Cathodic Protection Underwater Automatic Inspection Technology

(CP-UAIT)

BaltRobotics- 2014

“The lack of breakthroughs in wireless

underwater communication and battery capacity

is prolonging the wait for a fully autonomous

underwater vehicle (AUV), one that will not need

a $ 100,000/day vessel and crew, a heavy tether

for power and control or hours to complete a

task that might take minutes onshore”

The Challenge

- Pressure capability and hence theoperational capacity of O&G pipelinesdeteriorates rapidly over their lifecycle.

- Increasing environmental awarenessfollowing BP Deep water Horizon spillnecessitates a more diligent approach tomaintenance

The Challenge

New regulatory and audit requirements:

- Safety and Environmental Management Systems(SEMS) by Bureau of Ocean Energy Management,Regulation & Enforcement (“30 CFR Part 250”)

- American Petroleum Institute’s (API) RecommendedPractice 75 (RP 75)

The Challenge

The 13 elements of RP 75 that the Workplace

Safety Rule makes mandatory are as follows:

-…. Audits: rule strengthens RP 75 provisions byrequiring an audit every 4 years, to an initial 2–yearreevaluation

The Challenge

Inspection methods:

- Visual inspection- Cathodic potential reading- UT (ultrasonic compression wave) - contact method- Flooded member detection (FMD) – unsafe method- EDDY Current- Sonar Leak Detection- Magnetic- etc.

All non-contact methods need underwater carrier

The Challenge

• Remotely Operated Vehicle (ROV) is very slow

and costly

• High CAPEX and OPEX for ROV and mother

ship

• Associated CAPEX risk due to loss of or damage

to ROV

ROV Approach

ROV Approach

ROV Approach – Petronas

(Malaysia) example

• Visual control

• Inspection video recording

• Cathodic potential recording, CP-gram

formation

ROV Approach – Petronas

(Malaysia) example

• Cost of work – 75,000 -100,000 UDS/day

• Productivity – 6-8 km/day (depends on

weather conditions)

ROV Approach

Advantages:

• existing and proven technology

• the number of installed ROV: survey

equipment, and vessels

• the pool of trained staff

Disadvantages:

• high CAPEX & OPEX

• high risks (ROV loss)

• limited area of operations (shallow water

limitation)

The Solution

To create low CAPEX/OPEX system for CP

inspection and visual inspections using

Autonomous Underwater Vehicle (AUV) as

carrier.

AUV Approach

AUV Approach

AUV Approach

• System allows pipeline operator to inspect

greater pipeline lengths more frequently.

• System allows multiple AUV operations from

single mother-ship

AUV Approach

Advantages:• low CAPEX & OPEX• low risks• unlimited area of operations (deep and shallow water)• proven worldwide tendency of the development• carrier for any inspection equipment

Disadvantages:• lack of underwater communications• lack of battery capacity• new technology • needs the investments• has to be implemented

“yellow” – it had been resolved by BaltRobotics

Our project

“BaltRoboticsSp.z.o.o.” (BR) –

http://www.baltrobotics.com - has developed and

tested a proprietary system that has applications in

particularly for low cost underwater Cathodic

Protection (CP) inspection of Oil and Gas pipelines

using AUV as a carrier.

Our project

1 – Vessel; 2 – GPS; 3 – AUV; 4 – Remote Underwater Docking System; 5 –

Navigation Current Generator; 6 – Ultra-Sonic Distance Measurement and Data

Transmission System; 7 – Ultra-Sonic Data Modem; 8 – Current Navigation Unit; 9

– Video Cameras; 10 – 3-D Video Compression System; 11 – Wire Connection and

Transportation Unit; 12 – Contact-Measurement Wire; 13 – Engines; 14 – CP

Measurement Unit (Calomel Electrode); 15 – Embedded Computer; 16 - Beacon

Unit; 17 – Power Supply Unit;

Main advantages of our System:

• The System can be used with a Vessel muchsmaller than ones that follow ROV (RemotelyOperated Vehicle).

• The System delivers the possibility to inspectseveral sections of the pipeline with ONE Vesseloperating several AUVs. It decreases the totalcosts of the inspection.

• The System can be used with the higher waves(rough weather: rain, wind, etc.) in comparisonto ROV-based technology.

Main advantages of our System:

• The System delivers more effectiveness of theinspections in comparison to ROV-basedtechnology – one operator can inspect moredistance of the pipelines.

• The CP Protection Inspection Report will include3-D Video Images that are matched with themeasurements of CP Potentials measured.

• AUV could carry any underwater inspectionequipment
