FPSO Risk Assessment and Acceptance Criteria With Application to FPSO Mooring Systems [PDF]

Volume 2: Structures, Safety and Reliability, 2009
Risk based design code safety format calibration for FPSO installations is addressed based on the results of a recent industrial project performed for IMP by the authors. Generic risk models for general engineering systems are introduced taking basis in recent work by the Joint Committee on Structural Safety (JCSS). Thereafter, the scenarios considered

Dynamical Sliding Mode Control for Robust Dynamic Positioning Systems of FPSO Vessels

Journal of Marine Science and Engineering, 2022
The conventional proportional derivative (PD) control algorithm with appropriate gain scheduling is generally applied to a dynamic positioning (DP) system. However, finding appropriate gains through gain scheduling makes the DP system more complicated. A
