Standard practice of submarine pipeline installation is by laid on the seabed. The risk in pipeline construction and operation caused by the challenging seabed and environmental load has led to the invention of new technologies of pipeline installation. The greatest risk of conventional pipeline is leakage and the oil will come out and pollute the sea. Innovative concept is offered to overcome that problem where the oil and gas pipeline placed in the Submerged Floating Tunnel (SFT) structure. This paper presents various advantages and points out some obvious disadvantages with this SFT usage for submarine pipeline. Furthermore, the expansion usage of SFT structure in order to house the submarine pipeline will also be presented.
