According to the team, a 12-inch
pipe can be inspected with a total
X-ray on-time of close to two minutes.
Currently, the Subsea X-ray is commercially available and performs reliably
at 2,000 feet. “Further product development is underway to enable subsea
X-ray at greater depth and under more
extreme and unconventional applications,” Venkatachalam says.
“This technology and this environment
require a completely different way of
thinking. While the underlying technology
is the same, a number of times we had
to go back and completely rethink our
approach to the technology, the housing,
the application,” Telesz explains. “This is
where partnering with Oceaneering really
paid off – with their understanding of the
subsea environment and how the product
would be used.”
The project was a collaboration between
GE Healthcare, which has a deep under-
standing of the radiography detector tech-
nology; GE Inspection Technologies, which
has expertise in design and application for
industry; and Oceaneering, an oil and gas
products and service company with expertise
in subsea environments and extensive expe-
rience in asset integrity.
The team knew that if they could enable
industrial radiography in a subsea environment, customers could improve equipment
reliability and reduce downtime. “In some
cases parts that were previously taken out
of service and brought to the surface for
inspection can now be inspected in place,
which is a major improvement,” Telesz says.
“We can help operators pinpoint an area of
concern on their equipment.
In the future the team hopes to be able
to help customers measure and quantify
defects and track conditions over time.
“We also hope to enable remote collaboration so operators can get an immediate
second opinion from experts onshore,”
According to the team, this equipment
pays for itself with the first day of production downtime avoided by a subsea installation, or the first time an operator reduces
the time of a maintenance outage by a day.
“We are planning future developments
that will help operators better analyze
the data gathered to make better pre-dictive decisions about their assets,"
Venkatachalam says. Ideally, GE will eventually have data for every pipeline in the
water, making the system safer and more
Remote cameras give operators a closer look at
the delicate manipulations necessary to conduct
subsea X-ray inspections.
