SYM Naval develops and executes ship conversion projects that improve the efficiency, performance and operational capabilities of commercial and passenger vessels. From eco-efficient retrofits to major structural modifications, every project is engineered to meet new regulatory requirements and adapt to evolving operational demands.
Our Technical Office leads the entire process—from concept and engineering studies to coordination with shipyards and classification societies—ensuring certified results, reduced downtime and long-term value for every vessel we convert.
If you are still deciding between upgrading your current vessel or replacing it, we cover that in electric vessel retrofit or newbuild.
For inland waterway fleets, see inland fleet electrification: Blue Propulsion system supply or complete conversion.
Every conversion begins with a tailor-made engineering study. We analyse structural changes, stability, cargo modifications, propulsion improvements and eco-efficient solutions to ensure safe, compliant and cost-effective outcomes.
SYM Naval manages conversion works in shipyards worldwide, coordinating propulsion upgrades, accommodation refits, cargo adjustments and system modernisation with precision and minimal downtime.
We work closely with shipowners, shipyards and classification societies to deliver fully certified conversion projects that extend vessel life, ensure compliance and maximise long-term performance.
SYM Naval converts vessels in service to electric propulsion with Blue Propulsion, its 100% electric propulsion system: it replaces the diesel propulsion and carries out the work at its shipyard.
Before the project is committed, the Technical Office assesses the hull condition, available space and weights, stability, operating profile and charging options, together with class and flag requirements. The battery modules meet IACS standards, and SYM Naval coordinates the technical approval with the classification society and the flag administration.
Conversion extends the service life of a vessel whose hull is in good condition. For owners who prefer to work with their usual shipyard, SYM Naval supplies the complete system instead.
