Probabilistic evaluation of dynamic positioning operability with a Quasi-Monte Carlo approach

Brodogradnja
During the design phase of an offshore unit, estimating the station-keeping capabilities of the dynamic positioning (DP) system is mandatory. This means, in conventional offshore applications, to determine the maximum sustainable wind speed as a function

Safety Analysis on Drilling Riser-wellhead System in Drilling Ship Drift-off Condition

Shiyou jixie, 2017
The warning circle of the conventional drilling platform is determined by static analysis, which is a static analysis method that does not take into account the trajectory of the platform under the load of wind, wave and current, and cannot determine the

Indoor Dynamic Positioning Method Exploiting Passive RFID System

IEEE Access
In this paper, we propose a novel method for dynamic positioning using a single passive RFID tag to obtain its position through phase. This method addresses the phase integer ambiguity by introducing a robust phase unwrapping algorithm, solves the ...
