... ABSTRACT Based on a conventional structure cabin, a frame structure cabin is proposed. In order to analyze the damage effects caused by the explosion inside the frame structure cabin, the finite element analysis is used. In this paper, the propagation of implosion load in the frame structure...

..., according to the characteristics of the underwater explosion test of floating shock platform, the structure of black box is designed. Then, the dynamic response of the floating shock platform is calculated using the acoustic-solid coupling method. Based on shock spectrum theory, the acceleration...

INTRODUCTION Air bubble collapse near free surface extensively exist in nature and industrial production and have important applications in underwater explosion, propeller cavitation, drug injection, etc. The high density ratio, high pressure ratio...

... of the scheme are assessed using the popular advecting bubble, the Gas–Liquid Riemann problem, and the under–water explosion. The implementation of surface tension in the scheme is verified via the classic static bubble configuration, and the popular Rayleigh–Plesset collapse problem. For the static bubble...

... was compared for the new type of firewall and concrete firewall, and the conclusions obtained have significant reference value for designing marine platform firewalls. INTRODUCTION There are lots of risk sources on the offshore platform. Any carelessness may cause disaster, such as fire, explosion...

... ABSTRACT Explosive loading was one of the loadings of warship structural under anti-ship missile. The computing method of explosive loading inside closed cabin was the key to calculating the response of stiffened plates accurately. Warship cabins were made up by stiffened plates and stiffeners...

... ABSTRACT In order to investigate on the process of gas cloud explosion in confined space on the platform, an in-house high-resolution code was developed by employing the fifth-order weighted essentially nonoscillatory finite difference (WENO) scheme. What's more, Simplified analytical models...

... Abstract With the development of Ocean Technology, the accidents of offshore floating platforms caused by occasional disasters (such as fire, crash, explosion.) are increasing, which not only causes casualties and heavy economic losses, but also gives rise to the pollution and destruction...
