ParticipantPdf for our latest laser reference pointer.

The laser references can be used for projecting stripes onto pipelines- really good for aligning boom cameras (align all the cameras onto the same point). Saves time when you clout a rock dump or the spoil heaps on the trench side. Also you get a good idea of the cross section of the pipeline.

ParticipantUsed something like that – works good – I agree 💡

ParticipantWho made them first – you or Tritech 😀
Theres a Tritech one on one of our boats for lining up all the cameras on the same spot.

ParticipantHey, if you want to trial ours, I’m happy putting ours on a head to head.
What color stripe do you want? I can do a Fugro orange if you like !
I believe the first laser system in commercial application underwater was somewhere in the region of 1988. At that time, I think I was a regular to watching anything from "jackanory" to "teenage mutant ninja turtles" and lasers were used to blow up spaceships. I don’t think we are the first by any account.

If it was Fugro colours it would have to be brown!

Participantah, color recognition…… my achiles heel….. 😯

Participantthink the tritech one was a type 3b (green) laser if i’m correct, is yours as powerfull?
August 6, 2007 at 1:31 pm #13011Savante
ParticipantYup most certainly. We have 3B versions and also a class 2 and 2M units for working with divers – measuring distances between structures and gouge lengths, etc.
Diver versions are available in green/red/blue. Depth rated to 400m (limit of sat divers I believe x safety factor)
ROV version is green/red/blue/violet. – Depth rated to 4500m. Red for short range, green/blue for ranges beyond 2m total distance.
All systems have proper anti reflection coatings on them so you don’t get funny little "satellites" or ghost images.

ParticipantAnyway, if you want a proper subsea laser metrology tool for doing pipeline surveys or spool piece metrology, then you want to have a look at this…

Participantsorry, it took me quite a while to think how best to respond to Ray and truered.
The question you should really ask is, who put the optics package together for that other laser product.
hmmm…. I’ll give you two guesses………..
November 5, 2007 at 10:10 am #13014Scott Beveridge
ParticipantI think there were a couple of other folks that used laser measurment / metrololgy in the game (there were a couple of major players in the O & G industry that actually didn’t buy the idea…) and they were research orientated. MBARI, Wood Hole, and I’ll get get back to you on a few more….
Brilliant idea isn’t it???

ParticipantUnfortunately Viz is the key factor followed by distance 😕
And due to the fact that no one has got round the problem of Fish Farts , using lasers underwater is a fifty fifty 😯November 5, 2007 at 12:10 pm #13016Scott Beveridge
ParticipantLost,
Turbidity is indeed a problem for not only lasers but VOS (transponders, sonar / profilers, etc.)
November 5, 2007 at 1:13 pm #13017Andy Shiers
ParticipantYou cease to amaze me in your vocabulary Scott 😀
November 5, 2007 at 2:51 pm #13018Savante
ParticipantAgreed, using a laser to perform the same sort of task as a collision avoidance sonar is difficult and compromised by turbidity due to fishy feacal farts. But this happens with sonars, profilers, altimeters too.
It could be done, but far better, cheaper, easier to meet the applications where sonars are found to be lacking. These areas are typically where high resolution and precision are required.
General rule – if you can see it, you can measure it using a laser without problems.
