Kalypso and Royal IHC to Build First Jones Act-Compliant Offshore Wind Cable Layer

Emerging U.S. offshore wind contractor, Kalypso Offshore Energy, has signed a Letter of Intent (LOI) with maritime technology leader, Royal IHC, to construct the first Jones Act-compliant Cable Lay Vessel (CLV) to support the offshore wind sector in the U.S.

The partnership between Royal IHC and Kalypso aims to advance the U.S. wind supply chain by domestically with the production of a 5,000-ton Cable Laying Vessel (CLV), filling a significant gap in the country’s vessel capabilities. The vessel is expected to be available from 2028.

Kalypso’s Cable Laying Vessel (CLV) will comply with the Jones Act, offering versatile cable lay services including installation, repair, and maintenance.

“Kalypso is thrilled to partner with Royal IHC to design and deliver America’s first Cable Lay Vessel built on U.S. soil dedicated to offshore wind,” said Colin Smith, Managing Director of Kalypso, “Kalypso’s CLV will enhance the nation’s offshore energy prospects and foster local economic growth.”

The partnership marks a significant milestone in Kalypso’s mission to offer a local, experienced cable laying solution to the U.S. offshore wind industry.

Kalypso and Royal IHC will continue their close collaboration to finalize the contract, engineering, and construction details.

“I take pride in leading a company capable of delivering this key contribution to the energy transition and energy security in America’s home market. The development of this CLV is a significant milestone for Royal IHC and the offshore wind sector in the U.S. We feel privileged to provide our added value to a knowledgeable pioneer such as Kalypso,” said Derk te Bokkel, CEO of Royal IHC.
