... and gain deeper insights into the behavior of marine risers subjected to varying environmental conditions. This intersection of offshore engineering and AI has led to the development of innovative solutions aimed at mitigating the impact of VIVs on marine risers. Abstract We developed and tested...

... in deep-water offshore environments. Low water column temperature in deep water along the marine riser can cool down the produced fluids considerably. This in turn can trigger hydrate formation introducing significant challenges to the operations while increasing the risk of HSE incidents and therefore...

... Abstract The application of CFD (Computational Fluid Dynamics) to the issue of vortex induced vibration (VIV) of marine risers is a rapidly developing area of engineering which offers the potential to improve design capability whilst reducing associated testing costs. However, the tools...

... Abstract Although marine riser for drilling operations is the industry standard, this process is more and more expensive in deeper water. Fifty years of technology development and study applied to marine riser do not alleviate the direct and associated expenses which increasingly impact...

... to an extent that a station keeping incident requiring disconnect of the marine riser should be no more frequent than once every ten years1. This data can be used to predict the frequency of DP station keeping incidents that could be encountered during well completion or intervention activities. Figure 1...

... of the field. To fully realize benefits of this technology, a second, less capable rig hoisting system is required. Also, while riser tensions are much lower than those imposed by standard marine risers, they are substantial, and many older rigs would require tensioning system upgrades. Technical challenges...

... modaldecomposition and a least-squares method to estimate the modal weights. Themain purpose of the work was to provide data for calibration of computerprograms for prediction of VIV. Examples of results are given. Introduction To design marine risers for use in deep waters it is important to be able topredict...

... Abstract The internal fluid dynamic and other conventional forces are described completely in the governing equation of the lateral vibration of a marine riser. The current scope of work is to determine the natural frequency and the mode shape of an undamped riser. With proper tension...

... ABSTRACT This paper reviews the design methodology of marine riser systems and the analysis performed to substantiate the design corresponding to two field conditions in deep and shallow water. The analytical and numerical tools adopted are capable of handling riser dynamic analysis for cases...

... ABSTRACT A study of the vertical dynamics of marine riser-load systems has been performed to determine the amplitude of dynamic forces and displacements caused by heave action. The analysis predicts circumstances under which slackening or compression, and subsequent failure of a riser can...

... involved. Many riser simulations are purely two-dimensional but experimental data, such as that presented here shows that a uni-directional wave input does not result in a uni-directional response. Vortex shedding effects are a significant result of wave loading on a marine riser. THE TEST PROGRAM...

... Abstract Syntactic foam is a high-strength composite of plastic, fiberglass, and tiny hollow glass micro spheres. Because it is both strong and light, syntactic foam is frequently used to provide deep-sea buoyancy and is the preferred method of supporting marine risers in drilling beyond...
