Abstract The main objective of our ongoing research is data collection for integrity management (IM) tasks, in other words pipeline system (PIMS), helping the transporting operators different decision situations. Either reserves girth welds after a long-term operation can be identified or with defects should repaired and/or replaced. From operators’ point view, cost-effective way; however, from...

Abstract A new approach to anomaly detection termed “anomaly with designable generative adversarial network (Ano-DGAN)” is proposed, which a series connection of and network. The proposed Ano-DGAN, based on deep neural network, overcomes the limitations abnormal data collection when performing detection. In addition, it can perform statistical diagnosis by identifying healthy range each design ...

Dropped objects from cranes are one of the most hazardous events during the operation of the topside of offshore plants along with hydrocarbon gas explosion and fire. Although it is strongly suggested by international rules and regulations to evaluate probabilistic impact risk from dropped objects in the offshore industry, most engineers have had difficulties in estimating a reliable risk value...

Riser emergency shutdown valves (RESDVs) are an essential risk reduction measure for offshore installations and are a legal requirement under the Pipelines Safety Regulations 1996. The RESDV should isolate the topsides from the well and subsea pipeline in the event of an emergency shutdown, to reduce the inventory for loss of containment or when required for maintenance. RESDV failures, whether...

Fault Tree Analysis (FTA) as a Probabilistic Risk Assessment (PRA) method is used to identify basic causes leading to an undesired event, to represent logical relation of these basic causes in leading to the event, and finally to calculate the probability of occurrence of this event. To conduct a quantitative FTA, one needs a fault tree along with failure data of the Basic Events (BEs). Sometim...
