Designed for high efficiency: powerships provide extra generating capacity around the world


Powerships provide electricity when and where it is required, offering flexibility unmatched by land-based power plants. ABB supplies generators for the ships and offers a full range of maintenance services to ensure a steady flow of power.



Powerships operated by Karadeniz Powership Company are generally deployed to a location for two to five years, supplying power where there is an urgent need for extra generating capacity. Each powership is equipped with a number of diesel or gas powered gensets. The vessels in the Karadeniz fleet currently have generating capacities ranging from 45 to 250 MW. The engines either run on HFO (heavy fuel oil) or are dual-fuel designs. Some of the ships are also equipped with steam turbines which are powered by steam produced from waste heat.

Since 2009 ABB has supplied 160 high voltage synchronous generators for the gensets on Karadeniz powerships. The generators are designed for high efficiency, with losses minimized through the effective use of materials, advanced insulation and optimization of key components.The brushless, open ventilated units in frame size 1600 are regular power plant generators that have been custom fitted for shipboard installation. ABB also offers a separate marine generator range, with products specifically designed to meet vessels’ onboard power needs.

It is vital that power plants deliver high reliability, and maintenance has to be available at short notice in case of any failures. With local service centers backed by a global organization, ABB’s support network can supply a full range of services for generating equipment – no matter where it is located. Fast response translates into minimum downtime and maximum power production. ABB also has manufacturing plants located in different parts of the world, providing a global manufacturing footprint that has proved very beneficial for powership projects with short delivery times.
