The propulsion plant comprises two, electric-driven, RPM-controlled azimuth thrusters and two controllable pitch bow thrusters.

The vessel has dedicated tanks for 385 m3 potable water, 900 m3 fuel oil, 290 m3 base oil, 650 m3 liquid mud/brine, 1600 m3 ballast/drill water and 240 m3 cement in two segregated systems.
