GENERAL DESCRIPTION
The 600 Series Pingers are high specification, microprocessor controlled acoustic transmitters
developed for use as advanced PIG transmitters and for other subsea marking and location
functions.
A 600 Series Pinger may be fitted to a PIG for use in offshore, fluid filled pipelines. The
acoustic signal generated by the pinger is exceptionally powerful and stable and allows the
approximate PIG location to be established from the surface using an acoustic receiver and
hydrophone (e.g. OEL 2001). The exact location can then be determined using a directional
receiver such as the diver operated OEL PR1, or ROV mounted OEL 2001RS/2401 system.
The 600 Series Pingers are highly configurable and their performance and functionality can be
tailored to meet specific customer requirements. For example, if two pingers are required to
operate in close proximity to one another, different frequencies and/or ping rates can be
configured during manufacture to allow for differentiation between their transmissions.
The 600 Series Pingers are capable of sending acoustic transmissions up to 2km, although the
effective range is dependent upon the specific configuration, mounting arrangement, and
environmental conditions.
The standard 600 Series model (shown in the figure above) is powered by 3 Alkaline C Cells
and produces up to 10W of acoustic power at a single operating frequency in the range of 26-
42kHz (configured at time of manufacture). In addition to the standard model a number of
alternative configurations are available that offer additional functionality and/or performance:
EXTENDED HOUSING OPTION: Extended housings are available that increase the battery
capacity from 3 to 4 cells. These configurations have an increased length of 317mm and an
increased weight in air of 1.35kg.
SHORTENED HOUSING OPTION: Shortened housings are available that decrease the overall
length to 217mm and decrease the overall weight to 0.85kg. The short version accommodates
two C cells.
LITHIUM CELLS OPTION: Lithium C cells may be fitted in place of the standard alkaline C
cells and will significantly increase the battery life of the unit (short and standard housing
configurations only).
DUAL RATE OPTION: 600 Series Pingers with the Dual Rate option incorporate an external
connector cable that allows them to be interfaced with an external piece of equipment for use
as a long range, remote alarm. For example, a 600 Series Pinger with the dual rate option
may be interfaced with an OEL Smart Gauge Plate and used to send an alert if the gauge plate
is triggered.
GRID™ OPTION: Has the same functionality as the Dual Rate option above, except that the
unit also transmits the time of a BWGP event as a series of acoustic pulses. This allows the
location where the event occurred to be determined without having to recover the pinger first.
