System reliability of an offshore power plant with several gas turbine engines is analyzed in this study to understand the failure intensity of a selected gas turbine engines under varying maintenance activities. A set of event data of a selected gas turbine engine is considered to identify system failure intensity levels, where unknown maintenance actions were implemented (i.e. various repairs ...

The Finnmark Platform Composite Tectono-Sedimentary Element (CTSE), located in the southern Barents Sea, is a northward-dipping monoclinal structural unit. It covers most of the southern Norwegian Barents Sea where it borders the Norwegian mainland. Except for the different age of basement, the CTSE extends eastwards into the Kola Monocline on the Russian part of the Barents Sea. <p> <p>The general ...

The role of the North Atlantic Treaty Organization and its influence on the peace and conflict dynamic in the Middle East has always been a discussed and controversial issue. While the United States and the countries of the NATO Southern flank are active in the discussions on NATO engagement in the region, the perspectives of NATO Eastern flank countries is often forgotten. This work contributes to ...

This article discusses critical infrastructure resilience in terms of how it could be incorporated into the existing safety and security practices, namely the ISO 31000 risk management standard. The article starts by outlining the resilience discourse, focusing on the organizational, technological, and societal domains of resilience. It goes on to present an approach to how the risk management ...

Floating glacial ice features of various sizes pose a substantial threat to the structural integrity of offshore structures in ice-prone regions. Relatively small ice feathers, e.g., bergy bits and growlers, are a major concern because they are more difficult to detect by marine radars and perform concurrent ice management operations, especially in extreme sea states.<p> <p>This two-part companion ...

In this paper, we present a new mixed-integer linear goal programming (MILGP) model for a fuzzy single-source capacitated facility location problem (F-SSCFLP), in which demands are considered as triangular fuzzy values and capacity of facilities are fuzzy constraints. At first, the basic fuzzy model for the given problem is presented. Then, utilizing goal programming (GP) approach and fuzzy principals ...

Unmanned Aerial Vehicles (UAV) technology has found its way into several civilian applications in the last 20 years, predominantly due to lower cost and tangible scientific improvements. In its application to structural bridge inspection, UAVs provide two main functions. The first, being the most common, detect damage through visual sensors. The 2 D image data can be used to quickly establish a basic ...

While concepts like risk and crisis management have grown ubiquitous at all levels of government, they have also cemented their place in academia as interdisciplinary fields of study in higher education. In the Baltic Sea Region (BSR), these types of educational programmes are typically labelled under the umbrella term ‘societal security’ in English. This article provides a succinct depiction ...

To be able to handle crisis and risks there is a need for different skills. We will focus on learning by combining theory and practice. Since NEEDS is a disaster management community, scenarios in line with this theme are wanted.<p> <p>This colloquium can be an experience transfer between educators that work with scenario-based training and want to develop this further. Drawing on different ...

The paper shows the possible implementation of an Infrared (IR) ice detection technique. In respect of safety in marine operations, saline ice detection can be significant for automated de-icing systems. Experimentation is performed to observe and detect saline and pure ice samples. The discussed detection mechanism is unique and differs from passive IR detection by introducing the self-heating ...
