SELECTED PROJECTS
Projects selected are meant to be used mainly in deep water operation on the
management of riser integrity:
1.
A.U.R.I. – Autonomous Underwater Riser Inspection Tool;
2.
Monflex – Monitoring of Flexible Oil Lines.
A.U.R.I. PROJECT
Objective:
1.
Managemente of riser integrity;
2.
Inspect the vertical section of the riser in order to detect Corrosion and
Fatigue with lower price and safer technique.
The A.U.R.I inspection may be set by 4 different parameters (also means
redundances in case of failure):
•
Maximum pressure on depth sensor ;
•
The length of the run;
•
Maximum mission duration;
•
Maximum allowed tilt (inclinometer) < 30º.
A.U.R.I. PROJECT
Most used technique – ROV for visual inspection:
•
Requires experienced operator;
•
High cost – special vessel;
•
Continuous monitoring.
Pipeline with anomalous diameter variation
Polymeric sheath damage and exposed
armour steel layer.
A.U.R.I. PROJECT
A.U.R.I Tool primary concerns:
•
Not getting trapped under the TDP (Touch Down Point) and not
getting crushed by the weight of the riser causing damage to the
pipeline;
•
Severe electrical failure, returns automatically – Positive
buoyancy;
•
Mechanical fuses break without releasing sharp pieces – in case of
rescue with ROV is needed.
A.U.R.I. PROJECT
A.U.R.I Tool
Suspension:
•
Eight rollers – diameters from 190 to
360 mm;
•
Absorb impacts and negotiate variation
preventing AURI from getting stuck.
Propulsion:
•
2 thrusters;
•
Used to do all the inspection (positive
buoyancy only for the safety of the tool.
A.U.R.I. PROJECT
Onboard sensors: four cameras, pressure transducer, odometers, digital
compass, inclinometer and thermometers;
•
Lights on only for a brief period – cameras shooting;
•
Digital compass – exact positioning of the acquired images;
•
Odometers – images each 300 mm.
Embedded computer and Software control the system after AURI starts, can
be upgraded and store the inspection data and logs.
The mission is considered complete when reach the parameters set:
pressure, distance, time and inclination.
A.U.R.I. PROJECT
Three options for launching:
•
From the surface of the platform;
•
Submerged with a diver;
•
Submerged with ROV.
Testing:
The AURI has only been tested in a pool environment with offshore tests.
A.U.R.I. PROJECT
Test Results:
•
Mission logic control worked for different returning criteria;
•
Returned without any human intervention;
•
The illuminating was considered appropriate;
•
Forces produced by the thrusters in agreement with the
manufacturer’s specification;
•
Dynamic friction on the rollers was higher than expected –
problem in suspension design;
•
Inspection of 1,000 m – estimated time is 44 minutes.
A.U.R.I. PROJECT
Prototype
A.U.R.I. PROJECT
Conclusion:
•
Challenges for an autonomous riser inspection tool;
•
Hasn’t been tested in real condition yet, but it seems to be good
alternative with low cost, low time, safer condition;
•
Possible to be used as a platform for new types of inspections
using other techniques, such as radiography.
AURI Video
MONFLEX PROJECT
Introduction:
As the operation water depth for flexible risers increases, the stress
level in these structures also increases. This higher load, associated
with stress concentration close to end fitting, can induce fatigue
damage in tensile armors at riser top section. Progressive rupture of
wires due to fatigue, which may be accelerated by corrosion, is an
important indication of deterioration in riser-end fitting connection, and
has become a typical failure mechanism for flexible riser top section.
MONFLEX PROJECT
Objective:
In order to mitigate the progression of these damages, this techniques
try to come with early detection of failure mechanisms at the riser-end
fitting connection, specially at the tensile armors with a continuous
monitoring.
There are techniques under development:
1. Visual torsion monitoring through video cameras;
2. Monitoring through optical fiber sensor extensometers.
MONFLEX PROJECT
Main damages:
• Usually caused during installation;
• Majority of occurrences from 30m depth to the platform connection,
more concentrated in the close end fitting;
• Torsional instability, external sheath damage and corrosion.
MONFLEX PROJECT
Visual torsion monitoring through video cameras;
•
Small angle deformation and on-line data acquisition in order to
provide immediate identification for non-conformities;
•
Procedure: attaching target on the riser – behavior on the videocamera;
•
Already been installed in 4 platforms and results were considered
efficient. Plan to install another 50 until the end of 2010;
•
PTZ (Pan, Tilt and Zoom) system on the cameras;
•
Multiple targets – 1 camera.
MONFLEX PROJECT
Visual torsion monitoring through video cameras
System:
•
Target picture and target
digitalized image –
comparison between the
images and a graph
showing the torsion
variation;
•
In case of excess of
variation on the
predefined values, sound
an alarm.
MONFLEX PROJECT
Monitoring through optical fiber sensor extensometers.
System:
• Many optical fiber sensors covering 100% of the wires;
• Remote sensing – software;
• Rupture brings tension from the operational tension to zero.

CONCLUSION
Searching for partners:
5.
