ABSTRACT:
An offshore well drilling assembly includes a drilling facility or support platform for location at sea. A drilling platform connects to the support platform so the drilling platform is cantilevered from the support platform. The drilling platform extends from the support platform, for positioning over a subsea well. The well drilling assembly includes a staging platform for use in loading and unloading of wellhead equipment. The staging platform is mounted to the drilling platform. The staging platform moves along a side of the drilling platform in directions toward and away from the support platform to a distance over the sea. A method of conveying wellhead equipment uses the staging platform for conveying wellhead equipment between the support platform and a distance over the sea by moving the staging platform along the drilling platform.
