Dekra Industrial: ‘on the rise’ in the oil and gas sector
26 January 2023
Dekra Industrial SA has been involved in non-destructive testing (NDT) and inspection in the oil
and gas sector – locally and pan-Africa – for some 5 years now, and the company continues to
grow its presence in this critical area of the energy arena. This takes place against a
background in which – according to global management consulting firm McKinsey in its Global
Energy Perspective 2022, released in April last year – the peak in fossil-fuels demand
continues to move forward, with oil projected to peak in the next 5 years, while gas remains the
most resilient fossil fuel
This trend is evident from the high level of activity off the coast Africa, for example
TotalEnergies’ pivotal liquid natural gas project offshore in Northern Mozambique.
Dekra Industrial Managing Director Johan Gerber explains: “Offshore oil and gas rigs present
potentially hazardous working conditions while the crew members carry out the required drilling.
Rig teams are dealing with highly combustible materials, on an ocean-based platform where
cranes are swinging heavy equipment overhead, and other large-scale moving parts are also a
constant presence in the immediate environment.”
Johann Dorfling, Dekra Industrial’s Western Cape Branch Manager, notes: “We are active in the
oil and gas and maritime sector both on -and offshore; and have carried out ‘before and after’
NDT welding integrity inspections around Africa, such as Las Palmas in the Canary Islands,
Ghana, Angola and in Mozambique.
On oil rigs, we do crane and slew bolt inspections – and work extensively on drilling risers,
which form the connection between the subsea field developments, and production and drilling
facilities. An extremely high level of welding is required to ensure that the longevity and
structural integrity of the components, structure and pipework on the risers is maintained, as
many of these items undergo extreme pressure during their service. NDT and inspection help to
prevent the failure of these critically important elements.”
The role of NDT and inspection on drilling risers
MC Liebenberg, NDT Level 3 Technician at Dekra Industrial, clarifies: “Similar to pipelines or
flowlines, risers act as conduits to transport produced hydrocarbons, as well as production
materials, such as injection fluids, control fluids and gas lift. The cost of a marine drilling riser
system can be tens of millions of dollars, but the cost of operational downtime associated with a
riser loss or failure can exceed more than one hundred million and this therefore needs to be
prevented.
In non-destructive testing, there is not one method which is superior to another, and the
methods complement each other. In offshore inspection, we most commonly see the use of
magnetic particle (MT) and visual inspection (VT), as well as thickness gauging.”
Dorfling adds: “We have performed eddy current, MT and VT inspections, liquid penetrant
testing (PT), volumetric as well as ultrasonic UT and phased array ultrasonic testing (PAUT)
welding inspections on drilling risers. It is of vital importance to ensure that these risers are in
class and do not fail in service, as the result of a leak can be catastrophic for the environment
and general safety.”
In – or out – of class
Liebenberg clarifies: “Depending on the acceptance criteria of the inspection, NDT can
determine if all areas of inspection are in or out of class, and reported on, detailing the extent of
wear, corrosion, or defects discovered.
“Dekra Industrial does not determine if a vessel is out of class or not – this is determined by the
results of our NDT inspection, which are presented to the client, who then makes the decision
on whether to replace the component, or repair it to conform to class standards.”
Rope inspections – a competitive differentiator
Dorfling explains that DEKRA Industrial offers rope access inspection across multiple NDT
methodologies, including advanced disciplines such as PAUT. “Dekra’s capabilities in
performing NDT offshore with rope access competitively differentiates us from a number of our
competitors, and this is of great importance in this industry – as is the ability to provide a
diverse offering,” he enthuses. “We are proud to be able to perform advanced inspection using
rope access, as building scaffolding on a rig is not a viable option.”
Managing Director John Gerber concludes: “Dekra Industrial in South Africa has played a major
role in the fields of NDT and inspection locally – across a wide range of industry sectors – for the
past 40 years and we are proud to include this important area – NDT and inspections in the oil
and gas arena – in our field of expertise. We anticipate doing even more maritime-related work
in the future.”
