A battery system may meet certification requirements, but long-term performance depends on factors such as vibration resistance, thermal management, integration design and serviceability. These factors can significantly impact maintenance requirements and operational uptime throughout the vessel lifecycle.

LFP (Lithium Iron Phosphate) and NMC (Nickel Manganese Cobalt) are the two most common lithium-ion battery chemistries used in maritime applications. Each offers different advantages depending on the vessel's operational requirements. LFP batteries are known for their long cycle life, thermal stability and robust safety characteristics. They are often selected for applications where space and weight are less critical, but maximum longevity and durability are priorities. NMC batteries offer significantly higher energy density, meaning more energy can be stored within the same space and weight envelope. This makes NMC particularly attractive for vessels where installation space is limited or where longer operating ranges are required. The right choice depends on the vessel, operational profile and project objectives. Factors such as available installation space, charging opportunities, range requirements, weight constraints and lifecycle expectations should all be considered when selecting a battery system. At TESVOLT OCEAN, we work with both technologies and help operators determine which solution best fits their application rather than applying a one-size-fits-all approach.

Battery sizing depends on vessel type, operational profile, charging opportunities, route length and power demand. TESVOLT OCEAN uses operational data and planning tools such as MERI to help evaluate requirements and support electrification projects.

Retrofit projects often involve space constraints, existing equipment and vessel-specific integration challenges. Flexible installation options, compact system dimensions and modular designs help simplify deployment and reduce project complexity.
