I had one of the coolest job to evaluate marine life on offshore platforms with the BR2.
The client was really impressed with the ROV’s performances and the low cost / low logistics approach the BR2 setup allowed. Truck, plane, chopper and diving the same day.
Just running on battery and fiber optics for this one. I had a cargo limit due to accessing the site via chopper and I needed reach
The tether I brought is 450m long 6mm diameter. It took a serious beating (pinched, hooked, scrapping) and came out without a scratch. There was this one dive, the current was so strong after the dive 3 guys were pulling on it to recover the ROV.
The power module uses a 12mm diameter tether and for the same size spool I can only fit 200m. Hopefully next time I can bring it.
