Condition monitoring for subsea processing plant
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)Subsea implies unmanned work, harsh environmental conditions for the equipment operation and access difficulties in case maintenance or repair is necessary. Therefore operational conditions of subsea equipment should be ... -
Condition monitoring in Integrated Operation (IO)
(Masteroppgave/UIS-TN-IKM/2009, Master thesis, 2009)Outsourcing and remote monitoring are major industrial trends that provide an ideal platform for operators to focus and improve their core activities while saving cost. These trends have led to technological ... -
Condition-based maintenance of wind turbine blades
(Master thesis, 2022)The blades of offshore wind farms (OWTs) are susceptible to a wide variety of diverse sources of damage. Internal impacts are caused primarily by structure deterioration, so even though outer consequences are the consequence ... -
Conditional monitoring and operational management of a subsea production system
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)There is an identified need for mid-level systems for monitoring a large number of subsea wells. To meet this demand Statoil is looking into developing a software program for such monitoring. As a step in this process, ... -

Contact stresses associated with the wedge-lock mechanism in a prototype subsea pipeline recovery tool
(Peer reviewed; Journal article, 2019)This paper examines the contact stresses associated with the wedge-lock mechanism in a prototype subsea pipeline recovery tool (PRT) through numerical methods and experimental testing. The prototype PRT studied combines ... -
Contact temperature analysis of the classical Geneva mechanism through numerical methods
(Peer reviewed; Journal article, 2022)In this study, the flash temperature of the classical Geneva mechanism has been studied using the numer- ical method. An excessive sliding motion between the wheel and pin leads to the generation of heat at the contact ... -
Context analysis of Offshore Fish Farming
(Peer reviewed; Journal article, 2019-11)The in-land and nearshore fish farming is facing capacity limitation and onshore push-out regulations. Huge technological innovations are rapidly evolving toward developing competitive Offshore fish farming. These technological ... -
