For a water mist project in Singapore, two IWMA members joined forces: FIPE and FOGTEC. Here are the details:
At a depth of 60 metres lies the superior-type cable tunnel of Singapore Power, the local electricity supplier. It runs over a length of 35 kilometres with a diameter of six to nine metres underneath the entire city to ensure the power supply.
Singapore Power constructed two cross-island transmission cable tunnels to ensure that households and businesses continue to enjoy reliable power supply. The tunnels provide a long-term solution to the ongoing renewal of the power cable grid infrastructure in Singapore. Thomas Fink , Co-Founder of FIPE explains: “A FOGTEC high-pressure water mist system is installed by the local company Deluge to protect the power supply. The construction includes 27,000 FOGTEC nozzles and about 5,500 pipe connections which are being connected with our FIPE system.”
Pipes of 3 inches diameter are used, in order to sustain the pressure over a distance of 37 kilometres in total. Compared to the alternatives in connecting three-inch pipes, the FIPE system leads to substantial time savings and a high-process security of the installation. The installation equipment is highly mobile and therefore very convenient to use especially in areas that are difficult to access such as underground.
The high-pressure water mist system protecting the cable tunnels has been supplied by the Cologne-based company and long term IWMA member FOGTEC. Their special fire protection system has made it possible to install a sustainable and safe solution in the large cable tunnel network. With only one row of nozzles in the upper part of the tunnel, it ensures effective use with smallest amounts of extinguishing agent. Water damages are kept to a minimum. “Our water mist systems are based on specific fire tests and many years of expertise”, says Ruediger Kopp, Managing Director for fixed systems at FOGTEC.
