This paper provides an introduction to shipboard signage design, construction, and installation. It is intended to assist the naval architect and marine engineer in the design of signs for shipboard use, help the shipyard in its initial procurement and installation of shipboard signage, help the ship's crew determine what additional signs are needed during the life cycle of the vessel, and aid in the sign replacement process. There are a number of standards and specifications, both commercial and military, that deal with signage but few are in complete agreement. Research into these standards has resulted in the development of a user-friendly shipboard signage guide, applicable to both military and commercial vessels, which is paraphrased in this paper. Guidance is provided for the most commonly used shipboard signage applications and includes the use of new materials which are less expensive, lighter weight, and more visible even in low or no light conditions. By using this guide, effective signs which offer reduced cost (material and installation) and weight, with improved readability, clarity, and meaning will result. Specific areas addressed include signage types, layout, wording, symbology, physical properties, installation, and cost.

the article deals with the main causes of accidents of buildings and structures that occurred due to errors made at different stages of their life cycle (design, construction, operation). A brief analysis of the accidents that occurred from 2010 to 2017 in the Russian Federation is presented. The study of the causes of accidents makes it possible to understand better the laws of structures, buildings and structures, to identify errors that lead to emergencies. Such errors include: low quality of construction and installation works, deviation from the project in the construction of buildings and structures, the use of materials of inadequate quality, overload of load-bearing structures during operation. Also, the causes of accidents include defective engineering-geological and hydrogeological studies of the grounds. Analysis of accidents showed that the last few years there is no tendency to reduce the number of accidents of buildings and structures, which indicates an insufficient number of measures to prevent them. In the article the authors consider the examples of accidents in construction, which occurred due to the main reasons, and ways to prevent accidents in the future.

BIM is a data tool used in various stages of design, construction and management. It can integrate different models of buildings and realize sharing and transmission during the life cycle of the project, ensuring that engineering technicians can access different building information with a correct understanding and real-time response, it lays a good foundation for different participants including design, construction and management to achieve collaborative work. It is very important whether it is to ensure production efficiency, save costs and shorten construction periods. For the newly emerging prefabricated buildings, their structural design will become more efficient, accurate and reasonable due to the introduction of BIM technology.

By looking backwards we can often discover solutions that will allow forward progress. We see in the bible the idea that history repeats itself: What has been will be again, what has been done will be done again; there is nothing new under the sun. Ecclesiastes 1:9 But the author subscribes to the idea put forward by the American humorist, Mark Twain: History doesn’t repeat itself, but sometimes it rhymes. The design and construction of water-borne craft using “scientific” methods is a relatively recent development in the context of the whole history of that activity, and is by no means universally applied even today Many traditional craft in current service still rely on the process akin to natural selection, as proposed by Darwin, that is, it is not the strongest, most intelligent nor the fittest that survive but those that best adapt. And the evolutionary process continues today. From Bangkok water taxis with “long-tail” propulsion systems, and from Haitian fishing boats with high performance new sails to whaling umiaks in NW Alaska covered with tensioned membrane skins made from walrus hide and equipped with outboard motors, there can be value in studying the design, construction and operational approaches of these craft. Such consideration can lead to insights for the modern naval architect. A number of well-researched publications (Tapan Adney, 1964) and (Haddon, 1975) give a wealth of information on indigenous craft. Sturgeon Nose Canoe USN ZUMWALT Class Destroyer. Noble Lessons to be learned from the study of indigenous craft 2 Lessons such as optimizing weight/strength ratios, minimizing resistance, utilizing materials in clever ways, developing repairable structures etc., can all be learned from the study of indigenous craft. The sense of continuity with a living past obtained by the study of the work of previous generations of designers and builders, realizing that many current problems were their problems too, is both valuable and satisfying. That said, not all examples given in this paper can be directly linked to designers actively seeking out past developments. Some examples have occurred by coincidence, some by accident and some by unwitting “reinvention of the wheel”. Many “new” ideas, however, have been tried before and it is very often possible to test a new idea against past experience. This paper builds on previous ethno-technical study, (Noble 1994) describing the author’s experience in this field and uses a number of specific examples to illustrate the premise.

Reduction of human error can have a significant impact on the potential for spills and leaks and translate into better safety performance and financial gains for an organization. As important as the technical components of a design, construction, operation, and maintenance program is the human component of the activities being performed. In the Pipeline Industry, human factors can create the potential for a human error at many points along the life cycle of a pipeline. Using a life cycle approach to manage human factors can provide an organization the capability to integrate human factors into programs, standards, procedures and processes using a disciplined approach. This paper reviews the life cycle of a pipeline and identifies areas where the potential for human error can have catastrophic results. Guidance is provided on the development of a human factors life cycle for the organization and illustrates available industry resources as well as opportunities for further research and development.

Current American Society of Mechanical Engineers (ASME) nuclear codes and standards rely primarily on deterministic and mechanistic approaches to design. The design code is a separate volume from the code for inservice inspections and both are separate from the standards for operations and maintenance. The ASME code for inservice inspections and code for nuclear plant operations and maintenance have adopted risk-informed methodologies for inservice inspection, preventive maintenance, and repair and replacement decisions. The American Institute of Steel Construction and the American Concrete Institute have incorporated risk-informed probabilistic methodologies into their design codes. It is proposed that the ASME nuclear code should undergo a planned evolution that integrates the various nuclear codes and standards and adopts a risk-informed approach across a facility life-cycle — encompassing design, construction, operation, maintenance and closure.

The importance of building energy performance has been substantially increasing in the last decades due to the global warming. Therefore, buildings within the existing stock and the new buildings are encouraged to achieve the energy performance restrictions and efficiency levels. In this context, a social housing archetype (Harct), which is constructed in each climate region of Turkey with a common design approach for temperate climate region, is evaluated as a base case to improve the energy performance for the cold climate region by the optimization of the life cycle cost (LCC). It is, namely, aimed to not only improve the energy performance of the archetype but also to ensure optimal cost efficiency as significant criterion. It is focused to optimize the façades of the Harct in terms of window width, and optic and thermo-physical properties of the façade with determining the efficient insulation thickness level for exterior walls and efficient glazing types for windows. Firstly, façade design is analysed to find out the minimum and maximum windows’ widths to achieve the optimal window sizes. Secondly, optic and thermo-physical properties and cost data of the opaque and transparent façade elements have been designated among the market products in accordance with the current regulations. Energy model of the building has been run by Energy Plus simulation tool, in order to integrate it with GenOpt for optimization. Optimization was performed to carry out efficient frontier cases. The results were evaluated from life cycle cost (LCC) and energy efficiency point of view to highlight the cost optimal point
