build up a number of companies to support DUC’s opera-
tions in the Danish North Sea. But Maersk Drilling, which
was established in 1972, quickly gained customers other
than DUC for its rapidly growing fleet of rigs. At the end
of 2011, Maersk Drilling employed around 3,000 people
and operated a total of 27 rigs worldwide. The fleet, which
comprised 12 jack-ups, five semi-submersible rigs and ten
drilling barges, made Maersk Drilling the world’s seventh
biggest operator in this area at this time.
In 1980, Maersk Drilling ordered construction of the
jack-up rig MÆRSK ENDEAVOUR by Rotterdam Dock-
yard Company for delivery in 1982. Given the hectic situa-
tion on the rig market at this time, the ink on the order was
not even dry before Maersk Drilling entered into a leasing
contract with DUC on the rig, which in 1982 was towed di-
rectly from the shipyard to the Tyra field, where the contract
was for the drilling of production wells for the field, where
production was due to commence in autumn 1984. During
its 25 years with Maersk Drilling, the MÆRSK ENDEA-
VOUR performed numerous tasks for DUC and entered the
Danish offshore history books in 1991 by being the first rig
to install a STAR platform. The rig further consolidated its
historic status via its participation in the discovery of the
Halfdan field in 1999. And it was also via a temporary in-
stallation on the MÆRSK ENDEAVOUR that DUC, barely
a year after the discovery of the Halfdan field, in February
2000 was able to start temporary production from the field
producing over three million barrels of oil even before the
permanent production platform was installed.
Together with two other Maersk Drilling rigs, the rig
was sold in 2007 to Northern Offshore, which was es-
tablished in 2000 and, at the end of 2011, was operating
three jack-up rigs, a semi-submersible rig, a drillship and a
floating production unit with assignments in Asia and Eu-
rope. The earlier MÆRSK ENDEAVOUR, now named the
ENERGY ENDEAVOUR, was the only one of Northern
Offshore’s rigs active in the Danish North Sea. As so often
happened during its time with Maersk Drilling, it was also
DUC’s operator Mærsk Olie og Gas which had jobs for the
well-known rig this time.

1983 samlet rådede over fem rigge. Foruden Maersk Dril-

DYVI EPSILON, og endelig DAN EARL, som Rederiet J.
