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 wants to fit in – with SeaFloat, the new mobile floating power plant.

SeaFloat power plants will support New York's renewable energy strategy

Astoria Generating Company and Siemens signed a contract for the turnkey construction of two SeaFloat power plants to be equipped with eight Siemens SGT·A65 gas turbines. 

Introduction

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, SGT-A65 and 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.

Floating power plants’ unique characteristic is the ability to deliver them in one piece; almost completely pre-installed following a smart plug & play philosophy. Our new SeaFloat floating power plant concepts can be utilized for mobile and/or permanent installation to alleviate energy shortages for national grid or industrial application. Mobility, flexibility, decentralized power generation, shorter construction time, reliable technology, robust design, optimization for easy maintenance bring benefits and increase your added value. 

Portfolio

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,SGT-A65), 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 Future of Energy with Floating Power Plants

The SeaFloat technology combines state-of-the-art combined cyle power plant technology with the mobility and flexibility required by the current and future energy market. 

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.

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-A65-based SeaFloat Solution

Fast and flexible

An SGT-A65 SeaFloat power plant offers fast delivery and installation of a highly flexible power generation plant without the requirement of high transmission voltage connections.

 

This product can also provide potable water manufactured from sea or brackish water as a byproduct.

 

It is a dual-fuel dual-frequency floating power barge providing unparalleled operational flexibility, high ambient temperature power output levels and excellent support services including black start for weak grids. The SGT-A65 can also be operated with 100% hydrogen and it is an important player for floating Power-to-X application.

Using the latest highest-efficiency aero-engine technology at its core, the lightweight SGT-A65 gas turbine is designed to withstand the most demanding high-cycling operating profiles without incurring maintenance penalties.

This SeaFloat product is of major importance for applications that require fast delivery, power for isolated or remote locations, grid reinforcing for the short or medium term and disaster relief situations.
