TotalEnergies Marketing Middle East, a fully owned subsidiary of TotalEnergies based in Dubai, has time chartered a first-of-its-type 750 cubic meter hybrid lubricants bunkering barge from Tristar Group to supplement its Lubmarine division’s ship-to-ship operations in the port of Fujairah, UAE as of October 1st. The Tristar Eco Voyager, featuring a hybrid engine design that combines electric and biofuel power, coupled with an advanced powertrain, is designed to significantly reduce carbon emissions compared to traditional diesel propulsion barges.

A new generation of hybrid vessels is demonstrating significant gains in both fuel economy and operational output. For Olympic Subsea’s owner and CEO Stig Remøy, it proves that technology-led efficiency is the fastest path to decarbonization—and a powerful business case.When Stig Remøy began pivoting Olympic Subsea toward subsea and renewables a decade ago, the move was met with some internal skepticism. “Naturally, there were internal discussions — some believed oil and gas was the future,” he recalled.

Damen Shipyards Group unveiled the latest platform in its cargo vessels portfolio: the Combi Freighter (CF) 5000 ICE, the first in a new series of ice class cargo vessels.“Our aim has been to leverage the experience and the success we’ve enjoyed with our next generation cargo vessels to create a platform capable of economic ice navigation," said Remko Bouma, Commercial Director of Damen Cargo Vessels. "The CF 5000 is equally at home in open water and in ice, maintaining both the optimal cargo capacity and high efficiency of the conventional vessel.

Concordia Damen has received a new contract from Reederei Deymann, one of Germany’s largest inland shipping companies, for the extensive refit of a dry cargo vessel Hirschhorn. The vessel recently arrived at the Concordia Damen yard in Werkendam, where the transformation project has now started. The refit involves the complete renewal of the aft ship. Originally equipped with a single engine, single propeller shaft and an outdated living and wheelhouse arrangement, the vessel will undergo a transformation at Concordia Damen’s yard in Werkendam.

No civilian maritime nuclear facilities have been commissioned in over four decades, but there’s been three major reports released this month on their future potential.DNV’s latest report, Maritime nuclear propulsion: Technologies, commercial viability, and regulatory challenges for nuclear-powered vessels, provides a regulatory perspective on security, one of the key challenges for future adoption. As it says: Safety, security and non-proliferation remain paramount. Future installations must be designed to withstand collisions, groundings, and external threats such as sabotage or piracy.

In Memoriam: Captain Charles Robert MacVean, USN, (Ret.), PhDMarch 22, 1937 – September 10, 2025The book, Blind Man’s Bluff, describes the secret USN submarine operations known as “The Projects.” It begins with the opening line, “There was something about Commander Charles R. MacVean that had a way of inspiring legend.” Authors Sontag and Drew narrowed that “something” down to “his sense of humor and humanity.”  Even in the toughest of situations, MacVean radiated calm assurance and situational command.

Interest in hybrid government and patrol boats is growing as boat builders demonstrate their many benefits.Launched last year at Seawork, Sweden-based Marell Boats says its M17 Patrol was the star of the show with its hybrid powertrain from Scania and propulsion system by Marine Jet Power.Like others in the patrol boat market, Project Manager Mario Celegin is seeing increasing interest in hybrid patrol boats. There’s a lot of reasons why: near-silent patrolling in electric mode…
