Hi guys!

The company I'm working for wants to buy an ROV and we were asked to scan the internet. We would like to buy a device that can be deployed without the need for a crane, as we are working mainly in the coastal area from small ships.

Until now we have a good opinion on the Saab SeaEye Falcon. We would like to mount a Blueview device for microbathymetry and also to carry as much weight as possible, have a good versatile arm and a high resolution camera.

It would be very helpful if you could tell me facts regarding your personal working experience with those type of ROVs, after all the websites are made to show only their strengths and professionals that operate them can give the best piece of advice.


Thanks a lot,
Vlad

My experience offshore (at various levels in the food chain) indicates that most SAAB seaeye brushless DC thruster based ROV units are very reliable. It's a case of deciding what best suits your operational budget. Call them up and have a chat, tell them what you want to do with it. That's often the best way to cut down to what you need. Spares and support seem to be pretty good also.

The falcon is probably your best bet.

The Saab SeaEye Falcon is one of the products we have in mind. But also, we are opened for other possiblities, so, please, could you tell me if you have in mind another type of small ROV that can be deployed by hand from small boats (our largest is 9 meters long). Do you think that inertial navigation or DVL can help for positioning underwater? How other ROVs solve the issue of positioning underwater, especialy under the influence of currents?

Thanks!

Do you want to deploy Falcon by HAND from your 9m long boat?

Yes, in their comparison chart, Saab says the simple Falcon weights 60 kilos in air and the Falcon DR 100. We guess that 60 kilos is not that of a problem for two strong men and a boat with 4300 kilograms displacement.
