Transient effects of tendon disconnection on the survivability of a TLP in moderate-strength hurricane condition

Abstract

The primary objective of this paper is to investigate the dynamic stability and survivability of a four-column classic TLP(tension-leg platform) under less-than-extreme storm conditions where one or more tendons have been lost due to damage or disconnect. The transient responses of the platform and tendon tensions at the moment of disconnection are in time domain. Compared to the common industry practice of checking the system without a failed tendon on the beginning, the maximum tension on the neighboring tendon can be significantly increased at the moment of disconnection due to the snap-like transient effects, which can lead to unexpected failure of the total system. It is also found that the transient effects can be reduced with the presence of TTRs (top-tensioned risers) with pneumatic tensioners. It is also seen that TLP cannot survive in the 100-yr hurricane condition after losing one tendon

The Power of Micro Urban Structures, Theory of EEPGC - the Micro Urban Energy Distribution Model as a Planning Tool for Sustainable City Development

Abstract

To achieve the smart growth and equitable development in the region, urban planners should consider also lateral energies represented by the energy urban models like further proposed EEPGC focused on energy distribution via connections among micro-urban structures, their onsite renewable resources and the perception of micro-urban structures as decentralized energy carriers based on pre industrialized era. These structures are still variously bound when part of greater patterns. After the industrial revolution the main traded goods became energy in its various forms. The EEPGC is focused on sustainable energy transportation distances between the villages and the city, described by the virtual “energy circles”. This more human scale urbanization, boost the economy in micro-urban areas, rising along with clean energy available in situ that surely gives a different perspective to human quality of life in contrast to overcrowded multicultural mega-urban structures facing generations of problems and struggling to survive as a whole.

Development of data analysis tool for combat system integration

ABSTRACT

System integration is an important element for the construction of naval combat ships. In particular, because impeccable combat system integration together with the sensors and weapons can ensure the combat capability and survivability of the ship, the integrated performance of the combat system should be verified and validated whether or not it fulfills the requirements of the end user. In order to conduct systematic verification and validation, a data analysis tool is requisite. This paper suggests the Data Extraction, Recording and Analysis Tool (DERAT) for the data analysis of the integrated performance of the combat system, including the functional definition, architecture and effectiveness of the DERAT by presenting the test results.

The Influence of Attack Helicopter Modernization on Pilot Decision Process

The Influence of Attack Helicopter Modernization on Pilot Decision Process

The proper maintenance of attack helicopters is the basis of the Army Aviation operational effectiveness.

In order to improve the effectiveness of the air support to the Army, this modernization of attack helicopters should be done. It is essential for increasing performance indicators of the Army Aviation. The project of modernization should consider improvement of attack helicopter survivability by increasing resistance to destruction. This aspect has a crucial impact on a pilot decision process during a flight. That is why the modernization should be considered in technical, economic and flying aspects.

From Reliability to Resilience: Modern Challenges of Safety and Reliability Theory and Applications / Od Nieuszkadzalności Do Odporności: Współczesne Wyzwania Teorii i Inżynierii Niezawodności i Bezpieczeństwa

Abstract

There are several trends of development of modern reliability theory; some of them are subjects of everyday engineering activity, like: quality control of mass production or “pure” reliability. But most of these issues, such as: effectiveness, survivability, safety, security, are currently the subject of many works of conceptual, modeling, case study or survey nature. The aim of this article is show how the performance requirements of technical objects were supplemented with: customer expectations (quality), abilities to prevent the loss of the object properties in operation time (reliability and maintainability), the effects of undesirable events and protection against them (safety and security) and the ability to restore performance (resilience).

The water retention of a granite rock fragments in High Tatras stony soils

The water retention of a granite rock fragments in High Tatras stony soils

The water retention capacity of coarse rock fragments is usually considered negligible. But the presence of rock fragments in a soil can play an important role in both water holding capacity and in hydraulic conductivity as well. This paper presents results of maximum water holding capacity measured in coarse rock fragments in the soil classified as cobbly sandy loam sampled at High Tatra mountains. It is shown, that those coarse rock (granite) fragments have the maximum retention capacity up to 0.16 volumetric water content. Retention curves of the four particular granite fragments have shown water capacity available for plants expressed in units of volumetric water content of 0.005 to 0.072 in the soil water potential range (0, -0.3 MPa). Available water capacity of stone fragments can contribute to the available water capacity of soil fine earth considerably and help to plants to survive during dry spells.
