Above the main cabin sits a wheelhouse featuring forward and aft control stations, with DP controls at the aft station that provides views of the cargo deck and offshore structures. Inflatable life rafts are situated outboard of the wheelhouse on each side of the vessel and are accessible for rapid deployment in case of an emergency.
