High-power battery systems for frequent, intense operations

Tugs and workboats perform short but demanding tasks such as towing, pushing, harbor maneuvers, and offshore support, often at irregular times and intensity. They need to deliver instant power for bollard pulls, firefighting, or dynamic positioning, and then recharge quickly between jobs.

Battery systems must handle very high power output for short bursts while accepting high charging power from onboard generators or shore connections without degrading quickly. They often cycle many times per day and must keep performing for years with minimal maintenance.

Reliability is critical

Operating environments are harsh, with constant vibration, saltwater spray, and exposure to both heat and cold. Reliability is critical since any breakdown can delay port operations or offshore work, creating costly downtime for operators and customers. Safety is equally important because engine rooms are compact and a fire onboard could be extremely dangerous.

A perfect fit for tugs

Echandia’s LTO battery systems deliver high current safely and rapid recharge, making them ideal for tugs that need to be ready for the next job with minimal downtime. The systems’ long cycle life means fewer replacements and lower lifetime cost. The chemistry is highly stable, minimizing fire risk and ensuring reliable performance even in extreme temperatures.
