The cable tunnel between Tuas Terminal Building and Pioneer Terminal Building is an undersea cable tunnel and is essentially straight with no further deviations throughout the 2.1km tunnel with 2 bores except the inclusion of three vertical tunnel shafts. Each tunnel bore has 4 sets of cables which are fire-rated, oil-filled, sand packed and below the walkway. Most of the tunnel is 2.3m in height with the cables in 0.7m depth of sand packed area. Each tunnel bore is approximately 5m wide.
New Low Pressure Watermist System and Linear Heat Detection System were installed in existing cable tunnel and vertical shafts.
The customer, SPPG Singapore, chose TUNPROTEC® because of its cost effectiveness in actual system cost, assembly and maintenance, and, not least, the technical properties proven by the fire test.
