Transcontinental Capital (Bermuda) has awarded a contract for the SCC-800 2x1C SeaFloat barge-mounted floating power plant in the Dominican Republic jointly to Siemens and the marine unit of ST Engineering.
Under the contract, Siemens will provide its combined cycle power plant with a capacity of 145MW, while ST Engineering will provide services in engineering design, procurement and construction (EPC) of the floating power barge and the installation of the floating power plant, which is called as Estrella del Mar III.
Siemens Power and Gas Global Sales CEO Karim Amin said: “Our trendsetting SeaFloat technology combines state-of-the-art combined cycle power plant technology with the mobility and flexibility required by the current and future energy market.
“Our vision is a future with access to affordable but clean electricity and clean water for everyone. A tough challenge to achieve, but a necessity in light of climate change and the need to provide electrical energy for the world’s growing population.”
For this floating power plant, Siemens will also deliver its hybrid SIESTART solution, which is a mix of flexible (gas turbine) combined cycle power plant with a battery energy storage system.
Seaboard Estrella del Mar III will commence its operations in Santo Domingo in 2021.
ST Engineering Marine president Ng Sing Chan said: “This collaboration between ST Engineering and Siemens leverages each other’s strength and capabilities to design, build and deliver a technologically advanced floating power barge.
“We’re excited that in the end, the SCC-800 2×1 floating power plant will bring clean and green electrical energy solution to benefit more people in the Dominican Republic.”
Transcontinental Capital (Bermuda), which is a subsidiary of Seaboard, chose an SCC-800 2×1 SeaFloat concept with two Siemens SGT-800 gas turbines and one SST-600 steam turbine due to constraints in free land and their earlier experience with power barges.
This concept enables the firm to raise its plant size as compared to a land-based power plant.
Furthermore, the gas and steam turbine generation sets are of one lift package design for floating applications and feature an integrated based frame design with a three-point mount.
Fluence Energy, a firm of Siemens and AES, is providing a 5MW/10 MWh battery energy storage system for the SIESTART solution, which will be integrated into the power plant for frequency regulation control. This system also enables the facility to operate at complete capacity with fuel efficiency.
During peak loads or outages, variations of SeaFloat power plants can be used as a base load, or emergency backup for existing power plants. In case of a humanitarian disaster, they can quickly supply power.
