Ropes made with Dyneema are proving a success in drill rig mooring systems which are typically relocated every 3-6 months during the span of a campaign, incurring time and heavy cost. With Dyneema based systems every rig relocation delivers OPEX savings through a multitude of operational and performance beneÞ ts. In the course of re- locating a drill rig the lighter ropes can translate into up to 40% faster mooring and installation compared to polyester. Rig down time is reduced considerably as hookup speed is expedited. It also means smaller Anchor Handling Vessels can be used, and less trips to shore are required. Belgian Dredging International switched its barge moor- ing lines from steel wire ropes to ropes made with Dyneema. While initially more expensive, the improved productivity, ease and speed of handling and safety all reportedly made these ropes well worth the investment. The saving can come from unexpected sources too. Ropes made with Dyneema need no oil or grease, elimi-nating the need for grease, as well as the cost of manpower needed to apply and clean it up. In many cases, the period needed to payback the initial investment for these advanced ropes is short, particularly if you factor in the absence of injury-related costs, as well as those costs for maintenance, repair and replacement. ÒDuring the use of the ropes only minor abrasion could be observed. This contributes to their long life,Ó said Jorne Beyen of Dredging International.
