OEL's series of high specification micro-processor controlled pingers have been developed for use as advanced acoustic pig pingers and for other subsea marking and relocation functions.
Acoustic pig pingers are fitted to a pig for use in fluid filled offshore pipelines. The acoustic signal generated by the programmable micro-processor controlled pinger is exceptionally stable and its location can be established from the surface using a pinger receiver and Hydrophone. Where a pig is obstructed and halted, the exact location can be identified using a Diver operated pinger receiver or a ROV directional antenna. The antenna is connected via the ROV's umbilical to a surface pinger receiver.
Operating frequencies can be varied where it is necessary to mark more than one pig in a train and where differentiation is required. OEL smart pingers are designed to be easily installed in most pig manufacturers' equipment. When used in applications out-with pipelines, signal range of the Maxi-Micro smart pinger can be in excess of 8km.
