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...

Abstract The advent of autonomous cars, drones, and ships, the complexity of these systems is increasing, challenging risk analysis and risk mitigation, since the incorporation of software failures intro traditional risk analysis currently is difficult. Current methods that attempt software risk analysis, consider the interaction with hardware and software only superficially. These methods are often inconsistent regarding the level of analysis and cover often only selected software failures. Thi...

Abstract Advanced technological systems consist of a combination of hardware and software, and they are often operated or supervised by a human operator. Failures in software-intensive systems may be difficult to identify, analyze, and mitigate, owing to system complexity, system interactions, and cascading effects. Risk analysis of such systems is necessary to ensure safe operation. The traditional approach to risk analysis focuses on hardware failures and, to some extent, on human and organiza...

Abstract The objective of this paper is to outline a framework for online risk modelling for autonomous ships. There is a clear trend towards increased autonomy and intelligence in ships because it enables new functionality, as well as safer and more cost-efficient operations. Nevertheless, emerging risks are involved, related to lack of knowledge and operational experience with the autonomous systems, the dependency on complex software-based control systems, as well as a limited ability to veri...

Abstract In recent years, environmental protection has received more attention in society. In addition to the ecological effect of a hydrocarbon release into the sea, its environmental impact is assessed by considering the amount of pollutant discharged. Therefore, limiting the impact of a spill consists in lowering the volume of oil released and effective early detection is necessary for implementation of mitigating measures. Standards and guidelines have been established for developing effecti...

Abstract Maritime Autonomous Surface Ships (MASS) are the subject of a diversity of projects and some are in testing phase. MASS will probably include operators working in a shore control center (SCC), whose responsibilities may vary from supervision to remote control, according to Level of Autonomy (LoA) of the voyage. Moreover, MASS may operate with a dynamic LoA. The strong reliance on Human-Autonomous System collaboration and the dynamic LoA should be comprised on the analysis of MASS to ens...

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 This article presents a novel 2.5D map representation, termed polar map, that has a memory consumption of O(ML), where M and L depend on the map's angular and depth resolution, respectively. The map has a computational effort of O(1) in the update and evaluation process, where updates are performed through the use of Kalman filters. The representation can only be applied to structures in an environment that can be represented uniquely in a cylindrical coordinate system, such as fish cag...

Abstract Norwegian fish farms are expanding into more exposed sites due to a lack of sheltered coastal locations and growing negative ecological consequences close to land. The severe wave and current conditions, irregular and often high winds, sheer remoteness, and limited weather window amplify the hazards during aquaculture operations. This paper presents a methodology for identifying hazards in aquaculture operations that take into account risks to personnel, material assets, the environment...
