In a major step toward sustainable shipping, Dutch solar energy innovator Wattlab has delivered a seaworthy solar power system for Vertom, a global player in shipping, trading, and maritime services. Installed on the MV Vertom Tula, a 7,280 dwt diesel-electric multipurpose cargo vessel, the system features 44 Solar Flatracks providing 79 kWp of installed solar power. This innovation reduces the ship’s hotel load by 20%, marking the world’s first seagoing vessel to be fully equipped with such solar capacity.
Fast Installation and Practical Design
After three years of pilot testing, Vertom decided to fully integrate Wattlab’s solar technology into its newbuild vessel. The Solar Flatracks were produced and assembled in Wattlab’s new Rotterdam facility and installed in a single day at the Port of Harlingen using container twist lock fittings—a system that allows quick mounting and removal.
Co-funded by the EU’s Just Transition Fund (JTF), the project represents a scalable and easily deployable energy solution for coastal and short-sea vessels.
Proven Performance and Crew Acceptance
Vertom’s pilots and TNO’s independent research confirmed the system’s high performance in tough coastal environments. According to Vertom’s Business Development Manager, Thomas van Meerkerk, the technology demonstrated a clear return on investment (ROI) and tangible CO₂ reduction benefits.
Initially, crew members were cautious about added workload, but they quickly adapted, finding the Solar Flatracks easy to maintain and operate. The design prevents salt crust buildup and allows water to drain freely, making them ideal for maritime conditions.
The project has also gained recognition, earning nominations for the IBJ Environmental Protection Award and Bulk Ship of the Year Award.
A Milestone for Maritime Decarbonisation
The MV Vertom Tula project marks a significant advancement in maritime decarbonisation strategies. With new regulations such as FuelEU Maritime and EU ETS driving cleaner operations, Wattlab’s scalable solar systems provide shipowners with a practical means to diversify onboard energy sources.
This development aligns with Vertom’s commitment to sustainability in the Short Sea Shipping sector, enabling reduced fuel consumption, lower emissions, and improved operational efficiency without sacrificing cargo flexibility.
Wattlab’s partnership with Vertom has set a new benchmark in renewable maritime technology, proving that solar power can play a vital role in the energy transition at sea. As the first vessel of its kind to integrate large-scale solar generation, MV Vertom Tula demonstrates that innovation, efficiency, and environmental responsibility can coexist in modern shipping. This success paves the way for broader adoption of solar technology across the maritime sector, offering a cleaner and more resilient future for coastal shipping.
