Submerged floating tunnels with suspension supports (SFTSS) resemble to bridges on lands, which are installed a number of hangers the main tower and cables support girder. On other hand, as SFTSS underwater has resist buoyancy forces in an offshore environment, cable was at bottom tunnel body connected hanger. The concept first proposed by Won et al (2019, 2022). It found that generated itself ...

The discussion of hydrodynamic forces becomes an important issue in determining the dynamic behaviour Submerged Floating Tunnel Bridge (SFTB) structure. As stated Morison Equation, are affected by kinematics water particles, but up to this date, there only a few discussions for curved tube applications. This paper discusses effect curvature radius and depth level on get correction factor straig...

Invasion by mats of free-floating plants is among the most important threats to the functioning and biodiversity of freshwater ecosystems ranging from temperate ponds and ditches to tropical lakes. Dark, anoxic conditions under thick floating-plant cover leave little opportunity for animal or plant life, and they can have large negative impacts on fisheries and navigation in tropical lakes. Her...

Abstract Concrete structures suffer from cracking that leads to deterioration and shortening of service life. This is very critical for underwater structures, i.e., immersed bridge piles, tunnel or submerged floating tunnels, which are consistently susceptible ingress harmful ions (chloride, sulphate carbonate ions). Autonomous healing concrete cracks can be beneficial assure durability perform...

As worldwide energy consumption continues to increase, so does the demand for renewable energy sources. The total available wave energy resource for the United States alone is 2,640 TWh/yr; nearly two thirds of the 4,000 TWh of electricity used in the United States each year. It is estimated that nearly half of that available energy is recoverable through wave energy conversion techniques. In t...

A freak wave is a spike in random series and hence the local characteristics time-domain are of key importance. When waves act on moored floating structures, dynamic responses structures time frequency domains change interdependently short period time. It difficult to comprehensively accurately describe this physical process using single-dimensional analysis method, such as statistical or frequ...

A submerged floating tunnel (SFT) is a structure that floats approximately 50 m below the water surface and anchored to seabed by mooring cables. It new alternative conventional bridges immersed tunnels. There have been ongoing efforts construct SFTs worldwide, integrity of these needs be monitored throughout their lifespan. This study simultaneously estimated displacement cable tension force u...
