CFD simulation of long slender offshore structures at high Reynolds number
Slender cylindrical structures are common in many offshore engineering applications such as floating wind turbines and subsea risers. These structures are vulnerable to flow-induced vibrations under certain environmental conditions which impacts their useful life. Flow-induced vibrations have been …

Reliability analyses of the collapse and burst of elastic/plastic tubes
… Steel tubes have broad applications in petroleum offshore engineering and must be designed to a safe but yet economical standard. The variation of imperfections from tube to tube necessitates a statistical characterization in which the burst and collapse pressures become random variables. In order …

Real-time monitoring of cement sheath integrity under high-angle HPHT wellbore conditions.
… life of the wellbore. The results of a recent engineering study of 15,500 wellbores in the Gulf of Mexico show that, as a wellbore turns fifteen years of age, it develops a fifty percent chance of being adversely affected by sustained casing pressure. Even though a high percentage of the …

Development of an optimised integrated underbalanced drilling strategy for cuttings transport in gas-liquid flow through wellbore annuli.
Although understanding the relationship between gas-liquid two-phase fluid flows and the effects of the major drilling variables is critical to optimising underbalanced drilling (UBD) operations, to date, this has been an area of limited research and knowledge. This study contributes to the limited …

Long-term Cyclic Lateral Response and Optimisation of Shallow Foundations
… of capital expenditure for both onshore and offshore wind turbines. Current design methodologies for gravity-based foundations (GBFs) have limited capacity to predict long-term cyclic loads. This leads to conservative designs, excessive material use, and a higher carbon footprint. This thesis …
