Antin Infrastructure Partners is acquiring US ship repair and marine services firm Vigor Marine from Lone Star Funds for an undisclosed sum.

Antin said the Vigor Marine deal is the seventh for its fifth infrastructure fund, which focuses on long-term investments in established infrastructure companies in North America and Europe.

Based in Portland, Oregon, Vigor Marine operates shipyard and fabrication facilities across Seattle, Portland, Vancouver, San Diego and Norfolk, with six drydocks and 29 berths serving government and commercial clients.

Ryan Shockley, senior partner at Antin, said: ”We’re thrilled to be partnering with Vigor Marine Group, which represents exactly the kind of long-term investment we pursue – essential US infrastructure assets that require sustained capital commitment and operational continuity.

“We’re focused on expanding capacity, accelerating innovation and supporting workforce development so these shipyards can continue to serve their customers reliably over the long-term. We look forward to working closely with Francesco and the US-based leadership team as they continue to lead the business and execute Vigor Marine Group’s strategy.”

Francesco Valente, CEO of Vigor Marine, said: ”As a dedicated infrastructure investor, Antin is an excellent partner for our continued evolution as a leading repair, maintenance and modernisation provider in the US.

“Antin takes a disciplined, long-term approach to investing in facilities, technology and workforce development to ensure operational continuity and resilience. This partnership provides the added resources we need to take the next step in our long-term strategy and comes as our US-based leadership team remains fully focused on operating our business and serving our customers.”
