Mammoet & ULC‑Energy team up

Mammoet and ULC-Energy said on April 14 they signed a cooperation agreement to plan the heavy lifting and transport work needed for new nuclear projects in the Netherlands. (mammoet.com) Mammoet is a Dutch specialist in engineered lifting and oversized transport, and ULC-Energy is a Dutch nuclear developer with offices in Amsterdam and Arnhem. ULC-Energy says it is the project developer for Rolls-Royce Small Modular Reactor in the Netherlands. (mammoet.com) (ulc-energy.com) The companies said the work will focus on modular construction, which means building large sections off-site and moving them into place for installation. Mammoet said that approach can shorten schedules for nuclear plants by shifting more fabrication away from the main site. (mammoet.com) That logistics planning lands as the Netherlands is pushing a broader nuclear buildout. World Nuclear News reported that the Dutch government’s earlier plan called for two new reactors of 1,000 to 1,650 megawatts each around 2035, while later policy documents widened the ambition to four new reactors, including possible small modular reactors. (world-nuclear-news.org) (cnpp.iaea.org) The Dutch government also published a national Small Modular Reactor strategy on October 17, 2025. That strategy said the state was preparing the rules, studies and stakeholder work needed for possible deployment of smaller factory-built reactors. (rijksoverheid.nl) The immediate problem these companies are trying to solve is not reactor physics but construction bottlenecks. Nuclear projects depend on moving very large components on tight schedules, and delays in transport, crane work or site access can push back the rest of the build. (breakbulk.com) (mammoet.com) Mammoet has been building out this position in Dutch nuclear work for months. In November 2025, it signed a separate memorandum of understanding with Electricité de France to improve construction methods for upcoming nuclear facilities in the Netherlands. (niauk.org) ULC-Energy, for its part, has been trying to line up demand as well as technology. In November 2025, Equinix said it was working with ULC-Energy to explore up to 250 megawatts of small modular reactor capacity for Dutch data centers. (esg-investing.com) The Dutch supply-chain push is already being quantified. A report highlighted by World Nuclear News this month said businesses in Zeeland could capture as much as EUR 4.6 billion in direct economic value during a 12-year construction period if new reactors are built there. (world-nuclear-news.org) For now, the Mammoet-ULC deal does not announce a final reactor order, site award or construction start. It does show Dutch nuclear developers and contractors moving earlier into the practical work of how to get giant components to a site and assembled on time. (mammoet.com) (world-nuclear-news.org)
