Subsea equipment (x-mas tree)

In Macaé (rio de Janeiro state) you'll find any type of equipment for Oil & Gas exploration, parked on public roads. Some equipments worth over US$ 250.000. Local traffic in town, or better to say, village is being dominated by flat deck trailers with heavy equipment and oversized loads.
I always look what kind of equipment is being transported, and from which company, just to keep informed who is doing business.
