Tidewater (NYSE:TDW), the world’s largest owner of offshore support vessels, announced a definitive agreement on Sunday to acquire Wilson Sons Ultratug Participações and its affiliate Atlantic Offshore Services(collectively “WSUT”) in a deal valued at $500 million.
The move signals a massive bet on Brazil’s offshore energy sector, transforming Tidewater into a dominant player in one of the world's most lucrative maritime markets.
The all-cash transaction includes the assumption of approximately $261 million in existing debt, which Tidewater plans to roll over to preserve attractive, long-duration financing terms provided by Brazil’s BNDES and Banco do Brasil.
By acquiring WSUT’s fleet of 22 platform supply vessels (PSVs), Tidewater will expand its Brazilian footprint nearly fivefold—from six vessels to 28.
On a pro forma basis, the deal brings Tidewater’s global fleet to 231 vessels, including 213 offshore support vessels (OSVs).
The strategic prize of the acquisition lies in the "local content" status of the fleet; 19 of the 22 vessels were built in Brazil.
Under Brazilian maritime law, these vessels receive priority in commercial tenders and provide Tidewater with Brazilian Special Registry (REB) tonnage rights, a regulatory advantage that allows the company to import and operate international-flagged vessels with the same preferential status as local tonnage.
