Offshore

Vessels far from shore must withstand harsh conditions

Offshore operations such as oil and gas platforms, offshore wind service vessels, and support ships often work far from shore. Reliability is critical since an unexpected failure can delay operations and become very costly. Safety is also a top priority because personnel operate in remote areas where evacuation can be difficult. Power systems must handle rough seas, vibration, exposure to saltwater, and a wide range of temperatures.

Big challenges require smaller solutions

Battery systems in offshore applications face several challenges. They may need to supply large amounts of power for short bursts, for example during dynamic positioning or crane operations, and then recharge quickly when generators are running. They must cycle frequently and maintain performance for years, since replacement offshore is both expensive and difficult. Safety is crucial, as fire or thermal runaway at sea can have catastrophic consequences. Systems must also be compact and easy to integrate with hybrid propulsion or platform power grids.

Battery systems you can trust

Echandia’s LTO battery systems deliver very high power instantly, withstand many thousands of deep cycles without significant capacity loss, and recharge quickly when power is available. The LTO chemistry is inherently safe and thermally stable, reducing fire risk and simplifying safety systems. It performs reliably in both cold and hot climates and tolerates partial charging, making it perfectly suited for the varied and demanding conditions of offshore operations.

Why Echandia for offshore vessels:

  • PROVEN RELIABILITY
    Stable performance under rough sea conditions

  • HIGH POWER OUTPUT
    Supports dynamic positioning and heavy lifting operations

  • FAST CHARGING
    Efficient recharging during generator operation

  • CLASS-LEADING SAFETY
    No thermal runaway, no fire risk

  • COMPACT INTEGRATION
    Ideal for hybrid propulsion and platform power systems

Advanced energy storage for European defense applications

Echandia is delivering advanced energy storage systems for six naval frigates commissioned by European NATO member countries. The orders include an initial contract for four vessels, followed by an additional order for two more, confirming Echandia’s position as a trusted long-term partner in the electrification of the maritime defense sector.

Hybrid RoPax retrofit with Echandia LTO systems

Scandlines, one of Northern Europe’s leading ferry operators, has taken a major step toward zero-emission operation by converting two of its RoPax ferries into plug-in hybrids. The vessels are being retrofitted with Echandia ERS3 LTO battery systems, enabling up to 80% electric operation per crossing, with diesel propulsion retained only as backup.

Fully electric RoPax ferry Nerthus

In June 2025, Molslinjen introduced Nerthus, a fully electric RoPax ferry serving the route between Ballen on Samsø and Kalundborg in Denmark. The vessel is the first of two new electrified ferries commissioned by Molslinjen and built at Cemre Shipyard in Turkey.
