Our Expertise and Involvement in the Metrology Sector

Oil&Gas

We have been working with high-accurate surveying since 1980. With millimeter and submillimeter accuracy on steel constructions like jackets, topsites, and subsea structures.Over the years, we have been involved in all types of methodologies where the accuracy requirements have been sub-millimeters.

In the Year 2000, we did our first underwater metrology using images as input for photogrammetry. The project involved measuring with +/- 0.2-millimeter accuracy within an area of 1 by 2 meters. The project was a success, and the rest is part of our story. Since the year 2000, we have been involved in more than 150 projects and 500 metrologies.

Moving objects

Since the Year 2016, we have been involved in the aqua sector developing sensors for the industry. This industry is different from the oil and gas industry since the object to be measured is moving. So, for this industry, we had to think differently from the oil and gas where the survey object is not moving. The solution is sensors with multiple cameras. This makes it possible to acquire the necessary information every time a set of images is acquired. This solution is highly usable for the Oil&Gas industry and many other fields where 3D models and imsges/video are required for inspection and documentation.

A few of the metrologies we have been involved in.

Vertical anchor support

Sunken vessel gaul - propellar

Sunken vessel Gaul - bow

Dan A - reinforcement

Dan A - Marking of jacket legs and nodes

Spool metrology - planning

Spool metrology - image acquisition

Metrology - marking of plem

Jacket survey - seafastning stub

Salmon in cage

Since year 2000 we have been involved in more than 500 metrologies/surveys using the single camera solution. Above are some examples.

Below is some of the projects in more details.

Jacket survey

Dan A

Modifying and updating Dan A jacket.

Removing 2 existing support levels and installing a new conductor guide.
Renew 6 anode clamps
Install 10 K-nodes

Steel-to-steel installation.
The accuracy achieved was better than requested.

World’s largest photogrammetry survey under water.

Every object was installed successfully.

Jacket pile and template survey

Baku

Installing jacket on top of piles driven 90 meters into the seabed.

Distances between piles are 70 and 90 metres. Total surveyed distance was 450 meters.
A template survey was requested and executed on the fly during the field work.

The accuracy requested was +/- 50mm.
The accuracy achieved was +/- 25mm.

World’s longest distance photogrammetry survey underwater.

Jacket was installed successfully.
