... This study presents the concept of a small autonomous catamaran for operation in remote offshore areas for long duration. The relative linear motion between the hulls and the main deck is converted into a rotational motion of an electrical generator to harvest wave energy for supplemental...

... Ever since Titanic was found in 1985 and it was discovered that the ship did not sink intact there have been a number of theories as how the ship’s hull failed. This paper will discuss several of these theories and discuss the reasons for the necessity of superseding them as new information...

.... Free-running models tested in open water can overcome some of these limitations. This paper presents the detailed design of a free-running model for open water experimental application. The model development includes hull construction, design and integration of a propulsion & steering system, data...

... Semi-submersible vehicles have low-profile platforms above the water surface while keeping most of their hulls below waterline. In addition to reduced detectability, these craft may potentially have good seaworthiness and hydrodynamic advantage at fast displacement speeds. In this study...

..., this enables the impact probability to be mapped onto the hull. Vulnerable areas of the hull are identified by showing only impacts that are hard enough to exceed the local structural capability. Operational guidance to mitigate the risks is obtained by repeating this at different speeds and headings. Applying...

These derivatives are being inserted in a simulation maneuvering model for the prediction of the maneuvering performance. It should be noted that the hull, which is subjected to the virtual captive model tests...

... Significant frictional drag reduction of ships and boats can be achieved by forming extended air cavities underneath hulls. However, the air cavity benefit may degrade or disappear in off-design loadings and speed regimes, as well as in rough seas. To make this technology more viable, means...
