Seabed mapping using underwater laser profiler

[Savante]

Just posting a link to an article we’ve published on our web-site about the use of our underwater laser profiler which we’ve been using aboard a low-cost subsea towed sled vehicle for seafloor mapping. We’ve been working in conjunction with environmental researchers in the UK to qualify the dimensions of Sabellaria worm reefs and naturally-found cobbles on the sea floor in waters around the European Union.

It’s a bit of a departure from our usual work in oil and gas, but it’s been interesting for us and appears it’s quite an area of active interest globally. Believe it or not, but identifying clusters of cobbles is scientifically important as the gaps between them can support marine habitats at a small scale. Our underwater laser profiler has been enabling researchers to quickly quantify whether or not the dimensions of a cluster of cobbles meets a standard for being environmentally relevant.

The link to the article is below.

Savant would such equipment give good definition in a confined space ,, see my recent post as im tasked with finding some imaging sonars that will work in a very confined area

Hi John, yes; we’ve been working in many confined spaces; cells of a condeep-type platform gravity base structure for one. The major advantage over sonar is that we don’t have so many issues with multi-bounce and ringing echos with an underwater laser.

just a little bump, but we’ve created a number of other news articles on this; for those interested…

the profilers (part of a wider group of equipment) are available on our products page at;

It was an older version of the SLV-50 that we used for this. We found we were smashing into boulders a ****lot****.
