SeaFloat power plants

Are you looking for a highly efficient combined cycle power plant but are limited in space or simply need mobile energy supply? Or do you want to replace one of your old assets with a highly efficient combined cycle power plant but you are facing high soil risks or brown field risks? Do you need a robust simple cycle power plant that will cover peak loads under tough conditions?

The SeaFloat power plants range provides a choice of different sizes of combined cycle based on aeroderivates (e.g. SGT-A35), mid-sized industrial gas turbines (e.g. SGT- 750, SGT-800) and heavy duty gas turbines (e.g. SGT-8000H). Optimized to the project specific requirements in power output, efficiency and load regime all applications can be installed on different types of floating devices such as a simple barge, typical platform (e.g. oil & gas platforms), floating production and offloading unit (FPSO) or Floating Storage Regasification and Power Unit (FSRPU). SeaFloat is the highest form of modularization providing power plants in one piece as a mobile asset or for a permanent installation. With focus on the Oil & Gas business SeaFloat makes fossil greener by utilization of the offshore combined cycle solutions to reduce fuel consumption and greenhouse gas emissions.

The SGT-800 combines a simple, robust design, for high reliability and easy maintenance, with high efficiency and low emissions. With more than 340 units sold and over 6 million equivalent operating hours, the SGT-800 is an excellent choice for industrial or oil and gas applications. 

The SST-600 is a steam turbine designed for operation within speed ranges of 3,000 to 18,000 rpm for generators or mechanical drives up to 200 MW. More that 400 units operating worldwide and have produced more than 16 GW electricity in more than 16.3 million operating hours.

SeaFloat power plants equipped with world-class efficient SGT-800 in combined cycle application are available in configurations for 150 MW up to 450 MW.

Operational flexibility based on actual operational requirements provides a wide field of applications in industrial environments as well as for baseload operation in remote areas. All gas and steam turbine packages are system-tested with dedicated electrical and control modules prior to shipment.

Continuous evolutionary optimizations, advanced remote diagnostic algorithms and forecasting of component life lead to world class reliability.

The SGT5-8000H offers outstanding performance and high flexibility. With a gross power output of 450 MW and a quick ramp-up from start to full load, the turbine offers low lifecycle costs and helps to meet fluctuating power demands.

Even Siemens’ high end SGT-8000H gas turbine is available as SeaFloat application, in 1x1 as well as 2x1 combined cycle configurations. It delivers up to 1,330 MW with a plant efficiency of more than 61%, mainly focusing on the substitution of older plants such as nuclear power plants and coal fired power plants.

The SeaFloat ULCC (Ultra Light Combined Cycle) is designed for offshore application with compact footprint and low weight. It is our response to reduce carbon footprint in offshore projects. Up to 110.000t CO2 can be reduced per annum on one FPSO (Floating Production storage and offloading Unit) and is comparable to the emissions of a European City with 17.000 inhabitants. Under consideration of CO2-taxes it provides a significant economic savings.
With a modular design for fast and easy installation, the ULCC can be profited as an offshore single lift package in a plug & play concept. It provides maximum operational flexibility providing heat and power with a total efficiency of up to 70%. The design of the water-/steam cycle has been considered carefully with lowest possible complexity but with highest operational flexibility. The smart heat extraction allows flexibility in balancing heat and power provision.

The SeaFloat concept uses Siemens Energies proven equipment and reliable technology and optimizes these solutions for a floating application. All open cycle and combined cycle power plants can be installed on barges, ships or floating platforms depending on project specific boundaries and business cases.
