Wartsila completed 2025 with several important strategic announcements, primarily related to divestitures and partnerships designed to simplify its marine portfolio while improving supply chain resilience.
Wartsila Disposes Automation, Navigation and Control Systems to Solix Group
Wartsila has reached an agreement to sell its Automation, Navigation and Control System (ANCS) business to Swedish investment firm Solix Group AB. ANCS provides marine navigation and automation hardware and software systems such as integrated systems, advanced sensors for safety purposes and dynamic positioning technologies. Acquired through Marine Systems International in 2015, this division produced more than EUR 200 Million in revenue during 2023.
Tamara de Gruyter, President, Portfolio Business and Executive Vice President at Wartsila, commented on this move by noting: ANCS is an industry leader for marine navigation and automation solutions, having worked with Solix on prior divestments I am confident ANCS will have an owner that can drive independent growth to serve customers, partners, and its talented professionals.
The transaction currently awaits regulatory approval and is set to close by Q2 2025.
Transfer of Gas Solutions Business to Mutares SE & Co KGaA
Wartsila announced on 22 December 2025 the sale of its Gas Solutions business to Mutares SE & Co KGaA as part of their portfolio realignment, following on the heels of VINCI Energies purchase of Marine Electrical Systems earlier in 2025. This move further supports Wartsilas ongoing focus on diversification.
Wartsila's divestment of Gas Solutions allows Wartsila to sharpen its focus on marine propulsion and power systems amid industry decarbonization pressures, while expanding core competencies.
Siempelkamp Giesserei Forms Strategic Partnership to Increase Supply Chain Security
On 9 December 2025, Wartsila and Siempelkamp Giesserei joined forces in order to strengthen Wartsilas supply chain for future growth. Through this alliance, Wartsila will gain access to high-quality castings needed for engine manufacturing and marine equipment production.
Wartsilas commitment to safeguarding supply chain vulnerabilities in the maritime sector, where demand for sustainable propulsion solutions has become ever more critical, is demonstrated through this agreement.
Contract Engine Supply Agreement for Brazilian Pusher Tugs
Wartsila earned an order from AMAGGI in Q4 2025 to supply engines for two new pusher tugs being constructed at Beconal Shipyard in Manaus, Brazil for them. Each vessel will feature two Wartsila 20 engines with biodiesel capability as well as the Wartsila Data Collection Unit to deliver 2,100kW total power to move up to 20 barges carrying 32,000 tons of grain through Amazon waterways.
Biodiesel compatibility was instrumental to Wartsila winning this contract, with equipment deliveries planned beginning August 2026. This order builds upon their 30-year partnership, furthering sustainable river transport in Brazil.
Four Key Trends Influencing Shipping Industry 2026
Wartsila identified four trends set to impact global shipping in 2025: lifecycle optimisation, digitalisation with big data analytics, flexible decarbonisation strategies and less predictable regulations. Lifecycle optimisation involves adopting long-term vessel strategies from design through end of life with collaboration among owners, operators and OEMs in mind.
Digital tools enable real-time analytics for fuel and emissions reductions, but data governance challenges persist. Regulation, such as EU ETS and FuelEU Maritime compliance obligations amid delays to IMO Net Zero requirements requires robust compliance; to meet them Roger Holm of Wartsila Marine highlighted collaboration across ecosystem for decarbonisation and digitalization efforts.
Wartsila's developments position it to facilitate maritime transitions toward sustainability and efficiency.
