... ABSTRACT The polyester rope has been widely used for the deep-water mooring system, for the advantages of excellent tensile strength, strong corrosion resistance, good fatigue property and low cost. To reduce the mooring cost and improve the mooring mechanical properties, this paper combines...

... for catenary mooring systems due to theirs excellent properties such as higher mooring stiffness, smaller footprint and higher platform payload. Polyester ropes are commonly applied to the deepwater taut-wire mooring system (TMS). However, polyester ropes may not provide enough stiffness to maintain acceptable...

... experimental results. INTRODUCTION Polyester mooring lines are commonly used at deep-water locations for a FPSO. Recommended way to describe dynamics of FPSO is to set a coupled model that also contains dynamics of mooring system. Breaking point of a polyester rope can be found at 15% elongation. Such high...

..., smaller footprint reduces clash risks with subsea and other installations in the vicinity, although the volume required to store polyester ropes on an anchor handling vessel is large, lightweight is an added value during mobilization and installation, fairlead tensions are moderate, therefore...

... ABSTRACT The ELF CONGO and SEI-)CO FOREX have just completed a 7 month trial of a large diameter polyester rope in deep water offshore Congo. The 500m long, 500 tons MBL, polyester rope was installed in December 1997 on the SEDCO $700 semi-submersible drilling rig, anchored in more than 800m...

... ABSTRACT: This paper presents some of the findings from an investigation into the heat build-up and mechanical property behaviour of full scale polyester rope. Limited data is also presented on a full scale Kevlar rope. All of the tests were carried out with the rope samples fully immersed...

... ABSTRACT The use of synthetic fibre ropes in offshore rig and platform mooring is becoming increasingly likely. A leading candidate fibre is polyester since it has an excellent blend of properties. Like other fibre ropes, polyester ropes have low weight compared to steel and their consequent...

... system using polyester ropes is significantly more cost effective than a conventional catenary mooring system at large water depths. As an overall conclusion the investigation has confirmed satisfactory behavior of the proposed TMS concept. Keywords: Deep water, Taut mooring, Synthetic rope, Installation...
