... ABSTRACT In this paper we review loss of containment (LOC) incidents at liquefied petroleum gas (LPG) and liquefied natural gas (LNG) facilities and evaluate regulatory and design requirements, and precautions in producing, transporting, storing, and using LPG and LNG. We identify damage...

... ABSTRACT In recent years it has been reported a number of incidents related to failures of high-strength mooring chains used in mobile offshore units mooring systems. Different investigations have been carried out resulting in several explanations for why these incidents occur, and several...

... into the superposition of plane waves as the incident sound field by spatial Fourier transformation. Then, the transmission of each plane wave component after incident on the solid plate is superimposed to obtain the total transmitted sound field according the angular spectrum method, the result is also verified...

... ABSTRACT Accidental water pollution incidents, usually in the form of point source, are potential threats to the local drinking water sources. In this study, a two-dimensional water quality model was developed using Delft3D software, aiming to investigate the effect of such accidental...

..., environmental pollution, and reduction in oil security. Each event has a unique set of factors that directly caused or contributed to the incident, including process automation, human interaction, safety culture, regulatory compliance, and engineering practices. Accurately identifying the key causal factors...

... segment of the Grand Canal, which has a vertical revetment structure. Water surface fluctuations caused by 220 groups of ships were recorded. The incident and reflected waves were separated from the recorded waves based on a proposed mathematical model. Then, the average reflection coefficients...

... prediction of the wave surface, separating them into incident and reflective components. From the results, it is evident that the wave absorber comprised of a hard filling material exhibits a better performance than the absorber comprised of soft material; i.e., the wave absorber can be a strong sink...

... Abstract The purpose of this study is to clarify the submerged step height effects on the harmonic generation using a vertically two-dimensional numerical wave flume. Eighteen experimental conditions were carried out, including different incident wave heights, periods and two step heights...

... Abstract The past decade has seen 21 mooring incidents reported on Floating Production Systems (FPS), with 8 classed as system failures. This paper highlights the requirement for monitoring of mooring lines and provides a case study of a non intrusive, retrofittable, anchor leg load monitoring...

ABSTRACT: Forecasts of wind and wave power incident to the coastal region of Santa Cruz, California, USA, show highs and lows every few days and numerous days between periods of power density exceeding the monthly average power. This unsteadiness can cause complex systems and design approaches...
