ROV(Remotely operated vehicle )

I was lucky enough to involved in a subsea pipeline survey where i got chance to familiar a little submarine called ROV.It had manipulator arms,tracking frame,deep sea low light cameras,hydraulic thrusters for vertical and horizontal movements.And i remember it also had a beacon tramistters to retrive ROV incase of umbilical control cable was cut accidently.
There were 2 rov pilots in each shift and operated survey for days and nights.Is it sound interesting?right? yes it was.You would be mre interested if i could express how many teams were nvolved in such a survey operation.
Ok now i've got extra knowledge about ROVs by internet surfing.
There are moe than one ROV which is for subsea pipeline survey.So let me share info i got from other web sites.

The one i familiared was from CANYON,Norwaygian company.
What could we get from those called ROV(Remotely operated vehicle )?
We could inspect laid subsea pipeline situation like
1. cathodic protection system was properly function or not,
2.Visual inspection report can be obtained from professionals
2.How marine growths were growing on the pipeline or rig structures
3.How subsea pipeline could be moved because of seabed currents
4.How we can maintain suspended pipeline for prolong period and we can plan a schedule maintenance before unexpected shutdown occure
5.We could update our GPS location of pipeline
6.And seabed geographical map can also be obained by sonar system

2 ROV pilots operated ROV to inspect subsea pipeline .They were keeping controlling hydraulic thrusters to dive into water depth and came up to the surface.They operated manipulator arms to take test on anode joints.ROV was running on the pipeline with its 3 wheels underneath.Rolling and rolling until specific location was arrived to take test,took photos ,took video recording and commenting on what they were seeing on the tv screen.
You could enjoy seeing crowded underwater world like u have seen in discovery or NGC channels.Different kinds and size of marine animals were there.
Anywa,Its not a specific details about ROV,it's operation and experience onboard but atleast i can share something to those who have no idea at all.
I hope i can update and add more information when i have chance to get more information about ROVs.
