The accidents of subsea pipelines due to third-party interference often result in catastrophic impacts, therefore, risk assessment has progressively become substantial ensure the safety and reliability systems. However, current analysis approaches are unable minimize uncertainties high demands qualitative inputs. Bayesian network approach is believed be able provide answers such a problem. main...

During their service life, marine pipelines continually accumulate damage as a result of the action of various environmental forces. Clearly, the development of robust techniques for early damage detection is very important to avoid the possible occurrence of a disastrous structural failure. Most of vibration-based damage detection methods require the modal properties that are obtained from mea...

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...

Increasing demand on the performance of Subsea Production Systems (SPS) suggests a need for more detailed investigation of fluid behavior taking place in subsea equipment. Complete CFD cool down analyses of subsea equipment are very time demanding. The objective of this paper is to investigate a Locked CFD approach, which enables significant reduction of the computational time and at the same t...

Anti-slug control applied to two-phase flow provides a very challenging and important application for feedback control. It is important because it allows for operation that would otherwise be impossible, and challenging because of the presence of both RHP-poles and RHP-zeros. To conduct experiments on pipeline-riser anti-slug control, a small-scale slug-loop has been build. The loop has been mo...
