Engines and maneuvering
The ship is powered by six Wärtsilä 12V46C main engines giving an output of 75,600kW. The Mariner of the Seas has three azimuthing electric 14MW Azipod units. The two units on the sides are fully azimuthing whereas the one at the centreline is a fixed Azipod unit. There are also four 3MW bow thrusters.
The Mariner of the Seas has been designed to manage 40 knots side winds – where ships can normally stay manoeuvrable in 25-30 knots winds. To handle this, there are four 3MW tunnel thrusters in the bow. This gives the vessel a dynamic positioning capability so no anchoring is needed in sensitive coral areas. The wheelhouse has a cockpit-type navigation console, manned continuously by two officers.
