Measurement Technology NW (MTNW) has recently completed a contract to provide installation, calibration and commissioning on an eight-point mooring monitoring system for Frontier’s drill ship, Duchess, off the coast of Nigeria. The new running line tensiometer and LCI-90 mooring monitoring system provides visibility into line tensions which will support mooring and rig movement monitoring. The Duchess is a 475 ft by 75 ft vessel which needs to stay centered over an offshore oil-well for months on end despite sea states and drilling activity. The MTNW Line Control Instrument (LCI) Mooring Solution allows the rig manager to keep rig positioning to within a very small tolerance for lateral movement. The goal for most rig managers is to maintain movement to within a 12 inch circle while drilling activity occurs. This is a .2% margin for error. “Without knowing exactly where your anchors are and the tension in your mooring lines, the rig manager can’t accurately position the ship,” said Tom Rezanka, Director of the LCI division of MTNW. “With subsea pipelines crisscrossing the bottom of the ocean and dynamic sea states, mooring line monitoring becomes a necessary part of rig management for personnel and property safety.” In a traditional mooring setup, if problems occur, the vessel operator will notice a sudden change in position and will attempt to rectify the situation before the ship drifts too far breaking the drill column

Lankhorst Ropes Offshore Division is undertaking a research project into the development of cut resistant jackets for mooring ropes in the Norwegian and Barents Seas. The project will be used to assess materials needed to reduce the effects of fishing trawler lines on synthetic fiber mooring lines. Deepwater moorings, beyond 800m, in the Norwegian and Barents Seas are subject to extreme weather and wave conditions. The synthetic mooring ropes must provide high abrasion resistance and be
