    This will probably sound like a grumpy old man’s rant but have ROV systems advanced any in the last 10 years specifically from the point of view of being able to do more or a do what we’ve always done in a better way? I’ve listed some of the changes that I’m sure we’ve all seen and would be interested to hear what everyone else thinks;

    – SIT cameras. Has anyone found a new low light camera that performs as well as an ‘old school’ tube SIT?

    – LED lighting. Good performance on paper but in reality if you flood one (and it will happen) can it be repaired in-field in the same way you can an incandecent light or is it back to manufacturer for most types?

    – DVRs. Has anybody found a decent replacement for the old Panasonic VCRs for ease of operation and simplicity in producing the client delverable video? The systems I have experience of have either shown reliabilty issues or have required the client video to be compiled ‘off-line’ (or both).

    -Touchscreens. Do these offer any advantage to the operator or just to the manufacturer who doesn’t have to pay someone to wire up a console worth of switches & pots?

    -System Diagnostics. Do any of the new systems have a diagnostic capapbility that truly assits those with limited technical experience or ability?

    -AHC Winches. The electric ones are great when they work but……..

    At the end of the day is a new Schilling UHD a better tool than a 10 year old Triton XL or would both systems get most jobs done in a similar time with equally experienced operators? Does the sophistication of newer systems work against them when trying to keep a system operational.

    Anyway, rant over. Stay safe everyone.

    Firstly, I believe there have been great leaps in ROV capability from top to bottom. The large WROVs needed to be designed to go deeper so needed to be more reliable as time taken to get to worksite and back can be several hours so downtime or lack of it is paramount. If you take the new XLX with their "Green Screen" which lets you see every part of the system is working prior to diving and if something goes wrong during the dive the screen will identify the fault. You can drill down to the datasheet for the component or connector etc and either bipass the fault to continue the dive or by the time you come to the surface the detail of the repair / fix is known and downtime is minimised.
    All of the smaller rov’s right down to the obs rovs have become more capable to take up the slack left by the larger rovs. Technology advances in thrusters, umbilicals and buoyancy give all rovs more grunt and load capacity and with lights cameras and tooling getting smaller all add up to modern Rovs being better than before. There is still a place in the market for the older systems though.

    AHC, I agree is still problematic and really depends od location of the motion sensors

    I agree with most of the comments of HPR, however with more reliable ROV’s also comes the problem that nobody knows what is under the hood… so to speak. So even simple troubleshooting becomes a bit of an adventure.

    As for winches have a look at http://www.lidanmarine.com/HOME.aspx

    They build winches for both small and large vehicles.
