Design and Operation of Automated Container Storage Systems

   The container box is sometimes hailed as one of the ten greatest inventions of the last century and has certainly transformed the way cargo moves around the world. This is due to the fact that different goods—which would otherwise require individual loading procedures using specialised machinery along their shipment routes—can be packed into such containers of various sizes and thus become standardised transportation objects. This makes them amenable to handling in seaports and other hubs by readily available equipment such as quay cranes, straddle carriers and gantry cranes. The latter are often used to store, retrieve and shuffle containers in a container-storage yard. Such yards are typically divided into several blocks. Depending on the overall design of the storage yard, the cranes can either be rather flexibly driven around the entire yard (so-called Rubber-Tyred Gantry Cranes, RTGC) or are installed on rail tracks along each block (Rail-Mounted Gantry Cranes, RMGC); these cranes are hence mainly dedicated to a particular block. In contrast to an RTGC which always requires a driver for each crane, RMGC systems can be largely automated and are hence very efficient which becomes increasingly more important—in particular, in high labour-cost countries. Of course, the potential savings in salaries of such a highly automated system incur a comparably higher up-front investment for equipment that cannot easily be used in different blocks of the yard. An efficient planning and operation of such a yard block is therefore highly relevant for achieving a sufficient utilisation of the block in order to tip the cost balance in favour of such a system...

Verification of Lifting Appliances for the Oil and Gas Industry

   The selection of the level of verification shall depend on the risk level of each of the elements that have an impact on the management of hazards and associated risk levels of the asset. The planning can be simplified or detailed. This is further described in DNV-OSS-300. This specification mainly aids in a simplified preparation of the Verification Plan. Verification describes the individual activities undertaken by DNV at the various stages of design-construction and operation of the facility. The scope of the verification plan is ultimately determined by the Client. A statement of Compliance may be issued by DNV to confirm compliance according to the scope of work. Certification describes the totality of verification activities leading up to the issue of a Certificate of Conformity. The scope of work and verification plan, called a Certification Plan, is set by DNV. All design and construction aspects, related to process facility safety and integrity, must be covered by the Certification Plan. In the event that DNV does not define the scope of work necessary to achieve certification, a certificate of Lifting Appliance shall not be issued.

Advanced Shiphandling

   The experienced seaman and ship designer know jus! what the sea at its worst can do to the structure of a ship. Overwhelmed by the sea is a warning to both seafarer and architect that such unforgiving force must never be underestimated, and may not yet be fully understood. Let us look at a large cargo ship on a winter passage across the North Atlantic from Europe to North America. Her Master will have received regular weather reports and will have plotted his route in an effort to minimize the effects of heavy weather, but such is the depth and frequency of the giant depressions that remorselessly track across the Western Ocean in winter, that it is unlikely that he can avoid their effects entirely. Sooner or later the ship will find itself laboring against the worst that nature can throw at it. It is on such occasions that the complex structure of steel and systems which make up the modern ship will be tested to the limit. While the Master can adjust his speed and course to minimize the effects of the storm, his job is to get to his port of destination without too much delay, balancing the risk of damage against the cost of a late arrival, trusting in his skill as a ship handler and the strength of his ship.

STAB 1986 - Third International Conference on Stability of Ships and Ocean Vehicles - Gdansk

   Аs long as shipping existed ships were exposed to the hostile environment and shipbuilders from the oldest times lerned that in order to survive in this environment ships had to stable. They developed also by trial and error method the practical knowledge how to build comparatively stable ships, however hot stable enough to ensure safe completion of the voyage. In modern times understanding of basic laws of ship's geometry and static stability enabled naval architects to make calculations during the design stage, then developments in ship hydrodynamics allowed to calculate the behaviour of ship in a seaway and the effect of external forces on stabillity. Nevertheless from time to time ships were lost as a result of capsizing quite often with all hands onboard. Even introduction by some nations of stability regulations which also included certain stability criteria did not eliminate casualties.

Container Terminals and Automated Transport Systems

   In most existing container terminals, computers are employed to schedule and control different kinds of handling operations. A container terminal is a complex system with various interrelated components. Hence, there are many difficult decisions that operators and planners have to make. Because computer systems have capabilities to maintain a large volume of data and analyze them in a short time. they have been utilized to assist human experts in making decisions on the design of a container terminal, in developing operational plans and supporting real time decisions, for instance. Furthermore, there is an ongoing trend in the development of seaport container terminal configurations to use automated container handling and transportation technology, particularly, in countries with high labour costs. This in turn requires a much more sophisticated control strategy in order to meet the desired performance measures. As a result, quantitative methodology has received considerable attention to analyze and support the design, operations, and control issues arising in automated container terminals. Clearly, container terminal logistics is a challenging field for many research disciplines, e.g. industrial engineering, automation, operations research, and management. Yet, given the recent developments in information technology, automated handling and transportation equipment, optimization algorithms and modelling tools, the overall productivity of container terminals can be significantly increased...

Environmental Load Factors and System Strength Evaluation of Offshore Jacket Platforms

   API RP2A Working Stress Design (WSD) forms the basis of offshore steel Jacket platform design all over the world and has proved to be accepted design standard since it was first issued in 1969. WSD is a factor of safety-based code which is derived from WSD theory and reduces the ultimate resistance strength to allowable stress for safe design. In WSD. minimum resistance results from test results of yield strength and for load from past experience; thus, safety factor was inherent in these codes though not apparent. Since the loads/resistances are varying, the assumptions used in WSD design process, i.e. a single factor of safety for all load combinations, cannot maintain a constant level of structural safety. WSD method uses safety factors without taking into consideration the uncertainties, and it assumes that all variables are deterministic. Thus, safety of platform is achieved by WSD through the use of a factor of safety against the inherent uncertainties of load and resistance. For allowable stress design, safety of structure is achieved by the use of a safety factor against the uncertainties of load using some arbitrary experience and judgment like 1/3 decrease for allowable stresses. This method provides no knowledge about effects of various random variable parameters on the safety of Jacket platform...
