Abstract [en]

This paper deals with the shortcomings in current design methods for dynamically loaded composite structures in underwater applications. This is done through an experimental study to evaluate the eigenfrequencies of rectangular plates made from metals as well as composites that are tested in air (dry) and completely submerged under water (fully wetted). The eigenfrequencies are studied using forced vibrations. The test series comprises 19 specimens that are made from various materials including aluminium, steel, glass-fibre, and carbon-fibre with aspect ratios varying from 3.7 to 11.2 and breadth to thickness ratios ranging from 2.7 to 20.5. The test method is based on electro-mechanical excitation by random vibrations as well as stepped sine refinements in the vicinity of the identified eigenfrequency. The results clearly show how differently the specimens are affected by the "added mass" from the water when fully wetted compared to the dry condition. Slender and more lightweight configurations are more profoundly affected by water than heavier and more rigid specimens. The results clearly show that for advanced composite materials and more complex geometries the current rule-of-thumb methods used by the industry today are inadequate in predicting the shift in natural frequency due to the effect of the surrounding water.

Abstract [en]

This paper presents and discusses the results of a comparison between using deterministic and ensemble weather forecasts for weather routing. The study is based on comparisons between predicted and realised performance of routes suggested by a route optimization method and focuses on two important performance factors, namely, fuel consumption and late arrival. The study is purely qualitative since the simulations do not include re-routing of the vessel as new forecasts become available. To perform the study a multi-objective dynamic programming method is tailored to the problem and implemented to perform the route optimization and a ship performance model is used to calculate the additional fuel consumption due to wind and waves acting on the ship. The results show that route optimization using ensemble weather forecasts has the potential to reduce the risk of late arrival for voyages during periods of harsh weather.

Abstract [en]

Weather routing decisions are typically based on performance predictions, in terms of estimated time of arrival, ETA, fuel consumption, and consideration of various constraints on the vessel operation such as limitations on allowable acceleration levels or slamming frequencies.

Abstract [en]

Previous studies have shown how the use of composite materials and application of sophisticated design methods can give significantly lighter high-speed craft structures than what is normally achieved for traditional aluminium designs. A reduction in structural mass and a corresponding reduction in displacement improve the craft calm water performance but can be unfavourable regarding the rough water performance. Here, the rough water performance of two versions of a fast patrol vessel, one in aluminium and the other in carbon fibre sandwich, is studied with simplified semi-empirical methods and more advanced non-linear time domain simulations. In speeds up to 30 knots, the rough water performance of the two craft versions is found to be practically equal. At higher speeds, the lighter composite craft experiences higher vertical accelerations than the heavier aluminium craft, which implies less operational availability. Using trim ballast tanks, the rough water performance of the lighter craft is improved, and it is shown that the acceleration levels can be reduced and even lowered relative to the heavier aluminium craft. This means that the calm water advantages of a lighter composite vessel can be utilized with the same ride comfort and operational availability as for a heavier aluminium vessel.

Abstract [en]

This paper addresses the design of composite craft with respect to non-hydromechanic, local loads not explicitly covered in the basic design standards. The primary aim of this paper is to prompt a discussion on these localized assault loads and the associated robustness issue for composite craft. A background and review of craft robustness and resistance to these types of loads is presented to provide a basis for a more nuanced discussion on inherent differences between different material concepts. Through a literature review and interviews with designers and operators different opinions on what is regarded as robust craft and why are identified. Further, a discussion on how progress can be made with respect to designing more efficient craft out of composites, based on the outlining of a possible design approach, is presented.

Abstract [en]

Severe roll angles can be developed by parametric excitation in relatively moderate weather without any apparent pre-warning for the crew onboard. In this study the prospect of using rudder control to mitigate parametric roll was investigated using multi-degree of freedom simulations. A typical modern Pure Car and Truck Carrier was considered and modelled by coupling a roll model with a planar motion manoeuvring model. The combined model was calibrated using in-service, full-scale trials and model tests. Irregular variations of the metacentric height were applied to simulate recorded, full-scale events of parametric roll that have occurred with the considered design. These simulations with rudder roll control showed promising results and demonstrate that the approach could be very efficient for mitigation of parametric roll.

Abstract [en]

The paper considers the hydroelastic interaction involved in panel-water impacts for high-speed craft. Hydroelastic panel-water impacts are simulated by using the finite element code LS-DYNA and a simplified in-house developed method. The mechanisms involved are studied through a systematic series of simulations comprising different impact velocities, deadrise angles, boundary conditions, membrane effects, and panel properties. The terms inertial hydroelastic effects and kinematic hydroelastic effects are introduced to categorize the different mechanisms involved in the hydroelastic problem. It is shown that hydroelastic effects can both increase and reduce the panel responses depending on the impact envelope considered, and it is made clear that the impact envelope has to be carefully considered when establishing the significance of hydroelasticity in a hull-water impact problem. Membrane effects are shown to have large influences on the hydroelastic effects even for moderate panel deflections. The results generated are further used to evaluate and discuss hydroelastic criterion and methods for hydroelastic characterization.
