One of North America’s busiest ferry routes is joining the growing trend for U.S.-based operators to make the efficiencies of electrification central when they modernize their fleets, after an integrated hybrid-electric propulsion system from ABB was selected for the new ship ordered by Delaware River and Bay Authority (DRBA).Shipbuilder Senesco Marine contracted ABB to deliver full propulsion and automation systems for the 75-car passenger and vehicle ferry, which will replace the 45-year-old Cape Henlopen in connecting Lewes, Delaware and Cape May, New Jersey.

America’s maritime infrastructure is measured in draft depth, vessel clearance, sediment management, and days available to dredge. If the United States is serious about competing in a century defined by supply chains, energy exports, and sealift readiness, then ports, harbors, and waterways must move from being in the background to becoming part of the national strategy.The Dredging industry and it importance to the U.S. Port infrastructure will be discussed in depth at the Port of the Future Conference and Exhibition, scheduled for March 23-25 in Houston.

With a growing focus on mitigating climate change and progressing toward the International Maritime Organization’s (IMO) 2050 net-zero target, the marine sector is under intense pressure to decarbonize. Today, maritime transport emits nearly one billion tons of CO2 annually, representing roughly 2-3% of all energy-related carbon emissions worldwide .Substantial progress has been made over the past decade in reducing emissions from small commercial and coastal vessels via all-electric and diesel-electric propulsion (DEP) systems.

Maritime 2026 opened with a bang between the announcement of Battleships, Venezuela, shadow fleets and yes, U.S. shipbuilding. The commercial building issue may come down to strategic patience or the adaptability to evolve through new technology while ignoring historic, old tactics. The subject requires another year of debate as the line separating the success or failure of Naval and Commercial shipbuilding in the U.S. is slowly becoming a blur. Look towards Naval growth developing in non-traditional patterns … because it has to.With China leading all of the discussions…

In 2010, the Monterey Bay Aquarium Research Institute (MBARI) began the process of replacing its research vessel, R/V Western Flyer. With Glosten at their side as vessel designer, MBARI considered three types of ships for their new project. The Western Flyer was a small waterplane area twin hull (SWATH), but the parties agreed on a monohull design for the new vessel. In 2021, Freire Shipyard won the bid to build the vessel, and R/V David Packard came to life.There is no “I” in TeamWill Moon…
