Ships in registry counts individual vessel records attributed to the company here. Reported fleet is the company’s published total. They measure different things and are shown separately on purpose.
In context
Counts over companies and vessels actually held in this directory — not over the world fleet, which is larger. Nothing here is estimated.
With 1 vessels attributed to it here, Dolphin Drilling is the 492nd largest of the 965 operators in this directory that hold at least one ship on record, against a median of 2 across that group. That is a count of individually identified hulls, not the company’s published fleet size — the two are different measurements and both are shown above where available.
Norway is the country of registration for 150 commercial operators in this directory, among which Dolphin Drilling ranks 79th by ships on record. Between them those companies hold 831 vessels here. See every operator registered in Norway.
Founded in 1997, Dolphin Drilling is 29 years old. This directory holds 150 operators founded within five years either side of that date, whose median fleet on record is 1 ships. The median founding year across all commercial operators here is 1966, and the oldest on record dates to 1514.
