The project in brief
The cable tunnel between Tuas Terminal Building and Pioneer Terminal Building is an essentially straight undersea cable tunnel with no further deviations throughout the 2.1 km 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 2.3 m in height with the cables in 0.7 m depth of sand packed area. Each tunnel bore is approximately 5 m wide.
