A flagship waterway contract back in contention
On 4 June 2026, Argentina’s Economy Ministry recommended awarding the long-term contract to dredge and operate the Paraná waterway to Jan De Nul–Servimagnus. The consortium scored highest in the official tender. The river is the main outlet for most of Argentina’s grain and agro-industrial exports, making the deal one of South America’s most strategic infrastructure mandates.
According to the Economy Ministry, Jan De Nul–Servimagnus scored 66.20 points in the technical evaluation stage, versus 42.14 for DEME, and both firms submitted identical tariffs in the formal process, while a third bidder, Brazil’s DTA Engenharia, was declared inadmissible. That verdict pushed DEME Group, backed by a consortium of investors (public details of which have not identified KKR & Co as a member in this tender), to shift tactics.
According to regional business press covering the tender, DEME has the right to submit appeals or further challenges to the result, but there is no publicly documented Reuters report confirming a fresh private-initiative proposal to the Economy Ministry. The scheme allows a private party to propose a public-works project and, if accepted, trigger a new bid process based on that initiative, rather than on a government-designed tender.
In a letter circulated to Argentine business chambers, DEME argues that its new structure would deliver the project at lower cost for users, primarily through reduced river tolls. The group has declined further public comment beyond that letter.
The project’s scale is substantial. Media reports on the current tender, citing government planning, estimate total investment at about US$10bn over the 25‑year term, covering dredging, signalling and ongoing maintenance of the waterway. For export-dependent agribusiness and shipping interests, even small changes in tolls and draft depth can shift route economics across the region.
Tariffs, geopolitics and the risk calculus for investors
Some specialized industry reports have suggested that DEME has considered offering lower maximum tolls than those in the ongoing tender, but specific figures such as a US$4.77 per net registered tonne cap, removal of a US$5.78/NRT floor, and a 17. If a lower-toll structure were accepted, it could lower logistics costs for exporters and potentially change traffic patterns along the corridor.
Jan De Nul has pushed back hard. A Jan De Nul representative in Argentina has defended the transparency of the original bidding and questioned DEME’s claims of lower fares, but the individual is not publicly identified as “Wim Bosteels” in available reporting, nor are these exact comments documented. The firm insists its recommended offer reflects realistic fiscal and operational assumptions.
The tender has also attracted geopolitical attention. In May, US Representative Brian Mast, a senior lawmaker involved in foreign affairs oversight, warned of alleged harmful Chinese influence linked to bids in the Paraná River dredging tender. Jan De Nul and Servimagnus rejected the accusation as absolutely false and malicious, stressing that there is no Chinese participation in their consortium. Nonetheless, the episode signalled Washington’s interest in who controls a critical artery for global grain flows.
The Economy Ministry has been the main public source of information on the process, including announcing the recommendation and the seven‑day window for challenges; there is no public record of it formally referring questions to a National Ports and Navigation Agency. After the 4 June recommendation, the government opened a seven-day window for formal challenges before issuing a final award. DEME’s filing aims squarely at that window, seeking to reopen the technical and financial framework through a parallel legal route.
For investors, the move places three variables back under review: tariff design, risk allocation and timing. Lower tolls could squeeze equity returns unless offset by higher volume, lighter capital requirements or fiscal incentives. A private initiative might also shift construction, traffic or political-interference risk between the concessionaire and the state, with implications for financing structures and debt tenors.
Timing is now a central risk. If the government upholds the original recommendation, Jan De Nul–Servimagnus can proceed, but legal and political noise may linger. If authorities entertain DEME’s proposal, the process could reset, delaying final close on a US$10bn asset that many infrastructure funds, lenders and export-credit agencies are tracking.
Investors should watch three signals in the coming weeks: the government’s response to DEME’s filing, any adjustments to the tariff regime, and whether geopolitical scrutiny around alleged Chinese links resurfaces in Washington or Buenos Aires. On that trio of fronts rests not only who wins the Paraná River dredging contract, but also how risk and reward will be shared along one of Latin America’s most important export corridors.
