Offshore
Pig Monitoring:
Utilizing StarTrak’s “Pathfinder” Pigs
for
offshore operations, these can be monitored at
strategic stations along
the route of the pipeline either on a permanent
basis or during
operations or Inspections with MFL tools.
In water depths of 400-ft (140 meters) or
less the
sensors attached to or near the pipe, are
connected by cable to a
surface buoy, which contains an electronics
package, battery pack,
solar panels and satellite communication system.
In greater water depths communications from
sub-surface to surface may be achieved utilizing
acoustic technology.
This is a unit, which is known as StarTrak
“SoniSig”.
On activation the acoustic system
will emit a
train
of
data relating to time and location. Data is then
transmitted to a buoy
location, processed for onward transmission to
control centers by
satellite communication networks where
information is displayed on the
client’s monitors.
In the event that a pig becomes obstructed
its
position can be easily located utilizing a
StarTrak Marine Flux-gate
Gradiometer.
