Dominion Energy reported spiralling costs and delays for the Charybdis, the first US-made wind turbine installation vessel (WTIV) under construction in Galveston, Texas.

In its second quarter filing this month with the US Securities and Exchange Commission, the Virginia-based utility noted that costs for the vessel being constructed by Keppel AmFELS have risen to $625m, a sharp uptick from its reported $500m price tag in 2020 when it was commissioned.
