Swiss marine power company WinGD has introduced its first high-pressure LNG dual-fuel engine, the X-DF-HP, developed specifically for the demanding operating profiles of ultra-large container vessels (ULCVs).Unveiled at Marintec China 2025, the new engine arrives at a pivotal moment for shipowners navigating the energy transition, with the IMO’s Net Zero Framework currently paused and the prospect of regional regulation becoming increasingly fragmented. As a result, interest in LNG-fueled tonnage continues to accelerate.Available in X82 and X92 bore sizes…

Safety management system procedures were not effectively implemented when the Spirit of Tasmania I’s second engineer was seriously injured in a fall during engine maintenance earlier this year, the final report from an Australian Transport Safety Bureau (ATSB) investigation confirmed.The accident occurred during a routine oil change on one of the ship’s main engine turbochargers, while it was berthed in Geelong, Victoria, on March 6.Problems encountered during the work led to the decision to replace the turbocharger’s bearing housing cover plate.

After sustaining extensive damage in a December 2024 fire, the tug Lucinda Smith has returned to the water with a fresh start powered by Mitsubishi S12R-Y3MPTAW-3 Tier 3 engines rated at 1260HP @1600RPM each. The repower was completed by Windward Power with support from Laborde Products, giving the rebuilt vessel renewed strength and reliability.Built in 1975 for the U.S. Navy as YTB-140, the Lucinda Smith has sailed under multiple owners and through several repowers across the country. That long history nearly came to an end with the New Bedford fire, but operator Robert B.

Maritime Partners has repowered the pushboat M/V John Austin, replacing its Cummins QSK38 (1300 hp @ 1800 rpm) with a Mitsubishi S12R-Y3 engine rated at 1260 hp @ 1600 rpm.

Technology group Wärtsilä has introduced its NextDF technology for a third engine, the Wärtsilä 46TS-DF dual-fuel engine. While operating on liquefied natural gas (LNG), the Wärtsilä 46TS-DF engine with NextDF feature reduces methane emissions to less than 1.4 percent of fuel use across all load points, achieving as low as 1.1 percent in a wide load range. This is nearly three times lower than the default methane slip factor of 3.1 percent, specified in the FuelEU Maritime and IMO Lifecycle Guidelines for Otto-cycle four-stroke dual-fuel engines.

Wärtsilä will upgrade the Wärtsilä RT-flex main engines on two bulk carrier vessels owned by Turkey-based Ulusoy Sealines.
