Dynamic Analysis Of Offshore Structures
… and appears to be small. (3) Response of Fixed Offshore Towers to Random Wave Forces Accounting for Pile-Soil-Pile Interaction. Dynamic pile-soil-pile interaction under the effect of wave forces is usually neglected in the design of offshore towers. It is examined and found to have a significant …

Some aspects of the analysis of offshore structures
… the presence of another.<br/><br/>The principal structures considered here are idealised as plane framed structures (though the theory is applicable for structures with, say, plate elements also), and in this connection wave forces on inclined frame members are considered. This is particularly …

THE EFFECTS OF CURRENT BLOCKAGE ON OFFSHORE STRUCTURES
… of hydrodynamic forces on fixed space-frame structures in combined waves and an in-line steady current. Because of current blockage, the actual drag force experienced by such structures is over-predicted by the standard Morison equation and the present industry standard practice. A set of …

Uncertainty quantification in the dynamic analysis of offshore structures
… with structural dynamics, especially in the offshore environment. Deterministic solutions are often insufficient to achieve confidence in computational results and for use in design. In uncertainty quantification (UQ) for problems dealing with many random or stochastic sources, surrogate …

Marine growth and the hydrodynamic loading of offshore structures
… of marine growth on the hydrodynamic loading of offshore structures and proposes an approach that can be adopted by designers and operators to quantify these effects. The approach is based upon the realistic characterisation of marine growth and its temporal variations during the life span of …

Navigation and manipulation for autonomous underwater dismantling of offshore structures
The dismantling of offshore structures, known as decommissioning, is a complex task in the oil and gas industry, driven by strict environmental standards. As the environments in which decommissioning is necessary become more challenging, autonomy presents itself as a solution to conduct this work …

Time-domain second-order wave interactions with floating offshore structures
… load and response predictions for large floating structures subjected to steep waves. With the increasing need to incorporate more accurate analyses of wave effects into existing offshore design procedures, the emphasis of recent hydrodynamic research has been on the development of numerical …

Multichannel maximum entropy method of spectral analysis applied to offshore structures
… developed and applied in the dynamic analysis of offshore structures. Two different algorithms are implemented and compared with the conventional Blackman-Tukey method. These are (1) a direct on the data or Burg method and (2) a Yule-Walker or correlation function extension method. Cross-spectral …

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 …

An integrated approach to fatigue cracking, reliability and inspection of offshore structures
… fatigue cracking, reliability and inspection of offshore structures. The basis of the approach is statistical in nature and draws on recent experimental data and field measurements. It is intended as a working tool for those engaged in design, structural appraisal and sub-sea inspection of steel …

Analysis of the structural behaviour of grouted pile/sleeve connections for offshore structures
Existing experimental results are studied to determine the factors (including those not previously identified) affecting the strength of grouted connections. The current bond strength formula is evaluated and its limitations noted. Previous analytical work is examined and strengths and weaknesses …
