A triple activity drilling ship may be provided with two separate drilling centers, each including drilling apparatus. In addition, a trolley that is capable of supporting tubulars may be positioned between a first position within one of said drilling centers and a second position outside that drilling center. As a result, the trolley may be used to hold assembled tubulars while other activities are ongoing in one or more of the drilling centers.
