INSPECTION RENAISSANCE

Clearly messaging BP expectations:

3

5 INSPECTION CATEGORIES

FGVI - External assessment for gross risk GVI - Circumferential Visibility and CP

• Pipelines• Jackets• Risers• Hulls• Hardware

• Horizontal• Vertical• 500m zones

• All water depths

4

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

5

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!

6

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

Sensor geometry is key for maximise circumferential visibility

FDI INSPECTION TRACK RECORD

FDI inspections performed on Four occasions for BP:1. 2017 North Sea (478km 94.72hrs 5.05kmh)

DeepOcean, FAST ROV

2. 2018 North Sea (301km 114.49hrs 2.63kmh) i-Tech7 – Reconfigured WROV

3. 2018 T&T (432km 193.72hrs 2.23kmh) REACH MMT – Reconfigured WROV

4. 2019 North Sea (290km 82.4hrs 3.52kmh) i-Tech7 – Reconfigured WROV

In execution:

Caspian 798 kms (Acoustic / XOCEAN)

Planned:

Caspian – 140 kms in 2020 (FDI)

North Sea 300kms (FDI)

Key objectives:• Standardisation• Normalisation

Set the new industry ‘Norm’ for inspection

Vehicles

SensorsData

Vessels

Evolving solutions between surface vessels, underwater vehicles, sensors, data, comms and methodology

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

11

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

DATA PROCESSING AND DELIVERABLES

12

Delivering the needs of the asset integrity engineers to assess ‘condition’ of asset

➢ True high definition 3D representation with multiple points in common Z domain

➢ True colour

➢ True 3D spatial correctness

Automated processing

Automated event and anomaly detection

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?

19

BUT IT’S A BUSY SPACE ALREADY… JUST WAIT

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.
