3 We consider equity participation and co-owner status relating to projects built and operated by for our customers and partnersBWSC is dedicated to meeting our contractual obligations in terms of timely delivery, technical performance and environmental compliance of our power plant and barge projects. We have supplied more than 182 power plants to 53 countries with a total generating capacity of more than 3500 MW. In the delivery of Floating power plants , we are committed to partnering with experienced high-quality marine engineering companies to ensure a Class Approved Floating structure together with main equipment manufacturers providing the most advanced generation technologies available.

4 This to ensure proven efficiency and environmental compliance in a low-risk and reusable asset. BWSC YOUR GLOBAL ENERGY PARTNER3 Floating DIESEL power PLANTS3 Floating power plants or power barges are the same tried and tested , modular generating equipment, power house, auxiliary systems and electrical export options normally associated with traditional land-based diesel power plants . Guaranteed performance figures, output, heat rates, etc, and long-term maintenance costs are basically the same.

5 Instead of a turnkey EPC package built onto engineered, piled, reinforced, heavy concrete foundations, dictated by local soil conditions and land prices, the complete power plant package is mounted on a pre-engineered, heavy steel, rigid Floating box. The barge is designed and constructed to Marine Classification Standards and delivered to the selected site by ocean tow or heavy lift ship. Where and when to consider a power bargePower barges are not for every generation application, but can offer certain advantages over land-based plants : Manufacture of the Floating box structure and installation of the generation equipment can be conducted at most shipyards and marine construction facilities.

6 The advantages are attractive prices, high productivity, regional financing incentives, and relatively short lead times. A well designed power barge, utilising established technology, 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, ensuring an extremely high asset value and minimum impact on local environments. 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.

7 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.
