The US is going to need an estimated $22.4bn in offshore wind investment in the next seven years, but vessels are only a portion of it.

Of the total investment, roughly $3.75bn will be needed for large ships such as wind turbine installation vessels (WTIVs), heavylift ships and barges to meet the White House’s goal of producing 30 GW of offshore energy by 2030, according to figures from the National Renewable Energy Lab (NREL) included in an Evercore note following the Floating Wind Solutions Conference & Exhibition in Houston, Texas.
