There are various energy efficiency and emission reduction regulations enforced by the national and international maritime authorities for the shipping industry to adopt greener technologies. In this light, LNG-fueled vessels can be a promising alternative for ocean going diesel operated ships. It will be more beneficial if the price of LNG is lower than diesel to make that an economically viable ...

States are security-seekers vis-a-vis ‘significant others’ who are cast as enemies in the international system. Usually, the study of the enemy image is connected with relative equilibrium concerning power capabilities. Less attention was given to a situation of a decisive power imbalance. Thus, a question arises whether such a situation will lead to a uniform enemy image? Concomitantly, what is the ...

Increased and enhanced utilisation of remote sensing and robotics in the Arctic can further enhance cultural safety and well-being and reduce the risks posed to archaeologists, heritage workers and others in the field. In this preliminary scoping survey, the authors review the current use of these technologies and consider a range of related issues, from cultural safety to nefarious use by criminals. ...

The leaching of heavy metals from tailings deposit due to the oxidation of sulphidic tailings and formation of acidic leachate is considered a high risk to the surrounding environment. Temperature plays an important role in the leaching of heavy metals from tailings in changing acid-based environment, especially in the Arctic area. To investigate how the temperature variation affected metal release ...

The cold environment in polar regions introduces additional challenges when abandoning passenger vessels and offshore facilities. The International Maritime Organization Polar Code requires vessels operating in polar regions to be equipped with approved thermal protective immersion suits (TPIS) that can be donned unassisted within 120 s. As time is critical during an evacuation, quantifying the Net ...

The machine learning approach is a new hot topic in recent years that are widely used in different sections, including industries, economy, disaster prediction and politics. After decades’ of development, the available machine learning algorithms are numerous and diverse. Traditional methods such as regression, classical statistical methods, are unfortunately laid aside as non-mainstream. This paper ...

The new Polish military branch, the Territorial Defense Force (TDF), has been described both as a defensive tool against Russian hybrid warfare and as a private paramilitary force of the incumbent Law and Justice Party. This paper examines the strategic, political, and military purposes of the Territorial Defense Force using two theoretical models. One is designed for analyzing units intended to ...

Modern land-based tourism in Longyearbyen had its beginning in the early 90s, but ships with tourists visiting Svalbard can be traced back as far as 1807. Over the past 20 years, the interest in Svalbard as a tourist destination has increased significantly, which has led to a rapid increase in the number of visitors. This relatively young industry have had to constantly adapt to this increased number ...

The hazards associated with ice accretion primarily due to impinging freezing sea spray on ship structures are considered among serious safety concerns for ships operating in the colder regions. An accurate sea-spray icing-estimation model to evaluate the ice accumulation during operations in these regions can make marine operations safer. The accuracy of the present icing models for estimating icing ...

In this paper we analyse how a municipality set out to integrate risk management throughout an organisation with more than 9000 employees in six divisions and over 100 sub-units. An objective was to ensure coherence in risk management related work conducted in various sub-units in the municipality. Being forerunners, those involved had to find their own way. We identify three focus areas of importance ...
