Floating power plants

Power barges: decentralised power generation

BWSC offers a proven power barge design based on our vast experience in engine-based power plants. A power barge provides a stable, quickly accessible power supply to areas in acute need of electricity.

Where and when to consider a power barge

Power barges are not for every generation application, but can offer certain advantages over land-based plants:

  • Manufacture of the floating barge structure and installation of the generation equipment can be conducted at most shipyards and marine construction facilities.

Advantages: attractive prices, high productivity, regional financing incentives and relatively short lead times.

  • A well designed power barge utilises established technology and is a low-risk mobile asset, easily financed with little or no stranded costs. Once a Power Purchase Agreement (PPA) has terminated, the barge can be removed and relocated to another site.

Advantages: extremely high asset value, minimum impact on local environments and the option to relocate or trade.

  • A power barge can be rapidly delivered and moored in sheltered coastal areas, river estuaries, on existing docks or at a primitive sheet piled wharf, independent of local resources, unsatisfactory infrastructure or poor soil conditions. Barges can also be floated into dredged-out areas and back-filled to form virtual land-based plants that can be removed at some point in the future.

Advantages: fast and stabile power to remote areas and the ability to install despite poor infrastructure or soil conditions. 

Proven track record - updated design

We have delivered a number of power barges, but has recently updated to a standard design, allowing for shorter lead times and competitive pricing. The BWSC power barge is designed to utilise four to eight large- bore engines operating on natural gas or dual fuel (HFO or LFO) with thermal efficiency up to 50% at all loads, including part load.

Standard power plant spacing between engines has been maintained for optimal operation ability and maintenance.
