Two years on, Estrella Del Mar III, a barge-mounted power plant jointly designed and constructed by ST Engineering and Siemens Energy is approaching the finish line of completion as it makes its way to Dominican Republic to provide reliable and clean energy.

The combined cycle power plant with a capacity of 145 megawatts is integrated with an innovative hybrid solution that combines a flexible (gas turbine & steam turbine) combined cycle power plant with a battery energy storage system. The Estrella Del Mar III utilizes wasted energy from the gas turbine’s exhaust, converting this wasted energy into usable clean energy for the plant, this together with the battery improves the plant’s total gross electrical efficiency bringing clean and green electrical energy to benefit the people living in Santo Domingo.

Contracted by Seaboard, ST Engineering was responsible for the engineering design, procurement and construction of a self-supporting barge carrying a technologically advanced power plant. With all other plant equipment supplied by reputable suppliers from factories all over the world, based on the precise design and calculations done by our in-house engineering and design team. The main generating equipment consisting of gas and steam turbines were supplied by Siemens Energy, while the Once Through Steam Generator (OTSG) was supplied by an established supplier from Canada. With the self-supporting barge designed and constructed in ST Engineering’s yard in Singapore, 3D modeling was used extensively to allow the various stakeholders from different parts of the world to collaborate seamlessly together. In addition, the entire steam system was designed, fabricated, tested and installed in compliance with the requirements issued by American Society of Mechanical Engineers (ASME). Claudio Dabelic, Vice President Seaboard Power Management, Inc. shared, “The project was completed in a little over two years. Despite the disruptions caused by the COVID-19 pandemic, the team managed to deliver the project successfully. Estrella Del Mar III sailed after a short dry-docking onboard a heavy lift semi-submersible vessel and it is expected to reach its final destination in Dominican Republic by end April 2021.” Upon reaching Dominican Republic, the plant will undergo hot commissioning of the power generation facility before its final delivery to our customer, Seaboard.
