Seaboard Marine Integrates LNG-Fueled Containerships into Fleet
Miami-based carrier Seaboard Marine is advancing its operations by integrating a new class of LNG-fueled containerships into its fleet serving South America. The carrier introduced the first two vessels of its innovative V-Class, with a total of six ships scheduled to join the fleet by the end of 2025.

This marks a significant step in the adoption of LNG technology, praised for its environmental benefits and fuel efficiency. Seaboard Marine joins other U.S. carriers like TOTE, Pasha, and Matson, which have been at the forefront of deploying LNG-fueled ships. Notably, TOTE launched the first such vessel in 2018, and others continue expanding their LNG capabilities with new builds and conversions.
Designed by HB Hunte Engineering of Germany, Seaboard Marine’s new vessels are being constructed by China’s Taizhou Sanfu Ship Engineering Company. Initially ordered in 2022, the series was expanded in 2023, bringing the total to six ships. These vessels are the largest containerships built by the shipyard to date.
Among the standout features of the V-Class are the double C-type vertical gas tanks, which are the largest of their kind globally. The ships also boast an innovative bow design, enhancing efficiency. Powered by dual-fuel MAN B&W 7570ME-C10 engines, the vessels can operate on LNG or marine gas oil (MGO), supported by two diesel generators and one LNG generator. Classed by DNV, the ships are designed for a speed of 19.5 knots.
Eddie Gonzalez, President and CEO of Seaboard Marine, highlighted the significance of the milestone, stating, “The Seaboard Victory marks an exciting step in our sustainability journey and our commitment to providing exceptional service to customers.” This vessel, the second in the V-Class, recently made its inaugural stops in Callao and Pisco, Peru, joining its predecessor Seaboard Voyager, which began service in November.
Each V-Class vessel offers a capacity of 3,500 TEU, including over 1,000 reefer plugs, and a deadweight of 52,500 dwt. These ships, flagged in Liberia, operate on routes connecting the U.S., the Caribbean, and Central and South America.
Seaboard Marine’s shift to LNG began in 2023 with the acquisition of the Elbblue, retrofitted in 2017 for LNG and renamed Seaboard Blue. This vessel, with a capacity of 1,000 TEU, was the first LNG-powered containership to bunker at PortMiami before its maiden voyage to Honduras and Guatemala.
By the end of 2025, Seaboard Marine’s LNG-powered fleet will comprise eight vessels, underscoring the growing trend in the shipping industry. According to DNV’s Alternative Fuels Insight database, LNG-fueled containerships represent the largest segment of LNG-powered vessels, with 127 currently in service and 314 on order. By 2028, the number is expected to surpass 400, signaling a significant transformation in maritime operations.
