Sensitivity to hydrogen induced cracking, and corrosion performance of an API X65 pipeline steel in H2S containing environment: influence of heat treatment and its subsequent microstructural changes
(Peer reviewed; Journal article, 2021-07)In this investigation, the effect of microstructural changes and phase equilibria on corrosion behavior and hydrogen induced cracking (HIC) sensitivity of an API X65 pipeline steel was studied. For this purpose, heat ... -
Service and inventory model for maintenance workshop in the short cycle operation region: Agent-based simulation approach
(Peer reviewed; Journal article, 2023)Tools used in the North Sea region has a high cycle and come very often to maintenance workshop to be checked, repaired if needed and prepared for the next operations. The availability of spare parts at the workshop plays ... -
Servitization: A Model for the Transformation of Products into Services through a Utility-Driven Approach
(Journal article; Peer reviewed, 2018-12)The economies of the industrialized world have become dominated by services. Many manufacturing companies have changed from producing products to providing services. However, many companies still lag behind in this ... -
Short-Crested Wave–Current Forces on a Concentric System with an ARC Exterior Porous Wall
(Peer reviewed; Journal article, 2023-03)In this study, the potential flow theory is adopted to develop an analytical solution to the diffraction problem of a short-crested wave–current incident on a concentric system consisted of an arc exterior wall and interior ... -
Simulated wind-generated inertial oscillations compared to current measurements in the northern North Sea
(Journal article, 2018-06)Measured current speed data show that episodes of wind-generated inertial oscillations dominate the current conditions in parts of the northern North Sea. In order to acquire current data of sufficient duration for robust ... -
Simulation of peak tension loads in Subsea power cables during installation
(Peer reviewed; Journal article, 2021-11)At present, most of the insurance claims in the offshore wind industry are due to cable failures where a large percentage occurs during the installation of the array and export cables. As the reliability of the cables ... -
