A low-cost coastal buoy for ice and metocean measurements
Petrich, Christian; O'Sadnick, Megan Eileen; Kleven, Øystein; Sæther, Irina Vasiljeva (Peer reviewed; Journal article, 2019)Regionally, an ice cover in fjords of mainland Norway may form and break up repeatedly during winter. Due to relatively high water temperatures, the freeze-up process is expected to be related to freshwater-induced ... -
A Note on Remote Temperature Measurements with DS18B20 Digital Sensors
Petrich, Chris; Sæther, Irina Vasiljeva; Dang, Nga Phuong; Kleven, Øystein; O'Sadnick, Megan (Chapter, 2020)Digital temperature sensors provide an attractive means to conveniently record ice and water temperatures in remote locations. Unlike conventional analogue techniques, a digital sensor performs a physical measurement, ... -
Common solutions and challenges to the traverse of sea ice by ships
Petrich, Christian; Sæther, Irina Vasiljeva (Peer reviewed; Journal article, 2015)The specific challenges of ship operations in sea ice-covered waters of the Arctic depend on factors including the purpose of the operation, the capabilities of the ship and equipment available, the degree of situational ... -
Methods for prediction of thermally-induced ice loads on dams and hydro-electrical structures
Sæther, Irina Vasiljeva (Norut Narvik Report;19/2019, Research report, 2019) -
Static ice loads on a dam in a small Norwegian reservoir
Petrich, Chris; Sæther, Irina Vasiljeva; O'Sadnick, Megan; Arntsen, Bård (Chapter, 2020)Ice loads on a concrete dam have been calculated from stress measurements in Taraldsvikfossen Reservoir, a small reservoir in Narvik, Norway, during three winter seasons. Ice thickness was in the range of 0.5 to 1.0 m, and ... -
Time-dependent spatial distribution of thermal stresses in the ice cover of a small reservoir
Petrich, Christian; Sæther, Irina Vasiljeva; Lennart, Fransson; Sand, Bjørnar; Arntsen, Bård (Peer reviewed; Journal article, 2015)Static ice loads (ice actions) are a key design parameter for dams in cold climates. However, their theoretical description is still elusive, introducing uncertainty in design and hindering development of remediation ... -
Winter concreting full-scale field trial of rock tower foundations
Petrich, Christian; Sæther, Irina Vasiljeva; Arntsen, Bård (Lecture, 2018)Winter concreting can be an attractive option for construction in remote areas where concerns about wildlife and soil integrity are prioritized. In order to minimize disturbance of wildlife and to be able to access remote ...
