... Strength Ratio (RSR), is a gauge of the robustness and redundancy inhibited in a fixed offshore structure. It is very useful in being an indicator for fitness-for-purpose of the platform and which is an integral part of Structural Integrity Management (SIM). However, a typical deterministic ultimate...

... Abstract This paper presents a digitized Technical Limits Weight Control (TLWC) tool for integrity management of existing fixed offshore structures. The tool is currently integrated into PETRONAS's Structural Integrity Compliance System (SICS), which is a web-based application for Structural...

...-based monitoring system deployed in a marine and offshore structure could form a cornerstone for a structural digital twin. Sensor-based structural health monitoring requires the installation of hardware and software onboard the asset and may also involve integration and interconnection with existing...

..., Malaysia (2015). To ensure the safety of its offshore facilities, PETRONAS has appointed D'Appolonia to conduct a Probabilistic Site Hazard Assessment, PSHA study post Acheh earthquake to determine the earthquake spectral response value to be used for its offshore structures design. Due to the perception...

... Abstract Because noise issues onboard marine and offshore structures can adversely affect the performance and health of crew members, the subject has gained increasing attention in recent years. Noise analysis is necessary to improve acoustic design and mitigate inappropriate noise...

... to predict efficiently the probability of deck-slamming occurence for offshore structures. The present approach is based on the assumption of potential flow up to the second order and has four steps: representing relative wave elevation as two-term Volterra series, solving the eigenvalue problem, formulating...

... Abstract In this study, advanced numerical CFD tools based on OpenFOAM are developed to generate extreme waves for the investigation of wave-in-deck loads on fixed offshore structures. The numerical method employs a Navier-Stokes solver with the free-surface captured by the volume of fluid (VOF...

... Abstract The demand to perform structural integrity review and life extension for existing fixed offshore structures is increasing in order to support the changes arising from new technologies for production enhancement, in-service deteriorating conditions and regulatory requirements on ageing...

... Abstract Nonlinear dynamic response of offshore structures under seismic loading is a challenging and interesting problem to structural engineers. Fixed offshore platform under intensive ground shaking may undergo deformations well into the inelastic range. The first part of this paper...

... Abstract As the development of offshore oil well advances to deep sea, the platform/mooring lines coupled analysis in time-domain is required in estimating the design tension to consider the complex nonlinear effects in the dynamic responses of floating offshore structures. However...

... Abstract Berthing is a common marine operation frequently occuring in harbors and at open sea. It involves a moving vessel closely approaching a moored offshore structure or a pier from a far distance. During the berthing operation, the distance between the stationary structure and berthing...

... Abstract Motion analysis of offshore structures in close vicinity is critical for safe and effective operation. The objective of this article is to study the hydrodynamic motion of TLP and semisubmersible in close vicinity both experimentally and numerically. For experimental study, model tests...

... described in this paper provides a more realistic determination of the structural response of the modelled platform. The results obtained have major implications for both the design and assessment of offshore structures. An increased lateral soil stiffness will largely eliminate the foundation failures...

... of an offshore structure. In this work, we proposed a hybrid numerical scour model which estimates the equilibrium scour depth around a structure by utilizing hydrodynamic turbulence models to obtain key flow parameters and an optimization function to predict the equilibrium scour depth. It was demonstrated...

... There is an ever increasing need to extend the life of aging offshore structures beyond their original design life. Whether these structures are fixed offshore rigs or floating facilities, operators are continually looking for new inspection and mitigation techniques aimed at ensuring...

... There are increasing numbers of ageing offshore structures in the water of South China Sea which come along with various types underwater structure anomaly, such as joint crack, member flooding, shallow gas and subsidence. This phenomenon brings an immediate attention to the Asset Owner...
