The pumping system is modelled as shown in Figure 3. Please note that it is an advantage to limit the size of the model by leaving out components which are not active in the sequences that we will be looking at. This is because all of the elements included in a model are included in the calculations, taking up part of our computer’s capacity. This is also the case for passive components such as...

The pipeline spanning is triggered by the unevenness of seabed. cyclic fatigue loadings from subsequent scouring make be prone to failure which can cause loss integrity and even catastrophic accident. However, probabilistic modeling a free subsea challenging task due its dynamic characteristics uncertain information. This paper proposes methodology that could capture uncertainty time dependence...

Data sharing with multiple parties over a third-party distribution framework requires that both data integrity and confidentiality be assured. One of the most widely used data organization structures is the tree structure. When such structures encode sensitive information (such as in the XML documents), it is crucial that integrity and confidentiality be assured not only for the content, but al...

The complexity of corrosion mechanisms in harsh offshore environments poses safety and integrity challenges to oil gas operations. Exploring the unstable interactions complex required an advanced probabilistic model. current study presents development a approach for consequence-based assessment subsea pipelines exposed mechanisms. Bayesian Probabilistic Network (BPN) is applied structurally lea...

Festoon links are single span subsea links that require no electrically powered amplifiers. Providing longer reach on these types of links enables cost effective, high bandwidth connectivity to more remote locations. TCM-QPSK is an innovative modulation format that works with the hard FEC generation of line cards to provide 2.0dB of extended reach on festoon links compared to differentially cod...

By design, the operation of a large 3MW permanent magnet motor-driven pump system has the potential to improve system efficiency and reliability to lower operator costs. Subsea electrical system design and motor performance must be predictable and validated prior to deployment. Critical elements of this system include successful remote start-up and step up–step down transformers. A number of di...
