Submerged Floating Tunnels - Sensitivity in High Currents

Abstract

<p>This paper outlines aspects of the work completed as part of a feasibility study on behalf of the Philippines Government for a permanent crossing between Sorsogan and Samar islands. An optioneering exercise identified the possibility of a Submerged Floating Tunnel (SFT) to be designed as the permanent crossing. The relatively high speed and the bidirectional current in this location required an iterative series of sensitivity tests for a net buoyant SFT solution. These sensitivity tests are defined and explained, and their results are presented for future SFT designs in high currents.</p>
