SeaFloat SGT-800

SeaFloat Power Plants

Imagine a world with access to electricity and clean water – a world with less pollution, less noise disturbances and sufficient resources. A tough challenge and also a necessity when looking at the world’s growing population and climate change. But this is the world that Siemens Energy wants to fit in – with SeaFloat, the new mobile floating power plant.

Mobility, rapid deployment and flexibility shape our future

We have taken up the idea of floating power plants and brought our latest, highly efficient gas turbine frames on to floating devices, thus defining a new class of floating power plants. The evolution of open and combined cycle power plants from land to sea are based on our successful - gas turbines series (e.g. SGT-800, or SGT-8000H) - proven steam turbine series (e.g. SST-600, SST-5000) as well as our reliable generator series (e.g. SGen-100A, SGen-2000P).

Mobility, flexibility and no need for land acquisition are the most prominent features which distinguish SeaFloat power plants from conventional land-based plants. These features come along with short lead time due to high prefabrication grade and enhanced plug & play concept as well as reduced overall project investments making them interesting for various applications.

It is possible to electrify remote areas with mobile SeaFloat power plants enabling deployment and development and pushing economic growths in these areas.

Being able to provide fast power, countries facing catastrophes such as hurricanes or earthquakes can be supported quickly. Mobile SeaFloat power plants can help to rebuild countries suffering from damaged or destroyed infrastructure, bringing hope to the people and financial securities to banks and lenders.

SeaFloat responses to market requirements

What you can count on

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?

Highly efficient power plants, pre-installed on barges, platforms or vessels may be the right answer.

Rely on our SeaFloat advisory team to help you with business case optimizations and technical support already in early project phases.

This is our SeaFloat power plants range

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.

SGT-800-based SeaFloat Solution

Development of remote areas

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.

Press release

Major order for floating power plant in Dominican Republic

Siemens and the marine arm of ST Engineering in Singapore have jointly received an order for a SCC-800 2x1C SeaFloat barge-mounted power plant from Seaboard Corporation subsidiary Transcontinental Capital Corporation (Bermuda) Ltd., an Independent Power Producer (IPP) with operation in Dominican Republic.

SGT-8000H-based SeaFloat Solution

High performer in heavy duty gas turbines

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.

Offshore application with compact footprint and low weight

Ultra Light Combined Cycle (ULCC)

Modular design for fast and easy installation

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.
