Cross-acceptance of fire safety systems based on SIL equivalence in relation to IEC 61508 and EN 50129
Okoh, Peter; Dong, Hyunsoo; Liu, Yiliu (Peer reviewed; Journal article, 2022)Several sectors, e.g. process, railway, etc., have set their functional safety standards based on the generic IEC 61508. Yet, a product that is originally developed based on IEC 61508 is not automatically accepted for use ... -
Data-driven approaches for identifying risk factors in indoor environment during a surgery
Kazemitalachi, Tina (Master thesis, 2022)Surgical site infection (SSI) is one of the common complications after surgeries. It results in various consequences, from additional treatment to morbidity and mortality. Therefore, it increases the probability and duration ... -
Design and verification of a SIL-rated shutdown function for a subsea power grid
Zhitkova, Ekaterina (Master thesis, 2015)The offshore oil and gas industry is moving towards a direction where more and more process equipment are being placed subsea. Accordingly, various electrical equipment, including pumps, separators, gas compressors, water ... -
Design optimization of small fishing vessel structures: A case study
Putra, Gerry; Rizqillah, F; Yatim, Ardi; Liu, Yiliu (Peer reviewed; Journal article, 2023)The cost of vessel operations poses a significant challenge for fishermen in Indonesia, with 60% - 70% of their operational expenses being allocated to fuel. To address this issue and decrease fuel consumption in fishing ... -
