AnTech
sub-sea MDET detector system offers significant safety benefits
Posted: 12 March 2003
EXETER, England — AnTech Ltd, a specialist
engineering design and manufacturing company serving the international
upstream oil and gas industries, today announced the introduction
of the Sub-Sea MDET Detector system, a versatile wellhead sensor.
This wellhead sensor not only assists deep water operators to position
specialist equipment on the seabed, it detects the end of coiled
tubing inside of a riser.
Deep Water Benefits
With the industry moving further and further into deep water in
a strategic move to capture reserves that have previously proven
to be inaccessible, operators working in this environment face a
number of unique challenges. When working in extremely deep waters
of up to 10,000 ft, it can sometimes take upwards of three days
to deploy equipment on the seabed. “AnTech appreciates that
one of the critical phases of a successful deep water operation
is the safe and efficient positioning of equipment on the sea floor.
This is where the Sub-Sea MDET Detector can be of real assistance,”
said Toni Miszewski, Managing Director of AnTech Ltd. “This
system makes it possible to effectively ‘see’ through
steel tubulars by way of its remote audible and visible warning
system, making the process of proper equipment positioning a much
more precise and controlled activity.”
Bearing in mind that safety is always of the utmost concern to
underwater personnel, an added benefit of the system lies in the
fact that the sensors clamp on to the outside of the riser. As a
result, they don’t interfere with equipment or other necessary
activities being carried out on the seabed.
The AnTech Sub-Sea MDET is a wellhead sensor designed to assist
oil service providers involved in deepwater operations. The announcement
of this new system comes as welcome news, primarily because of the
improved safety benefits it offers to sub-sea operators. The warning
system allows equipment to be positioned within a sub-sea riser
with an accuracy of just a couple of inches.
Visual and Audible Warnings Alert Operator to Potential
Hazard
The AnTech Sub-Sea MDET works like this: a sensor is strapped
around the riser from the wellhead. It then detects the passing
of a magnetic marker, and relays this information to the cabin giving
both a visual and audible warning alarm to the operators.
“When we set out to design a wellhead sensor that would offer
a comprehensive warning system, we knew it not only had to relay
an alarm immediately, it had to be integrated into the wellhead
in an extremely non-invasive manner. With the Sub-Sea MDET Detector,
we provide the complete solution: a completely non-invasive system
comprised of a sensor that locates the magnetic marker and simultaneously
communicates a warning visually and audibly via a control panel
on the surface. This way, the operator can take immediate steps
to resolve the situation,” said Miszewski.
In addition to the obvious preventive measures that the Sub-Sea
MDET Detector offers to oil services providers working sub-sea,
the system is simple to operate and install.
The Sub-Sea MDET Detector was originally designed to detect the
end of coiled tubing through a riser, but as the equipment has evolved,
numerous uses have emerged. Such applications include the location
of equipment using a magnetic marker both sub-sea and on the surface,
and the positive confirmation of the passing of equipment downhole.
For example, detecting cement plugs. AnTech is confident that the
system is the most versatile non-invasive detection system on the
market today.
