This photo has lain in my in tray for years because it is actually the Mac Tide "something", and it is just possible to see that there are a couple of numbers after the name, but it should be seen because the atmosphere of the GOM offshore environment has been captured so well. Possible numbers could be 48, 61 or 62, but whichever one it is it has either two of three propellers and is powered by about 7000 bhp of EMDs (probably).
Here is the veteran Skandi Hav offshore Brazil the other day. The ship started out as a pipe carrier after its construction at the Tronhjems Met Verksted yard in Norway in 1983 and some time ago was rebuilt as a well stimulation vessel and later re-assigned to Brazil. In 2014 it got another four year contract with Petrobras, so it must be doing a good job.
Back in the 1980s when it seemed as if the UT705 was just too big too elaborate and too expensive Ulsteins came up with the UT706 which was a slightly smaller version. It was therefore a bit cheaper, and so slightly more economical to run and possibly to hire. Although the last has never been particularly predictable, since shortages will ensure that high prices are commanded for even the most basic and unsuitable craft, and surpluses will ensure that operators are offered the latest, most complex and shiniest ships in the world at prices they can easily afford. So - here is the VOS Sympathy which has most recently been working in the wind industry, but was built in 1982 at Ulsteinvik as the Northern Fortress. Earlier this month it was snapped on its way to the breakers under tow from Ijmuiden.
