“…Zhao (1995) adopted a governing equation based on the equilibrium of the hoop tension with the pressure difference across the membrane and investigated the response of a floating fluid-membrane system in gravity waves. Zhao and Aarsnes (1998) later included membrane elasticity and compared their numerical results with laboratory data. Phadke and Cheung (1999, 2001 derived linear and nonlinear governing equations based on membrane theory of cylindrical shells and obtained a finite element model for the membrane through the variational method.…”

“…This is a concept for transporting or storing large quantities of fresh water or other liquid lighter than the surrounding water. Such water bags have been subjected to both numerical and experimental studies of the behavior in waves ( [4], [5], [6] and [7]). The closed flexible cage adds, however, to the complexity by having an internal volume of water that has a free surface and an internal flow that is of significant importance to the whole problem.…”

Recent environmental considerations, as salmon lice, escape of farmed fish and release of nutrients, have prompted the aquaculture industry to consider the use of closed fish production systems (CFPS). The use of such systems is considered as one potential way of expanding the salmon production in Norway. To better understand the response in waves of such bags, experiments were conducted with a series of 1:30 scaled models of closed flexible bags. The bags and floater were moored in a wave tank and subjected to series of regular waves (wave period between 0.5 and 1.5 s and wave steepness 1/15, 1/30, and 1/60). Three different geometries were investigated; cylindrical, spherical, and elliptical, and the models were both tested deflated (70% filling level) and inflated (100% filling level). Incident waves were measured together with the horizontal and vertical motion of the floater in two points (front and aft). Visual observations of the response were also done using cameras. The main finding from the experiments were that a deflated bag was more wave compliant than an inflated bag, and that the integrity (whether water entered or left the bag over the floater) was challenged for the inflated bags even for smaller waves (identified as wave condition B (1.0 m < H < 1.9 m) in Norwegian Standard NS 9415). A deflated bag is significantly more seaworthy than an inflated bag when it comes to integrity and motion of the floater.

“…The rigid foundation has been considered in (Kazimierowicz [5]), (Leshchinsky et al [7]), (Malik and Sysala [9]) while the deformable foundation in (Plaut and Suherman [11]). Floating and submerged tubes in water have been considered in (Zhao and Aarsnes [14]). Mathematical attributes as existence and uniqueness of the model solution have been discussed in (Antman and Schagerl [1]), (Malik [8]).…”

We discuss numerical modelling of 2D geosynthetic tubes on rigid and deformable foundation. Our mathematical model is a slight extension of previous ones in (Plaut and Suherman [11]) where the density of slurry material in tubes is constant. Now, density is a function linked to components of slurry material. Also, a simple and efficient numerical method is proposed endorsed by the series of experiments.JOZEF KAČUR et al. 28
