Online's range of acoustic receiver systems, when used in conjunction with an acoustic pinger, provide a reliable means of tracking and locating a stuck pig in a subsea, liquid filled pipeline, resulting in substantial cost savings.

The range of receivers also allow for detection of a signal from subsea warning beacons or alarm pingers.

The diverse range includes ROV and diver held solutions to suit various applications.

The receivers can be tuned to a wide range of frequencies, making them compatible with most other manufacturer's equipment.

Modular ROV Receiver

  • Online's modular ROV receiver system provides an accurate method of locating and tracking a pig fitted with an acoustic pinger.
  • Directional hydophone provides increased precision
  • The received signal can be relayed back to the surface via RS232 allowing it to be interpreted topside.
  • Parameters such as sensitivity and frequency can be manipulated topside, giving the operator full control without returning equipment to the surface
  • The system comprises - 2001RS Topside Receiver, 2401 Subsea ROV directional Hydrophone & 2402RS Subsea Interface
  • The 2401 can be mounted on the skid or held in the manipulator of the ROV with the 2402RS mounted on the skid.
