HOS Bayou was retrofitted from a STX / VARD Tigershark 302 after delivery from Eastern. She’s absolutely configured for the GOM market, though could be an intermediate weight IMR vessel anywhere else working in up to 3000m of depth. She’s got power to spare with the addition of an aux machine room to support the 150 mt crane and the ROV’s. The retrofit included client accommodations for 20 above her internal 50. Bulbous bows don’t do anything for fuel consumption when you’re working, ie on DP, and transits in her designated operations area are relatively short.
Olympic Delta may have a lot of crew comfort but she’s got about half the crane capacity, half the dead weight, a third of the deck cargo, and 500m less wire.
