3 Presentation Overview 3D Hydrographic Mapping for Real-Time Underwater Assessment What is Real-Time 3D Sonar? New Methodology for 3D Mapping! 3D Real-Time Mapping User Applications Real-Time Marine/Coastal Infrastructure Assessment Real-Time Subsea asset assessment and monitoring during construction Debris and Obstacle Avoidance Water Column observations Summary

4 Presentation Overview 3D Hydrographic Mapping for Real-Time Underwater Assessment What is Real-Time 3D Sonar?

5 What is Real-Time 3D Sonar? Multi-beam sonar has a narrow across-track swath that is prone to shadows in complex environments 3D Real-Time Sonar (Echoscope and Dimension ) have a volumetric pulse with typically 50 x 50 swath 3D Real-Time Sonar produces massive data redundancy and shadow reduction in complex environments

6 Two 3D Visualisation Modes 3D Camera Mode 3D Complex Mapping ONE sonar, TWO unique technologies, UNLIMITED applications

7 Presentation Overview 3D Hydrographic Mapping for Real-Time Underwater Assessment New Methodology for 3D Mapping! Dynamic Survey

8 Real-Time 3D Dynamic Survey Low ROI Excellent ROI Inspection High Density Mapping Monitoring Real-Time 3D is currently not suitable for large area hydrographic survey due to limited across track swath

9 Real-Time 3D Dynamic Survey 3D Real-Time technology IS revolutionary and a change agent by significantly improving the typical underwater construction process model of: Survey not involved Survey Process Data Planning Execute Task Survey Process Data Review Survey provides the pre and post data to the process, but is typically not involved during the execution phase of construction or inspection tasks.

10 Real-Time 3D Dynamic Survey to a more efficient, activity and results driven Dynamic Survey process of: Survey now 100% involved Survey Planning Execute Task Monitor Saving TIME and MONEY, and improving SAFETY and QUALITY

11 Real-Time 3D Dynamic Survey What does this mean in practice and what are the key benefits? We can continuously update the base survey map with real-time pre & post discrete survey data We no longer have to Mow the lawn instead we can Stop, Start and Loiter with full real-time 3D With unprecedented data density we can take non-conventional survey paths for shadow infill and full complex structure assessment We can see moving objects in 3D real-time - even superimposed over our near-real-time map and combined with static and moving 3D CGI models

12 Real-Time 3D Dynamic Survey: Case Study SLEEPER PLACEMENT BACKGROUND Zakum Development Company (ZADCO) Award National Petroleum Construction Company the Upper Zakum 750 Oilfield Expansion project 32 Pipelines, 400 Crossing Points and 2,500 Concrete Sleeper to be placed on the seabed from twin barges GOALS and OBJECTIVES Maximize Productivity Enhance Safety Deliver project to highest standard Pre and Post Survey Data As Built/Design Comparison

13 Real-Time 3D Dynamic Survey: Case Study EXISTING METHODOLOGY GAPS Beacons and TOGs Gyro on Sleepers to gain position and orientation results Multiple divers (6) used per sleeper during placement operations Deployment Rate typically 1 (one) sleeper every 2 hours (Maximum 6 sleepers per day) Pipelay Vessel PLB648 Shift limited to 12 operational hours due to diver requirement Separate multibeam survey required for presurvey and post-survey deliverable

14 Real-Time 3D Dynamic Survey: Case Study New Methodology Echoscope 3D Real Time Sonar to dynamically monitor deployment. 3D models inserted into the scene for guiding and placement. Accuracy & Efficiency Nominated ranges & tolerances met Improved Safety Divers now used for Quality Control Productivity Increase Up to 76 Sleepers placed in 1 day compared to 6 sleepers

15 Real-Time 3D Dynamic Survey: Case Study New Methodology Echoscope PRE and POST survey data is collected by the Echoscope mounted on the barge during transit TO and FROM each sleeper location.

16 Real-Time 3D Dynamic Survey: Case Study Move to new Location Collect Post- Sleeper survey Collect Pre- Sleeper Survey Monitor sleeper placement Inspect Target area and adjust design

18 Applications:Real-Time Marine/Coastal Infrastructure Assessment 2 minute critical infrastructure assessment.. Real-time 3D Image Divers on-board Client on-board Real-Time Recovery plan 3D assisted dive

19 Applications:Real-Time Subsea asset assessment and monitoring Echoscope Instant Results NO Post-Processing

20 Applications:Subsea asset assessment & construction monitoring Real-time 3D Image Position Dredge Tool Monitor Progress Dredge to Surface Monitor collapses Volumetric calculation and bathymetry

21 Applications:Subsea asset assessment & construction monitoring

22 Applications:Subsea asset assessment & construction monitoring We have successfully applied the technique of overlay models for guidance in cable lay projects and touch down monitoring.

23 Applications:Subsea asset assessment & construction monitoring MATTRESS INSTALLATION PROCESS CHANGE The process workflow below shows the pre-echoscope methodology and below, the Echoscope derived process with all active tasking's in parallel for significant real-time improvement

24 Applications:Debris and Obstacle Avoidance

25 Presentation Overview 3D Hydrographic Mapping for Real-Time Underwater Assessment Summary

26 Summary of Using Real-Time 3D Presentation Overview Survey have the opportunity to play a complete workflow role in a wide variety of construction and complex monitoring projects Wider team involvement with users understanding more from the high resolution images, and the engineers still can get what they need Engineering Image is the key not just the bathymetric data Instant verification, speed of assessment, prevent rework and full 3D deliverables
