The

The Complete Packag
ready to Mobilize |
Small,
rapid and efficient mobilisation
and deployment, small footprint
(The entire system weighs less than 70 pounds
and packs neatly in two rolling
Pelican cases that can be carried in a car
trunk or helicopter, or checked as airline
baggage and transported by one
person) makes the SubNet Services VideoRay
ROV offshore inspection package and attachments
such as a Thickness Gauge extremely
cost effective, for those quick
one off jobs, or even feasible now as a
low cost permanent stand by service. |
Quick
Hire
SubNet
can hire the system with or without Operators
who may if required also be CSWIP Inspection
Qualified.

Oil
Rigs and Pipelines
When pipeline surveys are required,
the VideoRay is an excellent tool for inspecting
the path and ocean floor. Using a sonar along
with the VideoRay, the operator can carefully
check all underwater features. Because the flight
is recorded on Digital Video along with depth
and heading, engineers and scientists can carefully
review the footage at a later date. Small and
not invasive, the VideoRay can fly close to
the bottom without disturbing sediment. The
VideoRay is more portable than other work class
or inspection class ROVs and does not require
special mobilization.
Example:
A work class ROV
on a North Sea rig had broken down, and the
client wanted action quickly. Due to the location,
it was impossible to get a replacement ROV sent
out in time unless it could be transported by
helicopter. In principle, the job was simple:
a BOP was being raised from the seabed and its
passage to the surface had to be monitored by
the ROV.
In this application, the client attached the
VideoRay to a taught wire instead of flying
the submersible on its tether. Though the VideoRay
could handle the current, the transponder the
client wanted to attach was too large to add
to the submersible, which is 14 inches long
(350 mm), 9 inches wide (225 mm), and 8.5 inches
high. Using the taught wire also allowed the
crew to lower VideoRay with a great deal of
control while preventing the possibility of
snagging it on other lift lines.
A little creativity went a long way, and the
solution was cost effective. The rig time saved
by using the VideoRay was considerable. To mobilize
another work class ROV would have taken several
days and required the use of a dedicated vessel
to get it to the location. Major downtime was
prevented, the job was completed, and the oil
company was pleased.
ROV with Thickness
Guage
|
The
VideoRay's size makes it a marvel of engineering,
but don't let it fool you. It is a micro ROV
with serious capabilities, proven reliability,
and a robustness that gives confidence.
We rent out our VideoRay Offshore System with
or without Operators (Inspection Qualified if
needed) in various packages according to project
requirements. |
