The Dynamic Behavior Of Mooring Lines
Offshore Technology Conference, 1977ABSTRACT In this paper the results are presented of ＿a model study into the behaviour of anchor lines as used in the offshore mooring of a wide variety of floating structures. For this study model tests have been carried out with a buoy moored to four chains. The effect of model scale, pre-tension in the lines, wave

Practical Estimation of Mooring Line Damping
Offshore Technology Conference, 1988ABSTRACT When predicting the resonant surge and sway motions of moored structures, it has until recently been customary to neglect the contribution from mooring line drag upon the system damping. In 1986 there was the first publication (OTC paper 5204) presenting a theoretical discussion of the effect, together with

Experimental Study of Polyester Mooring Lines
The Journal of Ocean, Mechanical and Aerospace -science and engineering- (JOMAse), 2017Mooring lines have several types of material which is chain, wire, synthetic fiber rope and hybrid. Mostly, in oil and gas industry is use chain and wire rope as a mooring line for shallow water platform. When exploitation of oil and gas become deep, synthetic fiber is use as an alternative for mooring line.

HMPE Mooring Lines for Deepwater MODUs
OTC Brasil, 2011Abstract Polyester synthetic mooring lines are used widely in deepwater moorings for MODU (Mobile Offshore Drilling Units). However, practical and technical limitations in the deployment of polyester tethers beyond water depths of 2,000m for short-term MODU moorings has prompted the development of alternative ...

Finite element modelling of mooring lines
Mathematics and Computers in Simulation, 2000In this paper, we develop a finite element model for a cable suspended in water. Global existence and uniqueness of solutions of the truncated system is shown for a slightly simplified equation describing the motion of a cable having negligible added mass and supported by fixed end-points. Based on this, along with well known results on local existence

The use of HMPE mooring lines in deepwater MODU mooring systems
OCEANS 2008, 2008The use of synthetic components, particularly polyester, in deepwater Mobile Offshore Drilling Units (MODUs) mooring systems has become a viable option to extend the mooring capabilities of a MODU. To date, the use of synthetic components in MODU moorings has mostly been limited to polyester, with few exceptions. This paper will focus on an alternative

Ensuring Mooring Line Safety for Deepwater Turret-Moored FPSO in Extreme Seas
Journal of Coastal Research, 2015ABSTRACT Wang, Y.; Dou, X.; Ding, F.; Tuo, Y., and Liu, Y., 2015. Ensuring mooring line safety for deepwater turret-moored FPSO in extreme seas. This study addresses dynamic positioning technology of deepwater FPSO moored to the seabed via a turret based spread mooring system, referred to as Position Mooring (PM).

Mooring Line Tensions Prediction Based on MLP for Soft Yoke Mooring System
Volume 5B: Ocean EngineeringAbstract 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.
