Methodologies for Reliability and Functional Safety Assessment of Offshore Systems

Abstract Reliability, Availability, Maintainability and Safety are the key requirements for the systems designed to operate in challenging marine environments. Unsafe operations lead to human risk and environmental damages, and equipment unavailability leads to economic losses. Hence, marine statutory and regulatory agencies recommend carrying out reliability and functional safety assessment during system engineering and operational phases of the project as well as implementing technical solutions so that the risks are reduced as low as reasonably practicable. This paper presents an overview of the scientific methodologies for determining the system design reliability and assessing the human factors, operational dependability, and safety of time-critical offshore systems.
