... in isolation, neglecting any interaction between appendages or coupling between rigid body motion and the flexible appendage. As engineering design optimization problems become more complicated, the iterative design process becomes tedious. Derivatives of objectives with respect to design variables speed up...

... of propeller-hull interaction can be very costly in terms of computational effort due to the need to resolve the unsteady flow around the rotating propeller. A popular approach to alleviate this cost, that has seen much practical use in industry, is the use of body forces (momentum sources) to represent...

... Low- and non-ice-class ship-ice interactions are modelled with a shared-energy approach, which typically models the internal mechanics with nonlinear finite element methods. For applications like the preliminary design phase and quick operational assessments of the ship’s structural capabilities...

.... The quality of an implementation of offshore codes and standards in software modules and their interaction among them are measured by defining the level of inter-dependability among the subsea engineering and analysis modules, and by defining the degree of intra-dependability within elements of a module. How...

... Ships interact with the environment in several ways. The focus in this paper is on how ships interact with the wind and how this is treated in design. It is generally sufficient in most cases to model wind force as a static load. However, there may be circumstances where a more detailed...

... This paper introduces a generalized potential/RANS interactive method for the prediction of propulsor performance with emphasis on the calculation of the steady (axisymmetric) or the time-averaged (non-axisymmetric) effective wake fields. This method can be used to handle different types...

... dependent upon vortex interactions with each other and the body. The semi-empirical methods used for comparison yield good predictions for simple vortex interactions but fail where viscous effects are strong. Hence, URANS methods are shown to be necessary for friction-dominated flows while semi-empirical...

Outcomes of the investigation are dependent upon the side force and yawing moment on the distance from the channel border and ice...

... of stringer and web frame prescriptive design strength formulations are available in the literature. These formulations may lead to an overly conservative stringer or web frame section design due to the challenge of representing the grillage section structural component interaction. To properly understand...
