Corrosion product film-induced stress facilitates stress corrosion cracking
(Journal article; Peer reviewed, 2015)Finite element analyses were conducted to clarify the role of corrosion product films (CPFs) in stress corrosion cracking (SCC). Flat and U-shaped edge-notched specimens were investigated in terms of the CPF-induced stress ... -
Corrosion properties of AA5083 and AA6082 in seawater - effect of temperature, pH and potential
(Master thesis, 2016)Aluminium is an interesting material for use in subsea structures due to its low weight. So called corrosion resistant aluminium alloys from the Al-Mg (5xxx)- and Al-Mg-Si (6xxx) series have been used for many years in ... -
Corrosion Properties of Stainless Steel in Stagnant Seawater
(Master thesis, 2020)Denne rapporten fokuserer på korrosjonsegenskapene til rustfritt stål i stillestående sjøvann i åpne og lukkede beholdere. I flere tiår har ulike legeringer av rustfritt stål blitt brukt i marint miljø på grunn av ... -
Corrosion Properties of Stainless Steels Exposed to Sodium Chloride and Small Addition of Fluoride
(Master thesis, 2019)Formålet med denne oppgaven var å undersøke hvilken effekt fluorider og klorider har på gropkorrosjon av ulike rustfrie stål. Denne rapporten vurderer kritiske faktorer som temperatur kombinert med ulik konsentrasjon av ... -
Corrosion protection of Mg-SiC nanocomposite through plasma electrolytic oxidation coating process
(Peer reviewed; Journal article, 2022)Understanding the role of nanoparticles in magnesium (Mg)-based materials and protective coating provides valuable information to achieve an optimized combination of mechanical and corrosion protection properties of Mg ... -
Corrosion protection of Mg-SiC nanocomposite through plasma electrolytic oxidation coating process

Corrosion Protection under Thermal Insulation
(Master thesis, 2013)Corrosion under insulation (CUI) is an extensive and costly problem for the petrochemical and chemical industry. Both good coatings to mitigate the problem and test methods to ensure the quality of these coatings are needed. ... -
Corrosion, hydrogen uptake and environmentally assisted cracking of flexible pipe steel armour wires
(Doctoral theses at NTNU;2022:159, Doctoral thesis, 2022)Flexible pipes are widely used in oil and gas applications. They consist of several metallic and polymeric layers, including a layer of tensile armour wires made from high-strength carbon steels. The armour wires are closely ... -
Corrosion-induced damages and failures of posttensioned bridges: A literature review
(Peer reviewed; Journal article, 2022)Corrosion of posttensioned bridges raises great concern, since the only way to safely assess the condition of the tendons is through destructive evaluation. In this scenario, this paper presents the results of an extensive ... -
Cost and Quality Consequences of Shortening the Project Life Cycle
(Master thesis, 2013)Shortening duration of project is a challenging task. If time is reduced with no attention is paid to additional risk, not only no time reduction is achieved but also it can exert counter effect by increasing the time, ... -
Cost and time overrun in road construction : Magnitude, Causes and Cost Estimating Models
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:207, Doctoral thesis, 2011)This study investigates the cost and time overrun in road construction projects in the West Bank in Palestine. The magnitude and causes of cost and time overrun are studied and recommendations to enhance the performance ... -
Cost effectiveness of higher thermal resistance in commercial buildings
(Master thesis, 2014)Using energy simulation software this report studies a typical Norwegian commercial buildings thermal energy loss. The buildings energy use is simulated and analyzed using SIMIEN, for four levels of thermal resistance in ... -
Cost Efficient Industrial Heat Recovery through Heat Pumps
(Master thesis, 2016)Industrial waste heat often contains large amounts of useable energy that cannot be utilized in its current form, and has to be used together with a waste heating technology to become useful. With increasing energy prices ... -
Cost Escalation in Road Construction Contracts
(Peer reviewed; Journal article, 2021)This paper presents a study of cost escalation in unit price road construction contracts. The aim is to investigate why the final cost of contracts differs from the agreed contract cost following tendering, both to identify ... -
Cost escalations in the front-end of projects – empirical evidence from Norwegian road projects
(Journal article; Peer reviewed, 2017)This paper investigates an issue largely ignored in the transport literature on cost overruns, namely, cost increases in the early project phase, long before the decision to build is made. This is the phase of project ... -
Cost Estimation of Construction Projects Using Case-based Reasoning (CBR) at Early Stage
(Master thesis, 2022)Sammendrag I bygg- og anleggsbransjen har kostnadsoverskridelser, forsinkelser i byggingen og lav kvalitet lenge vært vanlige utfordringer. Kostnadsestimering på et tidlig stadium av et byggeprosjekt er en av de vesentlige ... -
Cost evaluation and life cycle assessment of biogas upgrading technologies for an anaerobic digestion case study in the United States
