In the United States, marine transportation is responsible for $361 billion, or 1.7% of the U.S. Gross Domestic Product (GDP). Marine transportation, a key part of global logistics and responsible for 40% of international trade, goods and services, is the backbone of U.S. trade. In the U.S. in 2021 alone, ships have transported more than 1.5 billion tons of cargo valued at more than $1.5 trillion; in that same time period, U.S. ports have facilitated approximately 450,000 ships, which is more than 10% of the global amount (McLean, 2021).

Moises DelToro at GE Vernova’s Power Conversion business, discusses how deploying a Ship’s Electric Grid is a flexible way to accommodate growing energy demands for naval and coast guard vessels.A new age of electrificationWe’re in a new naval era and it is reshaping views about fleet mixes and capabilities. Modern fleets need to be mission-configurable, highly capable for military advantage, adaptable for technology insertion, but still affordable. The growing demand for vessel power is increasingly an enabler for mission systems, not just for platform propulsion.

WTIVs have always been fuel-hungry. Now they are being tasked with installations that are further, deeper and heavier.Offshore wind farms continue their march into deeper water, further from shore, with turbines that can now reach more than 270 meters high with blades 120 meters long. Designers and OEMs are pushing efficiency to new levels to contain OPEX on the new-generation jack-up WTIVs taking them up there.Danish ship design firm Knud E. Hansen has chosen specialization for its Atlas A-class WTIV, a smaller derivation of its massive C-class design.

Mobile Cable Positioning Devices can quickly accommodate vessels of many sizes and shapes, making shore power available almost immediately, a boon to the industry’s ambitious decarbonization goalsOne of the keys to reaching Cruise Lines International Association’s (CLIA) target of net-zero carbon cruising globally by 2050 is switching from diesel burning engines to shoreside electricity while in port. Although the technology can significantly reduce emissions to address climate change and improve air quality…
