Here's something. It is the Stim Star Brasil, one of what are known in the business as "FRAC Boats", this one obviously owned by Edison Chouest, and operating in Brazilian waters. For those who might not know, this is one of a class of vessels which are used for well stimulation. Rather than  the whole insides of the planet being sucked out through pipes at oil wells, hydrocarbons are in fact filtering though the substrata and over time the filtering becomes less successful and so, in order to improve the flow, chemicals of one sort or another are pumped down the well at very high pressure. In Imperial measurement 15,000 psi is commonly used if there is pipework capable of withstanding it.
