Seven is one of a kind

摘要

Since its introduction on the Bourbon Orca in 2006, Ulstein's signature inverted X-Bow has appeared on several vessel types either now in service or under construction. By far the most common is the PX105-type PSV, which accounts for 26 of the 62 X-Bow vessels. Ulstein's designations are quite simple, with the PX prefix covering PSVs, AX indicating AHTS vessels and SX reserved for specialist vessels.
