Simulation of Mooring Lines Based on Position-Based Dynamics Method [PDF]
IEEE Access, 2019 The Position-Based Dynamics (PBD) method considers the rope as a series of particles in rope simulation. This paper introduces the PBD method and simulates mooring line in ship mooring simulation training system with four constraints, which are distance ...

Journal of Marine Science and Engineering, 2023 The conventional mooring positioning technique is cost-effective; however, it shows poor maneuverability and positioning precision. In this study, to calculate the mooring tension, mooring cables were discretized into lumped mass models using the lumped ...

Grid-Based Set Point Generation Strategy for Position Control of Dynamic Positioning Assisted Mooring System [PDF]
한국해양공학회지, 2019 Unlike typical a dynamic positioning (DP) system, a DP-assisted mooring system must determine a set point (SP) that can ensure a mooring tension safety range to prevent an excessive increase in mooring tension.

Mooring system diagnosis and structural reliability control for position moored vessels [PDF]
Control Engineering Practice, 2015 Abstract Early diagnosis and fault-tolerant control are essential for safe operation of floating platforms where mooring systems maintain vessel position and must withstand environmental loads. This paper considers two critical faults, line breakage and loss of a buoyancy element and employs vector statistical change detection for timely diagnosis of

DP and the Art of Perfect Positioning [PDF]
Modeling, Identification and Control, 2022 How does a vessel keep its position at sea without mooring? The answer is through dynamic positioning, or DP. Advanced technology, combining position reference sensors, computers, propellers and thrusters, is used to counteract environmental forces such ...
