Alan Duncan, Managing Director of InterMoor UK, an Acteon company, presented findings from a recent Inter-M® Pulse field trial in the North Sea during a media event at the Offshore Technology Conference 2012 in Houston, Texas.
Developed by InterMoor, in conjunction with sister company, Pulse Structural Monitoring, the Inter-M Pulse is a long term mooring connector that has the capability to monitor and track the in situ tension of each mooring line and transmit tension data acoustically to the topside control room.
With the introduction of various sensors, the Inter-M Pulse can also detail inclination of the mooring line. Additional features include; full history of the mooring line, acoustic data transmission, on-demand data upload and a traffic light alarm system.
To ensure the technology of the Inter-M Pulse, a 76 millimeter (mm) (800T Minimum Break Load (MBL) unit was installed over the stern roller of an AHV for the Ocean Nomad Semisubmersible at Everest 22/10a in the North Sea in winter 2012 for a six month drilling campaign. The unit deployed was designed for use on all offshore units. The field trial mooring system consisted of a combination chain and fibre makeup with the unit installation located at the fibre and shackle connection.
