Virtual VideoRay Insights Presentation Series

July 21, 2022

Tunnel Vision during Underwater ROV Inspections 

10am – 10:30am EDT

Kevin Tomanka, EIVA

Tunnel inspections are one of the more challenging types of underwater survey, and for several reasons: the length and shape of the tunnel, murky water, and zero visibility.  Each factor presents a unique challenge to the ROV, which often puts demands and restrictions on the hardware and software. In response to this, ROV operators are turning to customizable setups with NaviSuite Mobula Pro + Processing (VideoRay), a versatile software to overcome these difficult conditions. 

It’s All about the Data – Recording, Integration and Deliverables 

10:30am – 11:00am EDT

Tom Glebas, VideoRay

Many ROV projects depend on data from other sources, for example, a list of target coordinates, or the goal is to collect data and create reports.  This presentation will discuss the data collection related features and capabilities of Mission Specialist systems and present some auxiliary tools that make repetitive data collection and reporting tasks easier. 

Future Insights Presentation Events

NDT (Non-Destructive Testing) Methods Primer 

Non-destructive testing has been around for decades and has been used by divers and ROVs for underwater inspections.  This primer will provide information about the features and capabilities of various systems including Ultrasonic Thickness Gauges, CP Probes and multi-sensor Sondes.  Does your next project involve NDT? 

Presenter:  TBD 

SAT2Chart – A Map Is Worth 1000 Coordinates

Driving an unfamiliar route to a destination? Then you’ll probably use a map application that has an overhead view of your location, destination and route. So why not have the same ability with your ROV?  


Enter SAT2chart. 

SAT2Chart is a free program that converts map data to .KAP files. Once converted, these files can be imported into Greensea by simply dragging the file into the map display and… Voilà! An overhead image of the selected area will appear. However, these files don’t generate themselves. There are a few steps to follow when creating charts and, if you’ve been out of the “Insights” loop, our one and only Arely Hernandez gave a presentation specifically on creating charts and can be seen [here]. Full instructions on installing and creating charts can be viewed [here].

Greensea Playback + OBS

Let’s imagine a scenario where you just finished a mission AND you remembered to press the record button *applause*.  The customer and your supervisor now need to see all the data you collected from your mission. Thankfully, Greensea has the Playback feature which replays your mission in the Greensea interface exactly as it was when you originally performed the mission. However, there may be problems with delivering the playback. For instance, the customer and your supervisor may be thousands of miles away and they don’t have access to Playback. At this point, you’d probably throw in the towel especially if you weren’t subscribed to VideoRay’s Insights newsletter but thankfully that isn’t the case.  

The best solution is to use OBS to screen capture the Greensea playback.  Our installation and instructions for using OBS can be found in our “Wet Paint” section of our Library. Once recorded, save the .mp4 on a flash drive and upload it to your personal computer so you can send the video in a email or share in the cloud. Below is a link on how to install and use OBS.

FAQ of the Month – Be “in the know”

Q:  Why does my ROV’s DVL (Doppler Velocity Log) lose its lock? 

A:  First, the DVL has a minimum (0.2m / 8in) and maximum range (75m / 250ft).  While you might get a lock outside of this range in some conditions, generally these are the limits.  The DVL also requires a clear line of site for at least 3 of the 4 beams.  If beams are blocked by a cable on the ROV or you are close to a pier wall, the DVL may not maintain a lock.  Another common source of problems is bubbles on the transducers or in the water below the DVL.  Bubbles can form from the propellers creating cavitation on the surface or natural causes.  If cavitation is the source, you can change the ROV’s depth and quickly yaw the vehicle, to shake any bubbles free.  Bottom conditions can also lead to unstable DVL performance, particularly when the bottom has plant growth which can interfere with a good acoustic return.  Of course, a problem with the system can also cause DVL problems. 

If you suspect a hardware or software problem, contact support@videoray.com for assistance.

Laser Scaling Tool

The Laser Scaling Tool projects two parallel laser beams a fixed distance apart.  The projection of these points onto objects in your video can be used to scale the size of object.
