Hybrid Power

A hybrid system allows for entirely emission-free periods and greatly contributes to running more sustainable marine operations and lower operational costs. 

The holistic approach to vessel integration ensures the system works seamlessly with the ship's existing power systems.

Battery powered hybrid solutions

The Ulstein Hybrid Power Solution introduces a new element integrated into a ship's main power system where the added 'grid support functions' give new opportunities for flexible vessel operation. The system solution contains battery energy storage, power conversion and energy management as the main elements.

The holistic approach to vessel integration ensures the system works seamlessly with the ship's existing power systems.

Benefits with hybrid power

Improved energy efficiency
Reduced fuel consumption
Reduced emissions, also emission-free in some operations
Less wear and tear
Peak shaving for best operational results
Reduced operational expenditure

Strategic loading

Ulstein's hybrid solution enables the crew to manage engine load fluctuations and extend the use of battery power. A strategic schedule controls when the combustion engines are started and stopped and the batteries are charged or discharged accordingly. The hybrid setup saves fuel, energy, cost and the environment.

Zero-emission mode

In zero-emission mode, the vessel is powered exclusively by the energy storage system. One major benefit is a cut in local emissions. The zero-emission mode functionality can be scaled from minutes of operation in harbour, to operations of vessels with predictable schedules in terms of activity and energy.

Smart DP operations

When power demand fluctuates, combustion engines may not be operating efficiently. With hybrid solutions, this is a problem that’s easily avoidable. The hybrid power system increases efficiency, handling the peak loads by smoothing the load of the engines. This process prevents unnecessary start-up of standby engines, improving overall vessel efficiency.

Spinning reserve symbol imgtxt

Spinning reserve

For operations requiring redundancy on power supply such as DP operations, more combustion engines need to be running than strictly required to support power demand. In these cases the hybrid power system can act as a source of spinning reserve energy, enabling the vessel to operate safely with fewer engines running.

How we work on hybrid-powered vessel projects

We can assist you throughout a shipbuilding project. We offer complete follow-up, starting with the design and engineering phases, through site support, pre-/commissioning and testing before delivery, and aftermarket services after the vessel has entered operations.

Holistic approach - suited for customer needs

We base our solutions on multidisciplinary teams, ensuring our customers get the professional support needed in each case.

Multi-disciplinary effort

With assistance from our dedicated experts, a multi-disciplinary effort secures delivery and quality for our customers. 

Our multidisciplinary teams consist of the following:

  • Project management
    • Planning
    • Business Analysis
  • Naval architecture
    • Arrangements
    • Hydrodynamics
    • Stability
  • System architecture
    • Electrical systems
    • Machinery systems
  • Structural engineering

Operational analysis

Another part of our holistic approach is planning and analysing customer needs and uses in hybrid energy solutions. In addition, we help with operational analysis. This ensures the vessels operating on our solutions are using them in the most efficient way possible.

Some aspects of operational analysis are:

  • Identify and define the energy storage system
  • Planning the physical integration
  • Define system capacities
  • Estimate fuel savings and emission reductions

Project execution

  • Planning and set-up
  • Retrofit or new vessel installations
  • Installation support
  • Site support
  • Pre-commissioning
  • Commissioning
  • Services and upgrades

Retrofits and upgrades

Life cycle assessments

Life cycle assessment estimates the environmental impacts of all stages in the vessel's life.

We continually work to provide the power systems with greater capability, higher productivity and enhanced quality of vessel performance. These improvements are offered on new solutions, as well as retrofits, conversions and upgrades of existing systems.
