“…Due to the trend of large-scale liquid cargo ships, it is of great significance to study the coupled motion response of ships with tanks in beam waves. He et al [11] used the CFD method and experiments to study the response of a ship with/without a tank in beam waves. In their paper, several different working conditions are set up, and the effects of the liquid height in the tank, the size of the tank and the wavelength ratio of the incident wave on the ship's motion are studied.…”

“…Armenio et al [6,7] and Li et al [8] independently developed coupled numerical models based on computational fluid dynamics (CFD) for the coupled effects. After Li et al [8], many studies have been conducted on this topic in recent years (e.g., Huang et al [9], Taskar et al [10], Jiang et al [11], Cercos-Pita et al [12], Ghamari et al [13], Saripilli and Sen [14], Bulian and Cercos-Pita [15], Diebold et al [16], Alujević et al [17], Lyu et al [18], Zhuang and Wan [19], Alujević et al [20], Subramanian et al [21], Wei et al [22], Bernal-Colio et al [23], Liu et al [24], Yao et al [25], He et al [26], Lin et al [27], Liu et al [28], Lyu et al [29], Sun et al [30], Wen et al [31], Yu et al [32], Chen et al [33], Chen et al [34], Ge et al [35], Kapsenberg and Carette [36], Lee et al [37], Lin et al [38], and Wang et al [39]). However, the dynamics of the ships and floating caissons are different.…”

Floating caissons can oscillate owing to ocean waves when towed to an installation site. To reduce these oscillations, free-surface anti-oscillation tanks mounted on floating caissons have been proposed. However, no coupled numerical model exists between the motion of the floating caisson and fluid flow in the tanks based on computational fluid dynamics (CFD). In this study, a coupled model is developed and compared to existing physical experiments for validation. In the coupled model, the vertical and rotational motion of the floating caisson are computed as a rigid body, and the motion of the free water in the tank is computed using a CFD model. Numerical results show the predictive capability of the coupled model in terms of the rotational motion (pitch) of the floating caisson within ±20% of experimental data, regardless of the absence or presence of water in the tank. The numerical results also show that the fluid flow with complex air–water interface motion in the tank can be analyzed in detail using the coupled model. This suggests that the coupled model developed in this study is a useful tool for quantitatively assessing the effectiveness of an anti-oscillation tank for reducing the pitch of a floating caisson.

“…In continuation, Akyildiz [11] investigated the roll dynamics of a partially-filled rectangular tank with a vertical baffle by varying the ratio of baffle height to initial liquid depth. He et al [12] conducted a validation experiment for rectangular tanks and beam waves. Bulian et al [13] developed a six degree-of-freedom (DOF) ship motion numerical solver by coupling rigid-body dynamics and external fluid-structure interaction with a smoothed-particle hydrodynamics solver to analyse the internal sloshing dynamics.…”

Conventional liquefied natural gas (LNG) cargo vessels are imposed with tank-fill limitations as precautions to prevent structural damage and stability-loss due to high-impact sloshing, enforcing cargo volume-fills to be lower than 10% or higher than 70% of the tank height. The restrictions, however, limit commercial operations, specifically when handling spot trades and offshore loading/unloading at multiple ports along a shipping route. The study puts forward a computational fluid dynamic (CFD) sloshing analysis of partially-filled chamfered rectangular tanks undergoing sinusoidal oscillatory kinetics with the use of the explicit volume-of-fluid and non-iterative time-advancement schemes utilising the commercial solver ANSYS-Fluent. Establishing a 20% to 60% fill-range, the sloshing dynamics were acknowledged within an open-bore, partitioned, and perforated-partitioned tank when oscillating at frequencies of 0.5 Hz and 1 Hz. The overall torque and static pressure induced on the tank walls were investigated. High-impact slamming at the tank roof occurred at 40% and 60% fills, however, the implementation of the partition and perforated-partition barriers successfully reduced the impact due to suppression and dissipation of the wave dynamics.
