I believe AET (American Eagle Tankers) handles the Galveston lightering Yokohoma’s now, for the most part, with a fleet of service vessels that tote them around.
I don’t know if they still do it but years ago we lightered to tankers of Sabine Pass. We did two trips loading from a SPM buoy off Bonny in Nigeria. The tankers had Yokohama fenders in davits. The first trip was OK. The second we had to get underway to provide a lee for the shuttle tankers in bad weather.
I can’t remember the year but I remember it was disastrous for Florida’s orange crop. The old man and third mate were on the bridge and the mate and I in the cargo control room, looking after mooring the tankers, discharge, ballast, crude oil washing etc. By the time we finished we had forgotten what a shower or a bunk looked like.
It doesn’t say anything about DPS equipment installed, but the Class notation NAUT-AW indicate that these SSVs have all the bells and whistles require.
Looking at their website, it looks like they took over the OMS vessels that handled the fenders. I seem to recall that they had some lightering tankers, too. All FOC vessels. I have been out of that part of the business for some time. . okay, decades. . . .
