Ice Detection Experimentation Setup Using Infrared and Active Heating
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-24)
The paper shows the possible implementation of Infrared (IR) ice detection technique. The experimental setup is implemented keeping in view of the marine icing phenomena over the ships and offshore structures. The detection mechanism is unique from the passive IR detection by introducing the active heating concept. The intervention of the active heating information inside the IR ice detection system ...
Modelled and observed sea-spray icing in Arctic-Norwegian waters
(Peer reviewed, 2016-11-15)
Hazardous marine icing is a major concern for ships operating in Arctic waters during freezing conditions. Sea spray generated by the interaction between a ship and ocean waves is the most important water source in these dangerous icing events. Although there exist several data sets with observations of ice accretion in conjunction with meteorological and oceanographic parameters, these data sets ...
Review of marine icing and anti-/de-icing systems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-17)
The aim of this work is to review the phenomenon of icing in marine operations. The focus is on two main sources of icing, namely atmospheric and sea spray. The literature reveals that sea spray icing is the main contributor to marine icing. This work discusses the available ice accretion prediction models on ships and offshore structures. It also reviews the anti-/de-icing technologies that can be ...
Measuring Thickness of Marine Ice Using IR Thermography
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-04)
<p>There are several challenges to operating in a cold climate. Marine icing is one of them, and its mitigation is vital for marine operations.</p> <p>The presented work is a laboratory-scale setup to measure marine ice thickness. The developed methodology can be applied towards de-/anti-icing setups. The method described is based on measuring the average surface temperatures of the marine ice. ...
Influence of local and regional air pollution on atmospheric measurements in Ny-Ålesund
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
The Zeppelin observatory is a research station near the village Ny-Ålesund in Svalbard. The facility delivers data to international projects devoted to high data quality monitoring of the background air pollution in the Arctic. An approach for quantifying the influence of local and regional pollution on measurements that may be misinterpreted as long-range transported one, is presented here. The ...
