Product Overview
The Deepwater Polatrak SunStation
provides an improved, low-cost, convenient, cathodic protection monitoring
solution for any subsea application where ROV assisted CP surveys are
conducted. No more fooling with ROV mounted probes, or having to get a
qualified inspector offshore. The SunStation digital readout is powered by
solar cells, which are powered by the lights of the ROV.
Each SunStation is a single-channel device
with an independent ground, thus any Polatrak instrument can output to this
device. Anode currents, for example, can now be read directly, in real
numbers, as can current densities. This system can save an operator hundreds
of thousands of dollars in reduced inspection time, and improves quality and
repeatability of data to a level never before available.
The readouts are strategically located where
ROV intervention is required; CP inspection is achieved whenever the ROV
visits. The mounting panel around the unit indicates inspection point
location information and the designation of each channel.
Applications
- Subsea trees & manifolds
- Deepwater flow lines
- Floating production systems
- Pipeline sleds
- Inside soft ballast tanks and center
wells
- Anywhere ROV CP inspection is required
Main Benefits
- Competitive pricing provides rapid ROI.
- Eliminates the need for OQ personnel
offshore.
- Provides repeatable accurate data and
eliminates operator error.
Provides positive real-time verification of electrical continuity or
isolation.
- Eliminates the hassle of ROV interfaced
probes.
- Provides more selective measurement at
points not easily accessible with an ROV mounted probe.
- Reduces cost and eliminates wear and
tear on ROV systems.
