Transient tension measurements during mooring deployments

Oceans '97. MTS/IEEE Conference Proceedings, 2002
Tensions recorded during the deployment of subsurface moorings using the "buoy first" technique demonstrate that transient peaks in tension occur which exceed the tension measured during the steady state descent of the mooring to the bottom. These tension peaks occur just after anchor impact, when the main float overshoots and then oscillates ...

Mooring Line Tensions Prediction Based on MLP for Soft Yoke Mooring System

Volume 5B: Ocean Engineering
Abstract The soft yoke mooring system is widely used for the floating production storage and offloading (FPSO) in shallow water. However, there were accidents of mooring system being pulled down by the FPSO in field. It is hence necessary to conduct realtime prediction of mooring line tensions.

Simulation Calculation of Mooring Tension of the Ship-Based Helicopter

2009 International Forum on Information Technology and Applications, 2009
The helicopter on the ship deck must be moored due to the impact of winds and waves. The forces of the ship-based helicopter are analyzed comprehensively and the expression of inertial acceleration from the movement of ship is derived. The mooring cable is a nonlinear flexible body and is handled by the finite element method instead of the equivalent ...

Tension/Torsion Behavior of Deepwater Synthetic Mooring Lines

Offshore Technology Conference, 2006
Abstract Synthetic fiber ropes are now being used in mooring systems off Brazil and in the Gulf of Mexico, and are being considered for deepwater handling applications. Their behavior under tension loads is well understood but induced torsion effects have received less attention. This paper presents tests to measure

Tension In A Taut Line Mooring; Frequency Domain Analysis

Offshore Technology Conference, 1974
ABSTRACT The random response of a taut line mooring excited by sea waves is treated in this paper. For analytical convenience, mooring line tension is divided into a deterministic quasi-static component and a random dynamic component.
