Jan De Nul Rebuts Competitor’s 17.4% Tariff Cut Claim in Hidrovía Tender

The preadjudicated bidder says DEME omitted VAT, understated required investments, and overstated future tolls, making the proposed 17.4% discount unsustainable.

La concesión de la Hidrovía entró en su etapa decisiva con fuertes cruces entre las empresas.

Overview

  • The Jan De Nul‑Servimagnus consortium, which ANPYN recommended and the Economy Ministry named preadjudicatario, sent a letter on June 12 to agribusiness leaders contesting a DEME claim of a 17.4% tariff cut.
  • Jan De Nul says DEME’s financial model counts only about US$95 million of VAT over 25 years while a consistent calculation would be roughly US$1,600 million, which would remove the margin that enables the proposed discount.
  • The consortium also charges that DEME plans only US$280 million of investment in the first five years and none thereafter, versus more than US$850 million in the UNCTAD model and Jan De Nul’s offer, a gap that would undermine long‑term maintenance and modernization of the waterway.
  • Jan De Nul argues DEME overstated post‑dredging toll revenue by about US$370 million by modelling fees above the contract maximum, and it notes DEME previously endorsed the tender rules in November 2025 and did not raise these objections during the formal process.
  • The exchange is a technical, public contest between bidders intended for exporters and policymakers; the preadjudication in favor of Jan De Nul‑Servimagnus remains reported and no formal administrative reversal or court ruling has been published.
