Abstract

A method and apparatus for positioning drilling equipment modules on an offshore platform apparatus which are removeably connected to the platform and adapted to contain equipment associated with the drilling of wells. A major portion of the equipment is secured to and within the modules and is simultaneously removeable with the modules as a unit when drilling operations on the platform apparatus have been completed. The drilling equipment modules are transported to a second location which may be either a jacket positioned on the ocean floor or a storage yard for future use of the modules on another platform. Alternatively, production equipment modules containing previously-installed equipment associated with the production of well fluids and being of a size and arrangement to be interchangeable with drilling equipment modules are subsequently lowered onto the platform apparatus next to the wellhead equipment modules after drilling operations on the platform apparatus have been completed.
