Abstract
Abstract Offshore oil and gas operations are inherently associated with risk and may have catastrophic consequences to life, property, and environment. Risk management is thus performed during the design, planning, and operation phases to control risk. Operational risk models are only periodically updated and do not always reflect the available real-time data. This is also the case for dynamic positioning (DP) operation. Monitoring the risk levels of the system during the operational phase could reduce the accident risk by providing additional decision support information for operators. In this paper, a framework for the risk management of DP operation is proposed to assist operators in decision-making. The risk management output will provide operators a real time risk status and pre-warnings of possible deviations in the system. This framework is developed to support the decision-making process of the operators with providing failure probability of alternative decision scenarios, and it can be applied to any other engineering system and operation. In order to validate the effectiveness of the framework, DP drilling operations are considered as a case study. The results demonstrate the value and effectiveness of the framework, which reduces the risk level of operations by contributing to the risk-informed decision-making of operators.

Abstract System health management based on condition monitoring is of great value and significance for improving system performance and reliability. As more data from condition monitoring is obtained, the efficiency of system health monitoring improves. However, increasing the amount of data by installing new sensors on system components is restricted by a variety of factors such as budget, weight and space allowance. Therefore, sensor selection in the most optimal manner in order to achieve max...

Abstract The design and function allocation of control in complex technological systems have mainly been technology-driven, resulting in increased automation. A human or user perspective is rarely taken in the technological development. The pertaining attitude seems to be that increased automation will reduce the occurrence of human error and thereby ensure safer design and operation. Increased levels of automation, however, may come with a cost of reduced situation awareness for the human opera...

Abstract Central heating system faults affect building energy consumption and indoor thermal comfort significantly. The interdependencies among system components and multiple failure modes present a challenge for system health diagnostics and prognostics. A reliable diagnosis and prognosis can only be ensured when all component conditions are monitored with minimum uncertainty. In this regard, sensors should be selected based on their priority in providing system health information. Currently, m...

Abstract Existing naval ships are often required to extend their service life due to budgetary constraints. This can incur significant costs associated with maintaining aged ships in operation. The risk of structural failure also rises during the extended service life if repairs are not performed. Repairing aging ships is often necessary in order to counteract the adverse impacts of aging and environmental stressors, such as corrosion and fatigue. Decision making on the repair of aging ships nee...

Abstract This paper's objective is to analyze the main real-time risks in operation of autonomous marine systems, which follow from various levels of autonomy (LoA). High reliability management (HRM) is an established framework for assessing real-time operator performance in complex infrastructures. In this paper, the framework is applied to two cases representing different uses and autonomy levels: one on marine underwater robotics focusing on remotely operated vehicles (ROVs) and subsea interv...

Oil pipeline network system health monitoring is important primarily due to the high cost of failure consequences. Optimal sensor selection helps provide more effective system health information from the perspective of economic and technical constraints. Optimization models confront different issues. For instance, many oil pipeline system performance models are inherently nonlinear, requiring nonlinear modelling. Optimization also confronts modeling uncertainties. Oil pipeline systems are among ...

Abstract Information visualization is a key component of many decision support tools in sciences and engineering. Graph is a visual construct that is widely used to model information for visualization. In this paper, a value-risk graph is proposed to visualize the results of value-risk based performance measurement systems (PMSs). The proposed graph for PMS divides the overall performance of industrial systems into distinct zones to facilitate the decision-making process. The upper bound, lower ...

Abstract A reliable Dynamic Positioning (DP) system is the key requirement for critical offshore activities. This paper presents the quantitative reliability assessment for offshore multi-megawatt capacity electric DP systems based on the present technological maturity and the offshore industry-reported component failure rates. It is identified that the International Maritime Organization defined DP1, DP2 DP3 architectures with fully redundant power generators and electric variable speed thruste...

Operational planning decisions, which are characterized by relatively short time lag between decision and implementation, have received little attention in risk and safety research in offshore oil and gas industry. The overarching objective of the paper is to find out how to provide good risk information for such decisions. The discussion starts from description of what good risk information is, followed by a proposal to use Activity consequence risk (ACR) – the effect that performing an activit...
