MT Indiga (Индига) is a Russian product tanker operated by Murmansk Shipping Company. After her modernization in 1994 she became the second merchant ship, after her sister ship Varzuga, to be equipped with an electric azimuth thruster, Azipod.

Lunni, built in 1976 by Werft Nobiskrug GmbH in Rendsburg, Germany, was the first ship of a series of four arctic product tankers ordered by a Finnish oil and petroleum products company Neste Oyj in the 1970s. The ships were given names after Finnish seabirds and the silhouettes of their namesake birds were painted on the side of the ships' superstructure. Lunni (Atlantic puffin) and Sotka (Aythya) were delivered in 1976 and Tiira (tern) and Uikku (grebe) in the following year. Until the 1990s the ships were used mainly to transport oil products in the Baltic Sea.

In 1993 Lunni made three consecutive voyages from Arkhangelsk to the Yana River in Siberia along the Northern Sea Route. The tanker was assisted by nuclear-powered icebreakers in the Vilkitsky Strait, but was under constant escort by Russian icebreakers only from Dikson Island to the Khatanga River.
