Study on dynamic tension estimation for the underwater soft …
2023年1月1日 · Aiming to solve the trouble of tension monitoring about the underwater SYMS mooring leg, the LSTM-AM neural network model is proposed, which takes the FPSO 6-DOF motions and their first-order and second-order central moments as the input data series to estimate the mooring legs tension.

2024年2月25日 · This article takes the implementation of FPSO work cabin in Lufeng 12-3 oilfield as the background. By using AQWA software to establish FPSO and underwater detection device models， the...
2023年9月15日 · Under the external load, the dynamic responses of underwater production systems at moor-ing state have been a hot issue among scholars, for example, Wichers and Dev [1] derived the motion equations of FPSO and its mooring lines in time domain based on the conventional uncoupled theory.
The offshore dry-docking concept is based on lifting the FPSO out of the water by submerging the “Dockwise Vanguard” underneath the FPSO offshore without disconnecting it from its mooring system and leaving the flow lines connected.
This analysis will suggest the ultimate mooring configuration for the FPSO station keeping system. The criteria will also consider the costs involved, safety and operational elements. By comparing all the mooring configuration, the tension pattern can be defined in graphical method that can differentiate significant tension
Design, implementation and analysis of full coupled monitoring system …
2016年2月1日 · The training data collection is implemented with the numerical hydrodynamic coupled analysis of FPSO and an underwater soft yoke mooring system. Different variables are studied to determine the optimal structure of the LSTM-AM neural network model, including the time window, the layer numbers, the neural units and the optimizer.
Floating offshore structures, such as FPSOs coupled with mooring lines to the ocean floor (or seabed) experience forces and revolving moments caused by dynamic excitations from environmental elements such as wind, current and waves.
