...-makers can employ advanced approaches to address this problem, such as the multi-criterion decision analysis presented in this work. This methodology improves the decision-making process by ranking the various options for decommissioning subsea oil and gas assets. The model considers six criteria: Safety...

.... The proposed method is designed to infer the slip status with hookload, standpipe pressure (SPPA), and surface torque (STOR) sensor data. Specifically, the logic using hookload includes two criteria, a hookload standard deviation criterion and a dynamic hookload threshold criterion. This allows addressing...
