During pipeline operations it is always necessary to know when a pig has left the launching trap and when it arrives at the receiver. Until located and released, a lost Pig means expense in vessel, equipment and personnel costs. Pingers give contractors a fast track to a stuck pig location. The ours product range of Pig Pingers consists of three models, to allow use in pipeline diameters from 150mm (6") upwards.All three precision engineered models are housed in stainless steel for maximum reliability and minimum maintenance. These heavy duty beacons are rated to an operating depth of 3000m. 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. Typical battery life can be easily extended by modifying acoustic output, pulse length or pulse repetition rate. Smart Pingers are designed to be easily installed in most Pig manufacturers equipment. When used in applications outwith pipelines, signal range of the Maxi-Micro smart pinger can be in excess of 10km.
