the results of its UK Government-funded project, GenDSOM, to bring generative Al and additive manufacturing into ship design.Working with consortium partners Siemens Digital Industries Software, Rapid Fusion, HP, BYD Naval Architects and the University of Southampton, the project has produced a next-generation crew transfer vessel (CTV) for the offshore wind sector that, in detailed performance modeling, saves 101,671 liters of fuel and 258.7 tons of CO2 per vessel every year compared with a conventional baseline.The designed vessel, a 32.

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.

Caspian Offshore Construction (COC) has acquired an anchor handling tug supply (AHTS) vessel from Sinopacific Engineering & Contracting (SPEC), marking the first vessel in the SPA90 series to join the Kazakh offshore marine service provider's fleet.The shipbuilding contract was signed on April 30, 2026, at Siying Shipyard, where the vessel is under construction. A launching ceremony for the vessel was held on May 20.Named Caspian Yili, the vessel is the first of its kind in COC's fleet and will be the company's largest vessel to date. The SPA90 design features 90 tonnes of bollard pull, DP2 capability and diesel-electric propulsion.
