Relationships Between Build Location and PSV Shipbuilding Times
(Master thesis, 2023)Industrien for spesialisert skipsbygging leter kontinuerlig etter måter å forbedre konkurranseevnen på i form av kostnadseffektivitet og reduserte produksjons- og leveringstider. Det er likevel behov for mer forskning for ... -
Reliability Allocation and Assessment of Safety-Instrumented Systems
(Master thesis, 2014)Safety-instrumented systems (SISs) are technical systems that are used to protect humans, the environment, or assets from hazardous events. It is therefore important to ensure that these SISs are reliable. \citeauthor{61508} ... -
Reliability Analysis for Physically Separated Redundant System
(Chapter, 2017)Redundancy has been a key concept to achieve high system reliability in technical systems, and the concept is central in modern technology regulations. One important aspect of successful redundancy is independence of the ... -
Reliability Analysis of Wireless Safety-Instrumented Systems
(Master thesis, 2015)Progressive development of wireless technology in recent years has enabled it to span its application to a wide verity of systems. Simple house hold monitoring and monitoring of a patient in a hospital gives two diverse ... -
Reliability and barrier assessment of series–parallel systems subject to cascading failures
(Peer reviewed; Journal article, 2020)Cascading failures can occur in many technical systems where the components are organized as in series–parallel structures. The failures in these systems may propagate from one component to the other, not only within the ... -
Reliability and Safety Assessment of All-Electric Subsea Concepts
(Master thesis, 2019)Olje- og gassindustrien ønsker å erstatte eksisterende elektrohydrauliske styringssystemer med hel-elektriske løsninger for kontroll av undervannsventiler. Hel-elektrisk teknologi har stort potensial for utnyttelse av ... -
Reliability and safety assessment of Asubsea rov-based sensor retrieval tool
(Master thesis, 2011)The ROV –based subsea sensor retrieval system is a new technology designed by RoxarFlow Measurement As, for the installation and retrieval of subsea sensors mounted on subsea production equipment (such as Christmas trees ... -
Reliability assessment for final elements of SISs with time dependent failures
(Journal article, 2018)Reliability assessment for safety-instrumented systems (SISs) plays a vital role in improving the design of SISs. Traditional methods for SIS reliability assessment that assume constant failure rates are, however, not ... -
Reliability assessment for subsea HIPPS valves with partial stroke testing
(Chapter, 2017)High integrity pressure protection systems (HIPPS) have been applied in subsea applications to prevent accidents due to over-pressurization. A subsea HIPPS can be regarded as a complete functional loop consisting of sensors, ... -
RELIABILITY ASSESSMENT OF A SUBSEA HIPPS
(Master thesis, 2014)Safety instrumented systems are vital in the oil and gas industry. A SIS consists of input elements, a logic solver and final elements. A High Integrity Pressure Protection System is an example of such a system. HIPPS is ... -
Reliability assessment of safety instrumented systems operating in high demand mode
(Master thesis, 2010)Safety instrumented systems (SISs) play an important role in protecting human life, the environment, and material and financial assets. In order to achieve the expected protection function, high reliability of such systems ... -
