Formulation of Enhanced Water-Glycol Lubricants for Offshore Components - The Influence of Thickeners in Environmentally Acceptable Lubricants on the Wear of a Steel Piston Cylinder
Iversen, Jostein (Master thesis, 2016)The service life of offshore stainless steel cylinders used for riser tensioner systems is lower than expected. This is due to the complex degradation mechanisms, like corrosion, wear and fatigue, that take place under the ... -
Investigating Protein Adsorption on Hydrophobic and Hydrophilic Polymers for Antifouling Coatings
Stokka, Solveig (Master thesis, 2023)Når overflater befinner seg i sjøvann vil ulike organismer fra sjøen adsorberes på overflaten. Dette fenomenet kalles marin begroing, og har vært et problem i årtusener. Første trinn i prosessen er typisk adsorpsjon av ... -
Statistical Analysis of Paint Ingredients' Effect on Hydrophobicity and Surface Roughness - Using the Power Spectral Density Function to Quantify Roughness
Aas, Vilde Emilie (Master thesis, 2022)Siden globale temperaturer øker grunnet drivhusgassutslipp og drivstoffpriser fortsetter å heves, er skipsindustrien på jakt etter en måte å minske drivstofforbruket. En forslått løsning er luftsmøringssystemer som pumper ... -
Tribological Behavior of Polymer Seal Materials in Water-Based Hydraulic Fluids
Bernat, Szymon Czeslaw; Brink, Angelika; lucas, melodia; Espallargas, Nuria (Journal article; Peer reviewed, 2018)In this work, two polymer materials have been tested in a lubricated reciprocating pin-on-plate contact geometry using water-based hydraulic fluids to simulate sliding conditions of seal materials used in offshore equipment. ... -
Tribological Testing of Environmentally Acceptable Lubricants for Maritime Applications
Moholt, Harald (Master thesis, 2016)In marine applications, such as ship stabilizers, manoeuvring or propulsion systems, a number of mechanical components are situated below the waterline. Due to negative effects of lubricant leakage in marine environments, ...
