Antin Infrastructure Partners, a French private equity firm, has bought American shipyard Vigor Marine Group from Dallas-based Lone Star Funds for an undisclosed sum.
Antin has vowed to expand capacity across Vigor Marine’s five locations in Seattle, Portland, Vancouver, San Diego and Norfolk. In total, the group operates six drydocks and 29 berths today, employing some 2,700 people.
Ryan Shockley, senior partner at Antin, commented: “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.”
Last year, South Korea’s Samsung Heavy Industries paired with Vigor Marine to modernise its repair yards and expand naval MRO capacity on the US west coast as part of the Trump administration’s plans to revitalise American shipyards.
