Battery hybrid

Battery-powered propulsion reduces fuel consumption and emissions. Depending on setup and operational profile of the vessel, the CO2 reduction will be in the area of 10-30%. The hybrid system also allows for completely emission-free periods.

The battery hybrid solution reduced wear and tear of the engines. With batteries, the ship’s crew will be enabled to manage the load fluctuations placed on the engine and run the engine more smoothly.

Ulstein’s battery energy storage system (BESS) is suitable for a range of vessels and operations.

The system is scalable in terms of energy and power and can be integrated with a variety of power systems. Standardized components ensure scalability with no compromises on functions or quality.

Reduced emissions and engine load

Zero emission mode
An option for vessels that frequently enter harbours. The vessel is powered solely by the BESS. The benefits are a cut in local emissions. This function-ality can be scaled from minutes of operation in harbour, to operations of vessels with very predictable opera-tions in terms of activity and energy.

Strategic loading
Vessels sailing long distances are not able to sail on batteries only. For these vessels, the battery enables the crew to manage the load fluctuations on the engine. The combustion engines are started and stopped according to a strategic schedule, where the BESS is charged and discharged accordingly.


Smart DP operations

Spinning reserve
For operations requiring redundancy on power supply, such as DP opera-tions, more combustion engines need to be running than strictly required to support the power demand.
The BESS can act as a source of spinning reserve energy, enabling the vessel to operate safely with fewer engines running.

Peak shaving
When power demand is fluctuating, combustion engines may not be oper-ating efficiently.
The BESS effectively handles the peak loads by smoothing the load of the combustion engines, and thus leads to avoid the unnecessary start-up of standby engines.

RETROFITS & UPGRADES

LIFE CYCLE ASSESSMENTS

Life cycle assessment is defined as a technique to estimate the environmen-tal impacts of all the stages in the life of the product, in our case vessels.
With the BESS, we continually work to provide greater capability, higher productivity and enhanced
quality of the vessels’ performance. These improvements are offered on new solutions, as well as retrofits, conversions and upgrades of existing systems.
