Tidewater has completed its $500 million acquisition of Wilson Sons Ultratug Offshore, closing a deal that adds 22 platform supply vessels and significantly expands the company’s position in Brazil. The acquired business includes Wilson, Sons Ultratug Participações S.A. and Atlantic Offshore Services S.A., with the transaction effective August 31, 2026. Tidewater said the WSUT fleet is made up of PSVs, most of them Brazilian-built, and the closing gives the Houston-based offshore vessel owner a larger operating base in one of the world’s most active deepwater offshore markets. The company paid about $283.1 million in cash at closing and acquired the target companies subject to about $229.3 million of existing debt provided by BNDES and Banco do Brasil.

Operator Impact Snapshot
Tidewater’s Brazil position changes from limited presence to meaningful PSV scale.
22 PSVs added
The completed acquisition brings Tidewater a full platform supply vessel fleet already tied to Brazilian offshore work.
Brazil fleet expands to 28
The deal lifts Tidewater’s Brazil presence from six vessels to 28, giving it a much larger operating base in-country.
Local tonnage advantage
Nineteen of the acquired PSVs are Brazilian-built, an important factor in tenders and vessel-priority rules in Brazil.
Backlog comes with upside
Earlier deal materials pointed to about $441 million of backlog, with rollover opportunity as older contracts reset toward market rates.
Integration runs into 2027
Management has indicated that full WSUT integration is expected by early 2027, making execution a near-term operating focus.
Debt and guarantees remain visible
The closing included assumed debt and a requirement to replace certain BNDES parent-company guarantees by the end of 2026.

Fleet, Backlog, Local Tonnage and Financing
The acquisition gives Tidewater more vessels, more local status and more exposure to Brazil’s offshore cycle.
Purchase price on a debt-free, cash-free basis, subject to customary post-closing adjustment.
Tidewater also acquired the target companies subject to existing BNDES and Banco do Brasil debt.
The WSUT fleet consists of platform supply vessels, most of which were already active in Brazil when the deal was announced.
The local-built fleet is central to tender access, operating priority and REB capacity.
| Deal Piece | Latest Detail | Commercial Reading | Stakeholder Effect | Signal Meter |
|---|---|---|---|---|
| ClosingEffective August 31, 2026 | Tidewater completed the acquisition of WSUT and Atlantic Offshore Services. | The deal has moved from announced transaction to operating reality. | Customers, suppliers and crews now move into integration, contract management and operating alignment. | High |
| Fleet Addition22 platform supply vessels | The acquired fleet materially increases Tidewater’s PSV base in Brazil. | Scale matters in Brazil because Petrobras and major offshore clients need reliable multi-vessel coverage. | Competitors face a larger Tidewater in PSV tenders, vessel substitutions and long-term service packages. | Severe |
| Brazil Position6 vessels to 28 vessels | Tidewater’s in-country vessel count expands sharply. | The company gains a broader platform for crewing, maintenance, procurement, customer coverage and port logistics. | Suppliers may see more centralized purchasing and stronger demand for Brazilian operating support. | High |
| Brazilian-Built Tonnage19 PSVs | The fleet includes 19 Brazilian-built vessels, which receive priority to operate in Brazil. | Local tonnage status is one of the most important parts of the transaction. | Tidewater gains a stronger position in local-content-sensitive tenders and vessel replacement work. | Severe |
| REB CapacityForeign-vessel optionality | Brazilian-built vessels can support REB capacity for bringing international-flagged vessels into Brazil. | This can turn local vessels into a gateway for broader fleet deployment. | Tidewater may be able to move suitable international tonnage into Brazil with stronger commercial protection. | High |
| BacklogAbout $441M disclosed earlier | The acquired fleet came with significant existing contract backlog. | Backlog lowers immediate utilization risk while contract rollover can create earnings upside if day rates rise. | Customers may face stronger renewal pricing if current market rates exceed legacy contract levels. | High |
| Debt StructureBNDES and Banco do Brasil | Tidewater assumed about $229.3 million of existing debt at closing. | Low-cost, long-duration local debt was part of the transaction economics. | The deal also leaves guarantee replacement and Brazilian lender obligations as execution items. | Medium High |
| Petrobras Demand ContextE&P and fleet renewal | Petrobras plans major E&P investment, new production systems and 40 new offshore support vessels for E&P fleet renewal. | Brazil’s offshore program creates a strong demand backdrop for PSVs, RSVs, AHTS vessels and subsea-support tonnage. | Owners with local vessels, crewing, safety systems and maintenance scale may be better placed in tenders. | High |
