    24MW emergency power for the Gaziantep Hospital in Turkey

    HIMOINSA has designed and implemented a comprehensive power supply solution to guarantee continuous operation at Gaziantep Hospital, even under extreme conditions. The project also includes the installation of pipelines and advanced soundproofing measures ensuring maximum reliability and safety of the power supply at all times.

    CASE STUDY | 24MW emergency power for the Gaziantep Hospital in Turkey

    PROJECT SUMMARY

    Location: The hospital is located in the Şahinbey district of Gaziantep the province is one of the most important regional healthcare projects in Turkey.
    Installed Equipment:
    1- TSB - the Hospital's Technical Service Centre.
    Genset model installed: 12 HTW 2295.  
    2 - ISM  -the Provincial Health Coordination Centre.
    Genset model installed: 2 HTW 1030.
    Sector:     The project is in the health sector. It is worth mentioning that the Gaziantep City Hospital treats around 45,000 people every day and has a workforce of 6,000 employees.

    Details: The health centre, which serves Gaziantep and the surrounding region, has a capacity of 1,875 patient beds. Its total built area is 638,088 square metres on a site of 330,090 square metres. While the hospital was under construction, the region suffered one of the worst earthquakes in its history. The 7.7 magnitude quake affected the city of Gaziantep (the epicentre of the catastrophe was approximately 170 km far away). The earthquake delayed the opening of the hospital by about six months.

    SITUATION & OBJECTIVE

    The primary objective of HIMOINSA’s project for Gaziantep Hospital was to ensure a reliable and uninterrupted power supply for this mission-critical facility, where continuity of operations is vital for patient care and medical services. Meeting this goal required a highly customized solution that addressed the unique technical and operational challenges of the hospital's energy needs.
    The project aimed to provide a robust backup power system capable of activating instantly during a main grid failure, ensuring seamless transitions and uninterrupted functionality.

    The design required rapid-response generators that could fully energize the system within 10 seconds and supply 100% of the load 20 seconds later, guaranteeing a swift and efficient recovery of all essential hospital services. 

    Another critical objective was to ensure system redundancy and operational reliability. To achieve this, the generators were configured to operate in parallel, allowing automatic switching and reducing the risk of disruptions even in the event of individual generator failure. The solution was also meticulously tailored to meet the hospital’s high power demands, particularly for medical equipment requiring a stable and continuous power supply. 

    In addition to reliability, the project aimed to optimize the system’s design to suit the local conditions of Gaziantep. The generators were installed within the hospital buildings, eliminating the need for external cabins or containers and simplifying maintenance.

    SPECIAL CONFIGURATION
    The synchronisation control system for the 12xHTW2295 package controls the synchronisation of the generator sets at 0,4kV / 34,5kV (medium voltage) downstream of the transformer.
    This system, which uses PLC and HMI technology to manage the generator sets and the MT cells, not only controls synchronisation, but also alerts operators to any alarms occurring in the gensets and manages fuel automation. This synchronisation system communicates with the hospital's Scada system via the Modbus TCP-IP protocol. 

    It controls all the generator sets and auxiliaries based on information received from the hospital's Scada system indicating the need to load, disconnect or reverse synchronise (synchronise with the grid).
    The two HTW1030 generator sets have their own separate synchronisation control system, which is housed elsewhere and also controls the synchronisation at low voltage (400V), with a similar structure and functions

    SOLUTION

    For this mission-critical project, HIMOINSA developed a comprehensive power supply solution specifically designed to ensure the uninterrupted operation of the Gaziantep Hospital. The solution includes special 50 °C+ radiators, synchronisation panels, a fuel system consisting of four main 40 m³ underground tanks and fifteen 1 m³ tanks for everyday use, along with the installation of pipelines and soundproofing.
    It also incorporates critical mufflers, soundproofing cassettes for the air inlet and outlet windows, seismic isolators and mechanical installations to ensure maximum reliability and safety of the power supply at all times.

    Thanks to this solution, we can rely on HIMOINSA as one of our main suppliers for complex and energy-critical applications, not only in the healthcare sector, but in any field and location where high reliability is required".

    Technical solution:

    • 50 ºC radiators.
    • Synchronisation panels.
    • Fuel system.
    • 4 main 40 m³ underground fuel tanks (for the 12xHTW2295).

    INSTALLATION CHALLENGES | HIGH SEISMIC RISK

    Although the February 2023 earthquake delayed the opening of the Gaziantep Hospital by a few months, it also highlighted the need for high-capacity healthcare facilities. Despite the complicated conditions on the ground, the project team showed determination and commitment to complete the installation and commissioning work as quickly as possible. Thanks to the efforts of the technical teams deployed by Himoinsa, Yanmar and the sub-contractors, the project was successfully completed in record time. 

    Critical mufflers
    A critical aspect of this project was the need to reduce noise levels to ensure they met the strict technical specifications. Mufflers were included in the comprehensive noise reduction solution, along with attenuation buffers on the system's air inlet and outlet windows. This configuration made it possible to reduce the noise generated by the units to such an extent that the sound is barely audible from outside the genset room, thereby ensuring that the quiet and safe environment of the hospital is not disturbed. 

    Seismic isolators  
    Installing generator sets in a city such as Gaziantep, located as it is in an area of Turkey prone to considerable seismic activity, presented a major challenge in terms of safety and uninterrupted power supply. Our generator sets are fitted with seismic isolators and are designed to absorb vibrations caused by ground motion and to remain in an upright position. This capability allows the units to continue to operate stably and reliably, even during an earthquake, ensuring an uninterrupted power supply in a critical environment such as a hospital. The disastrous earthquake once again painfully demonstrated the urgent need for these seismic measures.

    50ºC radiators
    Instead of the 40 °C+ radiators that are standard in these HTW packages, 50 °C+radiators were chosen for this project, due to the technical specifications and the ambient temperature requirements of the Gaziantep area. Due to their large size, the radiators had to be transported separately and connected to the engine and chassis at the site.
