This paper will demonstrate the benefits realized from a towing and positioning system made of syntheticropes, rather than traditional steel wire rope, to deliver the MarsB-Olympus TLP for the critical inlandtow, open water tow and positioning spread during the TLP Installation campaign. This is the first timeShell has used synthetic ropes for an installation of this magnitude.Documented throughout the paper is the methodology used to evaluate the operational efficiencies ofsynthetic lines, Concept Proof Testing, the unique challenges of the inland tow, and the risk managementplan required to make the offshore tow and positioning during hurricane season. Additionally, earlyengineering and design determined that using synthetic ropes would allow standardization of the towinglugs and the ability to replace unique and complex one-off components required for steel wire rope witha much simpler, proven design. In all three phases of the installation, the lines were rigged quickly andefficiently by a minimum of crew and without additional handling equipment. Most importantly, none ofthe synthetic ropes failed during the transportation and positioning phases.
