Heavy lift semi-submersible ships utilization in offshore wind turbines industry

Many technologies and initiatives have been developed across the world to produce power from renewable resources. One of these technologies is offshore wind power that utilize wind turbines established in water to generate electricity. Offshore wind power generates more electricity per unit of capacity installed due to offshore wind velocity is higher than on land. Wind turbines are difficult to transport because of their huge towers and nacelles, as well as their long, delicate blades, hub, and generator. In order to transport these huge parts specialized ships to handle it and help in its transportation safely with the minimum costs and hazards are needed. Semi-submersible heavy-lift ships are primarily designed to transport extremely large and heavy cargoes, which are loaded using the float-on/float-off method, and large non-floating equipment. A high-capacity ballast system is installed on the heavy lift ships. When loading and unloading cargo, a ballast system is needed to manage heeling and trimming moments. Several accidents have occurred during the submerging process, these accidents result was sinking of many ships. Results are presented and discussed.

Legal, decent, honest, and truthful

Popeye, “strong to the finish, ‘cos he eats his spinach,” and Jack Sprat, who would eat no fat (and his wife would eat no lean), seem to have inspired the Meat and Livestock Commission's campaign Meat Matters, which is aimed at consumers, health professionals, and journalists. One of the eye catching national advertisements compares the dietary iron contained in a huge tower of raw spinach on one plate and a grilled steak on the other. A great photo opportunity, but not quite the “rational” approach boasted by the commission. Although steak ranks highly among meats in iron content, spinach is not the front runner among plant sources. Indeed, Popeye might have done better to take a spoonful of black molasses since, gram for gram, molasses, cashew nuts, soya beans, wholemeal bread, and even popadums provide considerably more, and better absorbed, iron than does spinach. A more equitable approach, although less visually striking, would have compared similar portions of cooked soya …

A STATIC AND DYNAMIC NONLINEAR BEHAVIOUR OF STEEL TOWERS OF LONG-SPAN SUSPENSION BRIDGES SUBJECT TO WIND AND EARTHQUAKE LOADINGS

The static ultimate strength analyses of the tower-cable system of Akashi-Kaikyo Bridge are performed for the investigations of the planar and spatial behaviour of the structures subject to a variety of the combinations of the vertical dead and live loads, and the horizontal wind loads both in the directions of perpendicular-to-bridge axis and bridge axis. The obtained ultimate loads based on three different loading paths are compared with the design loads specified in the current codes of huge towers. The nonlinear dynamic responses of the planar tower and tower-cable models are obtained to examine the safety of the superstructures of Akashi towers against horizontal ground motions of the 1940 El Centro record with variable amplitudes up to four times the design acceleration specified in the codes.

A NONLINEAR BEHAVIOUR AND STRENGTH OF STEEL TOWERS OF LONG-SPAN SUSPENSION BRIDGES SUBJECT TO DEAD AND LIVE LOADS

An ultimate strength analysis of the steel towers of the long-span suspension bridges is presented within the framework of an inelastic finite displacement theory of planar and spatial structures. The combined tower-cable system is employed to study the nonlinear effect of cables on the behaviour of huge towers. The Akashi-Kaikyo Bridge now under the first stage of construction for its seabed is selected in this study for investigations of ultimate strength behaviour of its steel towers subjected to the vertical dead and live loads. The current design practice of the Akashi towers is examined based on the present numerical results.
