Siemens Energy has won a contract from eTEC E&C to supply a two-cylinder steam turbine with an associated generator for the 250MW Seagull project in Gunsan City, South Korea.

Under the contract, Siemens will supply a two-cylinder steam turbine set with reheat capability, consisting of an SST-800 turbine and a double-flow SST-500 turbine and an associated SGen6-100A generator with both steam turbines being arranged on one shaft and drive the same generator.

As the EPC contractor, eTEC E&C is developing the cogeneration plant for its subsidiary Gunjang Energy, and delivery from the Görlitz plant is set for June 2015 with the Seagull plant scheduled to begin heat and electricity generation in the second quarter of 2016.

The plant supplies electricity for the grid and heat for the surrounding industries, offering classic cogeneration with maximum energy efficiency.

The latest contract is part of the Seagull project’s expansion phase to ensure a reliable power supply in the region around Gunsan.

Having delivered an SST-600 and an SST-300 industrial steam turbine, which were already put into operations, Siemens is working on a second SST-600 turbine, which is currently nearing completion.

Siemens Energy steam turbines business unit CEO Wilfried Ulm said the company has received a follow-on order for the Seagull project in South Korea.

"The latest contract is part of the Seagull project’s expansion phase to ensure a reliable power supply in the region around Gunsan."

"After its completion, Seagull will be the most efficient and most modern coal-fired cogeneration plant in South Korea With this order, we were once again able to score points in South Korea with our energy-efficient technologies," said Ulm.

Gunjang Energy president Chang-Suk OH said, "We once again opted for Siemens since we had very good experiences in the previous projects. With our new power plant, we will be able to reliably provide electricity in the region around Gunsan as well as supply process steam to the industrial segment."

In January 2014, Foster Wheeler was awarded a contract for the design and supply of a circulating fluidised-bed (CFB) steam generator for the project.

As per the contract, Foster Wheeler will provide the 250MWe steam generator, including a selective catalytic reduction system, and provide technical advisory services during erection and commissioning, while its licensee BHI will provide local fabrication and sourcing to meet eTEC’s delivery schedule.
