At terminals exposed to waves, the first-order wave-induced vessel motions can cause very high mooring line load ranges and peak tensions which can result in excessive mooring line fatigue and breakouts. These effects can be alleviated by proper selection of fiber rope materials and lengths for mooring lines and tails.

Lightweight Materials for Mooring Lines of Deepwater Tension Leg Platforms
Marine Technology and SNAME News, 1984The design of a mooring system for tension leg platforms (TLPs) becomes more complicated as water depth increases. The use of steel mooring lines requires complicated tensioning, handling, and flotation systems. This paper discusses the basic design requirements for the TLP mooring system and identifies several advanced fiber-reinforced lightweight ...

Wind/Wave Misalignment Effects on Mooring Line Tensions for a Spar Buoy Wind Turbine
Volume 1: Offshore Technology, 2018The design methodology for mooring systems for a spar buoy wind turbine considers the influence of extreme events and wind/wave misalignments occurring in its lifetime. Therefore, the variety of wind and wave directions affects over the seakeeping and as a result the evaluation of the maxima loads acting on the spar-buoy wind turbine. In

Abstract A moored ship can experience problems when subjected to heavy environmental loads. In most cases, wind and current loads are the only design considerations for the mooring situation in the harbor, and wave loads are not considered due to the low wave amplitudes in harbors.

Abstract This paper is to investigate the applicable probability density functions (PDFs) for the short- and long-term mooring line tension amplitudes to be used for accurately assessing the mooring line fatigue damage with the spectral method. Statistical characteristics of the mooring line tensions were investigated, in which kurtosis and skewness ...

Prediction of Mooring Line Tensions for Hurricane Conditions in the Gulf of Mexico
Volume 4A: Structures, Safety and Reliability, 2014A probabilistic metocean model for hurricane conditions is briefly described. The model is based on site-specific, hindcast data and defines the time variation of the metocean conditions during the realisation of a hurricane at the site. The annual extreme value distribution of mooring line tension for a large, semi-submersible, mobile drilling unit is

Dynamic tension in risers and mooring lines: an algebraic approximation for harmonic excitation
Applied Ocean Research, 2001A riser or mooring line, when excited dynamically at its upper end, resists the imposed displacement by increasing its tension. Viscous damping in the lateral motion is known to be crucial and the resulting problem is thus intrinsically nonlinear. In this paper, an algebraic expression for the dynamic tension, formerly obtained [Polar Engineers, ISOPE'-

Abstract An understanding of the interaction between extreme ocean conditions and floating offshore platforms is required for their design and safe operation. Rogue wave impacts cannot easily be handled by traditional analytic or computational techniques. Here we use Smoothed Particle Hydrodynamics (SPH) to simulate the fully non-linear dynamics of a
