Keppel Offshore & Marine (Keppel O&M) has secured a contract to build an offshore wind turbine installation vessel from US-based energy company Dominion Energy.

As part of the $600m engineering, procurement and construction contract it secured, the vessel is being built by Keppel O&M’s shipyard in the US, Keppel AmFELS.

The company further stated that the vessel is scheduled for delivery in 2023 and will be Jones Act compliant.

To be named Charybdis, the new vessel will be available for charter hire to offshore wind developers to support several of the upcoming offshore wind farms to be built off the US coast.

The vessel is expected to support in installing at least 5GW of offshore wind in the US

By 2027, the vessel is expected to support the installation of 5GW offshore wind projects on the US East Coast.

As per Keppel, the vessel’s hull will have a length of 472ft, a width of 184ft and a depth of 38ft, making it one of the biggest offshore wind installation vessels in the world.

It will feature a main crane with a boom length of 426ft and an expected lifting capacity of 2,200 tonnes. The WTIV is expected to accommodate about 119 people.
