CFD simulation of the passing vessel effects on moored vessel

TL;DR: It is observed from the results that the longitudinal and transverse forces on the moored vessel become negligible for separation distance more than three times the width of the vessel.
Abstract: In recent years, there has been an increased use of large displacement vessels for cargo transport around the world. Due to space constraints in the matured ports, the clearance available between t...

TL;DR: In this article, the effects of passing distance, speed and size of a passing ship on the lateral motion of a moored vessel were investigated and the effect of the stiffness of the mooring system on lateral motion was investigated.
Abstract: Deals with some preliminary results of model tests carried out in the wave and current laboratory of the Netherlands Ship Model Basin to determine the external forces on a tanker, moored in shallow water, as a result of the passage of a large tanker shaped vessel. The main effects of passing distance, speed and size of the passing tanker are shown. It will be discussed how the response of the moored vessel may be calculated from the exciting forces measured. A calculation of the lateral motion of a tanker moored by means of linear springs illustrates the calculation procedure and supplies interesting information concerning the effect of the stiffness of the mooring system on the lateral mooring forces.

TL;DR: In this paper, the authors proposed a methodology and developed a numerical program to predict the ship-to-ship interaction during overtaking operations in shallow water, where the vessels involved in this study have different forward speeds, an uncoupled method will be used to solve the boundary value problem.
Abstract: Hydrodynamic interaction continues to be a major contributory factor in marine casualties and hazardous incidents, in particular, in the case of overtaking operations. The situation becomes even worse when the overtaking operation occurs in shallow and narrow channels, where the interaction can cause the vessels to collide and, in one case has caused the capsizal of the smaller vessel with loss of life. The aim of this article is to propose a methodology, as well as to discuss the development of a numerical program, to predict the ship-to-ship interaction during overtaking operations in shallow water. Since the vessels involved in this study have different forward speeds, an uncoupled method will be used to solve the boundary value problem. The in-house multibody hydrodynamic interaction program MHydro, which is based on the 3D Rankine source method, is used and extended here to investigate the interactive forces and wave patterns between two ships during an overtaking operation. The calculations given in this article are compared with model test results as well as published computational fluid dynamics (CFD) calculations. Very satisfactory agreement has been obtained, which indicates that the proposed methodology and developed program are successfully validated to predict the hydrodynamic interaction between two ships advancing in confined waters. The discussions also highlight the speed effects.

TL;DR: In this paper, the effect of hydrodynamic interaction due to a steadily moving ship on a fixed vessel is derived as a function of the passing ship speed, the geometrical particulars of the two ships, their separation distance between ship centerlines, and the harbor water depth.
Abstract: A moored ship may experience strong disturbances even in a calm basin when other ships pass along at a sufficiently close range. These disturbances may be so strong in some instances that the sustained stress on the mooring lines might possibly exceed their breaking strength and result in breakage. The objective of this paper is to provide an engineering guide in estimating these loadings on moored ships, as this information should be of utmost value to harbor and ship engineers in securing berthing and mooring safety. The problem is investigated by using slender body theory approach. The effect of hydrodynamic interaction due to a steadily moving ship on a fixed vessel is derived. The resulting surge force, sway force and yaw moment acting on the moored ship are shown as a function of the passing-ship speed, the geometrical particulars of the two ships, their separation distance between ship centerlines, and the harbor water depth. Calculated results are presented graphically.

TL;DR: In this paper, a set of empirical equations are proposed that provide improved descriptions of the measured peak mooring loads on a moored ship resulting from a passing ship moving parallel to the moored vessel, including changes in the passing vessel speed, vessel displacement, water depth and separation distance between the two ships.
Abstract: Laboratory tests were conducted to measure the loads on a moored ship resulting from a passing ship moving parallel to the moored vessel. The tests included changes in the passing vessel speed, vessel displacement, water depth, and separation distance between the two ships. Measurements were made of the surge forces, sway forces, and yaw moments. Two existing predictive models were evaluated in “blind” tests to determine their ability to predict the measured mooring loads. A new set of empirical equations are then proposed that provide improved descriptions of the measured peak mooring loads.
