Technical expertise aids ‘critical’ project

FG WilsonFG Wilson, the leading global manufacturer of diesel and gas generator sets, has successfully completed the supply and installation of a high-voltage power solution for the new international terminal of Milas-Bodrum Airport in Turkey

The project was delivered on time and within budget by FGW Jenerator, an official FG Wilson dealer in Turkey.

Milas-Bodrum is one of the busiest airports of the Aegean Region, serving Milas, a residential area with prominent cultural heritage, and the popular holiday destination of Bodrum.

The terminal accommodates more than five million passengers from 40 different locations annually, meaning FG Wilson is helping to support the journeys of almost 14,000 people every day.

The airport’s new international terminal, which is 425m long with an indoor area of over 95,000 sqm, has been provided with a critical standby power system by FGW Jenerator. The five high-voltage generator sets provide backup support for the entire new terminal, including nine passenger boarding bridges, restaurants, retail stores, check-in desks, passenger baggage facilities, information desks, banks and a post office, as well as almost 30,000 sq m of bus and car parking space.

Securing the order against strong competition, the project saw FGW Jenerator make important contributions to the design and specification planning from the outset, as well as liaising closely with other key project partners.

FGW Jenerator’s power solutions team completed the installation and commissioning phase in May 2012, overcoming a series of significant engineering challenges in the process.

Any loss of power at the airport can cause major issues, so it is essential that all critical loads are re-supplied as quickly as possible. In order to achieve this, FGW Jenerator installed five FG Wilson high-voltage P1825 generator sets with the ability to deliver power to the airport distribution network at 6.3 kV.

Due to the critical nature of the application, the management and control of the entire standby power system was implemented using a redundant PLC (programmable logic controller) in conjunction with a user-friendly touch-screen SCADA HMI system.

The primary duty of the PLC system is to ensure the airport is transferred to standby power as quickly as possible on mains failure and on mains return, the load demand of the airport is smoothly and seamlessly transferred to the normal mains supplies.

The generator sets and mains synchronizing capability were implemented using Woodward easYgen 3500 controllers, ensuring that the five generator sets were synchronized and available to take load within 25 seconds of any mains power failure. FGW Jenerator packaged both the PLC system and the five easYgen controllers in an integrated floor standing control panel suite.

To underline the critical nature of this project, each generator set was supplied with two methods of engine starting, air and battery, a capability which delivered increased redundancy and ensured the generator sets could always start and be available to supply the critical airport loads.

To meet the strict noise conditions on site, the cooling system for each generator set was implemented using a combination of a set-mounted heat exchanger and low noise multi-electrical fan remote radiator. Another key element in enabling the noise conditions to be met was the installation in the plantroom of critical exhaust silencers on each engine.

The generator sets are located in a purpose-built generator room on the outskirts of the airport, with remote radiators separating the air start and fuel supply systems. The control, power and synchronization systems are situated in a facility next to the generator room.

The new terminal of the airport is now fully operational. Delighted with the installation and commissioning, Koksal Er, Dealer Principal, FGW Jenerator Turkey, commented: "This is a great example of how FGW Jenerator's technical expertise and experience can provide a complete turnkey customer solution from concept through to commissioning. Having secured the service contract we are looking forward to a long-term, mutually-beneficial relationship with the management team at Bodrum Airport."

FG Wilson products range from 5.5 – 2,500 kVA, including open and enclosed generator sets providing prime and standby power – from standby domestic use, right up to power modules with the ability to operate as complete power stations supplying electricity to national grids.

Through a global network of 380 dealers, FG Wilson serves and supports customers all over the world. With the backup of FG Wilson’s power solutions teams, dealers can meet any power requirement, no matter how complex, the company says.
