COMBINED APPROACH
1. FDI – Fast Digital Imaging technology
2. Combination remotely controlled unmanned surface vessels and integrated underwater vehicles (tethered or untethered)
MASS – Marine Autonomous Surface ShipsMAS – Marine Automated Systems
Autonomy vs Remote Control
![Page 5: Realising efficiencies in pipeline and asset inspection · DeepOcean, FAST ROV 2. 2018 North Sea (301km 114.49hrs 2.63kmh) i-Tech7 –Reconfigured WROV 3. 2018 T&T (432km 193.72hrs](https://reader034.vdocument.in/reader034/viewer/2022050519/5fa2b01f283cb2026a6e35ba/html5/thumbnails/5.jpg)

WHY?
5
1. Address the Target Zero carbon reduction agenda2. Reduce Risk to Personnel – Key operators working
from shore3. Perform inspections Faster Fast Digital Imaging (FDI)
Inspections / FROV4. Perform inspections at Lower Cost Marine
Autonomous Surface Ships (MASS)5. Higher quality digital data moving toward
automated processing6. DATA is KING Gather ONLY what you need
Automated editing, event and anomaly detection
FDII + USV + UV = Success!

FAST DIGITAL IMAGING – WHAT IS IT?
• FDI Inspection is a TECHNIQUE, not an Inspection category• FDI replaced Video with Stills Imagery and contact CP with
Field Gradient CP.• Data is acquired in a single pass, processed and reviewed
‘after the acquisition cycle’• FDI is ideally suited for Fast ROV, AUV or Remote Operations
Combi systems• FDI may be configured for GVI or FGVI by adjusting sensor
configuration and geometry

FDI INSPECTION - LESSONS LEARNED
4 FDI Inspections completed
4 campaigns, 3 contractors, 4 configurations
BUT … improvement areas such as:• Lack of consistency in data products • Unexpected additional costs for processing• Delays in data delivery• Poor QC of deliverable• Misalignment with expectations of integrity engineers

Acquired data:
Navigation and Mono, stereo or triplicate imagery and integrated laser (NOT time of flight)
Processing:
• Catalogue of high quality colourised imagery
• 2D ortho rectified mosaic
− Co registered laser / imagery delivering high density 3D colourised points cloud
OR (proprietary software)
− 3D ‘mono’ points cloud direct from laser (product of geometry – not T.O.F.)
• Plane photogrammetric processing (3D Scene files – vSLAM / stereo, triple perspective)
− MESH either created from laser OR photogrammetric points cloud
− Creation of MESH (varying densities) over which ‘surface’ is placed
• Use of feature mapping to calculate internal and external camera alignments
• Use of feature fapping to identify common features between images to construct sparse points cloud
− 2nd stage = creation of dense points cloud

CHALLENGES (JUST A FEW)
18
• Over the Horizon Operations• Base facility & manning requirements• Vessel endurance, depth and weather capabilities• Maintenance & Reliability (vessel & vehicle)• Launch & Recovery / tether management• Underwater vehicle communications & control• Bandwidth and latency (USV / Combi situational awareness and
control)• Automation vs autonomy (or level of autonomy)• Emergency recovery / failsafe / contingency planning• Regulatory requirements (COLREGS/MASWRG/local reg.)• How will IMCA address USV regulations?

1. Lower carbon footprint and enhance HSE performance through application of these systems
2. BP is modernising and transformation our business to make inspection more efficient
3. FDI is a renaissance technology. FDI is data focussed with even greater efficiencies to be realised through the implementation of unmanned – tethered / untethered underwater systems operated from shore.
4. BP will review and implement advanced and alternative inspection technologies in all areas to further increase inspection efficiency.
