... performance, the main parameters are set to meet the requirements of stability and economy. An in-house code was programmed to simulate the dynamic response of the articulated offshore wind turbine (AOWT). The aerodynamic load on rotating blades and the wind pressure load on tower are calculated based...

...J. Błachut; O. Ifayefunmi This is the first study into elastic-plastic buckling of unstiffened truncated conical shells under simultaneously acting axial compression and an independent external pressure. This is both a numerical and experimental study. Domains of combined stability are obtained...

...A. Maczyński; S. Wojciech It is often desirable to keep the load of an offshore crane in a fixed point in space despite the movement of its base. To solve the problem of stabilizing the load’s position, the authors have proposed application of the hoisting winch drum’s drive and an auxiliary system...

Based on the deterministic 2DOF coupled roll-heave model with high-degree polynomial...

... to be determined simply in closed form in terms of the single cylinder drag coefficient, the spacing of the two cylinders, and their diameters. The model is applied to static response and dynamic stability of an elastically mounted cylinders. Contributed by the OOAE Division for publication in the JOURNAL...

.... The ultimate objective is to develop accurate yet sufficiently low degree-of-freedom stochastic models suitable for efficient probabilistic stability and reliability analyses of US Naval barges for preliminary design and operation guideline development (see Part II). First a three-degree-of-freedom (3DOF...

.... In these extreme sea conditions, a primary cause for concern is the large accelerations that the vessel motions might experience due to the high static stability of the MOB at Transit Draft. Furthermore, since the vessel has minimum freeboard in this condition, it is exposed to green water over the pontoon tops...

... of dynamically compressed risers was recently derived by Aranha et al. [1], whose results were compared with numerical simulations, showing a good agreement in several cases. This paper extends Aranha’s results by showing that the well-known Greenhill formula can be used to predict stability conditions in cables...

These expressions are used to analyze the influence of the main dimensions in the design of new structures and the use...

... large crude carriers) have been converted to work as FPSOs. However, working as a stationary unit a VLCC presents directional stability problems. In the present paper a methodology is discussed to develop a mathematical model for the simulation and the verification of the stability of a VLCC working...

.... The parametric rolling exhibited the typical subharmonic behavior. The use of classical Mathieu equation theory, coupled with hydrostatic calculations in longitudinal waves, accounting for both vertical motions and wave effect on stability, allows a satisfactory explanation of the observed phenomena. In addition...
