Why should we inspect our underwater structures?

“Out of sight, out of mind”

It is easy to forget something that is out of sight, even though it is a very essential part of your everyday work. That certainly goes for underwater assets. They often face the heaviest wear due to the environmental stress and traffic but at the same time the signs keep hidden under murky waters. Checking the condition of underwater assets also seems laborious and pricy as it is formerly done by divers.

4 Everyday Challenges for Port Managers

1 The information about port’s assets and operations is diffused

Ports handle different kinds of data ranging from maps and drawings to information regarding traffic and transport. Some of the data can be archived in hardcopy form, for example drawings of old structures or maps of rental areas. Additionally, there is information about structure inspections, repair plans or diver reports recorded on hard drives or even emails. More over, add different software and databases to the mix as well. So, when you want to locate certain information, it may require a good amount of work, browsing through files or calling different people for it.

2 Data sharing with different stakeholders requires a lot of work

You have just received survey data of a quay area and you would like to send it into designing for expansion planning. The difficulty is that you don’t have the right software to open the data in 3D, for example to verify the right areas to be sent. The maintenance crew just also sent you some pictures taken with ROV to highlight damages from last week’s collision, but you don’t have the exact location. So now you send Dropbox links and pictures via email, and try to contact the surveyor to find out which survey data file is which, and also call maintenance guys to show the exact damage regions to the divers.

3 3D data is difficult to use without the right software and education

The point cloud data picture is usually quite hazy and files do not open without a supported software. They might also be heavy files making it difficult to work with on a basic computer. If you are not used to analyzing point clouds it may be hard to see any significant findings. 3D data may also be stored on some USB-drive and forgotten about. The point cloud can be used in a construction project by a designer, but if not maintained regularly, it will eventually be outdated.

4 The data is outdated

Maritime transport is a fast-paced business where efficiency and safety play important roles. You need to have information about traffic, weather, and conditions of the infrastructure to operate efficiently, while the information has to be up-to-date and accurate. If there is no possibility to easily update possible repairs or other changes onto some common database, the new information might not reach everyday users.

How can you solve all these challenges and manage assets easily online?

GISGRO is an online platform for all kinds of 3D data and includes sophisticated tools for smart asset management. The digital twin of the assets act as starting point and can be enriched with observations, remarks, drawings, pictures, etc, basically adding any kind of information needed. When all the information is in one platform, it is faster to find for example quay’s carrying capacity, check the rental areas or find the location of a broken pile that needs fixing. Better yet, you can even make a work order for that fix straight via GISGRO.

The planning of maintenance is easy; when you have the 3D data of the port you can measure and calculate dredging areas, compare different datasets to see if the damage has expanded and send the exact location of the broken bollard or identify the owner of certain rental area. The user interface is visual and easy to grasp, that is also compatible on mobile devices. No need for days’ worth of “getting started” courses.

When  3D data of your assets is a natural part of maintenance and management, it stays fresh and can be used as a strong base in planning maintenance, repairs and expansions. If you want to know more about this opportunity to ease your life, contact us!

Types of observations in underwater structural inspections

Long experience in underwater structural inspections

VRT Finland Ltd has performed complex underwater structural inspections since 2010. We were the first to use sonar scanner for vertical structures; previously the sonar scanners were only been used for hydrographic surveys. As the technology developed, we moved from static sonar to mobile multibeam sonar surveys, which made the service suitable for a quick inspection of wide areas.

What are the main ingredients for top quality survey data?

Advanced measurement equipment is nowadays easily available and affordable to companies performing underwater inspections or airborne measurements. Data acquisition from under and above water is becoming more common and 3D data more voluminous as companies, cities, and third sector organizations are eager to have their assets digitalized. This also means increase in the amount of data acquisition related service providers in the field, which may lead to increased variability in quality of the data. In this article we discuss the ingredients of top quality survey data. Continue reading…
